Continuous positive pressure ventilation and oxygen delivery.
نویسندگان
چکیده
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 reintroduction of intermittent positive pressure. The decline in cardiac output was not accompanied by hypotension. The application of continuous positive pressure requires careful assessment of systemic effects to determine its usefulness.

Effectiveness of Nasal Intermittent Positive Pressure Ventilation versus Nasal Continuous Positive Airway Pressure in Preterm Infants after Less Invasive Surfactant Administration
Background Non-invasive ventilation is increased used in preterm infants. We aimed to compare the effectiveness of nasal intermittent positive pressure ventilation (nIPPV) versus nasal continuous positive airway pressure (nCPAP) in preterm infants with respiratory distress syndrome (RDS) after less invasive surfactant administration (LISA). Materials and Methods In this clinical trial, eighty ...
متن کاملNew modalities for non-invasive positive pressure ventilation: A review article
Efficiency of non-invasive positive pressure ventilation in the treatment of respiratory failure has been shown in many published studies. In this review article, we introduced new modalities of non-invasive ventilation (NIV), clinical settings in which NIV can be used and a practical summary of the latest official guidelines published by the European Respiratory Clinical Practice. Clinical tri...
متن کاملEarly Nasal Intermittent Positive Pressure Ventilation (NIPPV) versus Nasal Continuous Positive Airway Pressure (NCPAP) for Respiratory Distress Syndrome (RDS) in Infants of 28-36 weeks gestational age: a Randomized Controlled Trial
Background: Early nasal continuous positive airway pressure (NCPAP) has emerged as a primary modality of respiratory support for preterm infants withrespiratory distress syndrome (RDS). However, 30%-40% of these newborns need subsequent mechanical ventilation. Nasal intermittent positive pressure ventilation (NIPPV) is a promising alternative to NCPAP, especially in po...

A 3200 g male infant was born at 40 weeks gestation to a 40-year-old gravida 4, para 3 mother. Pregnancy was uneventful and the infant was born via normal spontaneous vaginal delivery. The infant developed marked respiratory distress upon delivery and the heart rate remained below 100/min, for which the infant received positive pressure ventilation for 30 seconds with a bag and mask, then admit...
متن کاملComparison of Nasal Non-invasive Ventilation Methods in Preterm Neonates with Respiratory Distress Syndrome
Background: Humidified heated high flow nasal cannula (HHHFNC), nasal continuous positive airway pressure (NCPAP), and nasal intermittent positive pressure ventilation (NIPPV) are three nasal non-invasive ventilation methods. The purpose of this study was to compare these three methods in decreasing intubation and mechanical ventilation rate in preterm neonates with respiratory distress syndrom...
