Case #4Following an automobile accident, a 19 year old male is admitted to the hospital. He has sustained multiple burns, severe pulmonary contusions, and has aspirated. He is admitted to the ICU, intubated and placed on a ventilator with initial settings ofA/C 500 x 16 1.0 +10 PEEP. A PAC is inserted and ABG’sare drawn after 30 minutes of mechanical ventilation. CXR reveals correct placement of the ETT andPAC the presence of bilateral infiltrates.pH = 7.53Hgb = 14 gmsPaCO2 = 35 mmHgPvO2 = 28 mmHgPaO2 = 33 mmHgSvO2 = 58 mmHgHCO3 = 26 mEq/LSaO2 = 78%PAC measurements reveal the following values:CVP = 12 mmHgBP = 140/80 mmHgPAP = 50/25 mmHgHR = 110 beats/minPCWP = 6 mmHgCO = 6.0 L/minPart 3: What is the arterial- venous oxygen content (Ca-vO2) difference for this patient?Part 4: Calculate the patient’s extraction ratio.

Scenario 1: Mr. Pickwick has obstructive sleep apnea, and the doctor has ordered him to be placed on BiPAP at the following settings: mode, S/T; rate, 12 breaths/minute; IPAP = 12 cm H2O; EPAP = 6 cm H2O. You enter his room, identify yourself, and explain everything to him. You also perform a complete assessment. After applying BiPAP, you note a drop in blood pressure and oxygen saturation.
1) What would you recommend to Mr. Pickwick for infection control in the home?
