Problems solved by technology

Unfortunately, it is often difficult to identify patients with hypopulsatility, such as those with implanted type blood pump patients) MAP
For example, a traditional commercial blood pressure cuff (cuff) may fail to detect a patient's pulse pressure because the pulse signal is not strong enough to provide a stable blood pressure reading
As a result, patients may be exposed to medical complications that could otherwise be managed or prevented through accurate blood pressure measurement

Abstract

An implantable blood pump system including a blood pump, an impeller in communication with the blood pump, and a controller in communication with the blood pump. The controller is configured to measure a current drawn by the blood pump and a blood flow from the blood pump during operation, correlate the current to a systolic arterial pressure and a diastolic arterial pressure, and adjust a speed of the impeller relative to a predetermined speed and the blood flow to correspond to an increase in the current correlated to the systolic arterial pressure and a decrease in the current correlated tothe diastolic arterial pressure.

Description

technical field [0001] The present disclosure relates to a method and system for operating an implantable blood pump and measuring a patient's blood pressure with the implantable blood pump. Background technique [0002] Implantable blood pumps provide mechanical circulatory support to patients with weakened or otherwise damaged hearts. Typically, implanted blood pumps include a pumping mechanism that moves blood from the heart to the rest of the body. In operation, the blood pump draws blood from a source, such as the right ventricle, left ventricle, right atrium, or left atrium of the patient's heart, and propels the blood into the aorta, such as the patient's ascending aorta or peripheral arteries. [0003] Patients requiring implanted blood pumps often have underlying heart problems, such as low pulsatility. In general, pulsation reflects the contraction and extension of the heart, and the volume of blood moved by the heart. As a result of hypopulsatility, medical com...
