A term neonate who was intubated due to low APGAR scores and the presence of RDS, has been mechanically ventilated for the past 2 days and vital signs are stable, clear breath sounds and SpO2 97%. The night shift therapist hands you the following ABGs: pH 7.35, PaCO2 36 mmHg, PaO2 93 mmHg, HCO3 23 mEq/L on the following ventilator settings: PI = 22 cmH2O, TI = 0.35, f = 40, flow = 8 L/min, FiO2 = 55% and PEEP = 8 cmH2O. Based on these ABG results, what would you recommend?

Mr. Flowers a 65 year old man with COPD who is intubated for acute respiratory failure. He was placed on Volume Control on A/C 14, Vt 500 mL, FiO2 35%, PEEP 5 cmH2O and a flow 60 L/min. ABGs on the vent settings were: pH 7.44, PaCO2 34 torr, PaO2 110 torr, SvO2 0.77 and C(a-v)O2 4.4 vol%. Shortly after intubation he developed hypotension and a BTFDC was inserted at bedside. The following measurements are obtained:PAP:        45/24 mmHgPCWP:     6 mmHgCVP:        1 torrB/P:          90/60 (mean 70)SVR:         930 dynes.sec.cm-5C.O.:          3.8 L/minWhich of the following is the MOST likely cause for his condition?
