Studies in patients with cardiac arrest outside hospital have consistently found that epinephrine increases aortic relaxation pressure and increases coronary perfusion pressure, increasing the chances of achieving ROSC.
The coronary perfusion pressure flow relationship for heart is summarized in Figure 2(a).
Level of NOS in coronary perfusion effluents was determined using an NOS assay kit (Nanjing Jiancheng Bioengineering Institute, Nanjing, China) with a spectrophotometer (Bio-RAD, USA) at 530 nm according to manufacturer's instructions with modifications as described by Ma et al.
Our study indicated that human PAMP did not significantly alter the coronary perfusion pressure, heart rate and contractile force (p>0.
Substantial interruptions of chest compressions have detrimental effects on the success of cardiopulmonary resuscitation (14-16), reducing the likelihood of success of defibrillation due to immediate declines of coronary perfusion (15,17,18).
High-quality compressions and coronary perfusion pressures correlate with end-tidal carbon dioxide (ETCO2) levels of 20-25 mm Hg on capnography.
Cardiac-only resuscitation may be more efficient than CPR because with an open airway, gasping and passive chest recoil provide some air exchange, or mouth-to-mouth ventilation could take time away from the chest compression needed for supporting cerebral and coronary perfusion, they suggested.
However, those studies involved follow-up of only 6-24 months' duration--not long enough for the early hazards of percutaneous intervention or coronary artery bypass surgery to be outweighed by the longer-term benefits of the resultant improved coronary perfusion.
The rate doesn't provide adequate coronary perfusion.
