The Only Certifiable Pneumatic Pulse-Flow Oxygen Conserver for the Aviation Market

At an AirVenture Oshkosh press conference, Precise Flight Inc. introduced PreciseFlow, an oxygen conserver engineered to deliver the most simplistic and intuitive technology on the market for average oxygen use. Strictly mechanical, PreciseFlow is designed to deliver oxygen in the pulsed manner to meet FAA requirements for demand flow that adapts to individual physiological needs, as opposed to the more conventional continuous-flow systems. This "intelligence," coupled with the fact that it is not battery- or software-dependent, allows PreciseFlow to be the only certifiable pulsed cannula device on the market.

Said Scott Philiben, Precise Flight's vice-president of sales & business development, "The real genius of this system is its basic mechanical simplicity. No batteries to be replaced. No software to crash on you at 18,000 feet. We designed PreciseFlow as a system that does not infringe its "bells and whistles" on pilot workload, but operates silently, safely and efficiently. Its greatest benefit is in reducing the quantity of oxygen required, allowing pilots to utilize the smallest and lightest oxygen supply to meet their individual needs. The pilot simply dials in an altitude to the nearest 2,000 feet and a pulse of oxygen is triggered at the beginning of each breath. Since the output flow is variable, with a large amount delivered in the critical phase of inhalation, it allows the user to remain fully oxygenated while conserving the aircraft oxygen supply. Its conservation rate, versus continuous systems, is roughly triple at the 16,000 to 18,000 feet altitude range and, at lower altitudes, at least double. PreciseFlow's efficiency actually improves with altitude."

Continued Mr. Philiben, "In a recent STC flight test for our SpeedBrake™ System, I took this stomach-churning opportunity to test PreciseFlow in a situation and at an altitude most pilots would not associate with oxygen use. During the stall series of the test program, I typically start to feel a bit nauseous and get a rather large headache. However, with PreciseFlow supplementing my oxygen supply, I came out of the test program feeling alert, steady in the knees, and ready for lunch - an event I normally would have put off for a few hours after touching down."

Said former Marine Corps pilot, Jerry Pierce, who also tested PreciseFlow in his Bonanza D35 at 12,000 feet, "I found the system to be easy to use and intuitively designed. It was the closest I've come to breathing naturally and, versus the continuous-flow system I normally use, it was much less drying on my nasal cavities. I'd say its biggest and most pleasant surprise was that I saved more than twice the oxygen capacity I typically would have, considering my altitude and

length of flight, and actually walked off the strip feeling more alert. Precise Flight builds good stuff. With PreciseFlow, they've done it once again." Designed to integrate with Precise Flight's popular Nelson Oxygen System, PreciseFlow is a lightweight fluidic device that mounts between the oxygen tank regulator and breathing cannula to deliver oxygen on demand. Precise Flight will demonstrate PreciseFlow at Booths 2139 and 2140 at EAA AirVenture Oshkosh 2003.
