Title: Family presence during pediatric resuscitations

Category: Pediatrics

Keywords: debriefs, death, family (PubMed Search)

Posted: 10/16/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

Parental presence during pediatric resuscitation is supported by family-centered care principles and AHA guidelines, yet implementation remains inconsistent due to divided provider attitudes and a lack of institutional policies.

Methods: Qualitative exploratory descriptive study across three Iranian pediatric hospitals. Semi-structured interviews were conducted with 33 resuscitation team members (nurses and physicians) and 20 parents who experienced their child's resuscitation. Thematic analysis identified key patterns. Of 16 resuscitated children, 87.5% died.

Conclusions: Parental presence is not a binary choice but requires preparation, support, and shared decision-making. The authors recommend formal institutional policies, staff simulation training, designated family support persons, and structured pre-briefing and debriefing protocols.

Show Additional Information

Key Findings — Two Main Themes:

1. Double-edged sword of parental presence (provider perspective)

Reluctance: Providers cited performance pressure, fear of misinterpretation, procedural disruption from emotionally overwhelmed parents, staffing shortages, and concern about psychological harm to families.

Permission: Presence was allowed case-by-case when parents were calm, familiar with the child's condition, or when survival was unlikely — framed as ethically necessary for closure.

2. Emotional weight of parents' decision to be present (parent perspective)

Choosing presence: Most parents viewed being present as a moral duty — to protect, ensure adequate care, and say goodbye. Exclusion generated mistrust and anxiety.

Indecision: Some parents who witnessed resuscitation later experienced intrusive traumatic memories; those who chose absence experienced lasting regret. Both choices carried enduring psychological consequences.

Title: Predictors of clinically significant underlying etiologies in children presenting with acquired torticollis

Category: Pediatrics

Keywords: torticollis, neck pain, fever (PubMed Search)

Posted: 9/18/2026 by Jenny Guyther, MD (Updated: 9/18/2026)

This was a retrospective review of children < 18 years who presented to the pediatric emergency department with torticollis in a single center over a 6 year period.

Clinically significant underlying etiologies included infection, tumor, or atlantoaxial rotary fixation requiring surgery (AARF).

352 children with a median age of 4.8 years presented with torticollis and 59 were found to have a significant underlying etiology.

Children with infectious causes were younger and more likely to be febrile and have an elevated CRP.  Infections included retropharyngeal abscess, lymphadenitis and cervical spine osteomyelitis.  AARF was associated with prolonged symptoms, older age, midline tenderness and restricted motion.  Tumor related cases often featured additional red flag symptoms such as headache and vomiting and symptom duration ranging from 5 days to 3 months.

Title: Is EMS documentation of bystander CPR accurate?

Category: EMS

Keywords: 911, dispatch, CPR, bystander (PubMed Search)

Posted: 9/16/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

The national cardiac arrest registry includes information on bystander CPR.  An EMS clinician currently enters bystander CPR (B-CPR) information into the prehospital care report.  The accuracy of this documentation has not been validated.  This study compared EMS documented B-CPR rates to the bystander CPR rates on the 911 audio recordings of the calls in Birmingham Alabama.

Show Additional Information

EMS documentation in the Birmingham CARES registry recorded a B-CPR rate of only 12.3%, while review of corresponding 9-1-1 audio recordings identified a substantially higher rate of 27.5% — more than double the EMS-documented rate.

Of 236 adult non-traumatic out-of-hospital cardiac arrest (OHCA) cases analyzed, 56 cases (23.7%) had disagreements between EMS documentation and 9-1-1 audio review, while 180 cases (76.3%) were concordant. 

In 46 of the 56 discordant cases, 9-1-1 audio confirmed that B-CPR was performed but EMS did not document it. The majority of these involved callers who initiated CPR but discontinued it before EMS arrival, making it invisible to arriving crews. Only 7 of these 46 appeared to be outright EMS misclassifications.

In 10 cases, EMS documented B-CPR but the 9-1-1 audio did not support it — all involved calls that ended before EMS arrival without cardiac arrest recognition or CPR instruction by the dispatcher

Bottom line: Sustained telecommunicator CPR instruction matters through EMS arrival,  as early caller discontinuation of CPR was the primary driver of undercounting, and better dispatcher engagement could both improve CPR continuity and documentation accuracy.

