defintions

• ventilation (L/min)

  amount of air that can be inspired or expired per minute

  V= TV x RR
• tidal volume

  amount of air breathed in or out per breath
• respiratory rate

  number of breaths taken per minute
• cardiac output (Q)

  amount of blood pumped out of the heart per minute

  Q(L/min)= SV x HR
• stroke volume


  amount of blood pumped out of the left ventricle of the heart per beat
• heart rate


  number of times the heart beats per minute
• oxygen deficit 


  when oxygen supply doesn’t meet oxygen demand
• steady state


  oxygen supply equals oxygen demand
