Cardiac arrest
Airway pressures during manual vs mechanical CPR
Mean airway pressure as the missing link in CPR physiology: A prehospital comparison of manual and mechanical chest compressions
The American Journal of Emergency Medicine · Added 27 July 2026
Prehospital mPAW values were substantially lower than those reported in previous ED-based studies.
- Study type
- Other
- Design
- Prospective exploratory pilot observational study
- Participants
- 19 adults with OHCA (10 manual, 9 mechanical compressions)
- Main finding
- Median initial mean airway pressure was 7.74 mbar; higher early with mechanical (8.96 vs 6.54 mbar); ROSC patients had higher mPAW but not statistically significant
- Caveat
- Very small sample, single Belgian service, exploratory
- Bottom line
- Hypothesis-generating
Learning goal
Strengthen my understanding of how airway pressures during chest compressions influence ventilation and perfusion in cardiac arrest.
