===Acute respiratory distress syndrome===
Protective lung ventilation strategies apply. V<sub>T</sub> 6 to 8&nbsp;ml/kg or as low as 5&nbsp;ml/kg in severe cases. Permissive hypercapnia can be employed in an attempt to minimize aggressive ventilation leading to lung injury. Higher PEEPs are often required however not all ARDS patients require the same PEEP levels.{{clarify|Why not?|date=January 2022}} Patient should be started on 6&nbsp;ml/kg and PEEP increased until plateau pressure is 30&nbsp;cm&nbsp;H<sub>2</sub>0 in most severe cases.{{citation needed|date=January 2022}}{{clarify|Why?|date=January 2022}}
