Before

An Acute Exacerbation of a Chronic Condition (AECC) refers to a sudden worsening or flare-up of symptoms in a person who has an ongoing, long-term illness. This deterioration is typically more severe than the person’s usual day-to-day variations and may require medical intervention or hospitalization.

Pathophysiology and Clinical Manifestations of Acute Exacerbation of Chronic Conditions

Pathophysiology

The pathophysiology varies depending on the specific chronic condition but generally involves:

  • Triggering factors (e.g., infections, non-adherence to medications, environmental exposure, stress) that disrupt the person's usual balance or disease control.

  • Inflammatory responses or physiological decompensation due to the body’s inability to maintain homeostasis.

  • Progression of organ dysfunction or worsening of symptoms.

Examples:

  • Chronic Obstructive Pulmonary Disease (COPD): Exacerbation often triggered by respiratory infections; leads to increased airway inflammation, mucus production, and airflow obstruction.

  • Heart Failure: Fluid overload or ischemia leads to worsening symptoms such as pulmonary edema and reduced cardiac output.

  • Diabetes Mellitus: Poor glycaemic control or infection may lead to hyperglycaemia or diabetic ketoacidosis.

Clinical Manifestations

These vary by condition but often include:

  • Respiratory distress (e.g., shortness of breath in COPD or heart failure)

  • Fatigue and weakness

  • Increased pain or discomfort

  • Changes in vital signs (e.g., tachycardia, hypotension)

  • Altered mental status (e.g., confusion, lethargy)

  • Lab/imaging abnormalities (e.g., elevated inflammatory markers, abnormal ECG, X-rays)


Role of the Nurse in Coordinating and Supporting Person-Centred Care During an Acute Exacerbation

1. Clinical Assessment and Monitoring

  • Perform timely assessments (vital signs, symptom monitoring)

  • Recognize early signs of deterioration

  • Monitor response to treatment (e.g., oxygen therapy, diuretics)

2. Coordination of Care

  • Collaborate with interdisciplinary teams (doctors, physios, pharmacists)

  • Ensure appropriate referrals and continuity of care

  • Facilitate hospital admission or escalation of care when needed

3. Person-Centred Communication

  • Involve the person and their family in care decisions

  • Provide clear explanations about the condition and treatments

  • Respect cultural and individual preferences

4. Education and Self-Management Support

  • Educate on symptom recognition and when to seek help

  • Support adherence to medications and lifestyle modifications

  • Help create or revise an action plan (e.g., asthma or CHF action plan)

5. Emotional and Psychosocial Support

  • Address anxiety, fear, or distress related to the acute episode

  • Connect patients with counselling or support services if needed


Pathophysiology and Clinical Manifestations of an Acute Exacerbation of COPD

🔬 Pathophysiology of COPD

COPD is a progressive, irreversible lung disease that includes conditions like chronic bronchitis and emphysema. Its main characteristics are:

  • Chronic airway inflammation

  • Narrowing of the airways

  • Destruction of alveoli (air sacs), reducing gas exchange

  • Mucus hypersecretion

💥 What Happens During an Acute Exacerbation?

An acute exacerbation of COPD (AECOPD) is a sudden worsening of respiratory symptoms beyond usual day-to-day variation. The most common triggers are:

  • Respiratory tract infections (viral or bacterial)

  • Air pollution or allergens

  • Poor medication adherence

  • Cold weather or stress

Pathophysiological changes during AECOPD:

  1. Increased inflammation → leading to further airway narrowing

  2. Excess mucus production → blocks airflow

  3. Air trapping → due to impaired gas exchange

  4. V/Q mismatch (ventilation-perfusion) → causing hypoxaemia and possibly hypercapnia

All of this puts a strain on respiratory muscles, increases the work of breathing, and reduces oxygenation to tissues.

