SUPRASYSTOLIC MEASUREMENT IN A FAST BLOOD-PRESSURE CYCLE

摘要

Disclosed herein is a system for monitoring a patient that includes a cuff configured to inflate to at least partially occlude an artery of the patient and a cuff controller configured to inflate the cuff during a dynamic phase and generally maintain inflation of the cuff at about a target pressure during a static phase. The system also includes a sensor configured to receive a signal associated with the at least partially occluded artery and generate an output signal based on the received signal, and a cuff control module configured to determine the target pressure during the dynamic phase and based on the output signal, and control the cuff controller during the dynamic phase and the static phase.

1. A method of manufacturing a measurement system, comprising:
providing a cuff; providing a cuff controller to inflate the cuff to at least partially occlude an artery of a patient during a single dynamic phase; configuring the cuff controller to maintain inflation of the cuff about a target pressure during a static phase, wherein the target pressure is a suprasystolic pressure; providing a first sensor to acquire a signal associated with the at least partially occluded artery; and providing a signal analysis module configured to determine a parameter based on the signal from the first sensor, wherein the parameter is determined based on a fist set of data obtained over more than two cardiac cycles during the single dynamic phase and a second set of data obtained during the static phase, the second set of data being obtained over a defined number of cardiac cycles immediately following the beginning of the static phase.
