Refers to pulse oxygen is the use of finger pulse oxygen meter to detect human blood oxygen, check for hypoxia symptoms. Hypoxia has a huge impact on the body. For example, the impact on the CNS, liver and kidney function. The first thing that occurs during hypoxia is compensatory heart rate acceleration, increased heart rate and cardiac output, and the circulatory system compensates for the lack of oxygen in a high-power state. At the same time, blood flow redistribution occurs, and the brain and coronary vessels are selectively expanded to ensure adequate blood supply. However, in severe hypoxic conditions, ATP synthesis is reduced due to accumulation of lactic acid under the endocardium, resulting in myocardial inhibition, resulting in bradycardia, premature contraction, decreased blood pressure and decreased cardiac output, and arrhythmia such as ventricular fibrillation. Even stop.

Basic Information

Specialist Category: Inspection Category: Other Inspections

Applicable gender: whether men and women apply fasting: not fasting

Tips: Check your relaxation, you should face it positively and actively cooperate with the inspection. Normal value

It is generally considered that the normal should be no less than 94%.

Clinical significance

Abnormal results:

Below 94%, below 94% is insufficient oxygen supply. A disease with insufficient blood oxygen supply.

Even stop.

The people who need to be examined are: people with symptoms such as dizziness and dizziness.

Precautions

Taboo before the test: Do not eat too greasy, high-protein foods the day before the test, to avoid heavy drinking. The alcohol content in the blood directly affects the test results.

Requirements for inspection: No substantial movement during inspection.

Inspection process

Use your finger pulse meter to gently pinch your fingertips for a few seconds.

Cerebral oximetry is characterized by invasive blood sample testing and the use of non-invasive pulse oximetry to detect arterial oxygen saturation in the finger and ear lobe. Monitoring cerebral blood oxygen parameters in this manner does not accurately reflect the brain in real time. Changes in the blood oxygen parameters of the tissue.

Not suitable for the crowd

Generally no taboos.

Adverse reactions and risks

Generally not.
