Problems solved by technology

Alternatively, the clinician may provide or continue to provide supplemental oxygen when supplemental oxygen is not required or desired (e.g., the addition of supplemental oxygen may increase the inaccuracy of the measured capnogram, making it difficult or impossible to accurately analysis of capnograms or information related to them)

Abstract

A capnography system (100, 400), comprising: a controller (110, 410) configured to obtain a sample gas flow from a physical interface (107) for a patient (101); determine a change in a characteristic of the sample gas flow during a sampling time interval; determine whether the change in the characteristic of the sample gas flow during the sampling time interval is equal to or greater than a corresponding threshold value;determine that supplemental oxygen is provided when it is determined that the change in the characteristic of the sample gas flow is equal to or greater than the threshold value; and determine that supplemental oxygen is not provided when it is determined that the change in the characteristic of the sample gas flow is less than the threshold value.

Description

technical field [0001] The present system relates to a capnography system for detecting the presence or absence of oxygen in ventilation gases obtained from a physical user interface, for example for detecting oxygen in the sidestream of a ventilation flow configured to be coupled to a spontaneously breathing patient systems that exist, and how they operate. Background technique [0002] In general, nasal capnometry can be used to detect periods of slow breathing and / or hypopnea in patients who may be suffering from hypoventilation (eg, patients taking certain medications). For example, pain medications and / or sedative medications can temporarily reduce a patient's desire and ability to breathe, which may lead to hypoventilation. Some reduction in breathing is acceptable for short periods of time when supplemental oxygen is administered by nasal cannula or oxygen mask. Unfortunately, clinicians often forget to administer supplemental oxygen to patients when it would be ben...
