Our lungs help us breathe and stay healthy. One way to check lung health is by measuring something called Expiratory Reserve Volume (ERV).

Why Is ERV Important?
ERV helps doctors see how well your lungs are working. It can show if there are any problems.
How Is ERV Measured?
ERV is measured using a test called spirometry. This test is simple and quick.
Spirometry Test Steps:
- You sit down and put a clip on your nose.
- You take a deep breath in and blow out as hard as you can into a tube.
- The machine measures the amount of air you blow out.
Normal ERV Values
ERV values can be different for everyone. It depends on age, sex, and size.
| Age Group | Average ERV (liters) |
|---|---|
| Children (5-12 years) | 0.7 – 1.2 |
| Teens (13-19 years) | 1.2 – 1.7 |
| Adults (20+ years) | 1.0 – 2.0 |

Factors Affecting ERV
- Smoking: Smoking can lower ERV.
- Exercise: Regular exercise can improve ERV.
- Health Conditions: Conditions like asthma can affect ERV.
- Obesity: Being overweight can lower ERV.
Improving ERV
There are ways to help improve your ERV and keep your lungs healthy.
Tips To Improve Erv:
- Quit smoking to protect your lungs.
- Exercise regularly to strengthen your lungs.
- Eat a balanced diet to stay healthy.
- Visit your doctor for regular check-ups.
