The Philips Nasal Alar FAST SpO2 Sensor ensures dependable monitoring of oxygen saturation at the nasal ala, where a robust blood supply from the carotid arteries is maintained. This location generates a strong, consistent signal and is less susceptible to vascular constriction compared to extremities,¹ providing accurate and reliable signals, even in challenging conditions involving low perfusion and centralization of blood flow.² Designed for comfort and durability, the sensor is non-adhesive and can be used on one patient for up to seven days across multiple care areas.

Preferred placement for low perfusion
Reliable and comfortable
When compared to forehead sensors, the Nasal Alar SpO₂ Sensor showed lower occurrence of pressure injuries over a period of 5 days of sensor use.³ The alar sensor doesn’t require headbands or adhesive, exposing the patient to minimal heat and pressure, and allowing patients' hands to be sensor-free.

Low perfusion solution
The nasal ala provides reliable measurement
The nasal ala consistently maintains a good blood supply from the internal and external carotid arteries, producing a strong, steady signal and is less prone to vasal constriction than the extremities. It provides reliable results even during critical states of low perfusion and blood flow centralization.
