Forward blood flow during cardiopulmonary resuscitation (CPR) is believed to be the result of direct compression of the heart (“cardiac pump”) and intrathoracic pressure (ITP) differences (“thoracic pump”). The relative contribution of both mechanisms is unknown.
Delta-CP varied greatly within and between patients. Ventilation pressure had a significant augmentation effect on delta-CP.
Further studies are needed to confirm that the augmentation of delta-CP by higher airway pressures is associated with improved cardiac output, and to study the influence of higher airway pressures on, for example, venous return.
No relevant competing interests disclosed.
