\nAARC Clinical Practice Guideline
\nPostural Drainage Therapy
\nPDT 1.0 PROCEDURE:
\nPostural drainage therapy (PDT) is a component of bronchial hygiene therapy. It consists of postural drainage, positioning, and turning and is sometimes accompanied by chest percussion and\/or vibration.
\nCough or airway clearance techniques are essential components of therapy when postural drainage is intended to mobilize secretions.(1-6) Postural drainage therapy is often used in conjunction with aerosol administration and other respiratory care procedures.
\nThis procedure has been commonly referred to as(7-12)
\nchest physiotherapy,
\nchest physical therapy,
\npostural drainage and percussion, and
\npercussion and vibration.
\nPDT 2.0 DESCRIPTION\/DEFINITION:
\nPostural drainage therapy is designed to improve the mobilization of bronchial secretions(2,4,5,8-10,13-18) and the matching of ventilation and perfusion,(19-23) and to normalize functional residual capacity (FRC)(17,24-30) based on the effects of gravity and external manipulation of the thorax. This includes turning, postural drainage, percussion, vibration, and cough.
\n2.1 Turning
\nTurning is the rotation of the body around the longitudinal axis to promote unilateral or bilateral lung expansion(19,22) and improve arterial oxygenation.(19-21,31) Regular turning can be to either side or the prone position,(32) with the bed at any degree of inclination (as indicated and tolerated). Patients may turn themselves or they may turned by the caregiver or by a special bed or device.(21,22,33-35)
\n2.2 Postural Drainage
\nPostural drainage is the drainage of secretions, by the effect of gravity, from one or more lung segments to the central airways (where they can be removed by cough or mechanical aspiration).(2,4,5,11,13,15-18,26,29,36,37) Each position consists of placing the target lung segment(s) superior to the carina. Positions should generally be held for 3 to 15 minutes (longer in special situations).(4,6,13,16,18,20,29,38-40) Standard positions are modified as the patient’s condition and tolerance warrant.
\n2.3 External Manipulation of the Thorax
\n2.3.1 Percussion
\nPercussion is also referred to as cupping, clapping, and tapotement. The purpose of percussion is to intermittently apply kinetic energy to the chest wall and lung. This is accomplished by rhythmically striking the thorax with cupped hand or mechanical device directly over the lung segment(s) being drained. No convincing evidence demonstrates the superiority of one method over the other.(4,18,41-44)
\n2.3.2 Vibration
\nVibration involves the application of a fine tremorous action (manually performed by pressing in the direction that the ribs and soft tissue of the chest move during expiration) over the draining area. No conclusive evidence supports the efficacy of vibration, the superiority of either manual or mechanical methods, or an optimum frequency.(2,4,13,27,28,30,36,38,39,45-47)
\nPDT 3.0 SETTING:
\nAlthough PDT can be used with neonates, infants, childrens, and adults, this Guideline applies primarily to older children and adults. PDT can be performed in a wide variety of settings.

\n5.2.3 recent skin grafts, or flaps, on the thorax
\n5.2.4 burns, open wounds, and skin infections of the thorax

