In this teaching session for medical students preparing for their final ISCE exam, the focus will be on data interpretation for spirometry and lung function tests. Participants will learn how to analyze and interpret results from these assessments, emphasizing the identification of key findings, understanding relevant parameters such as FEV1, FVC, and the FEV1/FVC ratio, and correlating results with clinical scenarios. The session will cover common respiratory conditions associated with abnormal findings, facilitating a comprehensive understanding of pulmonary pathophysiology. Through interactive discussions and case studies, students will enhance their diagnostic skills and clinical reasoning. The session will conclude with a summary of important concepts and a Q&A segment to address any questions from participants.
