The disposable Xhale Assurance Nasal Alar SpO2 Sensor* measures arterial oxygen saturation at the ala, which is an optimal measurement site for difficult-to-measure patients. It produces a strong, consistent signal, even in patients with poor perfusion. Designed for comfort and durability, the sensor is non-adhesive and can be used for up to seven days.
