Podcast 735: End Tidal CO2 and BiPAP

Podcast 735: End Tidal CO2 and BiPAP

Contributor: Aaron Lessen, MD

Educational Pearls:

  • End tidal CO2 is accurate to 1-4 mmHg in intubated patient but use with those on positive pressure ventilation like BiPAP is unclear
  • Study looked at patients on BiPAP for COPD or CHF and found end tidal CO2 measurements were significantly underestimated when compared to VBG levels
  • End tidal CO2 measurements for those on positive pressure ventilation appears to be inaccurate
