Key Features

• Adult-sized anatomical shape
  Designed to comfortably fit over the nose and mouth of an adult, forming a gentle seal for efficient oxygen delivery.

• Soft medical-grade material
  Usually made of clear, flexible PVC to enhance comfort and allow healthcare providers to observe breathing and skin color.

• Elastic head strap
  An adjustable strap keeps the mask securely in place without requiring the patient to hold it.

• Flexible nose clip
  Many masks include a metal or molded clip that can be adjusted to improve the fit and minimize oxygen leakage.

• Standard oxygen tubing
  The mask comes with long, kink-resistant tubing that connects to an oxygen source. Ribbed or star-lumen designs help maintain airflow even if the tube bends.

• Universal connector
  Fits standard oxygen outlets on concentrators, wall ports, and cylinders.

How It Works

Oxygen flows from the source through the tubing and into the mask, where the patient inhales it directly. The mask ensures a higher concentration of oxygen compared to room air and is useful for patients who require controlled oxygen therapy.

Common Uses

• Breathing difficulty due to respiratory illness

• Emergency resuscitation

• Post-surgical recovery

• Chronic lung diseases such as COPD

• Situations where a nasal cannula is insufficient

Types of Adult Oxygen Masks

• Simple oxygen mask – provides moderate oxygen concentrations.

• Non-rebreather mask – delivers high oxygen concentration with one-way valves and reservoir bag.

• Venturi mask – delivers precise oxygen concentration settings.

Key Features

• Soft dual nasal prongs
  Two small curved tips sit inside the nostrils and deliver a steady flow of oxygen without causing significant irritation.

• Flexible, medical-grade tubing
  Made of soft PVC designed to rest comfortably over the ears and under the chin, minimizing pressure and skin irritation.

• Kink-resistant design
  Often features a star-lumen or ribbed structure that prevents the tube from collapsing, ensuring consistent oxygen flow.

• Universal oxygen connector
  The end of the tubing fits standard oxygen outlets on concentrators, cylinders, and wall ports.

• Lightweight and comfortable
  Preferred for patients requiring long-term or continuous oxygen therapy because it allows free movement, speaking, and oral intake.

How It Works

Oxygen flows from the supply source through the tubing and exits through the nasal prongs directly into the nostrils. The patient inhales the enriched air naturally with each breath.

Typical Flow Rates

• Usually used for 1–6 liters per minute

• Provides 24%–44% oxygen concentration, depending on flow and patient breathing

Common Uses

• Long-term oxygen therapy for chronic lung disease (e.g., COPD)

• Mild to moderate respiratory distress

• Recovery after surgery

• Home oxygen therapy

• Emergency and ambulance use

• Situations where a mask is uncomfortable or unnecessary

Benefits

• Allows talking, eating, and drinking

• Less claustrophobic than a mask

• Minimal obstruction to the face

• Suitable for extended use
