Dyspnea in the Intubated Patient
- Dyspnea may occur in up to 50% of intubated patients and has been associated with prolonged mechanical ventilation.
- A number of assessment tools are available to detect dyspnea in the intubated patient.
- Regardless of the tool used, once dyspnea is diagnosed, consider the following;
- When possible, reduce nonrespiratory stimuli of the respiratory drive (i.e., fever, acidosis, anemia)
- Minimize respiratory impedance (i.e., bronchodilators, thoracentesis for pleural effusion)
- Optimize ventilator settings (i.e., change modes if applicable, increase inspiratory flow, increase PEEP)
- Pharmacologic treatment (i.e., opioids, benzodiazepines)
