6LPM of O2, IVF commenced, Stat dose of Prednisone administered, Chest X-ray shows hyperinflation of both lung

fields. She was admitted to ICU due to her deteriorating respiratory function with a diagnosis of acute exacerbation

of asthma.

QUESTION:

2B . Apply and titrate oxygen

– What oxygen delivery device will you use?

Answer 1

In this case, a noninvasive positive pressure ventilation ( CPAP or BiPAP) is suitable to deliver the required oxygen to the child. It helps to improve the blood oxygen level . Besides this, It is important to monitor the oxygen level and titrate the oxygen accordingly. Repeating ABG at a frequent intervals helps to decide the suitalble method of oxygen administration. If the condition worsens, mechanical ventilation measures may require to improve the patient's condition.
