Calculation Formula

IRV = VC - TV

Where:
IRV = Inspiratory Reserve Volume
VC = Vital Capacity
TV = Tidal Volume

What is Inspiratory Reserve Volume (IRV)?

Inspiratory Reserve Volume (IRV) is the maximum amount of air that can be inhaled after a normal inhalation. It is an important measure of lung function and can be used to assess respiratory health.

How to Use the Calculator

  1. Enter the Tidal Volume (TV) in liters. This is the normal amount of air inhaled or exhaled during breathing.
  2. Enter the Vital Capacity (VC) in liters. This is the maximum amount of air that can be exhaled after a maximum inhalation.
  3. Click the "Calculate" button to compute the Inspiratory Reserve Volume (IRV).
  4. The result will be displayed in liters.

Interpreting the Results

The Inspiratory Reserve Volume (IRV) can help in diagnosing respiratory conditions such as COPD, asthma, and restrictive lung diseases. A reduced IRV may indicate impaired lung function.

Precautions

Ensure that the values entered are accurate and reflect the patient's typical breathing pattern. Consult a healthcare professional for further interpretation of the results.
