BAROTRAUMA AND VOLUTRAUMA PREVENTION DEVICE

摘要

An embodiment in accordance with the present invention provides a monitor for use with a bag valve mask (BVM). In some embodiments, the monitor can take the form of an inline electronic spirometer using a bi-directional digital turbine for the BVM with volume, pressure, and respiratory rate alarms and active real time monitoring in order to prevent volutrauma/barotrauma and hypoxia. Alternatively, an out of line electronic spirometer using a variable orifice or fixed orifice flowmeter (pitot tube) and two tubes connected to a portable device can be used. The monitor can come with a BVM or can be a separate device configured for coupling to an existing BVM.
