A relatively large but interesting chapter.

Question Pattern

This is a relatively vast and busy chapter with multiple discrete concepts.

See if you can make yourself familiar with stuff like

  • Surfactatnt
  • Compliance
  • V/Q ratio
  • PFT in different conditions
  • Lung capacities, calculation
  • O2 dissociation curve
  • Respiratory centres

Chemoreceptors has been a very high-yield area.
