Which Oxygen Delivery System is Right for Me?

Once a physician authorizes oxygen therapy in the home setting based on patient need, it is normally supplied via one of three different sources: oxygen tanks, liquid systems or oxygen concentrators. Compressed oxygen in metal cylinders is convenient for the small volume user. There is little waste and the oxygen can be stored indefinitely. Larger cylinders are heavy and bulky and can be difficult to handle. The volumes are limited and the high pressure hazard is a legitimate safety concern. Oxygen tanks are affordable and widely available and the smaller cylinders sizes are comfortably portable. Frequent deliveries can be a nuisance as well as the occasional tight valve requiring a strong hand. Oxygen tanks are primarily utilized by the mobile patient, and as a backup to a liquid or concentrator suppply system. A pressure reducing valve with a flowmeter is needed to deliver the gas at the prescribed flow. Oxygen flows in the home care environment generally range from 1/2 to 5 liters per minute. Oxygen cylinder safety measures and patient operating instructions should be thoroughly reviewed and confirmed. Find oxygen tank suppliers in your area.
Liquid oxygen systems are ideal for the high volume patient. Since 1 cubic foot of liquid oxygen is the equivalent of 860 cubic feet of oxygen gas, liquid oxygen systems can store a large volume of oxygen gas in a relatively small space. These are low pressure systems generally between 20 to 25 psi and cannot operate ventilators and high pressure equipment. They must be delivered as needed, are large and bulky and present a low temperature skin burn hazard since the liquid oxygen is kept at about -300 degrees Fahrenheit. Maximum flows are limited to 5-8 liters per minute. Small liquid oxygen cylinders hold between 50-100 lbs of liquid. Portable units can weigh anywhere from 5-15lbs. and can be refilled in a few minutes from the system for an 8 hour supply at 2 LPM. Patients should wear protective gloves when refilling. Find liquid oxygen suppliers in your area.
An oxygen concentrator is a machine that takes in room air and separates out the 20% oxygen and accumulates it for delivery to the patient. Oxygen concentrators are becoming increasingly popular as they offer the most cost effective supply systems for continuous, low flow, 1/2-5 LPM oxygen patients. The most common type uses a molecular sieve of sodium and aluminum silicate pellets that absorb nitrogen, carbon dioxide and water vapor. At flows of 1 to 2 LPM, most concentrators will be able to provide between 90 to 95% oxygen purity. There is no waste and no need for frequent deliveries. They are low pressure systems and cannot operate ventilators and high pressure equipment. Backup oxygen tanks are recommended since a power interruption will cause the unit to become inoperable for the duration. Operating costs are minimal, an oxygen concentrator running 24 hours per day will generally increase the monthly electric bill by only 5-10%. The unit will give off some heat and does create an undesirable low level machine noise. Periodic filter changes and pellet cannister replacement are required.
