Which condition requires immediate PPV via LMA or ET?

The condition that necessitates immediate positive pressure ventilation (PPV) through a laryngeal mask airway (LMA) or endotracheal tube (ET) is gasping. Gasping is considered an ineffective respiratory effort that indicates inadequate ventilation. It often reflects a critical state of oxygenation, where the neonate or patient is unable to effectively exchange gases, leading to an immediate need for intervention to provide adequate ventilation and oxygen delivery.

Providing PPV in the context of gasping is crucial because this action can rapidly help improve the patient's breathing status, restore normal respiratory function, and prevent further deterioration. In emergency scenarios, the priority is to correct any hypoxia resulting from compromised respiratory efforts, and gasping signals that the individual may not be receiving sufficient oxygen on their own. Thus, initiating PPV is a necessary step in managing this condition.
