Portable systems range in weight from 6 to 15 pounds. Wheeled transport carts are available for patients who are unable to carry this amount of weight. Oxygen requirements increase planning requirements. This may require cylinder duration calculations. This will ensure the oxygen supply remains adequate for the planned activity.
Most portable systems can supply two to eight hours of oxygen, depending upon which system is used.
Long distance travel requires the oxygen-dependent patient to acquire refill suppliers along their route of travel. This planning requires advanced contact with travel vendors such as airlines and bus companies. Patients utilizing portable liquid oxygen systems must consider certain safety factors. The patient must keep the unit in an upright position and it should not be stored in the trunk of an automobile. Windows should be opened slightly for ventilation, even in winter.
