Description

Oxygen mask capable of being connected with end-tidal carbon dioxide test tube

Technical Field

The utility model relates to an oxygen mask capable of connecting a carbon dioxide end-expiration test tube.

Background

End tidal carbon dioxide (ETCO 2) monitoring has proven to be faster and more sensitive than peripheral oxygen saturation reactions, and can react to respiratory conditions in real time. The respiration of the patient can be determined by the waveform and the value of the end-tidal carbon dioxide, and the end-tidal carbon dioxide is used for guiding a doctor to adjust the oxygen supply of the patient during the anesthesia operation. The patient's end tidal carbon dioxide if the waveform is of a lower normal value, indicating that the patient may have excessive breathing or a gas exchange disorder condition; if the magnitude of the waveform reduction is low, indicating that the patient has respiratory depression; if the normal value of the waveform is high, the patient is indicated to be under-ventilated; so that the device can respond to the breathing condition of the patient more quickly and can process the breathing condition in time. The sedative condition of the patient can be judged through the waveform of the end-tidal carbon dioxide, and the sedative medicine can be adjusted in time. The respiratory depression of the patient is light during mild sedation, and the tidal volume is affected by no more than 10%; during moderate sedation, tidal volume of the patient can reach over 50% under influence; patient breathing may be completely inhibited during deep sedation.

However, only patients with tracheal cannula currently have end tidal capnography, while patients without tracheal cannula do not have end tidal capnography; the existing mode is that the end-expiratory carbon dioxide test tube directly stretches into the oxygen mask from the side edge of the oxygen mask, and the measurement result is not accurate enough.
