Non-Rebreather Mask (Paediatric)

Purpose & Use

• A paediatric non-rebreather mask is used to deliver high concentrations of oxygen (60–100%) to children and infants experiencing severe hypoxia, respiratory distress, or trauma.

• Designed to prevent exhaled air from mixing with supplied oxygen, ensuring maximum oxygen delivery to the patient.

Target Patient Population

• Sized specifically for neonates, infants, and children.

• Fits appropriately to cover the nose and mouth of smaller patients without excessive dead space.

Structure & Components

• Mask: soft, flexible material to ensure comfort and minimal leakage.

• Reservoir bag: smaller than adult versions, stores oxygen for inhalation.

• One-way valves:

  • Between the mask and reservoir bag to allow inhalation of oxygen only.

  • On exhalation ports to prevent CO₂ rebreathing.

• Elastic or Velcro straps: adjustable to secure mask on a child’s face.

• Oxygen tubing connector: connects to an oxygen source.

Performance & Flow Rate

• Provides high oxygen concentration (up to 100%) when properly fitted.

• Oxygen flow typically 10–15 L/min for older children, and 5–10 L/min for infants depending on size.

• One-way valves prevent rebreathing of CO₂.

Advantages

• Rapidly increases oxygen saturation in paediatric patients.

• Simple and effective high-flow oxygen delivery without intubation.

• Disposable, reducing the risk of cross-contamination.

• Lightweight and easy to apply to small patients.

Usage Guidelines

• Ensure proper fit to minimize leaks.

• Connect to appropriate high-flow oxygen source based on patient size.

• Monitor oxygen saturation, respiratory rate, and comfort continuously.

• Check that the reservoir bag remains partially inflated during inspiration.

• Used as a short-term intervention until more definitive airway support is available if needed.