🩺 Clinical Manifestations of AECOPD

  • Increased dyspnoea (shortness of breath) – especially at rest or with minimal exertion

  • Increased cough and sputum production

  • Change in sputum colour – may indicate infection

  • Wheezing or chest tightness

  • Tachypnoea (rapid breathing) and tachycardia

  • Fatigue and confusion – due to hypoxia

  • Cyanosis in severe cases

Severe exacerbations may require hospitalization or ventilatory support.


The Nurse's Role in Person-Centred Care During an AECOPD

👩‍⚕ 1. Assessment and Monitoring

  • Frequent monitoring of respiratory rate, oxygen saturation, and work of breathing

  • Auscultation for wheezes, crackles, or diminished breath sounds

  • Monitor ABGs (Arterial Blood Gases) if available – to assess for respiratory acidosis or hypoxaemia

  • Observe for signs of fatigue or deterioration

🔄 2. Care Coordination

  • Liaise with doctors for treatment (e.g., bronchodilators, corticosteroids, antibiotics)

  • Coordinate respiratory therapy (e.g., nebulisers, chest physiotherapy)

  • Arrange for diagnostics (e.g., chest X-ray, sputum culture)

  • Plan for escalation of care (ICU referral if needed)

🗣 3. Person-Centred Communication

  • Involve the patient in all decisions (e.g., treatment goals, use of NIV)

  • Use non-technical language to explain interventions and progress

  • Be aware of anxiety, which often accompanies breathlessness – offer reassurance and information

🎓 4. Education and Self-Management

After stabilization, educate the person on:

  • Early signs of exacerbation and what to do (e.g., action plan)

  • Inhaler technique and adherence to meds

  • Avoiding triggers like smoke, dust, cold air

  • Pulmonary rehabilitation programs

  • Smoking cessation support if relevant

5. Psychosocial and Emotional Support

  • AECOPD can be frightening – provide emotional support

  • Involve family or carers in planning

  • Explore advanced care planning if appropriate (e.g., goals of care for recurrent/severe exacerbations)


Great question! Nursing actions during an Acute Exacerbation of COPD (AECOPD) are critical for stabilizing the patient, relieving symptoms, preventing complications, and supporting recovery. Below is a clear breakdown of key nursing actions—categorized into immediate care, monitoring, communication, coordination, and long-term support—all framed around person-centred care.


👩‍⚕ Nursing Actions During an Acute Exacerbation of COPD

🔴 1. Immediate Interventions (Stabilization)

Nursing Action

Rationale

Administer prescribed oxygen therapy (e.g., via nasal cannula or Venturi mask)

To maintain SpO₂ typically between 88–92% in COPD patients (to avoid suppressing respiratory drive)

Administer bronchodilators via nebuliser or inhaler (e.g., salbutamol, ipratropium)

To relieve bronchospasm and open airways

Administer systemic corticosteroids as prescribed (e.g., prednisolone)

To reduce airway inflammation

Administer antibiotics if infection is suspected

To treat underlying infection contributing to the exacerbation

Position patient in high Fowler’s position

To maximise lung expansion and ease breathing

Provide a calm, reassuring environment

To reduce anxiety, which can worsen dyspnoea


📊 2. Monitoring and Ongoing Assessment

Nursing Action

Rationale

Monitor vital signs and SpO₂ regularly

To detect signs of deterioration early (e.g., rising RR, falling SpO₂)

Perform chest auscultation

To assess breath sounds for wheeze, crackles, or diminished air entry

Monitor level of consciousness and fatigue

Confusion or lethargy may indicate hypoxaemia or hypercapnia

Monitor ABG results (if available)

To assess respiratory function and guide oxygen therapy

Track fluid intake/output if IV therapy or diuretics are given

Fluid balance is important in COPD management, especially if right-sided heart strain is present


🤝 3. Person-Centred Communication

Nursing Action

Rationale

Explain all procedures and treatments clearly and calmly

To build trust, reduce anxiety, and empower the person

Actively listen to the person's concerns

To provide emotional support and ensure care aligns with their values

Involve family or carers in care decisions (with consent)

Supports continuity of care and shared decision-making

Use non-verbal reassurance (e.g., eye contact, touch, calm tone)

