Blood Pressure in the Critically Ill Obese Patient
- Recall that incorrectly sized cuffs can significantly overestimate blood pressure, especially in obese patients.
- In fact, some studies show that false BP readings can occur in up to 75% of obese patients.
- By relying solely on noninvasive BP measurements, many of your critically ill obese patients may actually be hypotensive and under perfused.
- When you've got a sick obese patient, strongly consider early placement of an arterial line to assess and monitor blood pressure.
