What is the purpose of applying a pulse oximeter in PACU?

The purpose of applying a pulse oximeter in the PACU is to monitor the patient’s oxygen saturation level. This is critically important following surgery, as anesthesia and the surgical procedure can impact a patient's ability to adequately oxygenate. The pulse oximeter provides a non-invasive and continuous method of measuring the percentage of hemoglobin that is saturated with oxygen, giving healthcare providers immediate feedback on the patient's respiratory function.

Maintaining appropriate oxygen levels is vital to prevent hypoxia, which can lead to various complications. By routinely checking oxygen saturation levels, clinicians can quickly identify any issues, enabling timely interventions if the levels fall below the acceptable range. This monitoring plays an essential role in ensuring patient safety and effective recovery in the postoperative setting.
