chest pt techniques

1. Pediatric chest physiotherapy
management

2. Definition.
• Chest physiotherapy (CPT) is an airway clearance technique
that combines manual percussion of the chest wall by the care-
giver, strategic positioning of the patient for mucus drainage
with cough and breathing techniques.
• It is useful for individuals with copious mucus or thick
secretions, those with weak respiratory mechanics or those with
ineffective cough.

4. What does it consist of ?
CPT consists of various manipulative procedures like
• positioning
• chest percussion
• vibration
• thoracic squeezing
• cough stimulation.
• Breathing exercise is an integral part of chest physiotherapy. It
plays a significant role in airway clearance and parenchymal
expansion by improving the efficiency of respiratory muscles.

5. Postural Drainage (Positioning)
• Postural drainage prevents the accumulation and enhances
mobilization of bronchial secretion from the airway utilizing gravity to
facilitate drainage.
• Postural drainage is mere positioning of the child with assistance of
gravity to mobilize the secretions towards the main bronchus.
• Mere tilting of the thorax does not effectively clear the airway
secretions, but if complemented by deep breathing, effective coughing,
percussion and vibration techniques would loosen and dislodge these
secretions.

6. Rationale behind Postural Drainage
• During erect position only the segments of the right upper lobe and
non-lingular portion of the left upper lobe receive gravitational
assistance whereas the segment of the middle, lingular portion of left
upper lobe and lower lobe segments of both lungs must drain
against gravity.
• In normal healthy state the adequate patency of the tracheobronchial
tree and the effective function of the mucociliary mechanism clear off
the bronchial secretion inspite of these disadvantages.
• In diseased state they get compromised and secretions get
accumulated especially in the smaller airways that cannot be
emptied without gravity assistance.

7. Upper Lobe:
Apical bronchus * - Sitting upright with slight variation according to the position of
the lesion, i.e. slightly leaning backwards, forwards or sideways. (a)
Anterior bronchus * - Lying supine with the knees slightly flexed. (c)
Posterior bronchus:
Right - Lying on the left side and turn his face 45º resting against a pillow, with
another pillow supporting the head. (f)
Left - Lying on the right side turning his/her face 45º with 3 pillows arranged to lift the
shoulders by 12 inches. (b)

maintained by a pillow under the right side from shoulder to hip and foot end raised by
14 inches (35 cms). (d)

8. Chest percussion.
• Depending on the available area, the therapist can use single or both cupped hands or 3
fingers with the middle finger tented or a facemask with either the port covered or
occluded by a finger and strike repeatedly at a rate of 3 per second over that part of the
bronchopulmonary segment which needs to be drained.
• The cupped hand/mask tends to trap a cushion of air, which softens the blow while
striking, and the air column inside the cupped hand causes effective dislodgement of the
secretions in the underlying bronchus as the compression wave is presumably transmitted
to the underlying bronchus and gravitational aid causes flow of secretions from the
bronchus towards the glottis.
• The movement should be only at the wrist without causing pain or discomfort and can be
done throughout inspiration and expiration.
• Rings should be removed before percussion.
• Percussion should be vigorous but not painful and should not be done on bare skin, but
over soft comfortable clothing or towels.
• Properly done percussion produces only sound rather than discomfort which the child gets
used to in due course.
• Mechanical percussors are also available and maybe useful in adolescents.

9. Vibration
• In this a rapid vibratory impulse is transmitted
through the chest wall from the flattened hands
of the therapist by isometric alternate contraction
of forearm flexor and extensor muscles, to
loosen and dislodge the airway secretions.
• Vibration is a technical procedure and is usually
effectively executed only by a physiotherapist.

10. Thoracic Squeezing.
• The expiratory phase is reinforced in
this maneuver.
• The child is asked to take a deep
breath and then exhale through the
mouth as completely and rapidly as
possible, as would be done for a forced
expiratory volume determination.
• The depth of the expiration is increased
by brief firm pressure from the
operator’s hand compressing the sides
of the thorax (thoracic squeeze). This is
usually done by physiotherapist.

