Treatment of nasal(facial) mask Bi-level positive airway pressure ventilation for acute myocardial infarction with acute left ventricular failure

Objective To observe the efficacy of nasal(facial) Bilevel mask positive airway pressure(BiPAP) ventilation for acute myocardial infarction with acute left ventricular failure.Methods 58 patients were treated by nasal(facial)BiPAP accessory machines when the conventional treatment was not effective.The changes of heart rate,blood pressure and arterial blood gas were recorded accurately before and after the treatment.Results The heart rate,blood pressure,arterial blood gas and clinical symptoms of 58 patients had been improved significantly(P0.05 or P0.01).The efficacy was 100%.Conclusion The use of BiPAP mechanical ventilation therapy is safe,effective,it can be the conventional treatment of acute myocardial infarction with acute left ventricular failure.
