A facial mask includes a mask body that is adapted to be coupled to a
patient's face. A valve system is coupled to the mask body to permit the
inflow of respiratory gasses into the mask body and to permit the outflow
of respiratory gasses from the mask body. A metronome is coupled to the
mask body to produce a repeating chest compression signal to facilitate
the performance of regular chest compressions when performing cardio
pulmonary resuscitation. The metronome may also produce a ventilation
signal to facilitate the proper ventilation of the patient.
