Since the normal SpO2 max is ~98%, due to physiological demands/metabolism, it would be the accuracy of the equipment that produced a 100% reading. Typically, pulse oximitry has an accuracy of +/- 2%.
The CPAP machine itself does not control your SPO2 or oxygen saturation, so there is no part that controls this. Simplified, SPO2 is the amount of oxygen, expressed as a percent, found in the blood. Your optimal SPO2 is determined during your sleep study. The RT or Polysomnographer that performed your sleep study would adjust your pressure, measured in centimeters of water, to determine what decreases your apnea events while keeping your SPO2 as optimal as possible. This is called titrating. So essentially the oxygen saturation is controlled by the pressure setting that is determined by your physician as your therapeutic level or range. If by using a pulse ox monitor, you have determined that your SPO2 is dropping while using your CPAP machine, you should discuss these finding with your physician because a new sleep study may be required.

Decreasing spo2 signifies - decreased efficiency of lungs to absorb enough oxygen, required to have normal gaseous exchange.
To estimate a PaO2 from an SpO2 reading, you can use the oxygen-hemoglobin dissociation curve as a reference. However, keep in mind that this relationship is not linear and may vary depending on factors such as altitude, pH, and temperature. If you need an accurate PaO2 measurement, it is best to directly measure it using an arterial blood gas (ABG) test.

The normal SpO2 rate in the US is typically around 95-100%. This means that the blood is carrying a healthy amount of oxygen to the body's tissues. If SpO2 levels drop below 90%, it may indicate a potential breathing or circulation issue.
SpO2 stands for peripheral capillary oxygen saturation. It is a measure of the amount of oxygen-saturated hemoglobin in the blood, expressed as a percentage. SpO2 is commonly measured using a pulse oximeter, a non-invasive device that clips onto a person's finger to monitor their oxygen levels in real-time. It is an important indicator of respiratory function and overall oxygenation in the body.

SPO2 or pulse oximetry
SpO2, or peripheral capillary oxygen saturation, is a measure of the percentage of oxygen-saturated hemoglobin in the blood compared to the total hemoglobin. It is typically measured using a pulse oximeter, a non-invasive device that attaches to a finger or earlobe. Normal SpO2 levels generally range from 95% to 100%; levels below this can indicate inadequate oxygenation and may require medical attention. Monitoring SpO2 is crucial in various clinical settings, especially for patients with respiratory or cardiovascular conditions.

SpO2 measures the amount of oxygen in the blood, while VO2max measures the maximum amount of oxygen a person can use during intense exercise. SpO2 is a direct measure of oxygen saturation in the blood, while VO2max is an indirect measure of aerobic fitness. Higher SpO2 levels indicate better oxygenation, while a higher VO2max indicates better cardiovascular fitness. Both are important indicators of overall health and fitness levels.
