![]() The size of the cylinder and the oxygen flow rate determine how long the compressed oxygen cylinder will last ( Table 2). Compressed oxygen cylinders require a regulator and flowmeter. Ideally, the patient should have the lightest cylinder possible that provides oxygen for the longest period of time ( Figure 1). Compressed oxygen cylinders come in a wide variety of sizes.There are three types of oxygen delivery systems available for home use ( Table 1) : compressed oxygen cylinders, liquid oxygen systems, and oxygen concentrator systems. Transtracheal oxygen catheters deliver oxygen through a catheter that is percutaneously inserted into the trachea, bypassing anatomic dead space by reducing the flow rate of oxygen.Demand oxygen delivery systems deliver a burst of oxygen during the early phase of inhalation through a nasal cannula.Reservoir nasal cannulas store oxygen in a chamber during the expiratory phase of respiration for delivery during the early phase of inhalation.OCDs reduce the amount of oxygen that the patient uses, enabling the use of a smaller and lighter unit and reducing the overall cost of the therapy. Long-term oxygen therapy is usually administered via an oxygen-conserving device (OCD) (i.e., oxygen concentrator). Oxygen administered directly into the trachea via a tracheostomy tube or transtracheal catheter should be humidified. When a patient has a permanent tracheostomy tube, a T-piece or tracheostomy collar is used for oxygen administration. Short-term oxygen therapy may be administered via a nasal cannula or a simple face mask. Home oxygen therapy may be short-term or long-term for the patient who is hypoxemic, who has respiratory complications, or who is experiencing activity intolerance. Oxygen is a medication used in and out of the hospital setting. ![]() ![]() The goal of oxygen use in a prehospital setting is to treat hypoxemia, but excess oxygen use can cause hyperoxia, causing worse outcomes. Oxygen is a fire hazard because it lowers the temperature at which materials catch fire in the presence of an ignition source, such as a spark or heat from a light source.
