GAS MONITORING APPARATUSES, METHODS AND DEVICES

摘要

This disclosure provides gas monitoring apparatuses, methods and medical devices. A gas monitoring apparatus can include a gas concentration monitoring module, a respiratory mechanics monitoring module and a correction module. The correction module can determine a first correction value based on the gas ingredients and the gas concentration measured by the gas concentration monitoring module, so that the respiratory mechanics monitoring module can correct respiratory mechanics parameter(s) based on the first correction value. The correcting module can also determine a second correction value based on the pressure-related quantity measured by the respiratory mechanics monitoring module, so that the gas concentration monitoring module can correct gas concentration based on the second correction value.

主权项

1. A gas monitoring apparatus, comprising:
a gas concentration monitoring module for extracting gas from a patient's airway, and measuring and outputting gas ingredients and gas concentration; a correction module that is connected with an output port of the gas concentration monitoring module for obtaining the gas ingredients and the gas concentration outputted by the gas concentration monitoring module; wherein the correction module is capable of determining a first correction value based on the gas ingredients and the gas concentration, and outputting the first correction value; and a respiratory mechanics monitoring module for measuring at least one respiratory mechanics parameter within the patient's airway; wherein the respiratory mechanics monitoring module is connected with an output port of the correction module for receiving the first correction value outputted by the correction module; and wherein the respiratory mechanics monitoring module is capable of correcting the respiratory mechanics parameter based on the first correction value using a first pre-set correction scheme and outputting the corrected respiratory mechanics parameter.
