Misconceptions about respiratory physiology are prevalent among medical students, with only 35% correctly answering a question on tidal volume during exercise. This highlights a need for improved foundational physiology education.

Area of Science:

  • Medical Education
  • Physiology
  • Respiratory System

Background:

  • Common misconceptions in physiology persist into advanced medical studies.
  • These can impede understanding of pathology and clinical medicine.
  • Investigating respiratory physiology misconceptions is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence of misconceptions in respiratory physiology.
  • To assess understanding of tidal volume changes during exercise among medical students.

Main Methods:

  • A single question regarding tidal volume during exercise was posed.
  • 153 MBBS students from years 1-4 participated.
  • Students selected the correct answer from three options.

Main Results:

  • Overall, 35% of students answered correctly.
  • First-year (45%) and fourth-year (43%) students showed higher correct response rates.
  • Second-year (27%) and third-year (8%) students had significantly lower correct answers.

Conclusions:

  • A notable prevalence of misconceptions in respiratory physiology exists among medical students.
  • Understanding varies across different years of medical education.
  • Targeted educational strategies may be needed to address these knowledge gaps.
