Oxygen saturation (medicine) Wikipedia

Oxygen saturation is the fraction of oxygensaturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 95–100 percent. If the level is below 90 percent, it is considered low and called hypoxemia.

Accuracy of pulse oximetry in the intensive care unit

Objective: Pulse oximetry (SpO2) is a standard monitoring device in intensive care units (ICUs), currently used to guide therapeutic interventions. Few studies have evaluated the accuracy of SpO2 in critically ill patients. Our objective was to compare pulse oximetry with arterial oxygen saturation (SaO2) in such patients, and to examine the effect of several factors on this relationship.

Understanding SpO2 and Normal Oxygen Levels

Sep 28, 2016· SpO2, also known as oxygen saturation, is a measure of the amount of oxygencarrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently. In fact, very low levels of SpO2 can result in very serious symptoms.

How do I track blood oxygen saturation (SpO2) with my ...

SpO2 values naturally vary, and nighttime SpO2 is usually lower than daytime SpO2 due to the fact that your breathing rate is usually slower during sleep. In general, SpO2 values during sleep are typically above 90%. The SpO2 values presented are an estimate and in general can be influenced by your activity, altitude, and overall health.

Can an Oximeter Help Detect COVID19 at Home? | Houston ...

Aug 12, 2020· An SpO2 of 100% has effectively zero clinical difference to a 96% reading. As a good rule of thumb, a person with COVID19 monitoring his or her clinical status at home will want to ensure that the SpO2 reading stays consistently at or above 90 to 92%. If the number consistently drops below this threshold, timely medical evaluation is warranted.

How to Interpret Pulse Oximeter Readings

SpO2 (blood oxygen saturation levels) of a healthy person should fall in between 94% and 100%. Supplementary oxygen should be used if SpO2 level falls below 90%, which is unacceptable for a prolonged period of time. Medicare will pay for oxygen therapy and oxygen equipment if your SpO2 readings are below 88%.