Title: TXA use in pediatric post tonsillectomy hemorrhage

Category: Pediatrics

Keywords: Tonsillectomy, bleeding, TXA, peds (PubMed Search)

Posted: 8/21/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

This multicenter, retrospective study used the Pediatric Health Information System database to examine TXA (Tranexamic acid) use for post tonsillectomy hemorrhage (PTH) across US children's hospitals, analyzing 19,572 ED encounters for PTH in children <18 years from 2016–2024.  The study did not differentiate TXA by route of administration or doses.

TXA use is rapidly increasing but remains highly variable. Median annual TXA use rose dramatically from 0.0% in 2016 to 30.6% in 2024, yet individual hospital-level use ranged from 1.0% to 67.1%, reflecting a lack of standardized protocols and significant practice variation across institutions.

TXA was associated with reduced reoperation but not hospital admission. At the encounter level, TXA administration was associated with 34% lower adjusted odds of reoperation (aOR 0.66, 95% CI 0.56–0.77). However, there was no significant association with hospital admission (aOR 0.93, 95% CI 0.83–1.04).

Title: STARS Program

Category: EMS

Keywords: EMS dispatch, pediatrics, special needs (PubMed Search)

Posted: 8/19/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

The STARS (Special Needs Tracking and Response System) program was started in 2014 to bridge gaps in caring for children with special health care needs in the prehospital setting.

Since its inception, it has evolved into a hospital based, physician lead program with individualized EMS care plans stored on an electronic server and accessible to units responding to these patients.

In addition to the development of patient specific plans that are not within the local EMS protocol, this program has led to targeted EMS training and improved interdisciplinary care coordination.  This program has also shown a decrease in EMS transports to the hospital.

The program started with 14 patients in one EMS jurisdiction and has now expanded to 2424 patients across 3 states.  As the program expands, there is an aim to expand these care plans to include disaster preparedness, such as back up plans for patients dependent on electricity and plans to access critical medications during emergencies.

Title: Fluids in Pediatric Septic Shock

Category: Pediatrics

Keywords: Fluids, normal saline, lactated ringers, plasmalyte, sepsis (PubMed Search)

Posted: 7/17/2026 by Jenny Guyther, MD (Updated: 7/17/2026)

The PRoMPT BOLUS trial (Pragmatic Pediatric Trial of Balanced versus Normal Saline Fluid in Sepsis) is the largest randomized controlled trial to date comparing balanced crystalloids to 0.9% normal saline in children with septic shock. The primary outcome showed no significant difference in major adverse kidney events at 30 days between the two groups.  The secondary outcome showed  no significant difference in 30 or 90 day mortality.

Show Additional Information

PRoMPT BOLUS was a pragmatic, open-label, multicenter RCT conducted across 47 emergency departments in five countries. Children aged 2 months to <18 years with suspected septic shock and abnormal perfusion were randomized to receive either balanced fluid (lactated Ringer's or PlasmaLyte) or 0.9% saline for up to 48 hours. 

Primary Outcome

The primary endpoint was a major adverse kidney event (MAKE) within 30 days — a composite of death, new renal-replacement therapy, or persistent kidney dysfunction. Among 8,482 patients analyzed:

Balanced fluid group: 137/4,073 (3.4%) experienced a MAKE event

0.9% saline group: 124/4,068 (3.0%) experienced a MAKE event

Risk ratio: 1.10 (95% CI, 0.88–1.40; P = 0.85) — no significant difference

Secondary Outcomes

No differences were observed in any secondary effectiveness endpoint:

30-day mortality: 1.0% vs. 0.9% (RR 1.07; 95% CI, 0.70–1.64)

90-day mortality: 2.3% vs. 2.1% (RR 1.07; 95% CI, 0.80–1.42)

New renal-replacement therapy: 0.6% vs. 0.7% (RR 0.84; 95% CI, 0.50–1.42)

Hospital-free days at 28 days: median 23 in both groups

While the primary outcome was neutral, balanced fluids demonstrated more normal lab values:

Hyperchloremia (Cl >110 mEq/L): 31.4% vs. 49.0% (RR 0.64; P < 0.001)

Hypernatremia (Na >155 mmol/L): 1.8% vs. 3.1% (RR 0.60; P = 0.003)

