To investigate the effect of noninvasive positive-pressure respiration on acute myocardial infarction with acute pulmonary edema

Objective To investigate the effect of noninvasive positive-pressure respiration on acute myocardial infarction with acute pulmonary edema. Methods 43 patients of acute myocardial infarction with acute pulmonary edema received BiPAP mechanical ventilation treatment when the conservative treatment was not effective. Before and after treatment, the blood gas index, blood pressure, heart rate and breathing rate were recorded. Results Breathing rate, heart rate, blood pressure and the blood gas index of 40 patients were found to be significantly improvered after using BiPAP ventilation by nasal mask. The symptom of 3 patients deteriorated and changed tracheal intubation. The effiency rate of BiPAP ventilation is 93%. Conclusion BiPAP mechanical ventilation can more rapidly improved cardiac function, pulmonary edema and hypoxemia with acute myocardial infarction.
