105. Erratic Heartbeat
Build the circuit, press the switch
(62) and see an erratic heartbeat.
106. Heart Failure and
Shock
Press the switch (62) and the heart
LED (69) will ash steadily. Press
the press switch (61) and the
heartbeat will fail. Touch the touch
plate (80) to simulate a shock that
makes the heart beat come back
on.
107. Simulating CPR
Turn ON the switch (62) and press
the press switch (61) to simulate a
heart failure. Tap the press switch
(61) every three seconds and watch
the blood being pushed through the
heart. This is the idea behind CPR
which stands for cardiopulmonary
resuscitation.
108. The Pacemaker
Replace the press switch (61) with the reed switch (83), place the magnet (7) on the reed switch (80) and turn ON the
switch (62). Tap the reed switch (80) with the magnet (7) if the heart is not beating. Place the magnet (7) back on the
reed switch (80) to simulate a pacemaker is activated. Notice how the heartbeat is now steady. You may have to adjust
the magnet to achieve desired effect.
