US 2022/0023558 A1 · RESCUE BREATHING DEVICE

Abstract

A ventilation system for ventilation of a patient includes a patient interface device for attaching to the patient and a measuring and analysis device for measuring and analyzing breathing of the patient. The measuring and analysis device includes a connector housing defining a passage. A first portion of the connector housing is connected to the patient interface device. The measuring and analysis device further includes an air flow sensor and a pressure sensor disposed in the connector housing for measuring an air flow rate through the connector housing and a pressure in the connector housing respectively. The present device also includes a processor configured for data acquisition, data storage, data processing, and data output based on the air flow rate and the pressure, whereby the ventilation system is operable with real-time feedback based on the data output. A method for administering cardiopulmonary resuscitation is also provided.

Dependent claims

A ventilation system for ventilation of a patient, comprising:

a patient interface device for attaching to the patient;
and
a measuring and analysis device for measuring and analyzing breathing of the patient, the measuring and analysis device comprising:
a connector housing defining a passage, a first portion of the connector housing connected to the patient interface device;
an air flow sensor disposed in the connector housing for measuring an air flow rate through the connector housing;
a pressure sensor disposed in the connector housing for measuring a pressure in the connector housing;
a processor configured for data acquisition, data storage, data processing, and data output based on the air flow rate and the pressure;
and
an output device configured to output the data output,
wherein the ventilation system is used in cardiopulmonary resuscitation (CPR) comprising delivering rescue breaths to oxygenate the blood and chest compressions to circulate the blood, wherein the measuring and analysis device is operable to differentiate the rescue breaths from the chest compressions;
