Annexure B: PAL Home Pulmonary Rehabilitation (PR) Guide for COPD
Pulmonary Rehabilitation is one of the most effective treatments for COPD. It improves breathlessness, exercise capacity, and quality of life. This home-based PR guide can be used when formal PR programs are not accessible.
What is Pulmonary Rehabilitation?
PR is a structured program combining:
- Exercise training
- Breathing techniques
- Education about COPD
- Nutritional advice
- Psychological support
Who Should Do Home PR?
- All COPD patients, especially GOLD B and E
- Post-exacerbation recovery (start 2-4 weeks after)
- Those with reduced exercise tolerance or breathlessness
- Patients unable to access hospital-based PR programs
Stop exercise and seek medical advice if you experience:
• Chest pain or severe breathlessness
• Dizziness or feeling faint
• Heart racing (pulse >120 bpm at rest)
• SpO₂ drops below 88%
• Unwell with fever or acute exacerbation
A. Breathing Techniques
1. Pursed-Lip Breathing (PLB)
- Breathe in through nose (2 counts)
- Purse lips as if blowing a candle
- Breathe out slowly through pursed lips (4 counts)
- Use during breathlessness or exercise
2. Diaphragmatic Breathing
- Sit or lie comfortably
- Place one hand on chest, one on belly
- Breathe in through nose - belly should rise, chest stays still
- Breathe out slowly through pursed lips
- Practice 5-10 minutes, 2-3 times daily
3. Paced Breathing During Activity
- Coordinate breathing with movement
- Example: Walking - breathe in for 2 steps, out for 3-4 steps
- Use PLB if breathless
B. Home Exercise Program
Warm-Up (5 minutes)
- Gentle arm circles, shoulder rolls
- March in place slowly

- Organize frequently used items within easy reach
- Use assistive devices if needed (shower chair, long-handled tools)
Activity Pacing:
- Break tasks into smaller steps
- Alternate heavy and light activities
- Don't rush - slow and steady
- Ask for help when needed
E. Psychological Wellbeing
COPD can affect mood and mental health:
- Stay socially connected with family and friends
- Join COPD support groups if available
- Practice relaxation techniques (meditation, gentle music)
- Set realistic goals and celebrate small achievements
- Speak to healthcare provider if feeling depressed or anxious
F. When to Seek Help
Contact your healthcare provider if:
- Increased breathlessness not relieved by usual medicines
- Change in sputum color, amount, or thickness
- Fever or chest pain
- Swelling in ankles or legs
- Increased fatigue or confusion
- Unable to perform usual home exercises
Annexure C: COPD Vaccination Schedule
Vaccination is a cornerstone of COPD preventive care. All COPD patients should receive appropriate vaccinations to reduce exacerbations, hospitalizations, and mortality.
1. Pneumococcal Vaccination
COPD patients are at increased risk of pneumococcal pneumonia and exacerbations. Pneumococcal vaccination is strongly recommended in adults with COPD.
Recommended approach:
- Adults ≥50 years or younger adults with chronic lung disease should receive a conjugate pneumococcal vaccine (PCV15 or PCV20).
- Give 1 dose of PCV20 or PPSV23 at least 8 weeks after last PCV dose.
- For those who have received PPSV23 previously, a conjugate vaccine (PCV20/21) may still be given if available.
- Revaccination with PPSV23 after 5 years may be considered in very high-risk patients.
2. Influenza Vaccination
Annual influenza vaccination is essential for COPD patients to prevent exacerbations and hospitalizations.
Sri Lanka experiences two influenza peaks: April-June and November-February. Vaccinate before the main peak (March-April).
- Annual vaccination is recommended for all COPD patients, especially those ≥65 years or with frequent exacerbations.
- Twice-yearly vaccination may be considered in very high-risk patients (e.g., severe COPD, immunocompromised) if feasible.
- Either Northern or Southern Hemisphere vaccine formulation may be used based on availability.
3. COVID-19 Vaccination
COPD patients are at higher risk for severe COVID-19 outcomes. All patients should be up to date with the national schedule, including boosters.
