Resonance frequency in respiratory distress syndrome.
AIM To observe how the resonance frequency changes with the course of respiratory distress syndrome (RDS), by examining the effect of changing static compliance on the resonance frequency in premature infants. METHODS In 12 ventilated premature infants with RDS (mean gestational age 26.6 weeks, mean birth weight 0.84 kg), resonance frequency and static compliance were determined serially usin...
متن کاملDetermination of resonance frequency of the respiratory system in respiratory distress syndrome.
AIM To measure tidal volume delivery produced by high frequency oscillation (HFO) at a range of frequencies including the resonance frequency. METHODS Eighteen infants with respiratory distress syndrome were recruited (median gestation 28.7 weeks). Each was ventilated at frequencies between 8 and 30 Hertz. Phase analysis was performed at various points of the respiratory cycle. HFO was provid...
متن کاملHigh-frequency oscillation in early adult respiratory distress syndrome
Methods Objective: The aim of the study was to compare HFOV with a conventional ventilation strategy that used low tidal volumes and high levels of positive end-expiratory pressure in patients with new-onset, early (<72 hours) moderate to severe ARDS. Design: A multicenter, randomized, controlled trial was conducted in 39 ICUs in five countries. Setting: Participants were adults with new-onset,...
متن کاملHigh-frequency oscillation in early acute respiratory distress syndrome.
BACKGROUND Previous trials suggesting that high-frequency oscillatory ventilation (HFOV) reduced mortality among adults with the acute respiratory distress syndrome (ARDS) were limited by the use of outdated comparator ventilation strategies and small sample sizes. METHODS In a multicenter, randomized, controlled trial conducted at 39 intensive care units in five countries, we randomly assign...
متن کاملHaemodynamic changes during high frequency oscillation for respiratory distress syndrome.
In a crossover trial left ventricular output (LVO), cerebral blood flow velocity (CBFV), and resistance index (RI) of the anterior cerebral artery were compared using Doppler ultrasonography, in eight preterm infants with respiratory distress syndrome (RDS) during conventional mechanical ventilation and high frequency oscillation. LVO was 14% to 18% lower with high frequency oscillation. There ...
