background and objectives: the weaning procedure of mechanical ventilation in many patients is a difficult and long process and increases the time of mechanical ventilation. there are numerous ways to achieve this goal. one common way is using cpap-ventilator. considering the lower price of blender-humidifier compared to cpapof ventilator and the limited number of studies in this field, this st...

Background: In this study, we aimed to compare ventilator-derived and bubble continuous positive airway pressure (CPAP) in neonates with respiratory distress syndrome admitted to Neonatal Intensive Care Unit of Vali-e-Asr Hospital, Birjand, Iran, in 2014. Methods: This cohort study was conducted among 68 patients assigned into two groups. The neonates in group A (32 infants) were treated with b...

OBJECTIVE To test the efficiency of the Bird Mark 7 ventilator adapted to deliver continuous positive airway pressure (CPAP) in noninvasive positive pressure ventilation. METHODS This was an experimental study using a mechanical model of the respiratory system. A Bird Mark 7 ventilator was supplied with 400 and 500 kPa and tested at CPAP of 5, 10 and 15 cmH2O. The following variables were ana...

Continuous Positive Airway Pressure (CPAP) ventilation remains a mainstay treatment for obstructive sleep apnea syndrome (OSAS). Good pressure stability and pressure reduction during exhalation are of major importance to ensure clinical efficacy and comfort of CPAP therapy. In this study an experimental CPAP ventilator was constructed using an application-specific CPAP blower/motor assembly and...

BACKGROUND Neonates with respiratory distress syndrome are often treated with nasal continuous positive airway pressure (CPAP). Nasal CPAP methods include electronic feedback control, underwater seal, flow opposition, and flow opposition with fluidic flow reversal on expiration. Few studies have compared those modes, and the results have been contradictory. METHODS We compared the effect of r...

INTRODUCTION The helmet may be an effective interface for the delivery of noninvasive positive pressure ventilation. The high internal gas volume of the helmet can act as a 'mixing chamber', in which the humidity of the patient's expired alveolar gases increases the humidity of the dry medical gases, thus avoiding the need for active humidification. We evaluated the temperature and humidity of ...

Background: Respiratory distress syndrome is one of the main complications associated with low birth weight, and a main cause of mortality in premature neonates. The present study aimed to compare the efficacy of ventilator continuous positive airway pressure (CPAP) and bubble CPAP in the treatment of respiratory distress syndrome (RDS) in premature neonates. Methods: This randomized controlled...

AIM To determine if a weaning regimen on flow driver continuous positive airway pressure (CPAP) would decrease the number of ventilator days but increase the number of CPAP days when compared with a rescue regimen. METHODS Fifty eight babies of 24-32 weeks gestation with respiratory distress syndrome (RDS) were studied prospectively. After extubation they were randomly allocated to receive CP...
