Pumping,Intra Aortic Balloon | 《英文msh词典》Pumping,Intra Aortic Balloon | | [入口词] Pumping,Intra Aortic Balloon | | [主题词] Intra-Aortic Balloon Pumping | | [英文释义] 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. |