Especially helpful when the person is breathless and can’t speak easily


🔄 4. Multidisciplinary Coordination

Nursing Action

Rationale

Notify medical team promptly of any deterioration

Ensures timely escalation or treatment modification

Coordinate with physiotherapists for chest physio or breathing techniques

To aid sputum clearance and improve lung function

Arrange respiratory nurse consult or referral to pulmonary rehab

For longer-term disease management support

Ensure timely administration of medications

To optimize response to treatment and symptom relief


🌱 5. Discharge Planning and Long-Term Support

Nursing Action

Rationale

Educate on inhaler technique and medication adherence

Incorrect use is a common cause of exacerbations

Provide a COPD action plan

Helps patients recognize and respond to early symptoms of exacerbation

Educate on trigger avoidance (smoking, pollutants, infection prevention)

Reduces risk of future exacerbations

Refer to smoking cessation programs (if relevant)

Smoking is the main cause of COPD progression

Discuss advanced care planning if exacerbations are frequent/severe

Encourages discussion about goals of care and preferences for future treatment


Definition of Acute Heart Failure

Acute Heart Failure (AHF) is a clinical syndrome characterized by:

  • A rapid onset or worsening of signs and symptoms of heart failure

  • It leads to reduced cardiac output, tissue hypoperfusion, increased pulmonary pressure, and congestion

  • Requires urgent medical evaluation and treatment

It can present de novo (new onset) or as a decompensation of chronic heart failure.


Risk Factors for Acute Heart Failure

Strong Risk Factors

  1. Older Age

    • Prevalence is ≥10% in people ≥70 years of age.

  2. Prior History of Heart Failure

    • Present in ~75% of patients hospitalized for AHF.

  3. Coronary Artery Disease (CAD)

    • Leading cause (~50% of AHF cases); myocardial ischemia impairs LV function.

  4. Hypertension

    • Present in 60–72% of cases; increases afterload and promotes LV hypertrophy.

  5. Valvular Heart Disease

    • Especially aortic stenosis and mitral regurgitation.

  6. Cardiac Arrhythmias (e.g., Atrial Fibrillation)

    • Present in 31–35% of patients.

  7. Myocarditis and Pericardial Disease

  8. Diabetes Mellitus

    • Contributes via ischemic and renal complications.

  9. Nonadherence to Medications

Weaker Risk Factors

  • Excessive salt intake

  • Thyroid dysfunction

  • Alcohol misuse

  • Obesity (risk and prognostic factor)

  • Excessive catecholamine states (e.g., from drug abuse or stress responses).


🧬 Pathophysiology of Acute Heart Failure

In AHF, the heart fails to maintain adequate output to meet systemic demands. This leads to a cascade of compensatory and pathological events:

Hemodynamic Changes

  • Increased ventricular filling pressures (right and left)

  • Depressed cardiac output and cardiac index

  • May have normal/increased CO in early stages with infection

Neurohormonal Activation

  • Sympathetic Nervous System activation → tachycardia, vasoconstriction, ↑ myocardial oxygen demand

  • Renin-Angiotensin-Aldosterone System (RAAS) → salt and water retention, worsening congestion

  • Increased wall stress → myocardial damage, further ↓ in perfusion

If untreated, these compensatory mechanisms:

  • Worsen fluid overload and pulmonary congestion

  • Impair renal perfusion

  • Lead to organ dysfunction

Reversibility

With prompt and appropriate treatment (e.g., BP control, relieving ischemia), myocardial function can sometimes recover, especially in reversible cases (e.g., ischemia-induced dysfunction).

Acute on Chronic Kidney Disease (AoCKD)

1. Impact of Chronic Kidney Disease (CKD)

CKD is a long-term condition where the kidneys gradually lose their ability to filter waste, balance fluids, and regulate electrolytes and hormones.

