[Comparison of the degree of peak expiratory flow (PEF) in children measured with a "Vitalograph" meter and automatic spirometer SA-02]. / Porównanie wielkosci szczytowego przeplywu wydechowego (PEF) u dzieci mierzonego miernikiem firmy "Vitalograph" i spirometrem automatycznym SA-02.

PEF values in 475 healthy children (age 9-15 years, 138 females, 337 males) measured with a Vitalograph meter and an automatic spirometer SA-02 were compared. The results were comparable in all except in 9, 10, 11 year old boys, in whom the PEF values measured with a Vitalograph meter were statistically higher in comparison with the readings given by the automatic spirometer. The authors have demonstrated the high reliability of the Vitalograph meter in assessing PEF.
