Physiology - Key points

 

 

Key Topics to learn

Respiratory

  • Oxygen cascade
  • Closing capacity
  • Compliance and P-V curve for lung and chest walls
  • Dead space (inc. vol vs capacity)
  • FRC and significance
  • O2 transport
  • O2 dissociation curve (O2, hemoglobin, myoglobin, cardiac output, 2,3DPG, sats)
  • CO2 transport
  • difference between top and bottom @ normal and low volume
  • Volume, pressure and flow during normal breathing
  • Preoxygenation and O2 store
  • Hypoxemia vs hypoxia
  • ?Pneumothorax
  • Flow-volume loop
  • Surfactant
  • non-respiratory functions of the lung
  • Effects of high altitude, diving
  • RBC and function (include pH, O2, CO2)
  • Mechanics of breathing
  • A-a gradient - neonate vs adult, effects of shunt and V/Q mismatch on pO2 and pCO2

 

Fluid

  • Water balance (thirst, ADH, etc)
  • Lymph
  • CSF
  • Tonicity
  • Osmolarity/osmolality