🧠 Physical Impact:

  • Uraemia: Buildup of waste products → nausea, confusion, pruritus

  • Electrolyte imbalances: Hyperkalaemia, hyponatraemia, acidosis

  • Fluid overload: Oedema, hypertension, pulmonary congestion

  • Anaemia: Due to decreased erythropoietin

  • Bone disease: From altered calcium and phosphate metabolism

  • Fatigue and reduced quality of life

  • Cardiovascular disease is the leading cause of death in CKD.

  • Hypertension both causes and worsens CKD.

  • Increased risk of infections and bleeding disorders.


2. What is Acute on Chronic Kidney Disease (AoCKD)?

Acute on Chronic Kidney Disease refers to: A sudden deterioration of kidney function in a person who already has chronic kidney impairment.

It often results from:

  • Dehydration or volume loss

  • Infections (e.g., sepsis, UTIs)

  • Nephrotoxic drugs (NSAIDs, contrast dye)

  • Obstructive uropathy (e.g., enlarged prostate)

  • Heart failure or hypotension

🩸 Clinical Signs:

  • Sudden rise in creatinine and urea

  • Oliguria or anuria

  • Fluid retention

  • Electrolyte disturbances (especially hyperkalaemia)

  • Possible mental status changes

Acute Kidney Injury (AKI)

What is Acute Kidney Injury (AKI)?

Acute Kidney Injury is: A sudden decline in kidney function, leading to an accumulation of waste products (urea, creatinine), disturbances in fluid, electrolyte, and acid-base balance, and decreased urine output.

AKI can develop within hours to days, and is often reversible if treated early.


Causes of AKI

Grouped into three main categories:

  1. Pre-renal (most common)

    • Due to reduced blood flow to the kidneys

    • Causes: dehydration, blood loss, heart failure, hypotension

  2. Intra-renal (intrinsic)

    • Due to direct damage to kidney tissues

    • Causes: acute tubular necrosis (ATN), nephrotoxic drugs, infections, glomerulonephritis

  3. Post-renal

    • Due to obstruction of urine flow

    • Causes: kidney stones, enlarged prostate, tumors


🔄 Three Phases of Acute Kidney Injury

🟥 1. Initiation Phase

  • Triggering event occurs (e.g., dehydration, sepsis, drug toxicity)

  • Subtle or no symptoms

  • Decrease in urine output may begin

  • Early intervention can prevent progression


🟨 2. Oliguric (or Maintenance) Phase

  • Occurs within 1–7 days of the insult

  • Urine output <400 mL/day

  • Symptoms:

    • Fluid overload (edema, crackles, hypertension)

    • Hyperkalaemia, metabolic acidosis

    • Uraemia (fatigue, nausea, confusion)

  • Labs: ↑ creatinine, ↑ BUN, ↑ potassium


🟩 3. Recovery (Diuretic) Phase

  • Gradual increase in urine output (up to 3–5 L/day)

  • Kidneys begin to recover

  • Monitor for dehydration and electrolyte loss

  • Eventually, renal function improves, but may not return to baseline

Here’s a detailed breakdown of the ABCDE approach to assessing a deteriorating patient, your role as a Registered Nurse (RN), when to begin a secondary assessment, and how to reflect on your learning needs.


ABCDE Approach for a Deteriorating Patient

The ABCDE framework is a structured, systematic method used to assess and treat life-threatening conditions in order of priority. It allows for early recognition, rapid intervention, and communication in clinical emergencies.


🅰 A – Airway

  • Is the airway open and patent?

  • Look for signs of obstruction: stridor, gurgling, use of accessory muscles

  • Interventions:

    • Perform a head-tilt, chin-lift (or jaw-thrust if trauma suspected)

    • Suction if needed

    • Insert airway adjuncts (e.g., oropharyngeal airway)

    • Escalate to medical team or MET (Medical Emergency Team) as required


🅱 B – Breathing

  • Assess respiratory rate, effort, SpO₂, chest symmetry

  • Look for: tachypnoea, cyanosis, reduced breath sounds

  • Interventions:

    • Administer oxygen if SpO₂ < 94% (or target range based on condition)

