Keep the fingers of the other hand flexed and the wrist loose (figure 2-7).
Figure 2-7. Hand position.
(3) With the tip of the middle finger of the flexed hand, strike the first joint of
the middle finger of the hand that is on the patient's chest (figure 2-8). Have the motion
come from the wrist.
Figure 2-8. Striking position.
Withdraw the striking finger immediately to avoid damping the vibration.
(5) Strike once or twice, then move your hands symmetrically to another
part of the chest.
b. Areas of Percussion.
(1) Ideally, the patient should lie in the supine position (lying on the back,
face upward) for percussion on the front of the chest. The patient should be sitting up
for percussion on the back.
