Evaluation of the effectiveness of treatment for respiratory disease (asthma or COPD) - is it necessary to correct the treatment in other direction.
PEF (Peak Expiratory Flow) Test or peak expiratory flow rate measurement. This is a first-line examination of the function of the respiratory tract that compares your lung function with your age-group and gender-specific standards. The PEF meter is a small hand held device, the advantage of which is the quick testing and easy interpretation of results. If the PEF test values are lower than the expected in your case, then your doctor may want to send you to spirography as a precaution and further specifiying test .
Spirometry is a more detailed examination of the respiratory function compared to the PEF test, which measures respiratory volume and respiratory tract pressure (maximum depth and speed) when breathing. The study can be used to determine the decrease in pulmonary function, which occurs in case of various lung diseases. This is an important study in case of diagnosis and monitoring of tratment of common diseases such as asthma and chronic obstructive pulmonary disease.
This study requires active participation from your side, but does not hurt or involve significant health risks. The outcome depends to a large extent on cooperation between you and the medical staff and on your compliance with the orders. In calculation of spirography results a ratio of two indexes in comparing with reference values is evaluated. Your age, length, and gender affect the lung volume and are taken into account in calculating the results. For example, asthma is diagnosed when the FEV1 / FVC ratio is less than the reference value. Low values indicate that your respiratory tract has narrowed and is a typical indication of asthma. Usually, spirography is repeated in this case after you have received a medicine to relax your breathing. If you have asthma, then after inhaling the medicine, your peak expiratory flow will increase.
Before the examination:
It is expedient to postpone spirogratifia in case of acute respiratory infections. Study contraindications include severe heart disease, i.e. arrhythmia, recent cerebrovascular case, haemorrhage, recent extensive surgery.
