Ever wondered how doctors measure how well your lungs absorb oxygen? Step back in time to the early 20th century, where a woman named Marie Krogh made a groundbreaking discovery. She introduced the single-breath technique to measure pulmonary diffusing capacity. This method, still used today, helps doctors understand how efficiently your lungs transfer oxygen into your bloodstream.

Krogh was a Danish physiologist who dedicated her life to studying the human body. She discovered that by having a person take a deep breath of a gas called nitrous oxide, she could measure how much of it their lungs absorbed. This quick and simple test became a game-changer in the field of pulmonary medicine.

But why is this important? Understanding your lung's diffusing capacity can help doctors detect and treat conditions like asthma, emphysema, and even lung cancer. Krogh's work paved the way for better diagnosis and treatment of these diseases.

Yet, her journey wasn't easy. As a woman in science during her time, Krogh faced many challenges. But her passion and dedication led her to make significant contributions to medical science.

So, the next time you take a deep breath, remember Marie Krogh. Her innovative idea continues to shape modern medicine and improve countless lives.
