BACKGROUND: This study aimed to determine whether reducing the expiratory pressure during nasal positive airway pressure for reasons of comfort causes a substantial decrease in the upper airway calibre. METHODS: Eight patients with obstructive sleep apnoea were studied. Continuou...

Crew, A. D., Varkonyi, P. I., Gardner, L. G., Robinson, Q. L. A., Wall, E., and Deverall, P. B. (1974).Thorax, 29, 437-445. Continuous positive airway pressure breathing in the postoperative management of the cardiac infant. Continuous positive airway pressure with spontaneous ve...

OBJECTIVE: The effects of acute continuous positive airway pressure therapy on left ventricular diastolic function and functional capacity in patients with compensated systolic heart failure remain unclear. METHODS: This randomized, double-blind, placebo-controlled clinical tr...

Over a period of six months, seven cases were documented of trauma to the nose as a result of flow driver continuous positive airway pressure in babies of very low birthweight (VLBW). There was a complication rate of 20% in the babies who required it. Deformities consisted of col...

BACKGROUND--Patients with the sleep apnoea/hypopnoea syndrome often receive continuous positive airway pressure to improve their symptoms and daytime performance, yet objective evidence of the effect of this treatment on cognitive performance is lacking. METHODS--A prospective pa...

OBJECTIVE: To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS: Overnight polysomnography was performed by a computerized system in 19 subjects ...

OBJECTIVE: There are several treatments for obstructive sleep apnea syndrome, such as weight loss, use of an oral appliance and continuous positive airway pressure, that can be used to reduce the signs and symptoms of obstructive sleep apnea syndrome. Few studies have evaluated ...

OBJECTIVES: The aim of the current study was to compare the objective and subjective effects of continuous positive airway pressure to the use of nasal dilator strips in patients with acromegaly and moderate to severe obstructive sleep apnea. METHODS: We studied 12 patients with ...

Seven patients with the severe obstructive sleep apnoea syndrome were treated with nasal continuous positive airway pressure for from three to 22 months. This treatment reversed all symptoms due to the syndrome in every patient and continued to be used in five patients. One patie...

Three cases of severe community acquired pneumonia requiring ventilatory support are presented. Continuous positive airway pressure (CPAP) applied via a tightly fitting face mask was used and was successful in two cases; the third required intermittent positive pressure ventilati...

Non-apnoeic oxygen desaturation related to rapid eye movement (REM) sleep in a patient with hypothyroidism, obesity, respiratory failure, and cardiac failure was improved by treatment with nasal continuous positive airway pressure of 10 cm H2O....

Continuous positive airway pressure (CPAP) is the simplest form of noninvasive ventilation. Mechanical ventilators designed to invasive ventilation, ventilators specifically designed to noninvasive ventilation (NIV-Ventilator) and continuous flow generators can provide CPAP. The ...

OBJECTIVE: To compare the effects of 3 types of noninvasive respiratory support systems in the treatment of acute pulmonary edema: oxygen therapy (O2), continuous positive airway pressure, and bilevel positive pressure ventilation. METHODS: We studied prospectively 26 patients wi...

The pattern of breathing was studied in 13 premature newborns treated by variable‐flow Nasal Continuous Positive Airway Pressure (NCPAP), conventional NCPAP, and nasal cannulae. Compared to constant‐flow NCPAP and nasal cannulae, the variable‐flow NCPAP increases tidal volume and...

OBJECTIVES: This study evaluated the effect of Continuous Positive Airway Pressure treatment on oxidative stress parameters and the quality of life of elderly patients with obstructive sleep apnea syndrome. METHODS: In total, 30 obstructive sleep apnea syndrome patients and 27 su...

OBJECTIVE: To investigate the effect of obstructive sleep apnea and continuous positive airway pressure treatment on serum butyrylcholinesterase activity and ischemia-modified albumin levels. METHODS: Thirty-two patients with obstructive sleep apnea and 30 age- and sex-matched c...

OBJECTIVES: Nasal continuous positive airway pressure is used as a standard of care after extubation in very-low-birth-weight infants. A pressure of 5 cmH2O is usually applied regardless of individual differences in lung compliance. Current methods for evaluation of lung complian...

The aim of the present study was to compare the clinical findings and polysomnography results obtained at public and private clinics in Brazil, the follow-up after diagnosis, and the therapeutic aspects related to continuous positive airway pressure. Patients who snore and who ha...
