Increase in upper airway resistance is the main patho-physiological feature in the
obstructive breathing disorders during sleep. Upper airway events may be divided into two …

Sleep breathing disorders (SBD) are related to obstructions resulting from repetitive
narrowing and closure of the pharyngeal airway. Their diagnoses and treatment are critically …

The sleep apnoea–hypopnoea syndrome is characterised by recurrent obstructions of the
upper airway, resulting in sleep disruption and arterial oxygen desaturations. Noninvasive …

Obstructive sleep apnea, which is the most prevalent sleep breathing disorder, is
characterized by recurrent episodes of upper airway collapse and reopening. However, the …

The forced oscillation technique (FOT) is a noninvasive method that is useful for assessing
airway obstruction and for titrating continuous positive airway pressure (CPAP) in patients …

Background: A study was undertaken to examine the expiratory flow response to a negative
pressure (NEP) applied at the airway in patients with no abnormalities of the intrathoracic …

The forced oscillation technique (FOT) is a noninvasive method of potential clinical interest
for quantitatively assessing airway mechanics during sleep. We investigated the applicability …

The forced oscillation technique (FOT) is a non-invasive method which may be suitable for
assessing upper airway obstruction in obstructive sleep apnea/hypopnea syndrome (OSAS) …

Sleep breathing disorders are estimated to be present in 2%–4% of middle-aged adults.
Serious adverse consequences, such as systemic arterial hypertension, myocardial …

Assessment of upper airway mechanics in patients with obstructive sleep apnea/hypopnea
(OSA) can be carried out qualitatively from indirect signals (flow pattern, snoring, strain …
