Abstract
Members of the first Department of Internal Medicine, Hyogo College of Medicine elaborated the noninvasive circulatory assistant apparatus for the treatment with myocardial infarction.
The device is consisted of three large rubber bags fitted.around lower part of the abdomen and bilateral lower extremities.
Positive Pressure is added with the compressed air flowing into the bags to the lower half of the body during diastole and loosened during systole with negative pressured air.
Cardiac output increased from 3.6 (±0.9) to 4.1 (±0.9) liter per minute and mean pulmonary capillary wedge pressure decreased from 23 (±9) to 17 (±7) mmHg.
These results may indicate that external counterpulsation is effective in improving the hemodynamics of severe acute myocardial infarction.
