Breathing apparatus Spirometer:
An electrical device with many types, which share the same idea is the measurement of lung function, and may be used instead of the device of measurement of maximum blowing capacity when the examination of the decline of various types.
- The most important measurements measured by this device are two measures:
- Maximum blowing volume in one second (1FEV).
- Total blown air volume (FVC).
- Method of taking the measurements mentioned:
1. Take a very deep inspiration.
2 - blowing strongly as strongly as possible.
3. The device will measure the air volume in liters in the first second, the maximum blowing volume in one second (FEV), and measure the total blown air volume (FVC).
- Analysis: If the maximum blowing volume in one second (FEV)
ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
Total blown air volume (FVC)
- Less than (70%) the probability of asthma is great.
- (80%) and more in natural person.
- Notes:
1. In the normal person, most of the air comes out in the first second and the rest in the next four seconds.
2 - It is best not to use this device in children because the lung is small.
3. In the presence of any disease blocked airways such as asthma or clogged channels of chronic pulmonary disease COPD)), the inflatable air process takes longer to air is ejected from the lung from the normal person, so the best measure of the blockage of channels aerobic is (bloating capacity in the first second Spirometer is more than a maximum blowing capacity.
