Underground mine ventilation. Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NOx, SO2, methane, CO2 and CO) and to regulate temperature.
Normal ventilation means the patient receives a normal pressure or volume of gas while inspiring and also while expiring.Minute ventilation means the ventilator makes sure that the patient inspires and expires the particular minute volume set for the patient.
