What device is inserted into the femoral artery to increase blood pressure by exerting counter pressure?

The intra-arterial balloon pump is a medical device specifically designed to assist patients experiencing severe cardiac conditions, such as heart failure or cardiogenic shock, where maintaining adequate blood pressure is critical. When inserted into the femoral artery, the balloon pump inflates and deflates in synchrony with the patient's heartbeat.

This process generates counter pulsation, which effectively increases blood flow to the coronary arteries during diastole (when the heart muscles relax) and decreases the workload on the heart during systole (when the heart pumps). By applying counter pressure, the device helps to improve perfusion to vital organs and enhances overall blood pressure stability.

In contrast, intubation refers to placing a tube in the airway for ventilation, which is not related to blood pressure management. The term "hemato block" is not a standard device or procedure recognized in this context. Laminectomy is a surgical procedure for spinal decompression and does not influence blood pressure directly. Thus, the intra-arterial balloon pump is clearly the appropriate choice for the question regarding increasing blood pressure through counter pressure.
