During a pulse oximetry check, what is an important threshold the PCT should be aware of?

The threshold of 95% for most patients during a pulse oximetry check is critical because it indicates a healthy level of oxygen saturation (SpO2) in the blood for the majority of the population. A reading at or above this level suggests that the body is adequately oxygenated, which is essential for the proper functioning of organs and tissues.

When oxygen saturation falls below 95%, patients may be at risk for hypoxemia, which can lead to various complications. Therefore, monitoring for values significantly below this threshold allows healthcare providers, including Patient Care Technicians, to take appropriate actions, such as notifying a nurse or doctor or administering supplemental oxygen if needed.

While there are different considerations for under specific conditions—like lower thresholds for at-risk populations—95% serves as a general standard for evaluating the oxygen status of most patients. An understanding of this threshold is vital in clinical practice, especially when assessing respiratory status and ensuring patient safety.
