About The Safety Pop Off Valve (Spov)

The pop-off valve is a life-critical piece of the anesthesia machine. A pop-off valve that remains in the closed position allows pressure to build up in the patient's lungs and this compromises the health and well-being of anesthetized animals.

The Safety Pop-Off Valve (SPOV), or Safety Pressure Relief Valve, is one of the most important improvements in anesthesia machine safety.

Use of Oxygen Concentrators In Veterinary Anesthesia

Pureline Anesthesia Products

This white paper sets forth to educate readers about oxygen concentrators, how they were developed and how they can now be used for veterinary medicine. It also seeks to explain the cost advantages (ROI) of using oxygen concentrators for veterinary medicine while simultaneously addressing safety concerns for both patients and the veterinarians.

The Challenges of Compressed Oxygen Cylinders

Use of Oxygen Concentrators in Veterinary Anesthesia

While the necessity for oxygen in veterinary anesthesia promises to be a consistent one, the delivery is not limited to the use of large, bulky, and expensive oxygen tanks. Used in both human and veterinary anesthesia for over 40 years, oxygen concentrators have proven themselves to be a safe, efficient, reliable, cost-effective, portable, and more flexible alternative to traditional compressed oxygen cylinders.

The Pureline® Solution

Led by President and CEO Brian Lawson, Supera Anesthesia Innovations (formerly LEI Medical) has firmly planted itself at the forefront of innovation with the introduction of the Pureline series of oxygen concentrators. With the Pureline brand, Supera has perfected the oxygen concentrator technology, offering seamless integration with current equipment, the highest quality components, added safety features, and a return on investment (ROI) as low as one year. Supera offers an industry best 3 year warranty on its Pureline oxygen concentrators and a full 10 year warranty on their anesthesia machines.

While many oxygen concentrators intended for veterinary use are merely an "oxygen therapy" version of concentrators designed for use with human patients, Pureline concentrators are purpose-built for use with pressurized veterinary anesthesia equipment, which allows you to provide the best and most reliable care possible to your patients.
