P2-E7 Portable Oxygen Concentrator
The P2-E7 Oxygen Concentrator by Rhythm Healthcare is prescribed for patients requiring supplemental oxygen. It supplies a high concentration of oxygen (hence the name oxygen concentrator) and is used with a nasal cannula to delivery oxygen from the concentrator to the patient. The P2-E7 is a small and portable device that can be used at home and can be taken with you while performing your daily activities. You can also charge the battery in the car with the included DC power cord which means you don’t always need to be by an electrical outlet. Oxygen users get greater mobility and independence.
Atmospheric air is only about 21% oxygen and mostly nitrogen. Oxygen concentrators remove most of the nitrogen from the air to create a 90%+ oxygen concentration. The P2-E7, along with it’s high-absorption sieve bed, removes even more nitrogen, giving you 93% oxygen concentration! And with 7 different pulse settings in the P2-E7, you get even more.
