<p>A cardiopulmonary rosuscitator (10) comprising a reciprocatabie cardiac compressor means (12-19) for cyclically compressing a patient's chest and a ventilating means (26, 27, 96) for inflating the patient's lungs to a benign limiting pressure such as between 10 and 60 cm of water over a period encompassing at least one and preferably three cycles of the compressor means. The resuscitator includes ventilator output control means (45, 51, 54) for (i) preventing retrograde and exhale flow from the patient's lungs during the systolic portion of the cycle of the compressor means thus providing for a pressure increase in the patient's lungs due to compression of the patient's chest to a level well above that of the limiting pressure, for example to between 75 and 200 cm of water, and (ii) periodically venting the patient's lungs, for example for two cycles of the compressor means.</p> |