Hyperlactatemia (lactate >4 mmol/L): 19.8% vs. 16.7% (RR 1.18; P = 0.04) — slightly higher in the balanced fluid group, likely reflecting the lactate content in LR

No differences were seen in thrombosis, cerebral edema, hyperkalemia, or hypercalcemia between groups

Title: Cardiac Arrest During Interfacility EMS transport

Category: EMS

Keywords: SADS, cardiac arrest (PubMed Search)

Posted: 7/15/2026 by Jenny Guyther, MD (Updated: 7/15/2026)

This study by Peters et al. (2026), published in Prehospital Emergency Care, is the first nationwide analysis of cardiac arrest occurring during interfacility transport (IFT) by EMS, finding that critical care transport (CCT) was associated with more than double the odds of ROSC compared to ALS (aOR 2.21, 95% CI 1.42–3.48), while BLS care was associated with significantly worse outcomes.

Overall ROSC rate: 50.3% — broken down as 32.9% (BLS), 45.3% (ALS), and 59.5% (CCT)

Show Additional Information

From over 54 million EMS encounters, they identified 1,466 cases where cardiac arrest was witnessed by the transporting EMS crew during an IFT.

Key Descriptive Findings

Level of care distribution: 7.5% BLS, 53.6% ALS, 38.9% CCT

Median age: 64 years (IQR 50–75); CCT patients were younger (median 61) than BLS (70) or ALS (66)

22.2% had a shockable initial rhythm

11.8% were trauma-associated

9.2% had a prior cardiac arrest before re-arresting during IFT — most commonly in the CCT group (14.9%), reflecting the higher acuity of patients selected for CCT

58.1% were transported by ground; 38.2% by rotor wing; 3.7% by fixed wing

14.7% involved a mechanical CPR device

Unshockable Rhythm Subgroup Analysis

A particularly notable finding was that the CCT advantage persisted — and was even more pronounced — in patients with unshockable initial rhythms (PEA/asystole):

CCT vs. ALS: aOR 2.65 (95% CI 1.64–4.33)

BLS vs. ALS: aOR 0.47 (95% CI 0.21–1.03, borderline non-significant)

Ground vs. air: aOR 0.61 (95% CI 0.38–0.97)

The authors hypothesize this reflects CCT clinicians' ability to titrate multiple vasopressors — particularly important for managing pseudo-PEA associated with profound hypotension — as well as the benefit of having a second clinician in the patient compartment enabling parallel task completion and redundant monitoring.

Title: IM vs IN Midazolam for Pediatric Seizure Control

Category: Pediatrics

Keywords: status epilepticus, benzodiazepine, seizure (PubMed Search)

Posted: 6/19/2026 by Jenny Guyther, MD (Updated: 6/19/2026)

This was a metanalysis which included 5 studies of 3933 pediatric patients requiring seizure management without IV access, mostly in the prehospital setting.

Bottom line: IM midazolam appears superior to IN midazolam as a first-line non-IV benzodiazepine for pediatric seizures in the prehospital setting, though IN remains a clinically effective alternative — particularly when caregiver acceptability and ease of administration are prioritized.

Show Additional Information

IM midazolam reduced the need for rescue therapy compared to IN midazolam in pediatric seizures (RR 1.29, 95% CI 1.15–1.45), a finding consistent across prehospital subgroups and studies using the standard 0.2 mg/kg dose.

IM midazolam terminated seizures ~24 seconds faster than IN midazolam (MD 23.60 s, 95% CI 2.31–44.89; p = 0.03).

Title: Characteristics of pediatric medical out of hospital cardiac arrests in Vienna

Category: EMS

Keywords: cardiac arrest, EMS, international (PubMed Search)

Posted: 6/17/2026 by Jenny Guyther, MD (Updated: 6/17/2026)

This was a retrospective study of the pediatric cardiac arrests over a 5 year period (including COVID years) in Vienna.  

Infants (<1 year) had the highest incidence of OHCA among all pediatric age groups, consistent with German registry data showing an incidence of 23.4 per 100,000 in this age group.

Non-shockable rhythms (asystole/PEA) predominated, as expected given that most pediatric OHCA results from progressive respiratory failure or shock rather than primary cardiac causes.

