O2 delivery

Nasal Cannula

A low flow oxygen delivery device that allows patients to eat and drink, delivers 1-6 L/min of oxygen at 24-44% concentration.

What is the flow rate and concentration range for a Nasal Cannula?

1-6 L/min delivering 24-44% oxygen.

O2 conserving cannula

An oxygen delivery device for long-term use, featuring a built-in reservoir that allows for 30-50% oxygen at a lower flow.

What is a disadvantage of using an O2 conserving cannula?

It is expensive and hard to clean.

Simple face mask

An oxygen delivery device for quick delivery, requiring a minimum of 5L/min, with a concentration range of 35-50%.

What is the minimum flow rate needed for a Simple face mask?

A minimum of 5 L/min is necessary.

Partial rebreathing mask

A low flow oxygen delivery device that provides 40-60% oxygen at 6-10 L/min and allows expired air to flow back.

What flow rate of oxygen does a Partial rebreathing mask deliver?

6-10 L/min providing 40-60% oxygen.

Non-rebreathing mask

An oxygen delivery device that provides high concentration (60-90%) oxygen with a snug fit and does not allow expired air to flow back.

What is a key feature of the Non-rebreathing mask?

The bag cannot deflate, ensuring high concentration oxygen delivery.

Venturi mask

An oxygen delivery device that provides precise high flow rates of oxygen, suitable for COPD patients, ranging from 24% to 50%.

What is an advantage of the Venturi mask for COPD patients?

It gives low constant rates of oxygen and is not affected by room air or breathing patterns.
