Why is using an adhesive sensor recommended for pulse oximetry?

Using an adhesive sensor for pulse oximetry is recommended primarily because it can be placed on various parts of the body. This flexibility is crucial, especially in clinical settings or situations where traditional placement on the fingertip may not be feasible. For instance, if a patient has peripheral vascular disease, swelling, or a cast on a limb, using an adhesive sensor allows for accurate pulse oximetry readings from alternative sites like the earlobe or forehead.

This advantage enhances the monitoring capabilities for a diverse range of patients, making it particularly valuable in both emergency situations and routine assessments. Furthermore, this adaptability can be essential in pediatric care, where smaller and more sensitive attachment areas are often necessary.

The other options, while relevant to pulse oximetry, do not encapsulate the unique advantage of adhesive sensors to the same extent. For example, while some adhesive sensors may be suitable for clients with compromised circulation, the primary benefit remains their versatile placement capability.
