| high-frequency ventilation | Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (hfppv), high-frequency jet ventilation (hfjv), and high-frequency oscillation (hfo). (12 Dec 1998) |
|---|---|
| pulmonary ventilation | The process of exchange of air between the lungs and the ambient air. Pulmonary ventilation is a measure of the rate of ventilation expressed usually in liters per minute. (12 Dec 1998) |
| spontaneous intermittent mandatory ventilation | Intermittent mandatory ventilation spontaneously initiated by the patient, to increase tidal volume, and subsequently synchronised with patient's respiratory cycle. Synonym: synchronised intermittent mandatory ventilation. (05 Mar 2000) |
| synchronised intermittent mandatory ventilation | Intermittent mandatory ventilation spontaneously initiated by the patient, to increase tidal volume, and subsequently synchronised with patient's respiratory cycle. Synonym: synchronised intermittent mandatory ventilation. (05 Mar 2000) |
| intermittent mandatory ventilation | Mechanical application of positive pressure at a predetermined frequency to the airway to increase tidal volume. (05 Mar 2000) |
| intermittent positive-pressure ventilation | Application of positive pressure to the inspiratory phase when the patient has an artificial airway in place and is connected to a ventilator. See: controlled mechanical ventilation (12 Dec 1998) |
| lung ventilation agents | <radiology> Xe-133, most commonly used, Xe-127, t = 36.4 days; photons @ 172, 203, 375 keV, can image V after Q, Kr-81m, very expensive, t = 13 sec; photon 190 keV, can repeat V in each projection, Tc-99m DTPA aerosol, can image V in mult. Projections, image Q after V, 1 mCi most likely to be 50-75 mrad to lung, V/Q imaging (12 Dec 1998) |

| ventilation rate |
The rate at which indoor air enters and leaves a building. Expressed as the number of changes of outdoor air per unit of time (air changes per hour (ACH), or the rate at which a volume of outdoor air enters in cubic feet per minute (CFM).

| ventilation |
Ventilation is the movement of air. One of the main purposes of ventilation is to remove contaminated air from the workplace. There are several different kinds of ventilation. (See General Ventilation, Local Exhaust Ventilation, Mechanical Ventilation and Natural Ventilation.)
