Which is the correct placement of simple oxygen mask in paediatrics?

Appeared in: NORCET 2 -2021 (Shift-2)

Explanation

The correct placement for an oxygen mask is to cover both the nose and mouth completely.
This ensures that the patient receives the intended concentration of oxygen regardless of whether they are breathing through their nose or mouth.
A snug fit from the bridge of the nose to the chin is necessary to create an effective seal and prevent oxygen from leaking, which would reduce the therapy's effectiveness and could irritate the eyes.
Infants are often obligate nose breathers, making it critical for the mask to cover the nose to ensure any oxygen is inhaled.

Option A: Image A shows the mask placed too high, covering the eyes. This is incorrect and dangerous.
Option C: Image C shows the mask covering only the mouth, leaving the nose exposed. This is ineffective.
Option D: Image D shows the mask on the neck, completely missing the airway. This provides no oxygen therapy.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Application of Oxygen Therapy in Pediatrics as background academic context rather than a clinical decision trigger.
Proper mask fit is a fundamental nursing skill critical for patient safety and effective treatment. An ill-fitting mask can lead to hypoxemia despite the administration of oxygen.
Nurses must perform regular skin assessments for patients on continuous oxygen therapy via mask to prevent pressure injuries, especially in children with delicate skin.
What if the child is claustrophobic and resists the mask? The nurse should first try to calm and reassure the child. If that fails, an alternative delivery device like a nasal cannula or an oxygen hood (for infants) should be considered in consultation with the provider.

How to Approach the Question

First, identify the core question: It asks for the 'correct placement' of a pediatric oxygen mask.
Analyze the function of an oxygen mask: Its purpose is to deliver oxygen to be inhaled through the airway (nose and mouth).
Evaluate each image based on this function. Ask yourself for each option: 'Does this placement allow the child to breathe in the oxygen effectively?'
Image A: No, it covers the eyes and would leak.
Image B: Yes, it covers both the nose and mouth.
Image C: No, it misses the nose, which is a primary breathing passage.
