Calculate cardiac output using the Fick principle for the following values: Oxygen consumption 280 mL/min Arterial oxygen content 19.5 vol Mixed venous oxygen content 12 vol
 
  a. 2.1 L/min
  b. 3.7 L/min
  c. 7.5 L/min
  d. 20.5 L/min

Question 2

During the insertion of a pulmonary artery catheter, the balloon needs to be inflated with air when it enters which of the following?
 
  a. Right atrium
  b. Right ventricle
  c. Pulmonary artery
  d. Intrathoracic vessel

Answer to Question 1

ANS: B
C.O.O/(CO CO)x 10

Answer to Question 2

ANS: D
The balloon must be inflated as soon as it enters the intrathoracic vessel so that the catheter may be flow-directed by the balloon through the blood into the right atrium, right ventricle, and pul-monary artery. The inflation of the balloon also protects the heart from endocardial and pulmo-nary artery damage and ventricular arrhythmias.
