The thought here is that those patients with more edema might benefit more from higher PEEP.Interestingly, in some patients PEEP seems to cause harmful overdistention without eliminating the atelectasis.
Too high a tidal volume or a pressure and we risk various forms of barotrauma and too little of either seems to be associated with atelectasis ,blood shunting and another form of ventilator induced lung damage from forces related to opening and closing of gas exchange units.
With the now commonplace use of low tidal volumes one would expect more micro-atelectasis and it seems reasonable that higher PEEP might be needed to mitigate that tendency.
Obstructive foreign bodies cause atelectasis, drowned lung, and eventually pulmonary abscess.
When a bronchus is completely obstructed by the bulk of the foreign body itself immediate removal is urgently demanded to prevent serious lung changes, resulting from atelectasis and want of drainage.
An atelectasis here exists; the air imprisoned in the lung is soon absorbed, and secretions rapidly accumulate.

The most common adverse reactions in patients treated with OFIRMEV were nausea, vomiting, headache, and insomnia in adult patients and nausea, vomiting, constipation, pruritus, agitation, and atelectasis in pediatric patients.
Formation of atelectasis and inadequate oxygenation with very low tidal volumes may be important factors.
