Spirometer- Usage and Maintenance

Spirometry which means “the measuring of breath,” is a routinely used pulmonary function test (PFT) that measures the amount and speed of air that a person can inhale and exhale. Results from the test can be used to estimate lung function and aid in the diagnosis of certain respiratory disorders.
A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive.

Let’s Learn Health Technology in Health Technology Management Series Topic-Spirometers Health technology  is defined by the World  Health  Organization as the "application of organized knowledge and skills in the form of devices, medicines, vaccines, procedures, and systems developed to solve a  health  problem and improve quality of lives“

3. Spirometry Spirometry is derived from the Latin words SPIRO (to breathe) and METER(to measure) Spirometry, which means “the measuring of breath,” is a routinely used pulmonary function test (PFT) that measures the amount and speed of air that a person can inhale and exhale. Results from the test can be used to estimate lung function and aid in the diagnosis of certain respiratory disorders.

5. Basics of Respiration The respiratory tract consists of the trachea, lungs, bronchi, bronchioles, and The alveoli constitute both the functional unit of the lung and the site of cellular respiration

6. Types of spirometers Bellows spirometers-measure volume ,mainly in lungs function unit. Electronic Desk top spirometer – Measure flow and volume with real time display . Small hand-held spirometers – Inexpensive and quick to use but not print

7. Spirometry –Possible side effects Feeling light-headed Headache Facial redness Fainting : Reduced venous return or vasovagal attack (reflax)s

8. Two important parameters PVC- Forced vital capacity, this is the total amount of air that you blow out in the breath. FEV1 – Forced Expiratory volume in one second , This is the amount of air you can blow out within one second .with the normal lungs and airways you can normally blow out most of the air from your lungs within one second.

9. User Maintenance Check List DAILY Cleaning the spirometer must be cleaned and disinfected internally at the Start of Stand, Weekly, and End of Stand Hoses Cleaning Clean the hoses , a ny hoses that have a leak will be thrown away 3.Hoses and hose adapters Used during a day will be changed daily. Used hoses and adapters will be stored in a plastic bag and placed in the belly compartment.

10. Troubleshooting Symptoms Possible Cause Solution The System does not operate when switch on The LCD Display back-light doesn't work Not connect ac/dc adapter Turn-off the instrument, connect the AC/DC adapter & Recharge battery completely Check the connection Check the power supply about 5 otherwise replace the displace
