Cardiac arrest & resuscitation
Methods for calculating ventilation rates during resuscitation from out-of-hospital cardiac arrest
Authors' conclusion
Quantifications of hypo- and hyperventilation vary with the applied measurement methods.
Study context
- Population
- Patients with out-of-hospital cardiac arrest (OHCA) in the Pragmatic Airway Resuscitation Trial, ventilations identified from capnogram recordingsdata available for 1,010
- Participants
- 3,004 patients
- Comparison
- Counted vs Measured
- Primary endpoint
- Estimated total hypoventilation (ventilation rates (VR) <6 breaths/min) and hyperventilation (VR >12 breaths/min) by measurement method and time epoch
