1. A method for modifying a bag valve mask (BVM) including a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask, said method comprising:
providing a pressure safety device (PSD) having a bag port and a mask fitting and a flow path from the bag port to the mask fitting; and
connecting the bag port and the mask fitting of the PSD to the bag connector and the mask connector of the BVM, respectively;
wherein the PSD is configured to impede breathing gas flow from the BVM to the breathing mask when a pressure or flow rate of the breathing gas entering the bag port of the PSD exceeds a maximum threshold value;
wherein the PSD comprises a deformable seal having an open position and a closed position, wherein the deformable seal is configured to deform to fully block the flow path in response to the pressure or flow rate exceeding the maximum threshold value.
