There is no relationship between oxygen saturation and blood pressure. Although both have indicators about blood, the indicators monitored are different. Oximetry refers to the amount of oxygen in the blood. Under normal circumstances, arterial oxygen saturation should be greater than 95%. Oxygen saturation is the most sensitive indicator to monitor the presence of oxygen deprivation in patients. Oxygen saturation is not related to blood pressure in any way and does not affect oxygen saturation regardless of blood pressure. Blood pressure is the pressure of blood on the blood vessel wall, blood pressure is an important indicator to maintain blood flow, only in the presence of blood pressure, blood can flow normally; if blood pressure disappears, blood will also stop flowing.
