Volume

This is the daily number of shares of a security that change hands between a buyer and a seller. Also known as volume traded. Also see Up volume and Down volume.

volume

The amount of trading sustained in a security or in the entire market during a given period. Especially heavy volume may indicate that important news has just been announced or is expected. See also average daily volume.

Volume.

Volume is the number of shares traded in a company's stock or in an entire market over a specified period, typically a day.

Unusual market activity, either higher or lower than average, is typically the result of some external event. But unusual activity in an individual stock reflects new information about that stock or the stock's sector.

From the pathophysiological point of view, the ventilation-associated injury will depend on the stress and tension to which the lung parenchyma is subjected as a result of tidal volume, respiratory rate, flow, inspiration time, PEEP, volume and recruitment manoeuvres.
These included blood pressure (BP) and heart rate (HR) by continuous electrocardiogram and BP monitoring, Fi[O.sub.2], PEEP, compliance, resistance, peak inspiratory pressure, respiratory rate (total breaths per minute (b/min) and spontaneous b/min), spontaneous minute volume, expiratory tidal volume and actual minute volume.
In a small retrospective study conducted in 12 patients with both subarachnoid hemorrhage and ARDS, a lung protective strategy (i.e., tidal volume of 5-8 ml/kg and PEEP of 10-15 cm [H.sub.2]O) was employed with resulting hypercapnia (pC[O.sub.2] of 50-60 mm Hg; Petridis et al., 2010).

Initially, participants were mechanically ventilated in the volume-induced mode, with a tidal volume of 8 ml per kilogram of body weight, inspiratory flow of 60 litres per minute (square wave), with hyperinflated cuff, positioned in a supine 30-degree head-up position, and underwent tracheal aspiration.