\nPDT 6.0 HAZARDS\/COMPLICATIONS:
\n6.1 Hypoxemia
\nAction To Be Taken\/Possible Intervention: Administer higher oxygen concentrations during procedure if potential for or observed hypoxemia exists. If patient becomes hypoxemic during treatment, administer 100% oxygen, stop therapy immediately, return patient to original resting position, and consult physician. Ensure adequate ventilation. Hypoxemia during postural drainage may be avoided in unilateral lung disease by placing the involved lung up-permost with patient on his or her side.(20,22,48-50)
\n6.2 Increased Intracranial Pressure
\nAction To Be Taken\/Possible Intervention: Stop therapy, return patient to original resting position, and consult physician.
\n6.3 Acute Hypotension during Procedure
\nAction To Be Taken\/Possible Intervention: Stop therapy, return patient to original resting position, and consult physician.
\n6.4 Pulmonary Hemorrhage
\nAction To Be Taken\/Possible Intervention: Stop therapy, return patient to original resting position, call physician immediately. Administer oxygen and maintain an airway until
\nphysician responds.
\n6.5 Pain or Injury to Muscles, Ribs, or Spine
\nAction To Be Taken\/Possible Intervention: Stop therapy that appears directly associated with pain or problem, exercise care in moving patient, and consult physician.
\n6.6 Vomiting and Aspiration
\nAction To Be Taken\/Possible Intervention: Stop therapy, clear airway and suction as needed, administer oxygen, maintain airway, return patient to previous resting position, and contact physician immediately.
\n6.7 Bronchospasm
\nAction To Be Taken\/Possible Intervention: Stop therapy, return patient to previous resting position, administer or increase oxygen delivery while contacting physician. Administer physician-ordered bronchodilators.
\n6.8 Dysrhythmias
\nAction To Be Taken\/Possible Intervention: Stop therapy, return patient to previous resting position, administer or increase oxygen delivery while contacting physician.
\nPDT 7.0 LIMITATIONS OF METHOD:
\n7.1 Presumed effectiveness of PDT and its application may be based more on tradition and anecdotal report than on scientific evidence. The procedure has been used excessively and in patients in whom it is not indicated.(11,40,61-63)
\n7.2 Airway clearance may be less than optimal in patients with ineffective cough.
\n7.3 Optimal positioning is difficult in critically ill patients.
\nPDT 8.0 ASSESSMENT OF NEED:
\nThe following should be assessed together to establish a need for postural drainage therapy
\n8.1 excessive sputum production
\n8.2 effectiveness of cough
\n8.3 history of pulmonary problems treated successfully with PDT (eg, bronchiectasis, cystic fibrosis, lung abscess)
\n8.4 decreased breath sounds or crackles or rhonchi suggesting secretions in the airway
\n8.5 change in vital signs
\n8.6 Abnormal chest x-ray consistent with atelectasis, mucus plugging, or infiltrates
\n8.7 deterioration in arterial blood gas values or oxygen saturation
\nPDT 9.0 ASSESSMENT OF OUTCOME:
\nThese represent individual criteria that indicate a positive response to therapy (and support continuation of therapy). Not all criteria are required to justify continuation of therapy (eg, a ventilated patient may not have sputum production > 30 mL\/day, but have improvement in breath sounds, chest x-ray, or increased compliance or decreased resistance).
\n9.1 Change in sputum production
\nIf sputum production in an optimally hydrated patient is less than 25 mL\/day with PDT the procedure is not justified.(3,5,7,9,11,12,38,40,46,51-53) Some patients have productive coughs with sputum production from 15 to 30 mL\/day (occasionally as high as 70 or 100 mL\/day) without postural drainage. If postural drainage does not increase sputum in a patient who produces > 30 mL\/day of sputum without postural drainage, the continuation of the therapy is not indicated. Because sputum production is affected by systemic hydration, apparently ineffective PDT probably should be continued for at least 24 hours after optimal hydration has been judged to be present.
\n9.2 Change in breath sounds of lung fields being drained
\nWith effective therapy, breath sounds may ‘worsen’ following the therapy as secretions move into the larger airways and increase rhonchi. An increase in adventitious breath sounds can be a marked improvement over absent or diminished breath sounds. Note any effect that coughing may have on breath sounds. One of the favorable effects of coughing is clearing of adventitious breath sounds.
\n9.3 Patient subjective response to therapy
\nThe caregiver should ask patient how he or she feels before, during, and after therapy. Feelings of pain, discomfort, shortness of breath, dizziness, and nausea should be considered in decisions to modify or stop therapy. Easier clearance of secretions and increased volume of secretions during and after treatments support continuation.
\n9.4 Change in vital signs
\nModerate changes in respiratory rate and\/or pulse rate are expected. Bradycardia, tachycardia, or an increase in irregularity of pulse, or fall or dramatic increase in blood pressure are indications for stopping therapy.
\n9.5 Change in chest x-ray
\nResolution or improvement of atelectasis may be slow or dramatic.
\n9.6 Change in arterial blood gas values or oxygen saturation
\nOxygenation should improve as atelectasis resolves.
\n9.7 Change in ventilator variables
\nResolution of atelectasis and plugging reduces resistance and increases compliance.

It consists of postural drainage, positioning, and turning and is sometimes accompanied by chest percussion and\/or vibration. Cough or airway clearance techniques are essential components of therapy<\/p>\n