Survival to hospital discharge remained low, consistent with international data showing pediatric OHCA survival ranging from 6.6% for infants to 17.3% for adolescents in the US CARES registry.

Bystander CPR rates and witnessed arrest status were important modifiable factors associated with improved outcomes, aligning with findings from the adult Vienna cohort where witnessed arrests with shockable rhythms had substantially higher survival (39% vs. 9.3% overall).  

The study highlighted that even in a high-resource, physician-staffed EMS system, pediatric OHCA outcomes remain poor, underscoring the importance of primary prevention and early bystander intervention

Title: What factors are associated with ED discharge after an arrival by helicopter EMS in pediatric patients?

Category: EMS

Keywords: HEMS, pediatric trauma (PubMed Search)

Posted: 5/21/2026 by Jenny Guyther, MD (Updated: 5/21/2026)

Previous pediatric studies have shown that 1) air transport has shown improved outcomes compared to matched ground transports but 2) air transport may be overutilized.

This was a multicenter retrospective study using the Pediatric Emergency Care Applied Research Network Registry from 2012-2021 looking at pediatric patients transported to the ED by helicopter.  This registry does not differentiate between field transports and interfacility transfers. The study looked to identify patients who were discharged from the ED or had a hospital stay < 48 hours.  7722 patients were included with a median age of 5.9 years.  20% of these patients were discharged from the ED.  Among those admitted, over half were discharged within 48 hours.  Patients who were discharged from the ED were found to have triage < ESI 1, missing a systolic blood pressure or temperature.  Tachycardia, tachypnea, hypertension and abnormal temperature were associated with a lower rate of ED discharge.

Bottom line: Additional research is needed to identify patients who may be more appropriate for ground transport or when transport is not needed (or could be replaced with telemedicine).

Title: Is there an ideal initial dose for pediatric defibrillation?

Category: Pediatrics

Keywords: CPR, ILCOR, PALS, VF, defibrillation (PubMed Search)

Posted: 5/15/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

US and International guidelines differ on the initial defibrillation dose in pediatric patients.  International, European, Australian and New Zealand guidelines had recommend an initial dose of 4 J/kg for the initial and all subsequent doses while the American Heart Association recommends an initial dose of 2-4J/kg (with 2 J/kg in the teaching algorithms) with subsequent shocks being at least at 4J/kg and no greater than 10 J/kg.   More recently, ILCOR suggested an initial dose of 2-4 J/kg.

This was a systemic review of 7 observational studies, mostly involving in hospital pediatric cardiac arrests.  Outcomes of termination of VF/pVT, ROSC and survival to hospital discharged were examined in relation to the initial J/kg dose that was used compared to initial doses of 2 J/kg.  Outcomes were neither better or worse with doses < 1.5 J/kg or > 2.5 J/kg.  Additional research is needed as this certainty of this evidence was considered “very low.”

Title: What are the signs of traumatic pancreatitis in the pediatric patient?

Category: Pediatrics

Keywords: Abdominal trauma, CT, lipase (PubMed Search)

Posted: 4/17/2026 by Jenny Guyther, MD (Updated: 4/17/2026)

Pancreatic injury in pediatric blunt abdominal trauma is rare. 

This study was a secondary analysis of the data collected by the Pediatric Emergency Care Applied Research Network (PECARN) in the Intra-abdominal Injury Study Group. Of the children who had blunt abdominal trauma, 6% had intraabdominal injuries and 1% had pancreatitis.  A patient was considered as having traumatic pancreatitis if they had 2 of the following: 1) upper abdominal tenderness, 2) serum lipase of amylase > 3 x the upper limit of normal or 3) imaging study positive for pancreatitis.

Show Additional Information

Children diagnosed with pancreatitis were more likely to report abdominal pain, vomiting, shortness of breath, thoracic trauma and handlebar injury compared to those without a diagnosis of pancreatitis.  On exam, they were more likely to be hypotensive, tachypneic, evidence of abdominal wall injury, costal tenderness, abdominal distention and abdominal tenderness.  When the PECARN prediction rule was applied to these patients, the sensitivity was 99% with a specificity of 42%.  The rule missed one patient who had traumatic pancreatitis, but this patient did not meet the definition for clinically important abdominal injury (requiring therapeutic laparotomy, embolization, blood transfusion or requiring IV fluids for > 2 days).

