Mr. Jones is 68-year-old male.  He was admitted to the step down unit two days ago due to altered mental status (AMS) and a urinary tract infection (UTI).  He is currently on a 55% venti mask and is lethargic, with labored and shallow breathing.  His current labs and vital signs are as followed:   Vital Signs: HR 125 RR 28 BP 64/47 Sa02 90%   BBS: decreased aeration X-ray: no acute changes   ABG: pH 7.02 PCO2 88 PO2 52 HCO3 12 S02 88%   What mode of ventilation would you recommend for Mr. Jones?
