In conclusion, multiple components of cardiopulmonary resuscitation generate high concentrations of respiratory aerosol.
Study context
- Population
- Humans with OHCA undergoing CPR; porcine cardiac arrest model
- Participants

Time-averaged aerosol concentration during ventilation, porcine model, vs before cardiac arrest
- Defibrillation and chest compressions generate high aerosol independent of, but synergistic with, ventilation
