Questions and Answers

What is the equation for cardiac output (Q)?

  • Q = SV / HR
  • Q = SV * HR (correct)
  • Q = SV + HR
  • Q = SV - HR

    • What is the formula for mean arterial pressure (MAP)?

  • MAP = (1/3) * SBP + (2/3) * DBP (correct)
  • MAP = SBP - DBP
  • MAP = SBP * DBP
  • MAP = SBP / DBP

    • What does the VD/VT ratio measure?

  • Heart rate
  • Gas exchange efficiency (correct)
  • Blood volume
  • Respiratory rate
