Clement Clarke have used their respiratory expertise to develop a wide range of Spirometers.
A Spirometer is a device that measures lung volumes, through the forced expiration of air in a patients' lungs. Spirometer readings are accurate and there are well-defined normal ranges that allow for the effects of age, sex and height
Spirometers can be used for the following tasks::
-
Distinguishing between obstructive disorders (COPD, Asthma) and restrictive disorders.
-
Diagnosing and evaluating the severity of COPD and other lung diseases.
-
Assessing the extent of abnormalities
- Judging responses to therapy
-
Determining progression of lung diseases.
The standard measurements that our Spirometer's perform are:
-
Peak Expiratory Flow (PEF)
The maximum amount of airflow from a patient during a forced expiration -
Forced Expired Volume in One Second (FEV1)
How much air can be exhaled in the first second of exhalation.
The One Flow FVC Screen and FVC Memo models both measure PEF, FEV1 and the following measurements:
-
Forced Vital Capacity (FVC)
The maximum volume of air that can be forcibly expired. -
Ratio of FEV1/FVC as %
The proportion of total volume that can be expired in the first second of expiration.