- Record date and type of last COVID-19 vaccine and ensure booster doses as per Ministry of Health guidance.
- Strongly advise vaccination for those on inhaled corticosteroids or with multiple comorbidities.
4. Varicella (Chickenpox) Vaccination
Varicella vaccine is not part of the routine national schedule in Sri Lanka but is available privately.
- Consider vaccination for adults with COPD who have no prior history of chickenpox or are seronegative.
- Schedule: Two doses 4-8 weeks apart for those aged ≥13 years.
- Recommended mainly for high-risk adults (e.g., healthcare workers, caregivers).
5. Vaccination Summary Table
| Vaccine | Indication in COPD | Schedule | Remarks |
|---|---|---|---|
| Pneumococcal (PCV15/20 ± PPSV23) | All adults ≥50y or high-risk COPD | PCV dose, then PPSV23 at 8+ weeks | Booster PPSV23 at 5 years if high risk |
| Influenza (inactivated) | All COPD patients | Annually (Mar-Apr) | Optional 2nd dose (Sep-Oct) for very high risk |
| COVID-19 | All COPD patients | As per national MOH schedule | Ensure up-to-date booster |
| Varicella | Seronegative or no history adults | 2 doses, 4-8 weeks apart | Private sector; not in public NIP |
6. Implementation in COPD Care / e-Health Record
- Add a 'Vaccination Status' section to COPD e-Health Record (PCV, Influenza, COVID-19, Varicella).
- Set reminders for annual influenza vaccination and COVID-19 booster.
- Check vaccination status at each annual review.
- Provide patient counselling on vaccine benefits, timing, and local access options.

Annexure D: Smoking Cessation and Biomass Exposure Counselling
Stopping smoking and reducing biomass exposure are the single most important interventions to slow COPD progression and improve outcomes.
1. Why Quitting Matters in COPD
Immediate Benefits (within days-weeks):
- Breathing becomes easier
- Cough and sputum improve
- Energy levels increase
- Sense of smell and taste return
Long-term Benefits:
- Slows lung function decline
- Reduces exacerbations by 30-40%
- Decreases risk of lung cancer
- Improves response to medications
- Increases survival
2. The 5 A's Approach to Smoking Cessation
ASK - Identify tobacco users at every visit
"Do you currently use tobacco - cigarettes, beedis, cigars, chewing?"
Document: Type, amount (cigarettes/beedis per day), years of use
ADVISE - Strongly urge all tobacco users to quit
"Quitting smoking is the most important thing you can do for your lungs and your health. I strongly recommend you quit now."
- Be clear, strong, and personalized
- Link advice to COPD symptoms and test results
- Avoid being judgmental
ASSESS - Determine willingness to quit
"Are you willing to try to quit smoking now?"
Stages of Change:
| Stage | Characteristics | Approach |
|---|---|---|
| Pre-contemplation | Not thinking about quitting | Provide information, plant seeds |
| Contemplation | Thinking about it | Explore ambivalence, discuss benefits |
| Preparation | Ready to quit soon | Set quit date, develop plan |
| Action | Currently quitting | Provide support, medication if needed |
| Maintenance | Quit for >6 months | Prevent relapse, reinforce success |
| Relapse | Returned to smoking | Non-judgmental, learn from attempt |
ASSIST - Help patient with quit plan
Set a Quit Date:
- Within next 2-4 weeks
- Meaningful date (birthday, holiday, family event)
- Write it down, tell family and friends
Prepare for Quit Day:
- Remove all tobacco products from home, car, workplace
- Avoid triggers (alcohol, tea shops, smoking friends)
- Plan activities for urge management
- Stock healthy snacks (carrots, nuts, chewing gum)
- Plan first smoke-free day in detail
Get Support:
- Tell family, friends, coworkers
- Join support group if available
- Use telephone quitline if available
- Consider counselling
Consider Medication:
- Nicotine replacement therapy
- Prescription medications
- Discuss options with doctor
ARRANGE - Schedule follow-up contact
- Within 1 week of quit date
- Then at 1 month, 3 months, 6 months
- More frequent if needed
- Celebrate successes, address challenges
3. Pharmacotherapy for Smoking Cessation
A. Nicotine Replacement Therapy (NRT)
How it works:
- Provides nicotine without harmful tobacco chemicals
- Reduces withdrawal symptoms and cravings
- Doubles quit success rates
Forms available in Sri Lanka:
| Type | Dose/Use | Pros | Cons |
|---|---|---|---|
| Patch | 21 mg, 14 mg, 7 mg daily | Easy, steady level, once daily | Skin irritation, no hand-to-mouth |
| Gum | 2 mg or 4 mg as needed | Controls acute cravings | Jaw fatigue, technique needed |
| Lozenge | 2 mg or 4 mg as needed | Discreet, easy | Throat irritation, technique needed |
How to choose:
- Heavy smokers (>20/day): Start with 21 mg patch + gum/lozenge for breakthrough cravings
- Moderate smokers (10-20/day): 14 mg patch or gum/lozenge alone
- Light smokers (<10/day): 7 mg patch or gum/lozenge alone
Duration: Usually 8-12 weeks, then taper. Some may need longer.