Title: Can EMS safely decide which child requires a cervical collar?

Category: EMS

Keywords: MVC, c-spine injury, PECARN, rules (PubMed Search)

Posted: 4/15/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

Cervical spine injuries (CSI) are uncommon in children, but when present, they are often devastating.  However, the application of a cervical collar in children is not benign and adverse effects include neck pain and discomfort and the downward tunnel vision it may create at the hospital leading to unnecessary testing.  Recently, the PECARN group published a set of criteria to determine who requires imaging of the cervical spine in the emergency department.  A planned subset of this initial study was to collect the impressions of EMS as they pertained to the 9 criteria to determine if these criteria could safely be used by EMS.  The patients who were brought in by EMS with the potential for cervical spine injury, who were evaluated by the trauma team and/or had cervical imaging AND had electronic case reports filled out by EMS were included in the final analysis.  Only 57% of the patients possible could be included based on the number of electronic case reports that were filled out.

Show Additional Information

Overall, when the criteria were applied to the EMS patients based on the EMS assessment, the PECARN CSI had a sensitivity of 88.5%, a specificity of 63.1%, a PPV of 3.7% and a NPV of 99.7%.

Of 122 patients, 14 patients who did have CSI were not detected.  Further analysis of these missed patients showed that 11 of the patients did have one of the 9 criteria present which was documented by the ED but not by EMS.  Only one of the 14 missed patients required operative intervention.  12/14 of these patients were from motor vehicle collisions.

The study criteria did perform better in the ED setting compared to the EMS setting.  Further research will need to examine if these clinical criteria can be applied to the field or if they should be modified to increase the specificity.

Keywords: Complications, intubation, pediatric (PubMed Search)

Posted: 3/20/2026 by Jenny Guyther, MD (Updated: 3/20/2026)

This was review of 24 studies across 21 years that aimed to look at the complications associated with pediatric intubation in the hospital.  The article also includes a list of all the articles with brief conclusions from each study for those interested. 

Among a combined 7135 patients, there was an 84.7% overall success rate with a 30.1% rate of complication.  There was a 69.8% first pass success rate.  Desaturations < 90% was the most common complication followed by mainstem intubation.  Studies also noted cardiac arrhythmia (55/3858 patients), hypotension (121/4536 patients) and cardiac arrest in 105/4836 patients).  Other adverse events included esophageal intubation, surgical airway management and airway trauma.

Indications for intubation from most to least common are: neurologic, respiratory, trauma, cardiac arrest, sepsis, shock, cardiac failure and intoxication.

Title: IV vs IO epinephrine in pediatric OOHCA – is there a winner?

Category: EMS

Keywords: IV, IO, epi, arrest, delivery (PubMed Search)

Posted: 3/18/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

The debate of the best way to administer epinephrine in cardiac arrest continues.  Pediatric arrests are different from adults in many ways, but some differences in arrest include 1) data supporting improved survival with early epinephrine administration and 2) less IVs are placed in children overall compared to adults making IO placement possibly quicker.

In this study, 739 patients were included with a median age of 1 year.  The IO was used in 72% of patients and an IV was used in 27.6% of patients.  There was no difference between survival to hospital discharge or prehospital ROSC between the two groups.

Title: Socioeconomic Differences in Pediatric Out of Hospital Cardiac Arrest

Category: Pediatrics

Keywords: OOCA, race, poverty, peds (PubMed Search)

Posted: 2/20/2026 by Jenny Guyther, MD (Updated: 2/20/2026)

Bottom line: Socioeconomic differences in outcomes of cardiac arrest are present in the pediatric population as well and CPR education and resources should be present in ALL communities.

Show Additional Information

Previous studies have shown that socioeconomic differences are seen out of hospital cardiac arrests in adults.  This study investigates these differences in the pediatric population. 

This was a retrospective cohort study of the Cardiac Arrest Registry to Enhance Survival looking at out of hospital cardiac arrests in patients < 18 years.  An index score was developed including race, household income, high school graduation rates and unemployment rates with a score of 4 representing the highest risk neighborhoods.  Children from the areas with the highest risk score had lower odds of survival to hospital discharge and neurologically favorable survival compared to the lowest risk neighborhoods. 

