BACKGROUND An estimated 15 million adults in the United States are affected by dysphagia (difficulty swallowing). Severe dysphagia predisposes to medical complications such as aspiration pneumonia, bronchospasm, dehydration, malnutrition, and asphyxia. These can cause death or increased health care costs from increased severity of illness and prolonged(More)
OBJECTIVE To determine accuracy of the 7-8-9 Rule in a cohort of neonates. STUDY DESIGN This study was cross-sectional in design. Seventy-five consecutive neonates who required oral intubation from June 2004 to November 2004 for cardiopulmonary failure, respiratory distress, or surfactant administration were the subjects of this study. The initial(More)
To evaluate the accuracy of the initial negative inspiratory pressure (PI) to maximal negative inspiratory pressure (PImax) ratio in predicting extubation outcome for intubated infants and children. A prospective study. Setting: Pediatric intensive care unit. A sample of 50 stable intubated pediatric patients who were judged clinically ready for extubation.(More)
Safely operating life support equipment and evaluating new technology both require some basic understanding of measurement theory. Measurement errors fall into two main categories: systematic errors (predictable problems usually due to calibration) and random errors (unpredictable). These two types of errors can be quantified by experiments involving(More)
We modified an algorithm for mechanical ventilation of infants with respiratory distress syndrome to create an interactive user-friendly computer program. To determine the effectiveness of this computer program, we evaluated the correction of deranged arterial blood gases in three groups of neonates: group I, treated before the introduction of the computer(More)
To compare high-frequency jet ventilation (HFJV) with pressure-limited time-cycled conventional ventilation (CV), we randomized 41 infants with clinical and radiographic evidence of respiratory distress syndrome during the first day of life to receive either HFJV or CV. Standardized ventilatory protocols were used for 48 hours, after which CV was(More)
There has been a dramatic increase in the number and complexity of new ventilation modes over the last 30 years. The impetus for this has been the desire to improve the safety, efficiency, and synchrony of ventilator-patient interaction. Unfortunately, the proliferation of names for ventilation modes has made understanding mode capabilities problematic. New(More)
To determine whether early use of high-frequency jet ventilation reduces neonatal mortality or pulmonary morbidity rates, we randomly selected 42 infants with clinical and radiographic evidence of severe respiratory distress syndrome to receive either high-frequency jet ventilation or conventional ventilation. Separate sequential analyses (two-sided, alpha(More)
BACKGROUND Limited data are available to describe the CPAP effects that can be expected when using high flow with a traditional nasal cannula. OBJECTIVE To describe the relationship between the pressure generated at the airway opening and flow through a nasal cannula using a simulated infant model. We hypothesized that positive pressure generated by a(More)
