MANUAL RESUSCITATOR, VENTILATION CONTROL ASSEMBLY, AND METHOD OF USE

Manual resuscitators, ventilation control assemblies, and methods suitable for delivering a volume-controlled tidal volume of air to a patient's lungs. Such a resuscitator has a piston that pushes a selected volume of air out of a ventilation chamber of a cylinder in response to pressurized gases being introduced into an actuation chamber of the cylinder. A volume adjuster adjusts the maximum tidal volume of patient air that the piston pushes out of the ventilation chamber by adjusting the maximum length of the piston stroke in the cylinder. The volume adjuster may have a bypass mode that allows the manual resuscitator to operate without volume control. The manual adjuster may also be pressure regulated by one or more pressure regulation valves.
