Chest Physiotherapy: Nursing Airway Clearance Steps & Safety Guide
On a busy respiratory bay, secretion clearance is rarely one manoeuvre in isolation. This guide focuses on how nurses deliver ordered chest physiotherapy (CPT)—postural drainage, percussion, vibration, and coached cough—while watching for hypoxia symptoms, shortness of breath, and positioning risks, then hand off changes promptly to physiotherapy or medical teams.

Quick facts
Key takeaway
Chest physiotherapy only earns its place when retained secretions and tolerable positioning align. If cough is ineffective, chest congestion is worsening, or cardiovascular or neuro risk forbids drainage angles, stop the manoeuvre, optimise support (oxygen, analgesia, bronchodilators if ordered), and escalate—do not “push through” percussion or steep drainage when the patient is deteriorating.

What is chest physiotherapy?
Chest physiotherapy is a set of manual and positioning techniques used to move airway secretions toward the central airways so the patient can clear them by coughing, huffing, or assisted devices. In contemporary practice it commonly includes postural drainage, percussion, vibration, and coaching of breathing and cough—sometimes alongside albuterol or ipratropium when prescribed for bronchospasm or reactive airways, and always alongside a baseline respiratory assessment.
It supports nursing care when patients with bronchiectasis, COPD exacerbation with tenacious sputum, cystic fibrosis (when cared for under specialist respiratory plans), or selected postoperative states struggle with secretion clearance despite hydration, analgesia, and mobilisation. It does not replace antibiotics in pneumonia, nor definitive management of atelectasis when the primary issue is obstruction or pleural disease on chest X-ray.
When airway clearance fits—and when it does not
Respiratory therapy literature distinguishes routine versus targeted airway clearance. For many hospitalised adults without cystic fibrosis, guidelines have moved away from indiscriminate CPT for uncomplicated pneumonia or stable COPD when the patient can mobilise secretions with an effective cough. That matters at the bedside: your shift question is not “Should everyone get CPT?” but “Does this patient have retained secretions plus sufficient cardiopulmonary reserve for the planned positions and forces?”
Pair subjective findings (wheezing, coarse crackles that shift after cough, reduced air entry) with objective cues (rising work of breathing, falling saturation during exertion, large-volume or thick sputum) and the medical plan. If the plan is unclear, confirm with physiotherapy or the responsible clinician before steep drainage angles or vigorous percussion.
Common indications (ordered and individualised)
| Clinical picture | Why CPT may be rational |
|---|---|
| Tenacious secretions with weak cough | Manual techniques can augment peak expiratory flow episodes and centralise secretions for expectoration or airway suctioning when artificial airways exist. |
| Bronchiectasis / cystic fibrosis care plans | Long-term airway clearance is a cornerstone; hospital nurses reinforce prescribed positions and devices between physiotherapy visits. |
| Selected postoperative patients | When secretion retention complicates recovery and other measures (analgesia, early mobility, incentive strategies where used) are insufficient—always follow surgical team limits. |
| Neuromuscular compromise | Insufflation–exsufflation or cough-assist programmes may dominate; manual CPT is adjunctive and must follow specialist parameters. |
Contraindications, precautions, and pause rules
Treat the list below as a screening framework; institutional protocols may vary. When in doubt, choose a safer modified technique (smaller angle, shorter duration, lighter percussion) or pause until the responsible clinician or physiotherapist reviews.
- Suspected or known untreated pneumothorax, haemodynamic shock, or acute coronary syndrome without clearance.
- Active haemoptysis or uncontrolled coagulopathy where percussion risks bleeding (seek explicit direction).
- Rib fractures, flail chest, or spinal instability where manual forces are unsafe.
- Raised intracranial pressure or neurosurgical concerns where head-down positioning is prohibited.
- Severe osteoporosis, recent sternotomy, spinal surgery, or large ventral hernia—avoid focal impact and high-amplitude vibration.
- Pulmonary oedema, uncontrolled dyspnoea, or marginal oxygenation requiring high FiO₂.
- Tracheal or oesophageal anastomoses, recent lung resection, or indwelling devices near the percussion field.
- Pregnancy (second/third trimester) and significant ascites—avoid prolonged steep head-down positions.
- Apply airborne precautions when open cough generates aerosols in suspected or confirmed transmissible respiratory pathogens per local policy.
- Use fluid-resistant PPE, perform hand hygiene before and after, and dispose of contaminated tissues and sputum pots safely.
- After productive clearance, consider oral care where policy supports it to reduce aspiration risk in vulnerable patients.
Drainage angles, lines, skin, and the “head-down” decision
Postural drainage aims to use gravity so secretions move from peripheral airways toward central bronchi. Many UK and European services now limit or avoid steep Trendelenburg because of cardiovascular and cerebral venous effects; NHS patient leaflets often emphasise side-lying segmental positions instead. Align with your trust’s physiotherapy chart rather than improvising extreme angles.
When explicitly ordered and tolerated
- Re-check BP, heart rate, and SpO₂ before and during; stop for dizziness, palpitations, or sustained desaturation.
- Secure IV lines, chest drains, feeding tubes, and urinary catheters; pad pressure points.
- Never leave cognitively impaired or heavily sedated patients unattended in unstable positions.
Common ward-default when steep tilt is unsuitable
- Targets lateral segments with pillows supporting neutral neck alignment.
- Often better tolerated in heart failure, obesity, third-trimester pregnancy, or post–abdominal surgery.
- Combine with coached deep breathing and cough; reassess auscultation after each segment.
Classic teaching links apical segments with semi-upright or leaning-forward positions, lateral segments with side-lying with the affected side up or down per chart, and basal segments with prone–side hybrid or modest head-down tilt only if permitted. Because diagrams differ, carry your service’s approved map—do not guess from memory alone.
Equipment checklist
Pre-procedure assessment
Complete a focused respiratory assessment and review trends on pulmonary function tests or sputum culture results only as context for infection management—your immediate checks are bedside stability and comfort.
Chest physiotherapy procedure steps
Verify the order and scope of practice
Confirm written instructions for positions, duration, frequency, and any restrictions (for example “no percussion over sternotomy”). If the order conflicts with your assessment, clarify before proceeding.
Explain and agree a stop signal
Tell the patient what sensations to expect, that chest tightness or secretion movement may transiently feel uncomfortable before clearance, and that they should signal dizziness, sharp pain, or intolerable breathlessness immediately.
Optimise the environment
Privacy screen, bed at a safe working height, call bell within reach, suction available if indicated, and clutter-free floor space if the patient will sit leaning over a table edge for upper-lobe drainage per plan.
Position for the first target segment
Use the approved drainage map. Support the neck, hips, and knees; offload the brachial plexus when arms are elevated. Re-check SpO₂ after a brief settling period in the new posture (per local protocol) before adding percussion.
Apply controlled percussion
With a cupped hand or single-use device, create a hollow rhythm over the intercostal spaces of the target lobe, staying over muscle and rib cage with a thin towel barrier. Avoid spinal processes, scapular tips, breasts, kidneys, and the xiphisternum. Institutional protocols may vary for cadence and duration per segment—do not invent rigid second counts if your policy differs.
Add vibration on exhalation (if ordered)
Firmly press both hands (or one hand over the other) on the chest wall as the patient exhales slowly after a deep breath. Coordinate with the patient’s breathing pattern; stop if rib pain or desaturation appears.
Coach clearance cycles
Alternate 2–3 slow deep breaths with 1–2 strong coughs or huffs. Offer tissues; encourage expectoration into a pot for sputum sample collection if a specimen is due. For artificial airways, coordinate with suctioning per protocol.
Reposition to comfort and reassess
Return the patient to their preferred resting position, re-measure vital signs and SpO₂, and auscultate for change in air entry or shift of secretions.
Document and communicate
Record segments treated, tolerance, volume and character of sputum, any adverse events, and who was notified. Hand over unresolved findings to the next shift or physiotherapy.
Sequence at a glance
Monitoring, complications, and escalation
| Finding during or after CPT | Possible concern | Nursing action |
|---|---|---|
| Sustained desaturation or new cyanosis | Hypoventilation, mucus plugging, pulmonary oedema, pneumothorax | Stop technique, optimise oxygen per protocol, call for urgent review, prepare for escalation imaging or ABG if ordered. |
| Sharp pleuritic pain or rib click | Rib injury, musculoskeletal strain, surgical complication | Stop percussion, immobilise/support chest, notify clinician, obtain imaging if directed. |
| Large-volume haemoptysis | Airway bleeding source | Position bleeding lung dependent if policy directs, maintain airway, call emergency team, withhold further CPT until cleared. |
| Sudden anxiety, headache, bradycardia in steep head-down | Raised ICP effect, vagal response, haemodynamic intolerance | Return to neutral tilt, monitor neurological status, notify team. |
Call your emergency or rapid-response pathway for respiratory arrest, massive haemoptysis, suspected pneumothorax, or any rapid deterioration you cannot reverse with basic airway and oxygen measures.

