1. Whether the patient has proper colloid osmotic pressure and blood volume. Proper colloid osmotic pressure and adequate blood volume are among the key factors in maintaining normal oxygen saturation shown on the Adult Finger Clip SpO2 Sensor.
2. What is the patient’s cardiac output? The amount of oxygen delivered to maintain normal organs should be supported by sufficient cardiac output.
3. Microcirculation of tissues and organs. Whether to maintain proper oxygen and also related to the metabolism of the body, when the body’s metabolism is too large, the venous blood oxygen content will be significantly reduced, and the venous blood will lead to more severe hypoxia after the shunted pulmonary circulation.
4. Utilization of oxygen in surrounding tissues. Tissue cells can only use free oxygen, and oxygen combined with Hb can only be released for tissue utilization. Changes in PH, 2,3-DPG, etc. affect the dissociation of oxygen from Hb.
5. After eliminating all of the above factors, don’t forget that it may be due to a drop in oxygen saturation caused by Adult Finger Clip Sensor malfunction.
