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%.
A normal reading for pulse rate (PRBPM) typically ranges from 60 to 100 beats per minute for adults. The normal range for oxygen saturation (SpO2) is generally between 95% and 100%. Values outside these ranges may indicate potential health issues that require further evaluation.
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.

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.
Decreasing spo2 signifies - decreased efficiency of lungs to absorb enough oxygen, required to have normal gaseous exchange.

SpO2 stands for peripheral capillary oxygen saturation, which is a measure of the amount of oxygen-saturated hemoglobin in the blood. It is typically expressed as a percentage, indicating how effectively oxygen is being transported throughout the body. SpO2 is commonly measured using a pulse oximeter, a non-invasive device that clips onto a finger or earlobe. Normal SpO2 levels typically range from 95% to 100%.
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 peripheral capillary oxygen saturation, is a measure of the amount of oxygen bound to hemoglobin in the blood. It is expressed as a percentage and is an important vital sign indicating how effectively oxygen is being transported throughout the body. Normal SPO2 levels typically range from 95% to 100%, and values below this range may indicate respiratory or circulatory issues. Monitoring SPO2 is crucial in clinical settings, especially for patients with respiratory conditions or those undergoing anesthesia.
