Flashcards
Nasal Cannula
Nasal Cannula
A device used for low-flow, low-percentage supplemental oxygen, delivering between 25% and 45% oxygen at 1-6 L/min.
Simple Face Mask
Simple Face Mask
Lateral perforations permit exhaled COâ‚‚ to escape and delivers 35%-60% oxygen with a flow rate of 6-10 L/min.
Nonrebreather Mask
Nonrebreather Mask
Mask using a reservoir bag to deliver up to 100% oxygen with a flow rate of 10-15 L/min. One-way flaps prevent room air entrainment and COâ‚‚ retention.

Study Notes
- Oxygen delivery equipment provides supplemental oxygen to patients
Nasal Cannula
- Appropriate for low-flow, low-percentage oxygen supplementation
- Delivers 25%-45% oxygen
- Flow rate is 1-6 L/min
- Patients can eat, drink, and talk while using
- Extended use can be very drying, and should therefore be used with a humidifier
Simple Face Mask
- Appropriate when a higher percentage of supplemental oxygen is needed
- Delivers 35%-60% oxygen
- Flow rate of 6-10 L/min
- Lateral perforations allow exhaled COâ‚‚ to escape
- Humidification is permitted
Nonrebreather Mask
- Appropriate for high percentage FiOâ‚‚ delivery
- Delivers up to 100% oxygen
- Flow rate of 10-15 L/min
- A reservoir bag is incorporated
- One-way flaps prevent room air entrainment during inspiration
- One-way flaps prevent retention of exhaled gases (COâ‚‚) during expiration
- Both flaps removed results in lower (80%-85%) FiOâ‚‚
- One flap removed results in higher (85%-90%) FiOâ‚‚
- Both flaps in place results in maximum (95%-100%) FiOâ‚‚
Venturi Mask (Venti-mask)
- Appropriate for precise titration of percentage of oxygen
- Delivers 24%-60% oxygen
- Flow rate of 4-8 L/min
- Either a graduated dial set to desired FiOâ‚‚ or colored adapters are used to deliver desired FiOâ‚‚
- Delivers 24% FiOâ‚‚ with a blue adapter
- Delivers 28% FiOâ‚‚ with a white adapter
- Delivers 31% FiOâ‚‚ with an orange adapter
- Delivers 35% FiOâ‚‚ with a yellow adapter
- Delivers 40% FiOâ‚‚ with a red adapter
- Delivers 60% FiOâ‚‚ with a green adapter
