Oxygen Delivery Systems

This set of flashcards covers key concepts and definitions related to oxygen delivery systems, including low and high flow rate systems.

Low Flow Rate Systems

Oxygen delivery systems that do not provide enough flow of oxygen to meet total oxygen need; part of tidal volume is supplied by room air.

What are the low flow systems

NC ,simple face mask , partial rebreather & non rebreather

Nasal Cannula

A low flow rate device delivering 1-6 L/min of oxygen, providing 24-44% oxygen, often used for chronic lung disease patients.

Simple Face Mask

Delivers 40-60% oxygen at minimum flow rates of 5-10 L/min, used for short-term therapy or emergencies.

Partial Rebreather Mask

Delivers 60-75% oxygen with flow rates of 8-10 L/min; allows the client to rebreath part of their exhaled air.

High Flow Rate Systems

Oxygen delivery systems that provide sufficient flow to meet entire oxygen needs regardless of breathing patterns.

What are the high flow systems?

Venturi , face tent , tracheostomy collar , T-piece , aerosol mask,HFNC

Venturi Mask

Delivers the most accurate oxygen concentration (24%-60%) using adaptors; best for clients with chronic lung disease.

Face Tent

A high flow oxygen delivery device that fits over the chin and face, used for facial trauma or burns.

Aerosol Mask

Used when high humidity is needed, especially after extubation or upper airway surgery.

Tracheostomy Collar

Used to deliver high humidity and oxygen to patients with tracheostomies.

Non-rebreather Mask

Delivers 90% oxygen at flow rates of 10-15 L/min, used for patients in unstable respiratory status.
