Portable ventilation devices and systems

Abstract

A portable ventilation system (100) can have a ventilation mask. The ventilation mask includes a mask body (102) having an outer surface (106) and an inner surface (108) configured for engagement with a face of a subject. The mask body (102) defines an inlet opening (110) configured to receive an airflow. The ventilation system (100) further includes a blower assembly (112) positioned in fluid communication with the inlet opening (110) of the mask body (102) to direct the airflow to the inlet opening (110). A breath delivery mechanism (104a-b), that when manually operated, activates the blower assembly (112) and delivers a breath to the subject by increasing a pressure within the ventilation mask.
