Treatment of sleep apnea-hypopnea syndrome (SAHS) by fixed continuous positive airway pressure (CPAP) requires an in-laboratory titration procedure to determine the effective pressure level (Peff ). We recently reported that one auto-CPAP machine can be used without titration study allowing Peff determination. The aim of this study was to evaluate the accuracy of an auto CPAP trial at home. A 1...

1271 CPAP Therapy for Patients with Acute Ischemic Stroke—Bravata et al In general, interventions aimed at improving post-stroke functioning are more effective the earlier they are delivered after symptom onset. Auto-titrating CPAP (auto-CPAP) senses airflow limitation and delivers pressure in response to apneas and hypopneas. Auto-CPAP is equally efficacious compared with fixed-pressure CPAP, ...

BACKGROUND Continuous positive airway pressure (CPAP) with fixed mask pressure is the current standard treatment for obstructive sleep apnoea (OSA). Auto-CPAP devices apply at any time the minimally required pressure to normalise breathing and may improve patient comfort and compliance. We present an open descriptive study of auto-CPAP treatment at home in patients previously managed with conve...

Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea (OSA), but compliance and variables involved in long-term CPAP adherence in females with OSA are unknown. We performed an observational study including all consecutive females diagnosed with CPAP who started CPAP treatment in two Spanish teaching hospitals between 1999 and 2007 and were followed-u...

STUDY OBJECTIVES To evaluate the relationship between sleep structure and continuous positive airway pressure (CPAP) delivered by an automatic CPAP (auto-CPAP) machine in patients with obstructive sleep apnea syndrome (OSAS). DESIGN Nocturnal polysomnography was performed during CPAP administration by an auto-CPAP machine (Autoset Clinical 1; ResMed; Sydney, Australia). SETTING Sleep-disord...

INTRODUCTION Continuous positive airway pressure (CPAP) is used in air ambulances to treat patients with impaired oxygenation. Differences in mechanical principles between CPAP devices may affect their performance at different ambient air pressures, as will occur in an air ambulance during flight. METHODS Two different CPAP systems, a threshold resistor device and a flow resistor device, at s...

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 ...

Subjective nasal obstruction is common among users of continuous positive airway pressure (CPAP). The aim of this study was to measure the acute effect of CPAP on nasal resistance and nasal symptoms in awake normal subjects. Twenty-four healthy CPAP-naive adults [8 men, 16 women; mean age 30 yr (SD 14)] underwent a randomized controlled crossover study comparing nasal CPAP (8 cmH(2)O) for 6 h o...

BACKGROUND Nasal CPAP is the most common respiratory support for neonates. Several factors are considered important for effective treatment, including leaks at the patient interface and the delivery of pressure-stable CPAP. Investigations of pressure stability during leaks should include both the change in the mean delivered CPAP and the pressure variation during each breath. The aim of this st...

Adherence to continuous positive airway pressure (CPAP) treatment for obstructive sleep apnoea (OSA) is a critical problem. Poor adherence (30-60%) to CPAP is widely recognized as a significant limiting factor in treating OSA, reducing the overall effectiveness of the treatment and leaving many OSA patients at heightened risk for co-morbid conditions, impaired function and quality of life. The ...
