Method for rising PaCO2, acquisition device, monitor system and medical treatment purpose

Abstract

The invention relates to the field of medical treatment equipment, and discloses a method for improving PaCO2, an acquisition device, a monitor system and medical treatment purpose. The system comprises an autologous CO2 suction PaCO2 rising device, and a breath acquisition device, a signal acquisition device, a communication interface module, a signal processing device and a display device, which are connected sequentially. After the system is adopted, the non-invasive detection of the cerebrovascular reserving function is realized, the result is accurate and reliable, and the clinical practicability is high. The invention has the following advantages that: the financial burden of patients is relived; the risk of cross-infection is eliminated; the risk of CO2 anesthesia is eliminated; it is easy to monitor the PaCO2 accurately; and gas at mouths and noses in a face mask are exhaled by the patients, the collected gas is not influenced by outside, and the change of ETCO2 can be reflected really, so that the change of the PaCO2 can be monitored accurately.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for increasing the PaCO of the subject. 2 method, ETCO 2 Signal acquisition device, cerebrovascular reserve function monitoring system and its medical application. Background technique [0002] Cerebrovascular reserve (CVR), also known as cerebral blood flow reserve, cerebral circulation reserve, etc., refers to the expansion or contraction of cerebral arterioles and capillaries under the stimulation of physiological or pathological factors to maintain the stability of cerebral blood flow or regulate cerebral blood flow. Flow to meet the needs of brain function. Its functional impairment plays an important role in the pathogenesis of ischemic cerebrovascular disease and is an independent risk factor for ischemic stroke. Therefore, the correct detection and evaluation of CVR can provide a useful reference index for the diagnosis and treatment of ischemic cerebrovascula...

AI Technical Summary

Problems solved by technology

Can effectively change PaCO 2 , but different concentrations of CO 2 The gas needs to be specially customized in the oxygen plant, and the higher CO 2 Concentration gas has CO 2 risks of anesthesia

and CO 2 Gas inhalation and ETCO 2 The gas collected by monitoring is at the patient's mouth and nose, resulting in ETCO 2 The monitoring value is greatly affected by

[0008] In view of the above prior art raising PaCO 2 Insufficiency of the method makes the current detection method of cerebrovascular reserve function unable to meet the clinical needs
