Following 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 of A/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 and PAC the presence of bilateral infiltrates. pH = 7.53 Hgb = 14 gms PaCO2 = 35 mmHg PvO2 = 28 mmHg PaO2 = 33 mmHg SvO2 = 58 mmHg HCO3 = 26 mEq/L SaO2 = 78% PAC measurements reveal the following values: CVP = 12 mmHg BP = 140/80 mmHg PAP = 50/25 mmHg HR = 110 beats/min PCWP = 6 mmHg CO = 6.0 L/min Part 1: Interpret the ABG Part 2: What is the patient’s SVR? What is the patient’s PVR?
Case #4
Following 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 of
A/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 and
PAC the presence of bilateral infiltrates.
pH = 7.53
Hgb = 14 gms
PaCO2 = 35 mmHg
PvO2 = 28 mmHg
PaO2 = 33 mmHg
SvO2 = 58 mmHg
HCO3 = 26 mEq/L
SaO2 = 78%
PAC measurements reveal the following values:
CVP = 12 mmHg
BP = 140/80 mmHg
PAP = 50/25 mmHg
HR = 110 beats/min
PCWP = 6 mmHg
CO = 6.0 L/min
Part 1: Interpret the ABG
Part 2: What is the patient’s SVR? What is the patient’s PVR?
