Effectiveness of Auto-adjusted Continuous Positive Airway Pressure for Long-term Treatment of Sleep Apnea
Hypothesis: Computer controlled continuous positive airway pressure (autoCPAP) is equally effective in improving obstructive sleep apnea syndrome symptoms, breathing disturbances, objective vigilance, and it is cost-effective compared to conventional fixed continuous positive airway pressure.
1. To investigate whether computer controlled continuous positive airway pressure (autoCPAP) improves subjective sleepiness, quality of life, objective vigilance, and nocturnal respiration to a similar degree as conventional fixed continuous positive airway pressure in the initial phase of treatment and over the subsequent 2 years during home therapy
2. To investigate the cost of autoCPAP compared to fixed CPAP therapy

Medical and Biotech [MESH] Definitions
Sleep Apnea, Central
A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
Sleep Apnea Syndromes
Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
Sleep Disorders, Intrinsic
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
A sleep disorder of central nervous system origin characterized by prolonged nocturnal sleep and periods of daytime drowsiness. Affected individuals experience difficulty with awakening in the morning and may have associated sleep drunkenness, automatic behaviors, and memory disturbances. This condition differs from narcolepsy in that daytime sleep periods are longer, there is no association with CATAPLEXY, and the multiple sleep latency onset test does not record sleep-onset rapid eye movement sleep. (From Chokroverty, Sleep Disorders Medicine, 1994, pp319-20; Psychiatry Clin Neurosci 1998 Apr:52(2):125-129)
Dental Devices, Home Care
Devices used in the home by persons to maintain dental and periodontal health. The devices include toothbrushes, dental flosses, water irrigators, gingival stimulators, etc.
The main purpose of this study is to investigate if treatment of obstructive sleep apnea syndrome (OSAS) by continuous positive airway pressure (CPAP) given by a traditional CPAP device ad...
This study is designed to determine the effectiveness of two different CPAP devices. One a standard CPAP which has the ability to store comprehensive compliance and efficacy data and the s...
Comparison of automatic CPAP with fixed CPAP in patients with OSAS
The purpose of this study is to evaluate the associations of circadian variations, sleep architecture, hypertension and prostanoids in the patients with sleep apnea. In addition, the patie...
Background: In patients with obstructive sleep apnea, automatic continuous positive airway pressure machines (autoCPAP) are said to be capable of identifying various breathing abnormalitie...
BACKGROUND: The high efficacy of continuous positive airway pressure (CPAP) in treating obstructive sleep apnea (OSA) is limited by poor compliance often related to pressure intolerance. Mandibular ad...
OBJECTIVES: Obstructive sleep apnea (OSA) is associated with significant cardiovascular (CV) morbidity. Continuous positive airway pressure (CPAP) is the standard treatment for moderate to severe OSA,...
PURPOSE: Although continuous positive airway pressure (CPAP) is the gold standard in the treatment of obstructive sleep apnea (OSA), its effectiveness depends on the regular use. In this retrospective...
Treatment of obstructive sleep apnea (OSA) by continuous positive airway pressure (CPAP) usually causes a reduction in blood pressure (BP), but several factors may interfere with its effects. In addit...
BACKGROUND: Continuous positive airway pressure (CPAP) is the elective treatment of obstructive sleep apnea. The therapeutic level of CPAP is generally established by manual titration or an auto CPAP...
