Intrathoracic Airway Closure Impacts CO2 Signal and Delivered Ventilation During Cardiopulmonary Resuscitation

What is it about?

During cardiac arrest, the small airways in the chest tend to close impeding the delivery of adequate ventilation and resuscitation. We show here that the signal of expired carbon dioxide at the mouth (usually monitored during resuscitation) can become a guide for detecting this phenomenon and apply positive pressure.
