ANECDOTE

Why She Did A Mock Viva

  • Susanna joined the viva because her study group used the podcast and a friend contacted the hosts to arrange practice.

ADVICE

Treat The Viva Like A Colleague Discussion

  • Dan (Stan) says the exam tests communication and collaboration, not just knowledge.
  • Practice explaining and engaging with examiners like colleagues to improve performance.
INSIGHT

  • The alveolar gas equation explains why alveolar PO2 falls from ~160 to ~100 mmHg.
  • Humidification, barometric pressure, and CO2/R (via PA CO2 / R) determine alveolar oxygen tension.
