Oxygen Delivery Devices
Low-Flow Oxygen Delivery
1. Nasal cannula (nasal prongs)
2. Simple face mask
3. Non re-breather mask
It consists of a face mask connected to a reservoir bag that's filled with a high concentration of oxygen. The reservoir bag is connected to an oxygen tank.
The mask has a one-way valve system, generally only used for short-term increases in oxygenation.
Moderate-Flow Oxygen Delivery
4. Partial non-rebreather mask
5. Hudson mask (rarely used)
High flow oxygen delivery
6. High Flow Nasal prongs
7. High flow venturi mask
Delivers 24-60% oxygen
Different colours deliver different flow rates and oxygen percentage.
Flow rate along with percentage of oxygen delivered varies with colour.
Colour types are;
BLUE = 2-4L/min = 24% O2
WHITE = 4-6L/min = 28% O2
YELLOW = 8-10L/min = 35% O2
RED = 10-12L/min = 40% O2
GREEN = 12-15L/min = 60% O2
Venturi masks are often used in COPD, where it is important not to over-oxygenate the patient.
7. Face tent
Face tent is shield-like device that fits under the patient's chin and encircles the face.
8. Oxygen hood
Oxygen hood is used for babies.
