Chest Physiotherapy | GCCNurseJobs Clinical Guide

🫁 What is Chest Physiotherapy (CPT)?

Chest physiotherapy (CPT) is a group of physical techniques designed to improve respiratory function by mobilising and clearing pulmonary secretions, preventing atelectasis, and improving ventilation-perfusion (V/Q) matching. It is an essential component of respiratory nursing care across ICU, medical, surgical, and community settings.

Three Core Goals: (1) Mobilise secretions to central airways, (2) Prevent/treat atelectasis, (3) Improve V/Q matching and oxygenation.

📋 CPT Techniques Overview

Technique	Description	Best For
Postural Drainage	Position patient to use gravity to drain specific lung segments	Bronchiectasis, COPD, CF
Percussion (Clapping)	Rhythmic clapping over chest wall with cupped hands	Loosening adherent secretions
Vibration	Fine oscillatory pressure during expiration	Combined with postural drainage
ACBT	Active cycle of breathing technique — 3-phase cycle	All secretion-producing conditions
Autogenic Drainage	Controlled breathing at different lung volumes to shear secretions	CF, bronchiectasis
Incentive Spirometry	Visual feedback device encouraging slow deep breaths	Post-operative atelectasis prevention
PEP Devices	Positive expiratory pressure masks/devices	CF, bronchiectasis, COPD exacerbation

✅ Indications for CPT

Primary Indications

COPD acute exacerbation
Bronchiectasis
Cystic fibrosis (daily CPT)
Post-operative atelectasis
Ventilator-associated pneumonia prevention

Additional Indications

Pneumonia with retained secretions
Lung abscess drainage
Prolonged mechanical ventilation
Neuromuscular disease (weak cough)
Post thoracic surgery

🔍 Pre-CPT Assessment

Respiratory Assessment

Respiratory rate, SpO₂, work of breathing
Auscultation — wheeze, crackles, reduced breath sounds
Sputum characteristics — colour, volume, viscosity
Cough effectiveness — productive or non-productive
Dyspnoea score (Borg scale or MRC dyspnoea scale)

Haemodynamic Assessment

Blood pressure — avoid if systolic <90 mmHg or >180 mmHg
Heart rate — avoid if HR <50 or >130 bpm
SpO₂ — baseline before CPT; monitor continuously
Recent ECG — check for arrhythmias, recent MI

Pre-treatment Protocol: Administer bronchodilator nebuliser (e.g., salbutamol) 15-20 minutes before CPT to open airways, reduce bronchospasm, and maximise effectiveness of secretion mobilisation.

🚫 Contraindications to CPT

Absolute Contraindications:

Undrained pneumothorax — CPT can worsen air leak
Massive haemoptysis — active bleeding; CPT can increase bleeding
Unstable spinal injury — positioning would risk cord damage
Acute haemodynamic instability / cardiogenic shock
Raised intracranial pressure (ICP) — head-down position CONTRAINDICATED (raises ICP further)

Relative Contraindications

Recent thoracic surgery (within 48h) — risk of wound dehiscence
Severe osteoporosis — percussion can cause rib fractures
Active pulmonary embolism
Uncontrolled pain limiting cooperation
Immediately post-meals — risk of vomiting and aspiration

ICP Alert: Postural drainage (head-down position for lower lobe drainage) is absolutely contraindicated in raised ICP. This is a common exam trap — always check ICP status before positioning.

🔄 ACBT — Active Cycle of Breathing Technique

ACBT is the most widely used airway clearance technique for adults. It consists of three phases repeated in a cycle until secretions are cleared:

1 Breathing Control (BC): Relaxed tidal breathing at normal rate and depth. Allows airways to recover and prevents bronchospasm. Continue for 2-3 breaths.

2 Thoracic Expansion Exercises (TEE): 3-5 deep slow inspirations to full lung capacity, held 3 seconds, then passive exhalation. Mobilises peripheral secretions. Often combined with percussion or vibration.

3 Forced Expiration Technique (FET / Huff): 1-2 huffs (forced expiration through open mouth/glottis) followed by breathing control. Moves secretions from peripheral to central airways. Cough when secretions reach upper airway.

Cycle Sequence: Breathing Control → Thoracic Expansion Exercises → Breathing Control → Forced Expiration (Huff) → Cough → Breathing Control → Repeat

🫧 Postural Drainage

Positions are used to drain specific lung segments using gravity. The patient is positioned so the affected segment is uppermost and the bronchus draining it points downward.

Lung Segment	Position	Notes
Lower lobes (posterior segment)	Head-down prone or side-lying	CONTRAINDICATED if raised ICP
Lower lobes (anterior segment)	Head-down supine	Monitor for reflux/aspiration
Upper lobes	Sitting upright or leaning forward	Safest for most patients
Right middle lobe / lingula	Head-down quarter turn to each side	Common area for nosocomial pneumonia

Reflux Risk: Head-down positioning increases gastro-oesophageal reflux risk. Always ensure patient has not eaten for at least 1-2 hours before head-down postural drainage. Monitor for nausea and aspiration signs.

🌬️ Incentive Spirometry

Incentive spirometry uses a flow- or volume-based device to encourage sustained maximal inspiration (SMI), which opens collapsed alveoli and prevents post-operative atelectasis.

Technique

Sit patient upright at 45-90 degrees
Inhale slowly through the mouthpiece to raise the flow ball to the target zone
Hold inspiration for 3-5 seconds to maintain alveolar recruitment
Exhale slowly through mouth
Rest 2-3 breaths between attempts

Post-operative Protocol: 10 deep breaths per hour while awake, starting from the day of surgery (or as soon as patient is alert post-anaesthesia). The incentive spirometer ball should be kept elevated throughout the sustained inspiration.

