Redistribution of Alveolar Pressure During Continuous Positive Pressure Ventilation with End Inspiratorg Pause

A Comparison between Nasal Intermittent Positive Pressure Ventilation and Nasal Continuous Positive Airway Pressure Ventilation in the Treatment of Neonatal Respiratory Distress Syndrome

Background: Nasal intermittent positive pressure ventilation (NIPPV) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. The present study was conducted to compare the efficacy of NIPPV and nasal continuous positive airway pressure ventilation (NCPAP) in reducing the need for intubation in preterm infants with respiratory distress syndrome (RDS)....

Heterogeneity in ventilation during positive end-expiratory pressure

geneity in ventilation be good’ [1] and the related article by Zhao and colleagues [2]. We agree with the comments that instead of incremental positive end-expiratory pressure (PEEP) levels, a decremented PEEP titration might be an attractive option for determining optimal PEEP [1,3]. However, we feel that physiological inhomogeneity in ventilation and perfusion related to the gravitational eff...

Intraocular Pressure during Continuous Positive Airway Pressure

Continuous positive pressure ventilation and oxygen delivery.

The effects of intermittent and continuous positive pressure were studied in mechanically ventilated healthy dogs. No statistically significant changes were produced in oxygen tension, carbon dioxide tension, alveolar-arterial gradients or shunts by continuous positive pressure. It did produce a significant reduction in cardiac output and total oxygen delivery which was reversed by the reintrod...

Comparison of the pressure time product during synchronous intermittent mandatory ventilation and continuous positive airway pressure.

OBJECTIVE To compare the effect of continuous positive airway pressure (CPAP) with synchronous intermittent mandatory ventilation (SIMV) during weaning, by measurement of the pressure time product (PTP). The PTP is an estimate of the metabolic work or oxygen consumption of the respiratory muscles. PATIENTS Forty children, median age 14 months (range 1 month to 17 years) were studied immediate...
