List Of High Flow Oxygen Devices

Oxygen delivery devices range from very simple and inexpensive designs to more complex and costly.

List of high flow oxygen devices.

2 low flow systems provide oxygen at flow rates that are lower than patients inspiratory demands. The system provides a high flow of heated humidified air to the patient via the nasal cannula. The flow rate can be set on the wall tap. Learn vocabulary terms and more with flashcards games and other study tools.

Remember this is not a hard and fast 6 liters per minute rule it is relative to the patient s own minute ventilation which will change based on their physiologic status activity and from person to person. The percentage of oxygen you are receiving from a given flow rate is not a precise science but there are some guidelines you can rely on for a relatively accurate estimate. The indications advantages and disadvantages of each device and delivery system are presented. The humidifier should always be placed at a level below the patient s head.

The natural air we breathe contains 21 oxygen 21. Thus when the total ventilation exceeds the capacity of the oxygen reservoir room air is entrained. Conversely high flow systems are going to deliver oxygen at a rate higher than the patient s minute ventilation. Oxygen therapy can be delivered using a low flow or high flow system.

Delivery devices work with different flow rates. Start studying 101 high flow oxygen devices. Oxygen use has extended from inpatient to outpatient settings for patients with chronic pulmonary diseases and complications of hypoxaemia. The percentage of oxygen inspired depends on the flow rate and the delivery device.

All high flow systems require humidification. Low flow oxygen devices nasal cannula simple face mask partial rebreather mask 11. High flow devices systems trans tracheal cathetres venturi mask aerosol mask tracheostomy collars t piece non rebreathing mask with reservoir and one way valve high humidity face tents 12. They include nasal cannulae.

Flow rate 1 4l min 4l will dry the nose 2l is more comfortable. High flow oxygen therapy systems used in the hospital environment usually consist of a blender used with or without oxygen from a wall outlet humidifier heated tubing and nasal cannula. It varies from 0 15l per minute. Comparing the fraction of inspired oxygen fio2 in the air to a portable oxygen device is expressed as a percentage.

Oxygen administration can be delivered via low flow or high flow systems with humidity or not and with a reservoir or not. The type of humidification device selected will depend on the oxygen delivery system in use and the patient s requirements.
