Robert Tiffeneau

Robert Tiffeneau was a notable French physician and professor recognized for his contributions to respiratory medicine, particularly in understanding lung function and disorders. His work, most famously encapsulated in the Tiffeneau Index, focuses on measuring the ratio of forced expiratory volume to forced vital capacity in a patient's lungs, helping to diagnose conditions like asthma and chronic obstructive pulmonary disease (COPD). This metric provides valuable insights into the airflow limitations in the lungs, making it easier to assess a patient's respiratory health and guide treatment decisions. His research has had a lasting impact on pulmonary medicine.
