Breath of Knowledge: An Interactive Computer-Based Program and Group Exercise to Teach Gas Exchange.

Area of Science:

• Medical Education
• Physiology
• Pulmonary Medicine

Background:

• Pulmonary gas exchange principles are complex and challenging for medical trainees.
• Computer-based learning offers interactive educational opportunities, but its impact on gas exchange mastery is underexplored.

Purpose of the Study:

• To assess if an interactive, clinically relevant computer program and small-group exercises enhance medical student learning of gas exchange principles.
• To measure learning gains via performance on multiple-choice questions related to gas exchange.

Main Methods:

• A pre-post study design compared medical student exam scores before and after implementing a computer-based gas exchange program.
• The program was integrated into small-group sessions with manual-based experiments.
• Exam questions were categorized as relevant or non-relevant to the program's reinforced principles.

Main Results:

• Both control and intervention groups showed significant score improvements (P < 0.001).
• The intervention group demonstrated a greater, though not statistically significant, improvement in gas exchange-related questions (P = 0.09).
• The majority of students found the program satisfactory and more beneficial than traditional lectures.

Conclusions:

• The interactive computer program serves as an effective strategy to reinforce pulmonary gas exchange principles in medical education.
• This resource can be adapted for various educational settings by tailoring cases and exercises to diverse learner needs.
• It offers a valuable alternative to traditional didactic lectures, particularly in contexts with limited laboratory work.