Contraindications: Recent heart attack (within 2 weeks), unstable angina, severe arrhythmias
B. Prescription Medications
Varenicline:
- How it works: Blocks nicotine receptors, reduces cravings
- Dose: Start 0.5 mg daily for 3 days, then 0.5 mg twice daily for 4 days, then 1 mg twice daily for 11-24 weeks
- Start: 1 week before quit date
- Effectiveness: Triples quit rates
- Side effects: Nausea (common, improves with time), vivid dreams, mood changes
- Monitoring: Assess mood at each visit, especially if history of depression
- Safety in COPD: Safe and effective; preferred choice for motivated patients
Bupropion:
- How it works: Antidepressant that reduces cravings and withdrawal
- Dose: 150 mg daily for 3 days, then 150 mg twice daily for 7-12 weeks
- Start: 1-2 weeks before quit date
- Effectiveness: Doubles quit rates
- Side effects: Insomnia, dry mouth, anxiety
- Contraindications: Seizure disorder, eating disorders, heavy alcohol use
- Safety in COPD: Safe; good option if depression also present
Combination Therapy:
- Varenicline + NRT patch may be more effective than either alone
- Consider for highly dependent smokers who have failed single therapy
- Requires specialist supervision
4. Biomass Exposure Reduction
Common Sources in Sri Lanka:
- Firewood cooking (kitchen smoke)
- Paddy drying (seasonal, intense exposure)
- Coconut husk burning
- Indoor open fires
- Incense and mosquito coils (minor contributors)
- Kerosene lamps
Health Impact:
- Similar lung damage to tobacco smoking
- Particularly affects women doing household cooking
- Children exposed also at risk
- Combined smoking + biomass exposure = worse outcomes
Harm Reduction Strategies:
A. Improve Kitchen Ventilation:
- Open windows and doors while cooking
- Install chimney or exhaust fan if possible
- Cook outside or in separate kitchen building when feasible
- Use improved cookstoves with chimneys (Anagi Lipa programs)
B. Fuel Switching (in order of preference):
- Best: Electricity or LPG (liquid petroleum gas)
- Cleanest options
- Government subsidies available for low-income families
- Long-term cost savings despite higher initial cost
- Better: Biogas from home digesters
- Renewable, clean
- Initial investment required
- Suitable if have livestock
- Good: Improved biomass stoves
- 50-70% reduction in smoke exposure
- Much less expensive than fuel switching
- Programs available through government and NGOs
- Minimal improvement: Dry, seasoned wood instead of wet wood
- Reduces smoke but still significant exposure
C. Behavior Modification:
- Light fire outdoors, bring inside once established (less smoke)
- Avoid bending over fire while cooking
- Take breaks during cooking to breathe fresh air
- Assign cooking tasks to family members without COPD
- Batch cook to reduce total cooking time
