An incentive Spirometer is a device that increases pulmonary function, and also clears Secretions of the air pathway. It reduces Postoperative Pulmonary Complications. It also stimulates cough. It will give Visual Feedback to the Patient and encourages the Patient.

2. INCENTIVE SPIROMETRY
• INCENTIVE SPIROMETERS ARE MECHANICAL
DEVICES INTRODUCED IN AN ATTEMPT TO
REDUCE POSTOPERATIVE PULMONARY
COMPLICATIONS.
• THE PATIENT TAKES A SLOW DEEP BREATH IN,
WITH HIS LIPS SEALED AROUND THE MOUTHPIECE
AND IS MOTIVATED BY VISUAL FEEDBACK, FOR
EXAMPLE A BALL RISING TO A PRESET MARKER
(600CC, 900CC & 1200CC).
• THE PATIENT AIMS TO GENERATE A
PREDETERMINED FLOW OR TO ACHIEVE A PRESET
VOLUME AND HE IS ENCOURAGED TO HOLD HIS
BREATH FOR 2-3 SECONDS AT FULL INSPIRATION,

3. • A SHORT SHARP INSPIRATION CAN ACTIVATE THE
FLOW-GENERATED INCENTIVE SPIROMETRY
DEVICES WITH LITTLE INCREASE IN TIDAL
VOLUME, BUT WITH A VOLUME-DEPENDENT
DEVICE AN INCREASE IN TIDAL VOLUME MUST BE
ACHIEVED BEFORE THE PRESET LEVEL CAN BE
REACHED.
• THE PATTERN OF BREATHING WHILE USING AN
INCENTIVE SPIROMETER IS IMPORTANT,
EXPANSION OF THE LOWER CHEST SHOULD BE
EMPHASIZED RATHER THAN THE USE OF THE
ACCESSORY MUSCLES OF RESPIRATION

4. • DIAPHRAGMATIC MOVEMENT IS THOUGHT TO BE
AN IMPORTANT FACTOR IN THE PREVENTION OF
POSTOPERATIVE PULMONARY COMPLICATIONS.
• INCENTIVE SPIROMETRY HAS BEEN SHOWN TO
INCREASE ABDOMINAL MOVEMENT IN NORMAL
SUBJECTS, BUT NOT IN SUBJECTS FOLLOWING
ABDOMINAL SURGERY.
• POSTOPERATIVELY, AN INCREASE IN
DIAPHRAGMATIC MOVEMENT HAS BEEN
OBSERVED BY ENCOURAGING, AN INCREASE IN
LUNG VOLUME WHILE USING THE PATTERN OF
BREATHING CONTROL WITHOUT THE RESISTIVE
LOADING OF AN INCENTIVE SPIROMETER

5. • THIS MAY HELP TO REDUCE POSTOPERATIVE
PULMONARY COMPLICATIONS BY INCREASING
VENTILATION TO THE DEPENDENT PARTS OF
THE LUNGS.
• INCENTIVE SPIROMETRY HAS BEEN COMPARED
WITH INTERMITTENT POSITIVE PRESSURE
BREATHING, CONTINUOUS POSITIVE AIRWAY
PRESSURE AND CHEST PHYSIOTHERAPY IN
PATIENTS FOLLOWING SURGERY. FEW
DIFFERENCES BETWEEN THE REGIMENS HAVE
BEEN REPORTED.

6. • THERE MAY BE A PLACE FOR THE USE OF
INCENTIVE SPIROMETRY IN CHILDREN AND IN
SOME ADOLESCENTS TO PROVIDE MOTIVATION
TO INCREASE LUNG VOLUME FOLLOWING
SURGERY, BUT THE USE OF BREATHING
CONTROL AND THORACIC EXPANSION
EXERCISES WITH AN INSPIRATORY HOLD
SHOULD BE ENCOURAGED, AND COMBINED
WITH AMBULATION MAY BE MORE EFFECTIVE IN
THE PREVENTION OF POSTOPERATIVE
PULMONARY COMPLICATIONS