In the 6945 pediatric arrests included, 33% occurred in black children, 31% in white children and 10% in Hispanic children.  41% of the arrests occurred in the highest risk neighborhoods.  Black children had a lower odds of survival to hospital discharge (OR 0.73) and discharge with neurologically favorable outcome (OR 0.64) compared to white children.  Hispanic children did not have any worse survival outcomes compared to white children.  This data also fits in with other studies that have shown children from high risk neighborhoods and black children as less likely to receive bystander CPR compared to white children and children in low risk neighborhoods.

Title: What are the delay's in telecommunicator recognition to pediatric out of hospital cardiac arrest?

Category: EMS

Keywords: CPR, pediatric, T-CPR, dispatch, public safety (PubMed Search)

Posted: 2/18/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

Bottom line: Education to the public is needed to help to improve the information relayed to telecommunicators in an emergency.  Further telecommunicator education can help to overcome the barriers within their control, such as the recognition of agonal breathing.

Show Additional Information

An important step in the chain of survival in cardiac arrest is recognition of an emergency.  When a person calls 911, the telecommunicator needs to be able to obtain the necessary information to direct the right resource to the right patient and be able to deliver directions for CPR if required.  

This study looked at 911 calls for pediatric patients who were in cardiac arrest on EMS arrival in Denmark over a 3 year period and identified 3 barriers to the recognition of the arrest by the telecommunicator. 

  1. Prolonged conversations focused on the cause of the child's condition as opposed to assessmening consciousness and breathing.

  2. Assessing breathing when the patient has irregular or agonal breaths

  3. Callers who were unable to communicate or follow instructions from the telecommunicator.

Title: What is the ideal initial defibrillator pad placement in out of hospital cardiac arrests?

Category: EMS

Keywords: VT, VF, shockable, pad placement (PubMed Search)

Posted: 1/21/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

The European resuscitation council recommends AL (anterior-lateral) pad positioning while the American Heart Association recommends AL or AP (anterior-posterior) pad placement for defibrillation.

This was a prospective cohort study over a 4 year period in a single EMS jurisdiction.  Adult patients with a medical cardiac arrest with an initial rhythm of VT/VF were included.  The primary outcome was ROSC at any period of time.

Patients with AP pad placement (compared to AL) had a higher adjusted odds ratio of ROSC at any time (1.34), but not statistically different odds of pulse in the ED, survival to hospital admission or discharge, or functional status at hospital discharge.

The AP pad placement group also required less shocks on average and had earlier and initial sustained rates of ROSC.  Further research is needed with respect to initial pad placement in the cardiac arrest population.

Title: Does a negative CXR exclude bacterial pneumonia in children?

Category: Pediatrics

Keywords: PNA, CXR (PubMed Search)

Posted: 1/16/2026 by Jenny Guyther, MD (Updated: 10/19/2026)

This was a retrospective study at a tertiary pediatric emergency department over a 10 year period.  Authors sought to determine the number of patients who developed radiographic pneumonia after an initial normal CXR. 

9957 patients with suspected pneumonia were included.  240 had an additional CXR within 14 days and 27 (11% of those with a 2nd CXR) had developed PNA on the CXR.  Overall, the rate was 1/370 children went on to have radiographic PNA in the next 14 days after an initial CXR.  Tachypnea, hypoxia and dehydration at the initial visit were shown to be associated with later development of PNA on CXR.

Title: Improving pediatric CPR quality

Category: Pediatrics

Keywords: CPR, peds, ventilation, BVM, compression ratio (PubMed Search)

Posted: 12/19/2025 by Jenny Guyther, MD (Updated: 10/19/2026)

Pediatric CPR without an advanced airway in place requires 15 compressions to 2 ventilations per AHA and ILCOR guidelines.  This can lead to a 2-4 second pause in compressions due to the time the ventilations take.  The Maryland hiccup method is a novel description of two brief pauses for ventilations during the upstroke of compressions 14 and 15.  This method was shown to improve the compression fraction and compressions per minute with no significant differences between standard CPR and the Maryland hiccup method in ventilation volume or compression depth determined on simulation mannequins.  38 Maryland EMS clinicians participated in this study.

A video demonstration of the Maryland Hiccup method is linked in the article and also available at: https://www.youtube.com/watch?v=RvFxhj7hzsQ .
