Abstract

The invention provides a technique to apportion tidal volume during a delivery breath from an anesthesia machine ventilator. The technique includes an apportioned volume indicator. The apportioned volume indicator provides visual indication of method to apportion tidal volume during delivery breath from the anesthesia machine ventilator. The basic assumption of the indication is that a system is able to measure a raw tidal volume to be delivered out of the system or tidal volume inspired. Secondly, to measure the raw tidal volume that is returned to the system. Thirdly, to measure amount of volume that does not reach the patient lungs due to compliance of the patient breathing circuit. Fourthly, to measure amount of volume that is lost due to sample line of respiratory gas monitor (RGM) which pulls gas from the patient breathing circuit.

A VISUAL APPORTIONED VOLUME INDICATOR AS AN INDICATION OF TIDAL VOLUME TO BE APPORTIONED DURING DELIVERY OF BREATHE FROM AN ANESTHESIA MACHINE VENTILATOR

 FIELD OF INVENTION

The invention generally relates to an anesthesia machine ventilator and more particularly to an apportioned tidal volume indicator for anesthesia machine ventilator.

BACKGROUND OF THE INVENTION

Generally, a user determines whether a patient is efficiently ventilated and in certain cases whether patient is adequately ventilated. A visual indication shows problem with the user set up as well as a system problem.


Hence, there exists a need for an efficient technique to deliver breath for adequate ventilation to the patient.

BRIEF DESCRIPTION OF THE INVENTION

The invention provides a technique to apportion tidal volume during a delivery breath from an anesthesia machine ventilator. The technique includes an apportioned volume indicator. The apportioned volume indicator provides visual indication of method to apportion tidal volume during delivery breath from the anesthesia machine ventilator.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides a technique to apportion tidal volume during a delivery breath from an anesthesia machine ventilator. The technique includes an apportioned volume indicator. The apportioned volume indicator provides visual indication of method to apportion tidal volume during delivery breath from the anesthesia machine ventilator.

Delivery of breath is provided from the anesthesia machine ventilator and also from manual, mechanical and/or support means. As a result, a user determines, in a glance, whether a patient is ventilated efficiently and in certain cases, whether the patient is adequately ventilated.  The apportioned volume indicator takes on many forms, which include a bar, bar graph, pie chart and/or text. FIG. 1 depicts different graph utilized as apportioned volume indicator.

Typically, any visual forms of displaying percentage of “the whole” are utilized. The basic assumptions of the indication are that a system is able to measure a raw tidal volume to be delivered out of the system or tidal volume inspired. Secondly, the system is able to measure the raw tidal volume that is returned to the system. Thirdly, the system is able to measure amount of volume that does not reach the patient lungs due to compliance of the patient breathing circuit. Fourthly, the system is able to measure amount of volume that is lost due to sample line of respiratory gas monitor (RGM) which pulls gas from the patient breathing circuit. FIG. 2 depicts portion of the visual indication.

FIG. 2

The full indicator or “the whole” represents every measured inspiratory tidal volume sent from the anesthesia machine to the patient. The inspiratory tidal volume does not include any tidal volume compensation, which includes RGM gas monitor sample uptake compensation, leak compensation and circuit compliance compensation. “The whole” represents r...
