Monitoring Left Ventricle End Diastolic Pressure
First Claim
1. Apparatus for monitoring the left ventricle end diastolic pressure of a person comprising,an inflatable band for covering the artery of a person and applying a predetermined pressure to the artery of the person through the inflatable band,a pressure transducer in the inflatable band for providing a waveform signal representative of the pressure in the artery covered by the inflatable band when the inflatable band is pressurized at a pressure level within a range for providing a pressure waveform signal representative of the pressure in the artery,and a waveform transmitter for transmitting the pressure waveform signal to a central location for processing the transmitted signal to provide an LVEDP signal representative of LVEDP of the person being monitored.

Abstract
Apparatus for remotely monitoring the left ventricle end diastolic pressure of a person includes an inflatable band for covering the artery of the person and applying a pre-determined pressure to the artery through the band. A pressure transducer in the inflatable band provides a pressure waveform signal representative of the pressure in the artery covered by the inflatable band. A waveform transmitter transmits the pressure waveform signal to a central location for processing the transmitted signal to provide LVEDP signal representative of the left ventricle end diastolic pressure of the person.

6. A method of monitoring the left ventricle end diastolic pressure of a person remote from a central station comprising,
applying an inflatable band over the artery of a person at the remote location and applying a predetermined pressure to the artery with the inflatable band, performing a Valsalva maneuver for a predetermined time interval and then resting to establish a pressure waveform representative of the LVEDP of the person, transmitting the pressure signal waveform to the central location, receiving the transmitted pressure waveform signal at the central location, and processing the pressure signal waveform received at the central location to provide a signal representative of the LVEDP of the person.
