Historically, brief awakenings from sleep (cortical arousals) have been assumed to be vitally
important in restoring airflow and blood-gas disturbances at the end of obstructive sleep …

Positive airway pressure (PAP) devices are used to treat patients with sleep related
breathing disorders (SRBDs), including obstructive sleep apnea (OSA). After a patient is …

Nasal continuous positive airway pressure (CPAP) is a highly effective treatment for
obstructive sleep apnea syndrome. The apnea/hypopnea index (AHI) is reduced 10-fold, but …

Current evidence suggests that patients with obstructive sleep apnea (OSA) may have
greater pharyngeal critical pressure (Pcrit), which reflects the increase in upper airway …

Background Anesthetic agents inhibit the respiratory activity of upper airway muscles more
than the diaphragm, creating a potential for narrowing or complete closure of the pharyngeal …

Esophageal pressure (Pes) monitoring can be performed during polysomnography with a
thin, water-filled catheter connected to a transducer. The resulting quantitative assessment …

Obstructive sleep apnea syndrome (OSAS) is a process that is associated with the
development of arterial hypertension, the main risk factor for aortic dissection and during …

To define the standard of airway flow limitation, pharyngeal pressure and flow rate were
measured during wakefulness and sleep in seven habitual snorers with widely varying …

Objective To evaluate the patients' individual characteristics predictive of the degree of
respiratory effort developed during obstructive sleep apneas (OSAs). Design Prospective …

Study Objectives: Mandibular advancement splints (MAS) are often preferred to CPAP
treatment for OSA but are not always equally efficacious. High therapeutic CPAP pressure …