NCLEX-Style Case Review
NCLEX-style clinical judgment practice — Postural drainage and cough coaching carry real respiratory risk; items here cover chest physiotherapy, including a priority action, select-all-that-apply cue recognition, and trend interpretation after intervention (recognise cues → analyse → prioritise → act → evaluate outcomes).
Unfolding case — respiratory ward. Mr. Chen, 68, has COPD with thick secretions and a productive cough. SpO₂ is 91% on 2 L/min nasal cannula. Lung sounds are diminished at the right base. The physiotherapy chart orders side-lying drainage to the right lower lobe with coached coughing; percussion over the sternotomy is restricted.
Answer key & rationale
Frequently asked questions
Is chest physiotherapy the same as pulmonary rehabilitation?
Not exactly. Pulmonary rehabilitation is a broader supervised programme of exercise and education. Chest physiotherapy describes manual and positioning techniques used to mobilise secretions, often as an ordered component of respiratory care.
Should chest physiotherapy be used for every pneumonia patient?
Major respiratory therapy guidance cautions against routine nonpharmacologic airway clearance for uncomplicated pneumonia in adults without secretion retention. Use when there is a clear secretion burden or per specialist/physiotherapy plan.
What is the main risk of head-down postural drainage?
Trendelenburg or steep head-down positioning can worsen dyspnoea, increase intracranial venous pressure, and stress the cardiovascular system. Many services avoid or modify these positions; follow local policy.
Where should percussion be avoided?
Avoid percussion over the spine, breasts, bare skin without padding, kidneys, liver margin if tender, surgical wounds, fractures, and indwelling devices unless explicitly cleared by the responsible clinician.
How do I know the session helped?
Look for improved air entry, change in sputum volume or ease of expectoration, reduced work of breathing, and patient-reported comfort. Lack of change after repeated sessions should prompt reassessment and escalation per protocol.
Who should perform chest physiotherapy?
Scope varies by employer and country. Many acute hospitals use respiratory physiotherapists for complex plans while nurses deliver ordered components; always work within your credentialing and local delegation policy.
