When is PEEP recommended to be set at 10 cmH₂O?

PEEP, or Positive End-Expiratory Pressure, is a mode of mechanical ventilation aimed at preventing the collapse of alveoli at the end of expiration, which is particularly beneficial in certain clinical conditions. The recommendation to set PEEP at 10 cmH₂O is specifically indicated for adults with cardiogenic pulmonary oedema, as it helps to improve oxygenation and enhance lung mechanics.

In cases of cardiogenic pulmonary oedema, the lungs are filled with excess fluid due to heart failure, making gas exchange inefficient. By applying PEEP, you can increase the functional residual capacity (FRC) of the lungs, reduce the shunting of blood, and improve overall oxygenation by recruiting collapsed or fluid-filled alveoli. This improves ventilation-perfusion matching and helps the patient maintain adequate oxygen levels.

The other options do not align with the standard practices involving PEEP settings. For instance, a blanket approach for all pediatric patients may not apply, as pediatric lung mechanics and capacities differ significantly from adults. Similarly, while patients with moderate asthma may require supportive respiratory interventions, PEEP at this level is not typically indicated unless the patient has complications that warrant it. For patients experiencing shock, the focus may be more on addressing the underlying cause and stabilizing he
