Witryna1 wrz 2024 · The imposed work of breathing during high-frequency oscillatory ventilation (HFOV) while allowing the patient to breathe spontaneously is greater for pediatric and adult patients than for newborns and infants. Work of breathing (WOB) is the energy expended to inhale and exhale a breathing gas. It is usually expressed as work per unit volume, for example, joules/litre, or as a work rate (power), such as joules/min or equivalent units, as it is not particularly useful without a reference to volume or time. It can be calculated in … Zobacz więcej The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. Some of this work is to overcome frictional resistance to … Zobacz więcej Work is defined as a force applied over a distance.
