🫁 What is Lung Capacity?

According to the American Lung Association, lung capacity refers to the total amount of air your lungs can hold.

Key measurements: Total Lung Capacity (TLC), Vital Capacity (VC), and Forced Vital Capacity (FVC).

📊 Normal Values & Factors

Based on NHLBI guidelines, normal lung capacity varies by:

  • Age (decreases ~20ml per year after 25)
  • Height (taller = larger capacity)
  • Gender (males typically 20-25% higher)
  • Fitness level and smoking history

💡 Improving Lung Health

Recommendations from CDC respiratory health guidelines:

  • Regular aerobic exercise
  • Deep breathing exercises
  • Avoid smoking and secondhand smoke
  • Maintain good air quality indoors
