What is the function of oximeter?

The oximeter detects blood oxygen, which is a non-invasive operation. It can effectively monitor the blood oxygen in the body and play a key role in predicting the change of the disease, mainly taking finger pulse oxygen as the monitoring index. If there is atherosclerosis or vascular blockage, there is lipid deposition in the vascular cavity, and the peripheral blood circulation is not smooth, which will easily lead to hypoxia. Understanding blood oxygen content with oximeter also indirectly reflects cardiovascular and cerebrovascular diseases. Improving coronary angiography and cerebral angiography as soon as possible can help us understand the situation and make reasonable treatment plans to prevent myocardial infarction and cerebral infarction. At the same time, it should be noted that finger pulse oxygen clamping for a long time is easy to affect fingertip blood circulation due to local compression or cold weather, resulting in misjudgment. It can be re-monitored after soaking in warm water to improve the accuracy of detection.
