• Different colours deliver different rates
• Flow rate: Varies with colour. The correct flow rate to use with each colour it is shown on mask, along with the percentage of oxygen delivered

Types:

• 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.
