Oxygen Therapy Modes and Safety Tips


Oxygen comes in gas or liquid form. Oxygen systems may be large and stationary for home use, or small and portable.

Types of oxygen therapy delivery systems include:

  • Compressed gas: A large, metal cylinder stores 100% oxygen as a gas under pressure. The cylinder has a regulator to control the flow of oxygen. A gauge shows the tank’s oxygen levels. When the tank is empty, an oxygen supplier replaces it. You should always have extra oxygen tanks on hand.

  • Liquid oxygen: A thermos-like container stores pure oxygen as a very cold liquid. When you release the oxygen, the liquid converts to a gas that you breathe in. The smaller container makes it portable for use outside the home.

  • Oxygen concentrators: This electric or battery-powered device pulls air from the room.


Step 1: Check Your Supply

  • Check the oxygen gauge on the tank to be sure you have enough

  • Check the water level if you have a humidifier bottle. When the level is at or below half full, refill it with sterile or distilled water
