Intraaortic Balloon Pump:
A device used to augment coronary artery circulation, which occurs predominantly during diastole. The device is inserted via the femoral artery proximally into the thoracic aorta, with its tip placed just distal to the origin of the left subclavian artery. The device will also measure invasively the aortic pressure at its catheter tip. The tip contains an air-inflated balloon, which inflates automatically during diastole by detecting the dicrotic notch via the pressure monitor and ECG. The level of augmentation may be adjusted according to the desired ratio of augmented:non-augmented diastole and the strength of augmentation. Strong augmentation may lead to aortic diastolic pressures which are higher than systolic pressures, and are misrepresented by the normal invasive intraarterial blood pressure monitor. Therefore, when augmentation is used, the blood pressure should be read from the ballon pump catheter for accuracy.
Cell Saver:
A device used during off-pump surgery. During surgeries utilizing the heart lung machine, blood lost by bleeding may be returned to the patient via the pump sucker into the venous reservoir. In off-pump surgery, this machine performs this function instead, by using blood sent to a tank via a sucker and delivers output similar to a pack cell transfusion into an infusion bag, which may then be used to return blood to the patient.
