continous positive airway pressure effect

Gugger, Bassetti
Nasal continuous positive airway pressure (n-CPAP) is an effective treatment for the obstructive sleep apnea syndrome (OSAS). It is currently regarded as the first line therapy for OSAS. The principal indication for n-CPAP treatment is daytime sleepiness. Nasal-CPAP improves daytime sleepiness dramatically in severe cases and the effect is objectively measurable with the multiple sleep latency test (MSLT). It is noteworthy that n-CPAP also improves symptoms, subjective daytime sleepiness, cognitive function, IQ, mood, quality of life and driving ability already in patients with mild sleep apnea with an apnea/hypopneaindex (AHI) between 5 and 15 per hour of sleep during overnight polysomnography...

OBJECTIVE: To compare breathing patterns and lung function in the supine, lateral, and prone positions in oxygen-dependent preterm infants. STUDY DESIGN: Respiratory function in preterm infants receiving nasal continous positive airway pressure therapy for mild respiratory failure was evaluated by respiratory inductive plethysmography. Infants were randomized to supine, left lateral, and prone positions for 3 hours. A nest provided a semiflexed posture for the infants placed in the left lateral position, similar to the in utero position...

Continous positive airway pressure (CPAP) is used to treat infant respiratory distress syndrome and apnea of prematurity, but its mode of action is not fully understood. We hypothesised that CPAP increases lung volume and stabilises respiratory control by decreasing loop gain (LG). Experimentally induced periodic breathing (PB) in the lamb was terminated early by CPAP in a dose-dependent manner, with a control epoch of 45.4+/-5.1s at zero CPAP falling to 32.9+/-5.4, 13.2+/-4.2 and 9.8+/-3.1s at 2.5, 5 and 10 cmH(2)O, respectively (p<0...

Obstructive sleep apnea (OSA) is a common medical condition that occurs in approximately 5% to 15% of the population. It is usually associated with an increased risk of cardiovascular disease. Diagnosis of OSA is based on polysomnography, and its severity is measured with an apnea-hypopnea index. Most of the adverse effects of OSA on the cardiovascular system are reversible with treatment. In addition to continous positive airway pressure therapy, precautions such as weight loss, avoidance of central nervous system depressants, treatment of nasal congestion and sleeping in the lateral position may help to treat OSA...

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is present in 44% of patients scheduled for bariatric surgery. Respiratory dysfunction associated with this syndrome is attributable to chronic obstructive pulmonary disease (COPD) and/or obesity hypoventilation syndrome (OHS). We studied the long-term effect of bariatric surgery on weight loss, on the respiratory comorbidities associated with obesity, and on the need for non-invasive positive pressure ventilation. METHODS: We followed a sample of patients with respiratory co-morbidity scheduled for open Capella Roux-en-Y gastric bypass (RYGBP) over 5-years...

Serum levels of C-reactive protein (CRP) were measured in 96 consecutive patients with obstructive sleep apnea syndrome (OSAS) before and after nasal continous positive airway pressure treatment. CRP levels only displayed significant correlations with body mass index (BMI) before treatment. No significant changes were observed in BMI and CRP levels after 9 months of treatment. These data suggest that CRP levels in patients with OSAS may be associated with obesity rather than OSAS itself.

BACKGROUND: Comparison of theophylline and nasal continous positive airway pressure-ventilation (nCPAP) in patients non eligible for surgical treatment with obstructive sleep apnea. PATIENTS AND MATERIALS: In a prospective non-randomized study 60 patients with mild obstructive sleep apnea were investigated. All individuals were not eligible for surgery under general anaesthesia or refused surgical treatment. The efficacy of a daily single dose oral theophylline (5 - 7 mg/kg body weight, n = 30) and nCPAP ventilation (n = 30) was evaluated by apnea-hypopnea index (AHI) and Epworth Sleepiness Scale (ESS)...
