Critical Care Products - The Nasal Alar SpO2 Sensor
Please view our main critical care products in aid of patient safety - The Nasal ALAR SpO2 Pulse Oximetry Sensor. The Alar sensor provides reliable and accurate monitoring in testing conditions and is especially designed to identify a SATS reading in poorly perfused patients recovering in the ICU. Moreover, when a signal is difficult to obtain via a finger sensor on a peripherally-shutdown patient, the Nasal Alar sensor should be applied.
The nasal ala, the fleshy part of the nose adjacent to the opening of the nares (nostril), is a region rich in vasculature that offers a unique monitoring site for pulse oximetry. This site is fed by both the external and internal carotid arteries. The internal carotid provides blood to the brain, and this multi-directional arterial supply provides strong, reliable photoplethysmography signals that are rapidly responsive to changes in the patient’s arterial oxygen saturation. Unlike the extremities, this measurement site is less susceptible to patient movement and loss of signal due to variations in peripheral perfusion. And it is easily accessed by an anesthesiologist during surgery.
Placement of the Nasal Alar SpO2 Sensor is simple, fitting comfortably on the nasal ala. Since secure sensor placement does not depend upon adhesive attachment, the sensor is easily removed and reapplied as necessary for use throughout the length of the patient’s hospital stay.
