Abstract

There is provided herein, a method for adjusting a VAD device parameters using a wearable device placed on the patient's hand, the method includes the steps of acquiring a set of signals from sensorsin the wearable device, computing at least one quality metric, and adjusting at least one VAD operational parameter so as to optimize at least the one quality metric.

Description

Background technique [0001] High blood pressure is a common condition in which the long-term force of the blood on the walls of the arteries is high enough that it may eventually lead to health problems such as heart disease. Blood pressure is determined by both the amount of blood pumped by the heart and the resistance to blood flow in the arteries. The more blood the heart pumps and the narrower the arteries, the higher the blood pressure. [0002] A person can have high blood pressure (called essential hypertension) for years without symptoms. Damage to blood vessels and heart continues and can be detected even when there are no symptoms. Uncontrolled high blood pressure increases the risk of serious health problems, including heart attack and stroke. High blood pressure usually develops over many years, and it eventually affects almost everyone. Fortunately, high blood pressure can be easily detected. [0003] Cardiovascular disease currently accounts for a significan...
