Embodiment Construction

[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] like figure 1 as shown,figure 1 It is a flowchart of a carbon dioxide partial pressure monitoring method in an embodiment of the present invention, the method comprising:

[0049] Step S10, obtaining arterial blood carbon dioxide partial pressure PaCO 2 and end-tidal partial pressure of carbon dioxide EtCO 2 ;

[0050] In this embodiment, a blood gas analyzer is used to perform invasive arterial blood carbon dioxide partial pressure PaCO 2 Measure and collect the respiratory airflow through the probe to obtain the end-tidal partial pressure of carbon dioxide EtCO 2 . In this embodiment, only one invasive measurement is required, and the measured value is used as a reference for the subsequent estimated value, and the respiratory airflow is collected before and after the invasive measurement, so as to obtai...

Abstract

The invention discloses a monitoring method and a device for partial pressure of carbon dioxide. The monitoring method for partial pressure of carbon dioxide comprises the steps: acquiring arterial carbon dioxide pressure PaCO2 and end-tidal carbon dioxide pressure EtCO2; and determining the estimated value of arterial carbon dioxide pressure PaCO2' at the measurement time according to the arterial carbon dioxide pressure PaCO2 and end-tidal carbon dioxide pressure EtCO2. According to the invention, the number of invasive measurement to a human body is reduced, the pain of a person to be measured is alleviated, the monitoring of partial pressure of carbon dioxide is more safe, the estimated value of corresponding arterial carbon dioxide pressure can be quickly obtained by the end-tidal carbon dioxide pressure EtCO2, the blood and vigor status of the human body is dynamically reflected in real time, and the monitoring of the arterial carbon dioxide pressure is quicker and more visual.

Description

technical field [0001] The invention relates to the field of respiratory system monitoring, in particular to a carbon dioxide partial pressure monitoring method and device. Background technique [0002] COPD (chronic obstructive pulmonary diseases, chronic obstructive pulmonary diseases) is an important cause of death and disability. It is currently the fourth leading cause of death in the United States and Europe. Its treatment guidelines advocate early detection and implementation of martial law programs to help reduce Morbidity and disease mortality. Early detection of COPD includes blood gas analysis of patients, such as PaCO 2 Invasive measurement of (arterial carbon dioxide pressure, partial pressure of carbon dioxide in arterial blood), that is, measuring the tension generated by physically dissolved carbon dioxide in arterial blood through arterial puncture to measure alveolar ventilation. However, the operation of invasive measurement is inconvenient, the detectio...
