How often should a spirometer be calibrated?
Spirometry is widely performed by a variety of health professionals in settings outside the traditional pulmonary function laboratory. It is important to very that test results are accurate, because they are used to establish diagnoses and guide therapy. A quality-control program will help verify the accuracy of testing procedures and must be developed based on equipment, personnel, and test application. Calibration is part of quality control and its meaning has evolved to include limited performance-testing. Large syringes and recently available flow calibrators allow determination of spirometer accuracy and make calibration rapid and convenient. They have the additional advantage of being portable and thus can accompany the spirometer on field trips. Calibration techniques may help in other aspects of quality control, such as test methodology and monitoring technician proficiency. Technicians are often evaluated on the ability to prepare, calibrate, and troubleshoot equipment, gain patient cooperation, determine the adequacy of effort, and calculate spirometry results. Calibration techniques may help in many aspects of this evaluation. Finally, advanced techniques may be used to study the methods used in performing clinical spirometry.
How often should a spirometer be calibrated?
Calibration or verification with an annually certificated calibration syringe needs to take place at every year (maximum) , or every every spirometry session (Recomended) for a busy service.
A biological control test (testing the equipment by having a healthy, stable person perform spirometry) should also be performed at least once a week.
The calibration can be done by professional organization or service center , it can be also sent back to Meditech and we will do for , but the round way freight cost is on buyer.
Spirometry Test: What Do My Spirometry Results Mean?
People living with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, emphysema and other types of chronic lung diseases have had a spirometry test. Typically, doctors use spirometry to help them better under the severity of your chronic lung disease symptoms and how they affect your life. We break down the key facts about a spirometry test and what your results mean.
What is a Spirometry Test?
Spirometry is a type of pulmonary function test (PFT). A spirometry test measures the amount of air you inhale, the amount of air you exhale and how quickly you exhale. In a spirometry test, your lungs are tested to see how well they are working. There are several measurements gained from spirometry. Some of the important measurements determined from a spirometry test include forced vital capacity (FVC), forced expiratory volume (FEV), forced expiratory volume in one second (FEV1) and total lung capacity (TLC).
Forced Vital Capacity (FVC) is the total amount of air you can exhale after taking the deepest breath possible.
Forced Expiratory Volume (FEV) is the amount of air you can forcefully exhale during the first, second and third seconds of the FVC test.
FEV1 or forced expiratory volume in one second is the amount of air you can forcefully exhale during the first second of the FVC test.
Total Lung Capacity (TLC) is the total amount of air in the lungs after inhaling a deep breath.
