What should you do when the pulse oximeter alarms?

When the pulse oximeter alarms, one effective response is to palpate the carotid pulse. This action serves to verify whether the patient has an adequate pulse and to check the overall circulatory status. The presence of a pulse will help determine if the alarm represents a false reading, which can occur due to factors such as poor sensor placement, movement, or external interference, such as nail polish on fingers. Palpating the carotid pulse provides an immediate assessment of the patient’s hemodynamic stability and guides further response.

Monitoring pulse oximetry is critical, especially in patients with respiratory issues or those requiring supplemental oxygen. A pulse oximeter alarm may indicate either low oxygen saturation levels or technical issues with the device itself. Hence, confirming the patient's actual pulse can help healthcare providers decide on subsequent actions, such as repositioning the patient or troubleshooting the device.

While other options, such as replacing the sensor, calling for the doctor, or adjusting the patient's position, can be part of the management process, verification of the patient's vital signs through palpation ensures that the immediate care is appropriate and responsive to the actual condition of the patient. It establishes a foundational assessment before taking further steps.