    • Position upright

    • Support with nebulisers or escalate for NIV/ventilation if needed


🅲 C – Circulation

  • Check heart rate, blood pressure, capillary refill, peripheral pulses

  • Look for signs of shock: cold, clammy skin, low urine output

  • Interventions:

    • Administer IV fluids if hypotensive (as per orders)

    • Obtain blood samples

    • Prepare for potential advanced life support (ALS)


🅳 D – Disability

  • Rapid neurological assessment using AVPU or GCS

  • Check pupils, blood glucose, and signs of seizure or confusion

  • Interventions:

    • Correct hypoglycaemia if glucose is low

    • Protect airway if altered consciousness

    • Escalate rapidly to senior clinicians


🅴 E – Exposure

  • Fully expose patient to examine for:

    • Rashes, injuries, signs of bleeding or infection

  • Check temperature

  • Preserve dignity and warmth after assessment


Role of the RN in ABCDE Assessment

  • Perform initial and ongoing assessments

  • Recognize early warning signs using tools like MEWS or NEWS2

  • Initiate immediate interventions within your scope (e.g., oxygen, fluids)

  • Escalate care as per hospital emergency protocols (e.g., MET call)

  • Document findings clearly and communicate using ISBAR

  • Support patient and family through reassurance and updates


When to Commence Secondary (Full Systems) Assessment?

You begin the secondary assessment after the patient is stabilized from the primary ABCDE assessment.
This includes:

  • Full head-to-toe assessment

  • Detailed history (AMPLE: Allergies, Medications, Past history, Last meal, Events leading up)

  • Focused assessments based on symptoms (e.g., chest pain → ECG, labs)

Do not delay treatment during primary assessment; treat as you go.

Absolutely! The DRSABCD acronym is a vital part of first response and basic life support. It’s a systematic approach used in emergency situations to assess and manage someone who has collapsed or is unresponsive. Let’s walk through each step:


🆘 DRSABCD – First Aid Response Framework

🔤 D – Danger Ensure the area is safe for yourself, the patient, and bystanders.

  • Look for hazards (e.g., electricity, fire, traffic, bodily fluids, sharp objects).

  • Don’t rush in—you can’t help if you become a victim yourself.


🔤 R – Response: Check if the person is responsive.

  • Gently shake their shoulders and shout:
    “Can you hear me?” “Open your eyes!”

  • Use AVPU:

    • Alert

    • Voice responsive

    • Pain responsive

    • Unresponsive

If they don’t respond → continue to the next step.


🔤 S – Send for Help

  • Ask a bystander to call immediately and get a defibrillator (AED) if available.

  • If alone: Call for help before starting CPR if the person is unresponsive and not breathing.


🔤 A – Airway: Open and check the airway.

  • Look for obstruction (tongue, vomit, food).

  • Use the head-tilt, chin-lift technique unless trauma is suspected.

  • If something is blocking the airway:

    • Roll the person onto their side (recovery position) and clear the mouth with a finger sweep if visible.


🔤 B – Breathing: Check if they are breathing normally.

  • Look: chest movement

  • Listen: for breath sounds

  • Feel: air from the nose/mouth on your cheek

Abnormal breathing (gasping) is not considered normal.

If not breathing or breathing abnormally → begin CPR.


🔤 C – CPR (Cardiopulmonary Resuscitation)

  • Push hard and fast in the centre of the chest (at least 5 cm deep)

  • Start CPR: 30 compressions : 2 breaths

  • Aim for 100–120 compressions per minute

  • Give 2 rescue breaths after every 30 compressions (if trained and able)

  • If not confident with breaths, continue with compression-only CPR

Keep going until help arrives, the person starts breathing, or you’re physically unable to continue.


🔤 D – Defibrillation:

  • Attach an AED as soon as possible (if available)

  • Turn it on and follow voice prompts

  • Ensure no one is touching the person when delivering a shock

  • Continue CPR between shocks if advised


🔁 Repeat the DRSABCD cycle as needed.
