The Prapela pad 

Pacemaker neurons found in the lower brainstem, the "oldest" region of the brain, are responsible for breathing and heart rates. Science explains how stochastic stimulation propels neurons helping stabilize dysregulated breathing and heart rates

Prapela stimulation is the most precisely controlled stochastic vibration for infant health in the world.   Our vibration moves up and down less than half the diameter of a human hair at a speed difficult to sense.  These tiny movements require less than 5 volts of electricity, an amount so low it can not cause a shock.  The Prapela SVS hospital bassinet pad is certified by SGS to ANSI 60601-1 Electrical Safety Standards and meets the IEC/EN 60529 standard of IPX5 protection from ingress.
