Oxygen: delivery devices
- Oxygen therapy.
- Nasal cannulae.
- Hudson mask (rarely used)
- Venturi mask.
- Non-rebreather mask.
- Non-invasive ventilation (CPAP/BiPAP): click here for how to start patients on NIV.
- Invasive ventilation.
What are the 2 main oxygen delivery systems?
Most of these batteries can be recharged approximately 300 times without significant degradation. Generally, there are two types of oxygen delivery in oxygen concentrators: continuous flow dose delivery and pulse mode delivery.
What are the oxygen delivery systems?
An oxygen delivery system is a device used to administer, regulate, and supplement oxygen to a subject to increase the arterial oxygenation. The final concentration of oxygen delivered depends on the ventilatory demands of the patient, the size of the oxygen reservoir, and the rate at which the reservoir is filled.
What is the most accurate oxygen delivery system?
A large nasal catheter was capable of delivering the highest inspired oxygen fraction, whereas the Venturi mask delivered the most precise inspired oxygen fraction.
What are the methods of oxygen administration?
Low flow delivery method
- Simple face mask.
- Non re-breather face mask (mask with oxygen reservoir bag and one-way valves which aims to prevent/reduce room air entrainment)
- Nasal prongs (low flow)
- Tracheostomy mask.
- Tracheostomy HME connector.
- Isolette – neonates (usually for use in the Neonatal Intensive Care Unit only)
What are the types of oxygen administration?
These include:
- oxygen gas.
- liquid oxygen.
- oxygen concentrators.
- hyperbaric oxygen therapy.
What are high flow oxygen delivery systems?
HFO consists of a heated, humidified high-flow nasal cannula (HFNC) that can deliver up to 100% heated and humidified oxygen at a maximum flow of 60 LPM via nasal prongs or cannula. An air/oxygen blender can provide precise oxygen delivery independent of the patient’s inspiratory flow demands.
What is oxygen administration method?
Methods of oxygen administration: • Nasal cannula (prongs): It is a disposable, plastic devise with two protruding prongs for insertion into the nostrils, connected to an oxygen source. Used for low-medium concentrations of Oxygen (24-44%). Nasal cannula (prongs):
Which is better oxygen mask or nasal cannula?
Average SpO2 with mask on was 98% (range 96.1-99.9%), with mask off 95% (range 89.8-98.8%) and with cannula 97% (range 90.8-99.3%). We conclude that nasal cannulae are more likely to remain in position than face masks and maintain an adequate saturation in most patients.
What is the difference between oxygen mask and nasal cannula?
A nasal cannula consists of a flexible tube that is placed under the nose. The tube includes two prongs that go inside the nostrils. A face mask covers the nose and mouth. Both methods of delivery attach to oxygen sources, which come in a variety of sizes.
What is the most common method of oxygen administration?
The most common delivery device for oxygen therapy is a nasal cannula. This device is usually well tolerated by patients and delivers oxygen at prescribed levels.
Which oxygen delivery system delivers the highest concentration of oxygen?
nasal cannula
The nasal cannula is most appropriate for patients experiencing minimal respiratory distress. Like the nasal cannula, the face mask mixes oxygen with room air, but it can provide higher oxygen concentrations (35% to 60%) and higher flow rates (5 to 10 liters/minute).
What is an oxygen delivery system?
“Oxygen delivery system is a device which is used to administer, regulate and supplement oxygen to a subject to increase the arterial oxygenation”
What are the different types of oxygen devices?
This article presents an overview of oxygen devices (oxygen concentrators, compressed gas cylinders and liquid oxygen) and delivery systems (high- and low-flow).

What is the air entrainment in a high flow gas delivery system?
Rightward shift facilitates unloading of O2 a 40% air entrainment — 10L/min O2 flow will produce a total gas flow of approximately 40L/min 28% air entrainment –4 L/min O2 flow will produce a total gas flow of approximately 44 L/min. Page * High flow gas delivery systems supply all the gas the patient needs.
