Abstract
An MIE apparatus has a blower, a valve system, and a mask hose connector. The blower is connected to the valve system which is connected to the hose connector. During insufflation, the valve system connects exhaust of the blower to the hose connector to cause positive pressure at the hose connector. During exsufflation, the valve system connects the blower intake to the hose connector to cause negative pressure at the hose connector. The apparatus has an automatic mode in which switching between insufflation and exsufflation is based on one or more preset time intervals and a manual mode in which switching between insufflation and exsufflation is based on a manual input from a user.
