Opander Cpr [LATEST]

While a metronome helps, Opander adjusts for fatigue. As a rescuer tires in minutes 2-3, the rate often slows. The Opander system increases the volume of the "thump" sound to accelerate the rescuer back to 110 BPM.

Standard closed-chest CPR (CCC) generates only 10–30% of normal cardiac output. After 10 minutes of CCC, cerebral perfusion pressure falls below the threshold for viability. – direct manual compression of the heart after thoracotomy – produces near-normal cardiac output (50–100% of baseline) and higher coronary perfusion pressure. opander cpr
