Explain the devices used for oxygen administration.

1. Nasal Cannula:

• Delivers low to moderate levels of oxygen.
• Consists of two small tubes placed in the nostrils.

1. Oxygen Masks:

• Covers the nose and mouth.
• Provides higher concentrations of oxygen.

1. Venturi Mask:

• Allows precise control of oxygen concentration.
• Adjusts the air entrainment ports to mix oxygen with inhaled air.

1. Non-Rebreather Mask:

• Delivers high concentrations of oxygen.
• Contains a one-way valve to prevent exhaled air from entering the mask.

1. Oxygen Tent:

• Encloses the patient in a plastic tent filled with oxygen.
• Used for infants or patients who need a controlled environment.

1. Transtracheal Oxygen Catheter:

• Directly delivers oxygen into the trachea.
• Requires a surgical procedure for placement.

1. High-Flow Nasal Cannula (HFNC):

• Delivers heated and humidified oxygen at higher flow rates.
• Useful for patients requiring high levels of oxygen.

1. Oxygen Concentrator:

• Extracts oxygen from the air.
• Supplies a continuous flow of oxygen.

1. Liquid Oxygen System:

• Stores oxygen in liquid form.
• Converts to gas before inhalation.

1. Hyperbaric Oxygen Therapy (HBOT):
   • Involves breathing pure oxygen in a pressurized room or chamber.
   • Used for certain medical conditions.
