COMPACT 4 AND 5 OXYGEN CONCENTRATORS

QUESTIONS & ANSWERS

Q1: How does an oxygen concentrator work?

A1: An oxygen concentrator, simply put, is an elaborate mechanical filter. Utilizing a few system controls a concentrator cycles room air into and between canisters containing molecular sieve material (sieve beds) to achieve air separation and oxygen production. The end result is therapeutic oxygen delivered to the patient and retained gases purged through the system's exhaust.

Q2: How often should the gross particle filter be cleaned?

A2: At least once a week or as needed

Q3: When should my dealer change the Extended Life Intake Bacteria Filter?

A3: Once a year.

Q4: How often should the Compressor HEPA Filter be changed?

A4: Every five years or 25, 000 hours of operation whichever comes first.

Q5: When should the final bacteria filter be changed?

A5: Every two years.

Q6: What length should the oxygen tubing NOT exceed?

A6: 50 feet

Q7: What is OSD?

A7: Oxygen Sensing Device - measures the concentration of oxygen produced by the concentrator. Bar O2's OSD is based on ultrasonic technology, which measures the speed of sound. The speed of sound gets faster or slower depending on the percent of oxygen in a gas. The microcomputer in the oxygen sensor calculates the oxygen content in a concentrator's flowing gas stream by measuring the oxygen concentration with and against the flow, measuring the temperature.
