Medical device for detecting pulmonary artery pressure
First Claim
Patent Images
1. A medical device to monitor pulmonary artery pressure (PAP) of a patient, comprising:
- a first detector configured to measure and determine a first parameter (SVR) indicative of a right ventricular stroke volume of the patient'"'"'s heart;
a second detector configured to measure and determine a second parameter (ERR) indicative of speed of blood ejected from a right ventricle of the patient'"'"'s heart; and
a processing unit configured to determine a pulmonary pressure index (IP) by combining the first and second parameters, with variations of the pulmonary pressure index indicating variations of PAP.

Abstract
In a medical device and method to monitor pulmonary artery pressure of a patient, a first parameter related to the right ventricular straight volume of the patient'"'"'s is detected, and a second parameter related to the right ventricular ejection rate of the patient'"'"'s heart, or related to the workload of the patient'"'"'s heart, is also determined. A pulmonary pressure index is determined by combining the first and second parameters, with variations of the pulmonary pressure index indicating variations in the pulmonary artery pressure. Pulmonary artery hypertension can be monitored with such a device and method.
