A post-op cardiac patient with esophageal monitor. Ventilator settings are APVcmv mode, VT 400 mL, RR 20, PEEP 8 cm H2O, and FiO2 75%. What changes would you do on the ventilator.
What changes would you do on the ventilator given the above graphics:
No changes
Increase PEEP to 10
Increase PEEP to 12
Increase PEEP to 14
You need to keep the expiratory trans-pulmonary pressure at 0-5, therefore we should add extra 6 cm H2O of PEEP at the minimum, this is coming from the esophageal pressure measured at -6.2 during expiration.
