Alar Nasal Pulse Oximetry Sensor: Anesthesia Application

Alar Nasal Pulse Oximetry Sensor works on the most challenging patients!

Anesthesia Advantages

“It works when other sensors fail.” The monitoring site is unaffected by non-invasive blood pressure measurements thus reducing false alarms and giving the anesthesia provider uninterrupted oximeter measurements. The Alar Nasal Pulse Oximetry Sensor can be left on for PACU and SICU providing oximeter measurements for the entire length of stay of the post-surgical patient saving the hospital thousands and enhancing patient comfort.

Reliable accuracy – unaffected by poor peripheral perfusion or low saturations

The Alar Nasal Pulse Oximetry Sensor fits comfortably on the fleshy part of the side of the nose. The site is fed by both the external and internal carotid arteries; the latter also provides blood to the brain. The rich vascular supply to this region provides a strong, reliable signal, even when it is difficult or impossible to get a signal at the fingertips.

Monitoring Site results in faster detection of oxygen saturation changes

Because the Alar Nasal Pulse Oximetry Sensor measures the oxygen saturation from a vessel also supplying blood to the brain, changes have been proven to be detected up to 30 seconds faster than with a finger sensor.

Improved patient comfort

The hands-free Alar Sensor does not impede normal patient functions such as eating, drinking or talking. It is less bothersome and is not likely to become disconnected.

Cost effective and convenient

The single-patient-use Alar Sensor does not use adhesives at the sensor site. The sensor can be removed and reapplied for up to 7 days saving hospitals up to $232 for the SICU patient. Proven accuracy reduces false alarms improving patient safety, patient satisfaction and nurse productivity.

TOF Watch Discontinued! Stimpod NMS 450 available NOW!

The German manufacturer, MIPM – Mammendorfer Institut für Physik und Medizin GmbH has announced that effective June 30, 2016 the TOF Watch, TOF Watch S and TOF Watch SX neuromuscular monitors will no longer be manufactured.  The official announcement of the discontinuance of the TOF Watch is below:

TOF-Watch – objective neuromuscular monitoring
Product cancelation Note
We wish to inform you that the TOF Watch monitors are not produced and sold any more effective July 1st 2016.

Their USA distributor Blue Star Enterprises will continue selling the TOF Watch while supplies last. They will also offer the replacement alternative from Bell Medical and Xavant called the Stimpod NMS 450. The only accelerometer based neuromuscular monitor now available is the Stimpod NMS 450 from Xavant distributed in the USA and Canada by Bell Medical Inc. The Stimpod NMS 450 is a neuromuscular monitor that offers Quantitative TOF Monitoring as endorsed by the Anesthesia Patient Safety Foundation or APSF.

Stimpod NMS 450 Nerve Stimulator and TOF Monitor

Stimpod NMS 450The Stimpod NMS 450 Nerve Stimulator and TOF Monitor includes a Tri-axial accelerometer which provides real time feedback of the strength of contraction of the affected limb (Train Of Four, Double Burst and Post Tetanic Count modes). The strength of each measured contraction is displayed graphically and the relevant ratios are calculated and also displayed.

The fine movement differences that can be detected by utilizing accelerometry offer major advantages over gauging contraction strength visually or tactilely.

Tri-axial accelerometry calculates the movement vector of the contraction in three dimensions. This negates the need for calibration as is the case with one-dimensional accelerometers, and reduces the setup time of the procedure.

Combined Nerve Mapping and Nerve Location

Auto sensing technology provides a solution for simultaneous nerve mapping and nerve location. The Stimpod monitors whether the mapping probe or needle touches the patient and adjusts the current range accordingly, ensuring quick and precise nerve location.

The Stimpod Nerve Mapping Probe was designed to enable transcutaneous nerve mapping at higher currents (to a maximum of 20mA), whilst the tip offers a contact surface small enough to ensure effective discrimination.
