After 2 h the initial electrical conductivity (EC1) was measured using an electrical conductivity meter.
Patients underwent four episodes of deep breathing and coughing exercises using an incentive spirometer (volumetric).
PEF was evaluated twice daily in all children using an electronic spirometer (AS-300; Minato Medical Inc., Tokyo, Japan).
Spirometry was carried out using an electronic spirometer (SpiroStar DXMedikro, L21, St-Germain-en-Laye, France).
Spirometry was carried out in the sitting position, using an electronic spirometer (Oscilolink, Datalink, Montepellier, France).
Spirometry was performed using an EasyOne spirometer (ndd Medical Technologies, Andover, MA).
The spirometric tests were performed according to American Thoracic Society ATSspecificationsons (ATS 1995) using an EasyOne spirometer (ndd Medical Technologies, Andover, MA, USA).
