Clinical guidelines for spirometry

Clinical guidelines for spirometry ensure accurate and reliable lung function testing. They recommend proper patient preparation, such as avoiding heavy meals or smoking before the test. The procedure involves the patient taking a deep breath and exhaling as forcefully as possible into a device that measures airflow and lung volume. The test should be repeated at least three times to get consistent results. Trained professionals oversee the process to ensure correct technique. These guidelines help diagnose and monitor respiratory conditions like asthma and COPD, ensuring results are accurate for proper treatment decisions.
