Web• PEEP: for most patients, start at 5-8 cmH20. Since this patient has severe hypoxemia, it might be necessary to start at a PEEP of 10-12. A common down side of higher PEEP is increased intrathoracic pressure, decreased venous return, and hypotension. • Approximately 30 min after the patient is intubated, get an ABG. This is WebApr 8, 2014 · First, increased PEEP causes overdistention of normal alveoli in regions not affected by the focal process. This causes an increase in capillary resistance in those …
