A typical displacement ventilation system, such as one in an office space, supplies conditioned cold air from an air handling unit (AHU) through a low induction air diffuser. Diffuser types vary by applications. Diffusers can be located against a wall ("wall-mounted"), at the corner of a room ("corner-mounted"), or above the floor but not ...
In medicine, mechanical ventilation is a method to mechanically assist or replace spontaneous breathing . A breath by breath trigger, limit, cycling (TLC) classification of the common modes of ventilation. (V = ventilator; P = patient) [2] Mode. Trigger. Limit. I cycle. P cycle. Servo.
Rooftop HVAC unit with view of fresh-air intake vent Ventilation duct with outlet diffuser vent. These are installed throughout a building to move air in or out of rooms. In the middle is a damper to open and close the vent to allow more or less air to enter the space. The control circuit in a household HVAC installation.
Demand controlled ventilation. Demand controlled ventilation (DCV) is a feedback control method to maintain indoor air quality that automatically adjusts the ventilation rate provided to a space in response to changes in conditions such as occupant number or indoor pollutant concentration. The most common indoor pollutants monitored in DCV ...

Pulmonology. Ventilator-associated lung injury (VALI) is an acute lung injury that develops during mechanical ventilation and is termed ventilator-induced lung injury (VILI) if it can be proven that the mechanical ventilation caused the acute lung injury. In contrast, ventilator-associated lung injury (VALI) exists if the cause cannot be proven.
CRAFT stands for: Clearance limit, the end point of the clearance (usually, but not always, the destination airport) Route, the route that the flight is to follow as part of the clearance (often the route originally filed, although ATC may change this) Altitude, the initial altitude to be maintained by the flight, plus, in many cases, a time at ...
Crankcase ventilation system. A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past ...