11. Cough stimulation
• Child can be requested to cough. In uncooperative or small children tracheal
stimulation or tickling can be done by placing index finger or thumb on anterior
side of the neck against trachea just above sternal notch with gentle but firm
inward pressure in circular pattern as the child begins to exhale.
• In certain diseases with respiratory involvement the child may have feeble or
ineffective cough and cough reinforcement is of much help in such conditions.
• Here the child should be advised to cough out while the hand of the operator
reinforces anticipated cough by synchronously compressing the lower half of the
chest.
• The sputum may be collected in a container to quantify or demonstrate to the
child and their parents.
• In small infants and children a bulb sucker can be used to clear the oral and nasal
secretions.
• For home therapy, postural drainage with cupped hand percussion with cough
reinforcement and suctioning or clearing the retained nasal and oral secretions is
advised.

12. Manual Hyperinflation
• Manual Hyperinflation The aims of manual hyperinflation
are to enhance mobilization of secretions by increasing
expiratory flow, re-inflate atelectatic areas, and improve
gas exchange.
• The technique involves disconnecting the patient from
mechanical ventilation to provide temporary manual
ventilation.
• Patients receive normal tidal volumes coupled with an
increased tidal volume using a 500mL infant bag (or a 1L
bag for older children).
• A manometer is applied to the circuit to monitor
pressures. As a general guide, manual hyperinflation
ventilation pressures should not exceed 10cmH2O above
the ventilator pressure.
• Flow rates of gas should be adjusted according to the
child: 4L/min for infants, increasing to 8L/min for children.
• Contraindications and precautions: Hemodynamic
instability, undrained pneumothorax, severe cystic or
bullous lung disease, severe bronchospasm, High PEEP.

13. INCENTIVE SPIROMETER.
• Incentive Spirometry (IS) Incentive spirometry
is designed to mimic natural sighing or yawning
by encouraging the patient to take long, slow,
deep breaths.
• This is accomplished by using a device that
provides patients with visual or other positive
feedback when they inhale at a predetermined
flow rate or volume and sustain the inflation for
a minimum of 3 seconds.
• The aim of this maneuver is to open up
atelectatic areas and improve lung volumes with
visual feedback.
• Precautions: Children with ventilatory failure.

14. Breathing exercise.
• Breathing exercises are meant to increase the breathing
efficiency and functional tidal volume.
• It is a component of airway clearance therapy in CPT and is
also used for pulmonary rehabilitation.
• Breathing exercise increases the diameter of airway above that
of normal tidal volume and helps to loosen and dislodge
bronchial secretion.
• This prevents alveolar collapse, facilitates lung expansion and
peripheral airway clearance.

15. Active Cycle of Breathing Techniques (ACBT)
• ACBT has been shown to be effective to clear bronchial secretions and to improve lung function without causing
hypoxemia.
• The technique consists of
- (1) breathing control (BC), which is a resting period of gentle relaxed breathing at the patient's own rate and depth
- (2) thoracic expansion exercises (TEE), which are 3 to 5 deep breaths emphasizing inspiration
- (3) forced expiration technique (FET, or “huff”), which combines 1 to 2 forced expirations followed by a period of
BC.
The technique is flexible and can be performed in any position. It can be adapted for young children into blowing games.
The patient carries out cycles of BC, TEE, BC, and FET. If the secretions are in the lower airways, the cycle will incorporate
more cycles of TEE and BC.

16. Flutter
• Flutter This device combines an oscillation of the air within the
airways during expiration.
• It consists of a small plastic pipe with a high-density ball
enclosed in a small cone. Breathing through the pipe and
against the ball creates positive expiratory pressure and
oscillation within the airways.
• The flutter device requires correct positioning in order to get
maximum vibrations.
• The device can be used with the patient in the lying or sitting
position and has been shown to decrease sputum viscosity.
• Usually patients will perform 4 to 8 deep breaths followed by
a forced expiration.
• Contraindications and Precautions: Hemodynamic instability,
pneumothorax, severe bronchospasm.

