Do you know what a spirometer is? Spirometer is a device used by doctors to measure lung function ability. Doctors use spirometers to measure how much air flow in and out of a patient’s lungs. What leads to the use of spirometers? Usually when patients complain of breathing difficulty or for smokers over 45 years of age. I never knew what a spirometer is before. Until a friend of mine, who’s husband was admitted into the hospital due to breathing difficulties, told me about the procedures. Her husband has been a smoker for more than 30 years. His diagnostic reported no serious health problems but doctors gave him a stern ultimatum to quit smoking immediately. So people, why smoke? Quit while you can.
