The American Sleep Disorders Association recommends that oral appliances (OAs) be used in patients with primary snoring or mild obstructive sleep apnea (OSA) and in patients with moderate to severe OSA1,2 who are intolerant of or refuse treatment with nasal continuous positive airway pressure (nCPAP). Because of the life-threatening implications of a number of sleep disorders, it is imperative ...

We conducted this study to investigate the efficacy of the silicon gel application on the nares in prevention of nasal injury in preterm infants ventilated with nasal continuous positive airway pressure (NCPAP). Patients (n=179) were randomized into two groups: Group 1 (n=87) had no silicon gel applied to nares, and in Group 2 (n=92), the silicon gel sheeting was used on the surface of nares du...

The effectiveness and cost-utility of nasal continuous positive airway pressure (nCPAP) treatment was evaluated in obstructive sleep apnoea syndrome (OSAS), using a 15D health-related quality of life (HRQoL) instrument in a routine clinical setting. In total, 78 OSAS patients (43 receiving nCPAP; 35 receiving lifestyle guidance) were included in the study. nCPAP treatment had a minor effect on ...

AIM To review 66 children with obstructive sleep apnoea (OSA) for whom a trial of nasal continuous positive airway pressure (nCPAP) was proposed. METHODS Baseline sleep studies were performed to assess OSA severity; a trial of nCPAP was performed where moderate to severe OSA, not relieved by adenotonsillectomy, was found. The nCPAP trial was considered either technically successful (ST), if t...

The calibre of the upper airway is thought to be dependant upon its passive anatomy/collapsibility and the activation of pharyngeal dilator muscles. During awake periods, the more collapsible upper airway in obstructive sleep apnoea (OSA) increases the dilator muscle activity through a negative-pressure reflex. A direct correlation between the critical closing pressure (P(crit)), as a measure o...

The case of a patient with diffuse idiopathic skeletal hyperostosis (DISH) and upper airway oedema, is described. The patient presented with alveolar hypoventilation and obstructive apnoeas during sleep. Intravenous steroids (methylprednisolone, 160 mg.day-1) for 5 days did not reduce the oedema. However, it was rapidly reversed by the use of nasal continuous positive airway pressure (nCPAP). I...

The improvement in the severity of obstructive sleep-related breathing disorders during nasal continuous positive airway pressure (NCPAP) therapy can account for the decrease in the required NCPAP level with time. The aim of this study was to prospectively quantify the changes in the required NCPAP level over time of use in sleep apnoea-hypopnoea syndrome (SAHS). Forty sleep apnoea-hypopnoea pa...

Heated, humidified, high-flow nasal cannula (HHFNC) is frequently used as a noninvasive respiratory support for preterm infants with respiratory distress. But there are limited studies that compares HHFNC with nasal continuous positive airway pressure (nCPAP) only as the initial treatment of respiratory distress in preterm infants immediately after birth. The aim of this study is to assess the ...
