The Effect of Nasal CPAP
نویسنده
چکیده
It has been shown that nasal continuous positive airway pressure (nasal CPAP) significantly reduces nocturnal reflux both in patients with sleep apnea and in patients without sleep apnea but consistent abnormal nocturnal reflux. The mechanism by which CPAP is thought to reduce reflux includes the elevation of the resting lower esophageal sphincter (LES) pressure. In this study, we tested the effect of nasal CPAP in two groups of patients with aperistaltic esophagus but with different resting LES pressure. Seven patients with scleroderma esophagus and six patients treated for achalasia were tested over a 48-h period. On the first night, the patients were untreated; on the second night, both groups received applied nasal CPAP at 8 cm H20 pressure. The percentage of time the pH <4.0, the number of reflux events >5

Background The most common cause of admission to neonatal intensive care units (NICU) is respiratory distress syndrome. One of the respiratory assistance methods is using nasal continuous positive airway pressure (CPAP). Regarding the importance of pain control which is one of the major priorities in neonatal nursing care, this study aimed to evaluate the effect of body position on pain due to ...

Background: Respiratory distress syndrome (RDS) is a major cause of mortality among premature neonates. The present study was conducted to find out whether early nasal CPAP therapy could eliminate the need for mechanical ventilation in premature neonates with RDS. Materials and methods: For this clinical trial, premature neonates with RDS during the first 6 hours following the delivery were as...

BackgroundSeveral beneficial effects of non-nutritive sucking in infants, including the physiological stability, relaxation, better transition from tube feeding to oral feeding have been reported. But its effect on oxygen saturation in neonates under the Nasal Continuous Positive Airway Pressure (NCPAPو (is not so clear. This study aimed to investigate the effects of non-nutritive sucking on tr...
متن کاملNasal CPAP effect on patterns of sleep apnea.
To evaluate the effect of continuous positive airway pressure via nasal mask (nasal CPAP) on occlusive, mixed, and central apneas (OA, MA, and CA, respectively), we performed nocturnal polysomnography without and with nasal CPAP on 21 patients with sleep apnea. Three patients were unable to tolerate nasal CPAP. The remaining 18 patients had significant reductions in the overall apnea frequency ...

Background: Continuous positive airway pressure (CPAP) is used as respiratory support in preterm neonates; however, the best weaning method has not yet been determined. In this study, we compared sudden complete and gradual weaning from nasal CPAP (NCPAP) in preterm newborns. Methods: This randomized controlled trial was conducted on 62 prete...
متن کاملThe effect of nasal surgery on nasal continuous positive airway pressure compliance.
OBJECTIVES/HYPOTHESIS Nasal continuous positive airway pressure (CPAP) is the standard therapy for sleep apnea; however, compliance rates are historically poor. Among the most commonly cited reasons for nonadherence is nasal obstruction. Our study sought to examine if nasal surgery actually increases CPAP compliance. STUDY DESIGN Prospective case series. METHODS Nasal CPAP-intolerant obstru...