17. Positive expiratory pressure

18. Intermittent Positive Pressure Breathing (IPPB)
• IPPB has been shown to augment tidal volume by
delivering positive pressure via a mouthpiece or mask.
• By increasing tidal volumes, this device utilizes collateral
ventilation and gets air behind secretions to mobilize
them.
• IPPB has been shown to help with clearance of secretions
when simpler airway clearance techniques are not
maximally effective (e.g., patients who are fatiguing and
have chronic sputum retention, postoperative patients, or
patients with neuromuscular disease who are unable to
take a deep breath).
Precautions: Oxygen-sensitive patients, postoperative air
leak, hemodynamic instability, pneumothorax, lung abscess,
bronchial tumors, and severe bronchospasm

19. Autogenic Drainage
• AD aims to maximize air flow within the airways, improve
ventilation, and clear secretions.
• AD utilizes gentle breathing at different lung volumes to loosen,
mobilize, and clear bronchial secretions.
• The patient breathes in and holds his or her breath for 2 to 4
seconds (the hold facilitates equal filling of the lung segments).
• Expiration is performed keeping the upper airways open (as if
sighing).
• The expiratory force is balanced so that the expiratory flow reaches
the highest rate possible without causing airway compression.
• This cycle is repeated at different lung volumes, while collecting
secretions from the peripheral airways and moving them toward the
mouth.
• Patients need to have a good understanding of the technique, and
their lungs to be able to move the secretions effectively.

21. Suctioning.
• Nasal Pharyngeal and Oral Suction
• If the child is unable to clear secretions with the airway
clearance techniques previously described, nasopharyngeal
or oropharyngeal suctioning may be indicated.
• Nasopharyngeal suctioning is required in children until
they are old enough to cough voluntarily and effectively.
• Nasopharyngeal suctioning uses an appropriate-size
catheter, and it is an unpleasant experience.
• Prior to suctioning, the patient must be adequately
oxygenated. Supplemental oxygen should be available
during the procedure.
• If secretions have collected at the back of the throat, oral
suction to the back of the mouth may be sufficient.
• Precautions: Raised intracranial pressure, epistaxis,
craniofacial abnormality, severe bronchospasm, and stridor.

22. Breathlessness management.
• To be taught BC, the patient should be in a comfortable, well-
supported position either sitting or in high side lying
• The patient is encouraged to relax the upper chest, shoulders and
arms.
• One hand, which may be either the patient’s or the
physiotherapist’s or one hand of each, can be positioned lightly
on the upper abdomen.
• As the patient breathes in, the hand should be felt to rise up and
out; as the patient breathes out, the hand sinks down and in.
• Inspiration using the lower chest in this way is the active phase.
• Expiration should be relaxed and passive, and both inspiration
and expiration should be barely audible.
• Inspiration through the nose allows the air to be warmed,
humidified and altered before it reaches the upper airways.
• If the nose is blocked, breathing through the mouth will reduce
the resistance to the ow of air and reduce the work of breathing. If
the patient is very breathless, breathing through the mouth will
reduce the anatomical dead space.

23. INDICATIONS OF CPT.
• Bronchiectasis
• Cystic fibrosis (CF).
• With thick mucus secretion leading on to segmental lesions/collapse.
• In children with weak respiratory mechanics like cerebral palsy and neuro-
muscular disorders e.g., spinal muscular atrophy.
• In children with weak cough like vocal cord palsy, brain stem lesion.
• In kyphoscoliosis the lung function is restricted by decreased chest wall
compliance and can result in unequal lung expansion
• In bedridden children, immobilization may limit or prevent physical exercise,
impairing their ability to maintain aerobic capacity and lung volume
• Bronchiolitis
• Pneumonia
• In intensive care unit (ICU), CPT is the treatment of choice only for patients with
acute lobar atelectasis. Prone positioning improves oxygenation in some patients
with severe acute respiratory failure or ARDS.
