Positive airway pressure (PAP) and upper airway stimulation (UAS) are approved obstructive sleep apnea (OSA) treatment options.. Although the effect of PAP on improvement in blood pressure (BP) and daytime sleepiness (defined by Epworth Sleepiness Scale, ESS) has been established, the impact of UAS on BP remains unclear. We hypothesize that PAP and UAS will confer improvements in BP and daytime sleepiness.

Examine the patient characteristics of those undergoing upper airway stimulation (UAS) for the treatment of continuous positive airway pressure (CPAP)-refractive obstructive sleep apnea (OSA) at a ter...
Pediatric airway disorders may be congenital (anatomical) or acquired (infectious) and may involve the upper, lower, or entire airway, with obstruction being a common feature. The pathophysiology of u...
Upper airway stimulation plays an increasingly important role in the treatment of obstructive sleep apnea (OSA). The target of stimulation is the hypoglossal nerve (N. XII), which-as a pure motor ne...

A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit.

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator.
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (POSITIVE-PRESSURE RESPIRATION). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-PEEP may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode.
