An accurate ambulatory breathing monitor is needed to observe acute respiratory changes
in patients with medical or psychological disorders outside the clinic (eg, hyperventilation …

The main aim of this handbook is to provide a comprehensive, authoritative, and practical
account of human factors and ergonomics methods. It is intended to encourage people to …

Swallowing occurs preferentially in the expiratory phase of the quiet breathing cycle and at
mid-to-low tidal volume. This coordinative pattern imparts important biomechanical …

Objective To test a novel intervention to train swallowing to occur in the midexpiratory to low
expiratory phase of quiet breathing to improve swallowing safety and efficiency. Design …

Previous studies have demonstrated that lung volume during wakefulness influences upper
airway size and resistance, particularly in patients with sleep apnea. We sought to determine …

Abstract Study Objectives: Previous studies in both awake and sleeping humans have
demonstrated that lung-volume changes substantially affect upperairway size and …

During swallowing, the airway is protected from aspiration of ingested material by brief
closure of the larynx and cessation of breathing. Mechanoreceptors innervated by the …

Background: Previous studies have shown that changes in lung volume influence upper
airway size and resistance, particularly in patients with obstructive sleep apnoea (OSA), and …

Changes in end-expiratory lung volume (EELV) affect upper airway stability. The passive
pharyngeal critical pressure (Pcrit), a measure of upper airway collapsibility, is determined …

Background: Measurements in absolute terms of the whole respiratory movement pattern
(range, type, symmetry, rhythm and frequency of breathing movements) of healthy …
