RESUMO

BACKGROUND: There are no reports on the physiological effects of the Expiratory Flow lncrease Technique (AFE, ITomthe original French description "Augmentation du Flux Expiratoire"), fast (AFER, ITomthe original French description "Augmentation du Flux Expiratoire Rapide") or slow (AFEL, from the original French description "Augmentation du F/ux Expiratoire Lente"), in children with acute respiratory failure (ARF), in spite of their widespread use. This study aimed to evaluate and compare pulmonary function (PF) parameters in children with ARF during AFER and AFEL on two time points of mechanical ventilation. METHODS: 29 children, younger than 2 years, with ARF on Synchronized lntermittent Mandatory Ventilation, were submitted to AFER and AFEL, started on a mandatory phase of a ventilation cycle (AFERcim and AFELcim) and started on the assisted phase ofa ventilation cycle (AFERca and AFELca). PF measurements were performed with the CO2SMO Plus@ monitor (Dixtal, Brazil). The variables analyzed were Peak Expiratory Flow (PEF), Expiratory Tidal Volume, Exhaled CO2 Volume, and End-Tidal CO2 (EtCO2). Values obtained during AFEL and AFER were compared to baseline. Statistical analysis was performed by Wilcoxon s testo RESULTS: AFELcim caused statistically significant increases in ETCO2, (mean 47 mmHg, mino31mmHg, max. 62 mmHg; p
