Introduction

Using a polythene roll, about 2m long, one ties a knot to one end and seals it thus. Blowing into what is now a long polythene bag through the other end, one can inflate the bag and estimate/measure one's lung capacity

Tools

Parts

  1. Take a thin Polythene Bag of  5  feet in length. Tie a rigid knot at one end of the Polythene bag to seal it. "Closed" end.
    • Take a thin Polythene Bag of 5 feet in length.

    • Tie a rigid knot at one end of the Polythene bag to seal it.

    • "Closed" end.

    • "Open" end.

  2. Place the open end of the bag around your mouth in such a way that air won't escape when you blow. Now, Take a deep Breath and blow into the bag at one go With hand, Twist and close the "open" end of the bag  as soon as you blew into it.
    • Place the open end of the bag around your mouth in such a way that air won't escape when you blow.

    • Now, Take a deep Breath and blow into the bag at one go

    • With hand, Twist and close the "open" end of the bag as soon as you blew into it.

    • Squeeze the bag from "Open" end towards "Closed" end so that the air fills up and occupies the volume of the bag properly.

  3. Use a table, if you can. It will be much easier to take measurements. Measure the air filled portion of the bag against a 1 L plastic bottle. Mark the  position of  bottle with a marker and move the bottle over to the marked position to continue with the measurement process.

    • Measure the air filled portion of the bag against a 1 L plastic bottle.

    • Mark the position of bottle with a marker and move the bottle over to the marked position to continue with the measurement process.

    • Measure till end of air filled portion of the bag

  4. Add the volume of the bottle  you needed for the measurement process and you will arrive at approximated Capacity/Volume of your lungs!
    • Add the volume of the bottle you needed for the measurement process and you will arrive at approximated Capacity/Volume of your lungs!

    • For the case illustrated here : 1 L + 1 L + 0.8 L = 2.8 Litre approximately

    • Letting air escape when you blow into the bag - Hold the bag tightly to your mouth.

    • Failure to secure the "open" end of the bag immediately after blowing into it.

    • Not Squeezing the bag before taking measurements.

    • Loose knot at "closed" end.

    • Collect a sample from another person . Measure and compare the results to arrive at whose lungs are healthier!
