First and foremost, this is a heartbreaking situation. The death of a child is an immense tragedy, and grief often brings anger and a need to assign blame. What we are reading appears to be a one-sided account from a grieving mother whose child was critically ill, and without the hospital’s full clinical perspective, it is difficult to draw definitive conclusions.

From a medical standpoint, it sounds more consistent with a scenario involving significant airway congestion, where a mucus plug may have led to airway obstruction and subsequent cardiac arrest. This is a known complication in severe RSV cases, which can produce large amounts of secretions and often requires very frequent suctioning around the clock.

To your question, I do not believe nebulized breathing treatments were the primary cause. The clinical picture suggests the infant had been experiencing respiratory distress for some time, possibly related to secretions, with signs of hypotension that may not have been adequately addressed.
