[主題詞] Intra-Aortic Balloon Pumping
[中文釋義] 泵,主動脈內氣囊
[英文釋義] Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates,it raises aortic diastolic pressure,and as it deflates,it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