- Use pressure cookers and covered pots (shorter cooking time)
D. Personal Protection:
- Well-fitted N95 mask while cooking (not cloth masks)
- Change position to stay out of smoke plume
- Tie back hair and wear long sleeves (reduces smoke absorption)
Annexure E: Early and Pre-COPD Spectrum (Pre-COPD and PRISm)
1. Concept Overview
| Term | Definition | Why It Matters |
|---|---|---|
| Pre-COPD | Respiratory symptoms ± imaging or physiological abnormalities suggestive of early airway disease but post-BD FEV₁/FVC ≥0.7 | Indicates incipient COPD - target for prevention through lifestyle, exposure, and vaccination |
| PRISm (Preserved Ratio Impaired Spirometry) | FEV₁ <80% predicted with FEV₁/FVC ≥0.7 | Transitional state - some progress to COPD, some revert to normal. Common in obesity, post-TB, biomass exposure |
2. Spectrum of Progression
Risk Factors → Pre-COPD → PRISm → Established COPD
| Stage | Pathology/Function | Imaging/Tests | Clinical Clues |
|---|---|---|---|
| Pre-COPD | Small-airway inflammation, early air-trapping | ↓ FEF₂₅₋₇₅%, ↑ RV/TLC, IOS: ↑R5-R20 | Cough, exertional breathlessness, normal FEV₁/FVC |
| PRISm | Hyperinflation, dysanapsis, early emphysema | FEV₁ <80%, normal ratio, HRCT air-trapping | Often obese/metabolic, post-TB changes |
| COPD | Fixed airflow obstruction | FEV₁/FVC <0.7 post-BD | Chronic dyspnoea, productive cough |
3. Management Framework
| Goal | Pre-COPD | PRISm |
|---|---|---|
| Exposure Control | Stop smoking, remove biomass, improve ventilation | Same as Pre-COPD |
| Vaccination | Influenza, Pneumococcal, Pertussis, COVID | Same |
| Physical Activity/PR | Daily walking, breathing exercises | Early pulmonary rehab if symptomatic |
| Nutrition | Maintain BMI 20-25; treat sarcopenia | Weight reduction if obese; control metabolic syndrome |
| Pharmacologic | No routine bronchodilators unless reversible | LABA/LAMA trial if symptomatic with low FEV₁ |
| Monitoring | Spirometry every 12-18 months | Every 6-12 months |
| Referral | Worsening symptoms or FEV₁ decline >100 mL/yr | Same + HRCT if decline persists |
4. Sri Lanka-Specific Notes
- Biomass-PRISm common in rural women; often mislabelled as asthma
- Post-TB airflow patterns mimic PRISm due to airway distortion without obstruction
- Childhood undernutrition + infection leads to early small-airway disease
- Integrate detection into NCD and Chest Clinics using handheld spirometry and a short exposure questionnaire
5. Follow-Up Algorithm
Annexure F: INHALER DEVICE SELECTION AND COMPARISON GUIDE
Overview of Inhaler Device Classes
Selecting the appropriate inhaler device is as critical as choosing the correct medication. Device selection must be individualized based on patient's age, inspiratory flow capacity, coordination ability, cognitive function, and environmental considerations.