⏱️ CPT Frequency and Timing

Acute exacerbations (COPD, bronchiectasis, CF): 2-4 times daily
Stable maintenance (bronchiectasis, CF): 1-2 times daily
Post-operative: Hourly incentive spirometry; CPT as clinically indicated
Ventilated patients: Every 4-6 hours with suction; position changes every 2 hours
Timing: Avoid immediately after meals (reflux risk); ideally 30+ minutes before meals or 1-2 hours after
Duration: Typically 20-30 minutes per session for full ACBT + postural drainage

⚠️ Complications and Adverse Effects

Complication	Cause	Management
Hypoxaemia during CPT	Secretion mobilisation temporarily worsens V/Q	Supplemental O₂; pause and allow recovery; reassess SpO₂
Bronchospasm	Percussion irritates airways	Stop CPT; administer bronchodilator; reassess
Aspiration	Head-down position + full stomach	Fast patient 1-2h before; ensure nil reflux symptoms
Rib fracture	Percussion in osteoporosis/steroids	Use vibration instead of percussion; gentle technique
Haemoptysis	Suction trauma; friable mucosa	Stop CPT; assess volume; medical review
Increased ICP	Head-down positioning	Avoid head-down positions in raised ICP patients
Arrhythmias	Vagal stimulation; hypoxia	Monitor ECG; stop if arrhythmia develops

🛑 When to Stop CPT Immediately

SpO₂ falls below 88% (or below prescribed target)
New or worsening haemoptysis
Significant increase in dyspnoea or respiratory distress
Heart rate <50 or >130 bpm or new arrhythmia
Systolic BP <90 or >180 mmHg
Patient requests to stop — respect patient autonomy
Signs of pain suggesting rib injury

Documentation: Always document pre- and post-CPT SpO₂, RR, sputum characteristics (colour, volume, consistency), and patient tolerance. Report adverse events to the physiotherapist and medical team.

🌍 GCC-Specific Context

High COPD Burden in GCC — Smoking and Occupational Dust ▼

The GCC region has one of the highest rates of tobacco smoking among males globally, particularly in Saudi Arabia, Kuwait, and Qatar. Combined with significant occupational exposure to construction dust, desert particulates, and petrochemical fumes, COPD and chronic bronchitis are highly prevalent. This creates a large clinical demand for CPT skills. Nurses should be aware that many GCC patients may present with advanced COPD and require regular CPT as part of their management plan.

Ramadan — Adjusting CPT Timing and Patient Comfort ▼

During Ramadan, Muslim patients fast from dawn (Fajr) to sunset (Maghrib). CPT should continue as clinically indicated — it is a medical therapy and does not invalidate the fast. However, scheduling should be sensitive: (1) Nebulised bronchodilators before CPT may be better timed during non-fasting hours (after Iftar or before Suhoor) where possible; (2) Oral sputum expectoration and swallowing water are permissible for medical purposes; (3) CPT sessions may be more acceptable to patients in the evening after Iftar when energy levels are higher. Always involve the patient in scheduling decisions and consult hospital chaplaincy/religious guidance if needed.

Paediatric CPT for Cystic Fibrosis in GCC ▼

Cystic fibrosis (CF) is recognised in GCC populations with a significant consanguinity rate contributing to autosomal recessive conditions. CF centres in UAE (Dubai), Saudi Arabia (Riyadh, Jeddah), and Qatar provide specialised CPT programmes. Nurses working in paediatric respiratory units need competency in modified ACBT techniques for children and PEP device instruction for home use. Parents/caregivers require structured education in daily airway clearance technique.

VAP Prevention in GCC ICUs ▼

Ventilator-associated pneumonia (VAP) is a significant cause of morbidity in GCC ICUs. CPT — including regular position changes (every 2 hours), subglottic suctioning, oral hygiene, and head-of-bed elevation to 30-45 degrees — is a core component of VAP bundles mandated by DHA, DOH, and MOH. Nurses must document VAP bundle compliance as part of mandatory ICU quality indicators. Saudi Arabia's Saudi Critical Care Society (SCCFHS) guidelines include chest physiotherapy as standard care in mechanically ventilated patients.

❓ Practice MCQs

1. A nurse is about to commence chest physiotherapy (CPT) on a patient with COPD. To maximise the effectiveness of the treatment, the nurse should FIRST:

Correct answer: C — Bronchodilators administered 15-20 minutes before CPT open the airways, reduce bronchospasm, and maximise the effectiveness of secretion clearance techniques.

2. A nurse is teaching a post-abdominal surgery patient to use an incentive spirometer. Which instruction is MOST important?

Correct answer: B — Post-operative incentive spirometry protocol is 10 deep breaths per hour while awake. Slow sustained inspiration (held 3-5 seconds) recruits alveoli and prevents atelectasis. Sitting upright at 45-90 degrees is the correct position.

3. A patient with bronchiectasis requires postural drainage for lower lobe secretions. The nurse notes that the patient has a traumatic brain injury with ICP monitoring in situ. The nurse should:

Correct answer: C — Head-down positioning is absolutely contraindicated in raised ICP as it increases cerebral venous pressure and worsens ICP. Alternative positions and techniques (ACBT, PEP devices, vibration in neutral position) should be used instead.

4. During the forced expiration technique (FET/huff) in ACBT, the patient should be instructed to:

Correct answer: B — The huff (FET) involves forced expiration through an OPEN glottis and mouth (as if fogging a mirror). This is different from a cough which closes the glottis. The open glottis manoeuvre prevents bronchiolar collapse and is more effective at clearing peripheral secretions.
