Nasal Cannula Usage and Care

The video tutorial explains the use of a nasal cannula as a low flow oxygen device, detailing its setup, application, and adjustment for patient comfort and safety. It covers the importance of correct placement to ensure effective oxygen delivery and discusses the use of a humidifier to prevent dryness. The tutorial also highlights the need to prevent pressure ulcers by ensuring the cannula is not too tight.

• 1 to 3 liters

• 6 to 10 liters

• 3 to 6 liters

• 1 to 6 liters

What is the purpose of the 'Christmas tree' adapter in setting up a nasal cannula?

• To measure the oxygen flow

• To secure the cannula to the patient's face

• To connect the cannula to the flow meter

• To humidify the oxygen

How should the prongs of a nasal cannula be oriented when applied to a patient?

• Curved back

• Curved downwards

• Straight

• Curved upwards

What is a potential consequence of tightening the nasal cannula tubing too much?

• Improved patient comfort

• Pressure ulcers

• Increased oxygen delivery

• Reduced oxygen flow

Why is it recommended to use a humidifier with a nasal cannula for flows greater than 3 liters?

• To improve oxygen absorption

• To reduce noise

• To prevent drying of nasal passages

• To increase oxygen concentration
