Respiratory | Forced Spirometry & Pulmonary Function Test

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this pulmonary physiology lecture, Professor Zach Murphy breaks down the principles of Forced Spirometry, one of the most important diagnostic tools for evaluating lung function and distinguishing between obstructive and restrictive lung diseases. We begin by explaining the key phases of a forced vital capacity (FVC) maneuver, in which a patient exhales as forcefully and completely as possible after a full inspiration. You’ll learn how to interpret major spirometric values including: • FVC (Forced Vital Capacity) • FEV₁ (Forced Expiratory Volume in 1 second) • FEV₁/FVC ratio Enjoy the lecture and support us below! 🌐 Official Links Website: https://www.ninjanerd.org Podcast: https://podcast.ninjanerd.org Store: https://merch.ninjanerd.org 📱 Social Media   / ninjanerdlectures     / ninjanerdlectures     / ninjanerdlectures   https://x.com/ninjanerdsci/   / ninja-nerd   💬 Join Our Community Discord:   / discord   #ninjanerd #ForcedSpirometry #Respiratory
