Volume Oscillations Delivered to a Lung Model Using 4 Different Bubble CPAP Systems.
BACKGROUND High-frequency pressure oscillations created by gas bubbling through an underwater seal during bubble CPAP may enhance ventilation and aid in lung recruitment in premature infants. We hypothesized that there are no differences in the magnitude of oscillations in lung volume (ΔV) in a preterm neonatal lung model when different bubble CPAP systems are used. METHODS An anatomically re...
متن کاملEffects of condensate in the exhalation limb of neonatal circuits on airway pressure during bubble CPAP.
BACKGROUND Bubble CPAP is frequently used in spontaneously breathing infants with lung disease. Often bubble CPAP systems lack pressure alarms and pressure-release valves. We observed a large volume of condensate in the exhalation limb of a patient circuit and conducted a series of experiments to test the hypothesis that accumulated condensate could affect delivered pressures. METHODS An anat...
متن کاملInteractive Volume Rendering based on a "Bubble Model"
In this paper an interactive volume rendering technique is presented which is based on a novel visualization model. We call the basic method “bubble model” since iso-surfaces are rendered as thin semi-transparent membranes similarly to blown soap bubbles. The primary goal is to develop a fast previewing technique for volumetric data which does not require a time-consuming transfer function spec...
متن کاملBubble CPAP versus CPAP with variable flow in newborns with respiratory distress: a randomized controlled trial.
OBJECTIVE To evaluate the efficacy and safety of nasal continuous positive airway pressure (NCPAP) using devices with variable flow or bubble continuous positive airway pressure (CPAP) regarding CPAP failure, presence of air leaks, total CPAP and oxygen time, and length of intensive care unit and hospital stay in neonates with moderate respiratory distress (RD) and birth weight (BW) ≥ 1,500 g. ...
متن کاملImplementation of Bubble CPAP in a Rural Ugandan Neonatal ICU.
BACKGROUND Respiratory distress is a leading cause of neonatal death in low-income and middle-income countries. CPAP is a simple and effective respiratory support modality used to support neonates with respiratory failure and can be used in low-income and middle-income countries. The goal of this study was to describe implementation of the Silverman-Andersen respiratory severity score (RSS) and...
