The chest X-ray for an 80 kg ( 176 lb) pt receiving MV support shows bilateral, patch
infiltrates in the basilar area of the lungs. Auscultation reveals bibasilar crackles.
Ventilator settings for the patient are as follows: SIMV mandatory rate 14/min TV 550
ml, FiO2 .40, PEEP 5. Arterial blood gases have the following results pH 7.33, PaCO2
47, PaO2 75, HCO3- 24. The RT should recommend
