Two positions are in an upright sitting position and four positions are with the head tilted below the lungs. To obtain the head- down positions, the use of a pillow, a bean bag chair, or couch cushions work well. Percussion and vibration help loosen and mobilize secretions. If you choose to use your hands, the palm of your hand should be cupped to provide a pocket of air that cushions the percussion. Manual percussors have padding and velcro to allow self use.
Vibration is done at the end of the position.
After a big breath in, vibrate when the air is slowly blown out, for three big breaths. Each position requires proper placement for percussion and should be done for 3-5 minutes. A strong cough is encouraged after each position to remove the mucus. It is recommended that CPT be done before meals and bedtime. Your doctor will determine how often CPT is needed.
