I've found some simple tests that you can do to test your lungs yourself at home. Please try if you like to and let me know if you think these make sense?
Also any other similar tests that you know of appreciated.
Here's a simple way to find out if you have the potential for respiratory problems associated with COPD. Using a stop watch, take a full breath; hold it for a second. Then, with your mouth open, blow out as hard and fast as you can. Your lungs should be completely emptied, meaning that you can blow no more air out even though you try, in no more than 4 to 6 seconds. If it takes you longer to blow out all the air, it means that airflow is obstructed or limited.
