The current recommendations for cardiopulmonary
resuscitation (CPR) incorporate the following major changes:
Open chest CPR is two to three times
more effective than closed chest CPR.
Closed chest CPR works more by the 'thoracic
pump' mechanism than by the 'cardiac pump'.
A higher ventilation rate with chest
compression performed during positive
pressure ventilation generates greater intrathoracic pressures and therefore
Higher doses of adrenaline increase brain
and coronary blood flow.
Calcium is detrimental.
