Podcast 808: BVM and PEEP Valve

Podcast 808: BVM and PEEP Valve

Contributor: Dylan Luyten, MD

Educational Pearls:

  • Positive End Expiratory Pressure (PEEP) is positive pressure within the lungs and maintained throughout the entire respiratory cycle. It is the pressure preventing alveoli from collapsing at the end of exhalation.
  • When using a bag valve mask (BVM) to ventilate patients, always attach the PEEP valve to prevent intrathoracic pressure from returning to atmospheric pressure which would allow alveoli collapse.
  • A BVM with a good seal to patients face and with an attached PEEP valve provides the same support as BiPAP or CPAP.
  • A generally acceptable PEEP setting is 5 cmH2O.
