Podcast 517: It's all about the PEEP

Contributor: Dylan Luyten, MD

Educational Pearls:

  • Bag-valve masks (BVM) typically have a port to connect O2 to. Unfortunately room air becomes entrained in the mask, reducing the FiO2 delivered to the patient. This can be overcome by using a PEEP (positive end-expiratory pressure) valve on the BMV
  • PEEP valves function by keeping alveoli open in the lungs at the end of expiration. This increases the oxygen diffusing ability of the lungs, keeping patients' oxygen saturations higher.
  • Patients who are critically ill can become quickly hypoxic after RSI meds due to reduced functional residual lung capacity - an issue that can be overcome with a PEEP valve
  • PEEP also will reduce work of breathing in COPD and CHF patients
