Ventilation Parameters

Question 1

Assuming no underlying pathology,

What is the Arterial Carbon Dioxide Partial Pressure (PaCO2)?

(Include Units)

Answer 1

35 - 44 mmHg

Question 2

Assuming no underlying pathology,

What is the Difference between ETCO2 and PaCO2 level?

(Include Units)

Answer 2

0 - 5 mmHg

Question 3

Assuming no underlying pathology,

What is the Physiologic Deadspace? (Vd)

(Include Units)

Answer 3

2 mL / Kg

Question 4

Assuming no underlying pathology,

What is the Deadspace to Tidal Volume Ratio? (Vd / VT)

(Include Units)

Answer 4

< 33 %

( ~2 mL/kg) / (6-8 mL / kg)

Vd = 2 mL/kg
TV = 6-8 mL / kg

Question 5

Assuming no underlying pathology,

What is the normal End Tidal Carbon Dioxide?

(Include Units)

Answer 5

30 - 40 mmHg
