The average expiratory reserve volume or ERV is 810.

<h3>What is expiratory reserve volume?</h3>
  • Expiratory reserve volume or ERV is the amount of air that is exhaled forcibly.
  • This can be measured using a spirometer and is used to detect restrictive lung diseases.
  • It is the maximum amount of air that can be exhaled after normal tidal volume is exhaled.
  • Respiratory volume is the volume of air which is either inhaled, exhaled or stored in your lungs.
  • The doctors estimate the reserve volume with the help of spirometer to determine some lung diseases.
  • Once diagnosed with a lung disease, spirometry is used to monitor it.
  • Here, 3 readings of ERV are taken, calculate the sum of the these and divide by 3 to calculate the average ERV.
  • ERV= (800+ 850+ 780)/ 3= 810
