General Description
Oxyhemoglobin saturation is percentage of Oxyhemoglobin (O
2
Hb) capacity,
compounded with oxygen, by all combinativable haemoglobin (Hb) Oxyhemoglobin
(O
2
Hb) capacity in blood. In other words, it is consistence of Oxyhemoglobin in
blood. It is a very important ecological parameter for Respiratory Circulation System.
Many respiratory diseases can result in oxyhemoglobin saturation being lowered in
human blood. Moreover, the following factors can also lead to problems in oxygen
supply, so that human oxyhemoglobin saturation might be reduced: Automatic
Organic Regulation Malfunction caused by Anesthesia, intensive Postoperative
Trauma, hurts resulted in by some medical examination and etc. In the situation,
illnesses, such as dizziness, asthenia, emesis and etc, might happen to patients and
even endanger the patient's life. Therefore, it is very important to know
oxyhemoglobin saturation of patient timely in clinical medical aspects. So that
doctors can find problems in time.
