Can peak expiratory flow be measured accurately during a forced vital capacity manoeuvre?
Spirometry and peak flow measurements traditionally depend on different forced expiratory manoeuvres and have usually been performed on separate, dedicated equipment. As spirometry becomes more widely used in primary care settings, the authors wished to determine whether there was a systematic difference between peak expiratory flow (PEF) derived from a short sharp exhalation (PEF manoeuvre) an...
متن کاملNormal values of forced vital capacity (FVC), forced expiratory volume (FEV 1-0), and peak flow rate (PFR) in children.
In children, the respiratory tract is probably more often affected by disease than any other system of the body. In spite of this, quantitative methods of evaluation are seldom used outside special respiratory units. No clinician would manage a patient with potential renal failure without laboratory aids, even if it were only an estimation of the blood urea, but he would seldom give children wi...
متن کاملComparison of Peak Expiratory Flow Rate and Forced Vital Capacity between Petrol Pump Workers and Automobile Repair Workers
Urbanization has led to enormous increase in number of automobiles and in order to cater them petrol filling stations and workshops for repairing the vehicles had also increased accordingly. Workers engaged in these places are continuously exposed to petrol and diesel fumes which can take a toll on their health. Respiratory system is the most affected one as the fumes are volatile. The present ...
متن کاملComparison of abdominal muscle activity and peak expiratory flow between forced vital capacity and fast expiration exercise
[Purpose] The purpose of this investigation was to compare the activities of the abdominal muscles and peak expiratory flow between forced vital capacity and fast expiration exercise. [Subjects and Methods] Fifteen healthy male participated in this study. Peak expiratory flow and electromyographic activities of the rectus abdominis, external oblique, and internal oblique/transversus abdominis m...
متن کاملPerformance of forced expiratory manoeuvre in children.
The negative expiratory pressure (NEP) method has been previously used to assess the performance of forced vital capacity (FVC) manoeuvre in normal adults. The aim of the present study is to assess whether flow limitation is achieved during FVC manoeuvres in children aged 6-14 yrs. NEP (-10 cmH2O) was successfully applied in 177 normal children, the portion of FVC over which expiratory flow did...
