Embodiment Construction

[0048] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] The oxygen supply parameter monitoring method disclosed in the present invention is specifically implemented as follows:

[0050] The oxygen supply parameter monitoring method disclosed in the present invention includes the following steps:

[0051] Step 1. Pass Hb-SO placed in the esophagus 2 The sensor detects the optical density OD of blood in the adjacent descending aorta through the esophageal wall and the optical density change △OD, the Hb-SO 2 The sensor emits three near-infrared light with different wavelengths;

[0052] Step 2. Calculate the change in the concentration of reduced hemoglobin in the blood ΔC using formula (1) and formula (2) HHb , Oxygen and hemoglobin concentration changes

[0053] ΔC H H b = e HbO 2 λ 2 ...

Abstract

The invention discloses a method for monitoring oxygen supply parameters.The optical density (OD) and optical density optical density changing quantity (delta OD) of blood in adjacent descending aortas are detected through an Hb-SO2 sensor arranged in an esophagus via the esophagus wall, and the hemoglobin concentration of blood is obtained through corresponding calculation.The invention further discloses an adopted detecting device.The hemoglobin concentration and even oxygen supply of a patient in the perioperative period can be subjected to routine monitoring like monitoring of SpO2, the oxygen supply of the patient can be kept within a safe range to avoid anoxia injuries and greatly improve the safety of anesthesia and an operation, and meanwhile the effort saving functions of reducing the use frequency of complex invasive monitoring and reducing the work intensity of an anesthetist are achieved.

Description

Technical field [0001] The invention relates to the medical field, in particular to a detection method and a detection device for oxygen supply parameters. Background technique [0002] Perioperative blood loss and cardiopulmonary dysfunction can all lead to a decrease in the body's oxygen supply. Real-time monitoring and maintenance of oxygen supply is the best strategy to prevent oxygen debt and hypoxic injury during the perioperative period. Oxygen supply is based on the clinician's actual cardiac output ( CO), arterial oxygen saturation (SaO 2 ) And hemoglobin content (Hb) three different measurement results to estimate the body’s milliliters of oxygen per minute. Except SaO 2 In addition to conventional pulse oximetry monitoring, CO is a special monitoring, which requires a special pulmonary artery floating catheter or PiCCO catheter. There are high risks and costs, and sufficient time is required. Hb can only be obtained by blood sample analysis. At present, there is no me...
