Oxygen Delivery Equipment

Question 1

Nasal Cannula

Answer 1

• Indicated for low-flow, low-percentage supplemental oxygen
• Flow rate of 1 - 6 L/min
• Delivers 25%-45% oxygen
• Extended use can be very drying; use with a humidifier

Question 2

Simple Face Mask

Answer 2

• Indicated for higher percentage supplemental oxygen
• Flow rate of 6 - 10 L/min
• Delivers 35%-60% oxygen
• Lateral perforations permit exhaled CO2 to escape
• Permits humidification

Question 3

Non-rebreather Mask

Answer 3

• Indicated for high percentage FiO2
• Incorporates use of reservoir bag
• Flow rate of 10 - 15 L/min
• Delivers up to 100% oxygen
• One-way flaps prevents entrainment of room air during inspiration and retention of exhaled gases (namely CO2) during expiration

Question 4

Venturi Mask (venti-mask)

Answer 4

• Indicated for precise titration of percentage of oxygen
• Flow rate of 4-8 L/min
• Delivers 24%-60% oxygen
• Uses either a graduated dial set to desired FiO2 or colored adapters selected to deliver desired FiO2

Question 5

Bag-Valve-Mask (BVM)

Answer 5

• Indicated for manual ventilation of Pt who has no or ineffective respirations
• Can deliver 100% oxygen when connected to oxygen source
• Appropriate mask size and fit are essential to create a good seal and prevent injury
• To create seal, hold mask with thumb and index finger, grasp underneath ridge of jaw with remaining three fingers

Question 6

Humidified Systems

Answer 6

• Indicated for Pt requiring long-term oxygen therapy to prevent drying of mucous membranes
• Setup may vary between brands. Fill canister with sterile water to recommended level, attach to oxygen source, and attach mask or cannula to humidifier
• Adjust flow rate

Question 7

Transtracheal Oxygenation

Answer 7

• Indicated for Pts with a tracheostomy who require long-term oxygen therapy and/or intermittent
• Ensure proper placement (over stoma, tracheal tube)
• Assess for and clear secretions as needed