Comprehensive Device Comparison
| Attribute | pMDI | Single-Dose DPI | Multi-Dose DPI | BA-MDI | SMI |
|---|---|---|---|---|---|
| Propellant/Activation | HFA propellant (manual press) | No propellant; capsule punctured per use | No propellant; built-in reservoir or blister strip | HFA-based; inhalation triggers actuation | No propellant; spring-driven liquid mist |
| Inspiratory Flow | Low; suitable for all | High (≥40-60 L/min) | Moderate (~30-50 L/min) | Low-moderate | Low (slow, gentle) |
| Coordination | Required (major error source) | Not required | Not required | Not required | Not required |
| Spacer | Strongly recommended; improves deposition, reduces side effects | Not compatible | Not compatible | Usually not required | Not required |
| Ease of Use | Moderate; requires training | Moderate; capsule loading | High; dose counter | High; minimal coordination | Very high; easy slow inhalation |
| Dose Counter | Common on newer models | Not typical | Standard | Available on some | Integrated on most |
Device Selection Algorithm
Step 1: Assess Patient Capability
Inspiratory Flow Capacity:
- Measure peak inspiratory flow (PIF) if available
- Single-dose DPI requires ≥40-60 L/min
- Multi-dose DPI requires ~30-50 L/min
- pMDI, BA-MDI, SMI suitable for all flow rates
Coordination Ability:
- Poor hand-breath coordination → DPI, BA-MDI, or SMI preferred
- Children <5 years → pMDI + spacer with face mask
- Children 5-12 years → pMDI + spacer OR multi-dose DPI
- Adults/adolescents → Any device based on preference and flow
Step 2: Match Device to Clinical Context
Acute Exacerbations/Emergency:
- pMDI + spacer (nebulizer if severe)
- Reliable delivery regardless of inspiratory effort
- SMI acceptable if patient familiar with device
Maintenance Therapy:
- Multi-dose DPI preferred for stable patients (dose counter, no propellant)
- BA-MDI for transitional patients learning technique
- SMI for patients requiring low-carbon footprint and reliable delivery
Step 3: Consider Environmental and Cost Factors
Environmental Impact: Next-generation HFA-152a propellants offer ~90-95% reduction in global warming potential compared to standard HFA-134a.
Cost and Availability:
- Multi-dose DPI may have higher upfront cost but better adherence
- pMDI + spacer remains most cost-effective in resource-limited settings
Spacer Technique & Maintenance
Benefits of Spacers with pMDI
✅ Reduce oropharyngeal deposition by 80-90%
✅ Minimize systemic absorption (especially ICS)
✅ Reduce local side effects (dysphonia, oral thrush)
✅ Eliminate need for hand-breath coordination
Spacer Types
Valved Holding Chamber (VHC):
- One-way valve allows inhalation timing flexibility
- Preferred for children and elderly
- Most common type available
Non-Valved Spacer:
- Simple tube design
- Requires immediate inhalation after actuation
- Cost-effective but less forgiving
Correct Spacer Technique
- Assemble spacer and attach pMDI
- Shake pMDI 5 times
- Breathe out gently (away from spacer)
- Place mouthpiece between lips (tight seal)
- Actuate pMDI ONCE into spacer
- Breathe in slowly and deeply (5-10 seconds for VHC)
- Hold breath for 10 seconds
- Wait 30-60 seconds before second puff if needed
- Rinse mouth after ICS use
Spacer Maintenance
- Wash weekly with warm soapy water
- Air dry (do not wipe - creates static charge)
- Replace every 6-12 months or if damaged/cracked
- Avoid detergents with surfactants (increases static)
❌ Multiple actuations into spacer (drug settles on walls)
❌ Delaying inhalation >2 seconds after actuation
❌ Breathing into spacer (humidifies and reduces delivery)
❌ Not cleaning spacer (drug buildup reduces delivery)
Device-Specific Technique Checklists
pMDI (with Spacer) Technique ✅
- Remove cap and shake inhaler 5 times
- Attach pMDI to spacer
- Breathe out gently (away from spacer)
- Place spacer mouthpiece between lips (tight seal)
- Press canister ONCE
- Breathe in slowly and deeply
- Hold breath for 10 seconds
- Wait 30-60 seconds before next puff
- Rinse mouth after ICS
Multi-Dose DPI (Reservoir Type) Technique ✅
- Remove cap and hold upright
- Twist base fully in one direction, then back until click heard
- Breathe out fully (away from device)
- Place mouthpiece between lips (tight seal)
- Breathe in deeply and forcefully
- Remove device and hold breath for 10 seconds
- Breathe out slowly (away from device)
- Replace cap
- Rinse mouth after ICS
Soft-Mist Inhaler (SMI) Technique ✅
- Open cap until fully vertical
- Point device toward ground, press dose-release button
- Breathe out gently (away from device)
- Close lips around mouthpiece
- Press dose-release button while breathing in slowly and deeply
- Continue breathing in slowly (mist lasts ~1.5 seconds)
- Hold breath for 10 seconds
- Close cap
