Detection of progressive central hypovolemia

摘要

A system for detecting dehydration, hemorrhaging, and increases in blood volume comprising monitors the time difference between the arrival of the primary left ventricular ejection pulse (pulse T1) and the arrival of the iliac reflection (pulse T3) to determine an arterial pulse parameter which is the time difference between T1 T3. Changes in T3 minus T1 are indicative of something happening to blood volume. If the T1-3 value goes up and the patient is on an infusion system, it can be an indication of having too much fluid pumped and if T1-3 is lower than it should be for an individual, they are either dehydrated (which can result in decreases in blood volume), they are hemorrhaging, or they have hemorrhaged. A downtrend in T13 can tell whether someone is continuing to hemorrhage

主权项

1. The method of determining blood volume and/or dehydration in an animate being, comprising the steps of:
measuring the time difference between the arrival of a first pulse and the arrival of a second pulse, said time difference between the arrival of said first pulse and said second pulse, said first pulse and said second pulse being pulses whose time difference corresponds to blood volume in said animate being.
