Safety information - Warnings and Cautions
DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
Theory of Operation
The EasyPulse POC is intended to provide supplemental oxygen to the ambulatory oxygen patient in the smallest lightest package possible. Utilizing Precision Medical, Inc.'s patented Oxygen Conserving Technology, the EasyPulsePOC is a state of the art device, designed to be versatile and reliable.
This oxygen conserving technology delivers a true "pulse" of oxygen within the first 1/3 of the patient's inspiration and is unique in several additional ways. A true "pulse” is defined by a high peak flow (4 to 10 LPM) for a very short duration of time (0.2 to 0.4 seconds). It also controls the delivered minute volume which remains consistent between 15 and 35 BPM. The total oxygen volume (delivered minute volume) the patient receives is always the same, as the patient's breath rate decreases the pulse volume increases and conversely when breath rate increases.
The EasyPulse POC senses the patient's Inspiratory effort by means of a micro sensor. The sensor signals a micro valve to open for a specific duration based on setting, patient breathe rate and altitude delivering the bolus of oxygen to the patient. This all happens in less than 0.5 seconds. The delivered minute volume is controlled by the setting, the micro valve timing and the patient's breath rate.
Warnings and Cautions
WARNING: Oxygen supplied from this device is for supplemental use and is not intended to be life supporting or life sustaining. This device is not intended for use by patients who would suffer immediate, permanent, or serious health consequences as a result of an interruption in the oxygen supply.
- This device is NOT to be used by patients who breathe through their mouths.
- DO NOT smoke in an area where oxygen is being administered.
- DO NOT use near any type of flame or flammable/explosive substances, vapors or atmosphere.
- DO NOT use oils, greases, lubricants or any combustible materials on or near this product. Wash hands properly prior to usage.
TO AVOID INCREASED RISK OF FIRE
- Keep oxygen equipment away from open flames. Use and store the POC at least five (5) feet away from equipment such as furnaces, water heaters, and stoves that may contain open flames.
- Keep equipment in a well-ventilated area at all times.
- High concentrations of oxygen can cause rapid burning of other substances.
- DO NOT place blankets, draperies, or other fabrics over equipment.
- DO NOT use if dirt or contaminants are present on or around fill connectors on the POC.
- NO OXYGEN is delivered when the Pulse Selector is at the "Off" Setting.

Checking the Oxygen Purity
To Put the EasyPulse POC in Test Mode
*It is very important to remove any external power source and allow the device to sit for at least 15 seconds before attempting to put in to the test mode.
*Do not block the outlet while in the test mode. Damage to the device may occur and is not covered under warranty.
- Attach the EasyPulse POC to the oxygen purity test device
- Remove all external power sources
- Turn device off for 15 seconds
- Then, like a combination lock, turn dial to: 5, then 1, then 3, then off.
- Turn device to any flow setting. Device will continuously pulse.
- The alarm LED on the front will blink yellow and red while in test mode. (Steps 3 & 4 must be completed within 8 seconds)
- Attach any external power source if needed.
- In this mode, you can go to any flow setting and test oxygen purity. The device will pulse as if it was attached to a simulator breathing 20 breaths per minute.
- To return device to normal function, turn dial to off position. Once the device is turned to the off position, you will need to go through the above steps to get the device back into the test mode.
