CPAP and PEEP

Specialties MICU

Published

I'm doing our high acuity clinicals this quarter and I'm having a problem w/ the mechanical vent modes. I cannot figure out the difference between CPAP and PEEP. I've searched it on some websites and on here but... I'm getting contradictory information. Some sites say there's no difference but that CPAP is a more accurate term. Other sites say that CPAP is used in patients who able to spontaneously breathe and PEEP is used for patients on mechanical vents. And yet someone else I asked (resp therapist) said CPAP was used continously (insp and exp) and that PEEP is used during exhalation only. So confused...

According to my instructor, there IS a difference... And I don't understand her when she's trying to answer my question. She doesn't explain the difference. Please help. My exam is Monday...

Thanks
