Blood oxygen is the concentration of oxygen in the blood. Oxygen enters the blood vessels and is carried by hemoglobin, which carries oxygen and distributes it to various tissues.
The combination of hemoglobin and oxygen is similar to a train with more compartments, the compartments are hemoglobin-carrying oxygen, some hemoglobin is not loaded with oxygen, the compartment fullness is equivalent to the blood oxygen saturation, and a normal person can usually reach about 98%. If there is a decline, can lead to hypoxia, is the daily used to monitor the body is not hypoxia in the easiest indicators.
Precautions for oxygen monitoring
The plug of the oxygen probe and the oxygen jack of the main panel must be plugged in place. Otherwise, it may not be able to collect oxygen information and display the oxygen and pulse values.
The patient's fingernails should not be too long and should not have any stains, dirt or gray nails. If the patient's finger becomes uncomfortable after a long period of oxygen monitoring, it should be replaced with another finger.
Patients and healthcare workers should also refrain from bumping and pulling the probe and wires to prevent damage that could affect its use.
