Anaphylaxis

A severe, rapidly developing systemic hypersensitivity reaction that compromises the airway, breathing, or circulation. It is a medical emergency requiring immediate intramuscular adrenaline, high-flow oxygen, intravenous fluids, and urgent escalation of care.

Related: Adrenaline (Epinephrine), Airway Management, Shock
Adrenaline (Epinephrine)

A catecholamine drug that stimulates alpha and beta adrenergic receptors, raising blood pressure, dilating airways, and stabilising mast cells. First-line treatment for anaphylaxis and cardiac arrest; given intramuscularly in anaphylaxis and intravenously in resuscitation.

Related: Anaphylaxis, Cardiopulmonary Resuscitation
Airway Management

The sequence of manoeuvres and devices used to keep the upper airway open and oxygenate the patient, from head tilt and jaw thrust through supraglottic devices to endotracheal intubation. Assessed first in any deteriorating patient.

Related: Anaphylaxis, Glasgow Coma Scale, ABCDE Approach
ABCDE Approach

A structured primary survey prioritising Airway, Breathing, Circulation, Disability, and Exposure. Each element is assessed and treated before moving on, so immediately life-threatening problems are corrected in order of physiological priority.

Related: Airway Management, Glasgow Coma Scale, Sepsis
Glasgow Coma Scale

A 3-to-15 score summing eye, verbal, and motor responses to define level of consciousness. Scores of 8 or below generally indicate a need to secure the airway; serial scores track neurological deterioration.

Related: Airway Management, Stroke
Sepsis

Life-threatening organ dysfunction caused by a dysregulated host response to infection. Recognised by signs such as altered mentation, raised respiratory rate, low blood pressure, and elevated lactate, and treated with prompt antibiotics and fluid resuscitation.

Related: ABCDE Approach, Shock, Acute Kidney Injury
Shock

A state of inadequate tissue perfusion causing cellular hypoxia, classified as hypovolaemic, cardiogenic, distributive, or obstructive. Presents with hypotension, tachycardia, cool or warm peripheries, and altered consciousness; treatment targets the underlying cause.

Related: Sepsis, Anaphylaxis, Fluid Resuscitation
Fluid Resuscitation

Rapid administration of intravenous crystalloid or blood products to restore circulating volume in hypovolaemia, sepsis, or burns. Requires reassessment of response and awareness of overload risk, especially in cardiac or renal impairment.

Related: Shock, Sepsis, Acute Kidney Injury
Cardiopulmonary Resuscitation

Chest compressions and rescue breaths delivered to a patient in cardiac arrest to maintain circulation and oxygenation. High-quality compressions at the correct rate and depth, minimal interruptions, and early defibrillation determine survival.

Related: Adrenaline (Epinephrine), Airway Management
Acute Coronary Syndrome

A spectrum of myocardial ischaemia including unstable angina and myocardial infarction with or without ST elevation. Typically presents with central chest pain, sweating, and nausea; managed with aspirin, anticoagulation, and reperfusion where indicated.

Related: Electrocardiogram, Troponin, Heart Failure
Electrocardiogram

A recording of the heart's electrical activity used to detect arrhythmias, ischaemia, conduction blocks, and chamber enlargement. Interpretation follows a systematic sequence of rate, rhythm, axis, intervals, and ST-T changes.

Related: Acute Coronary Syndrome, Atrial Fibrillation
Atrial Fibrillation

An irregularly irregular supraventricular rhythm with absent P waves and variable ventricular rate. It raises stroke risk through atrial thrombus and is managed with rate or rhythm control plus anticoagulation based on assessed risk.

Related: Electrocardiogram, Stroke
Heart Failure

A clinical syndrome in which the heart cannot deliver sufficient output for metabolic demands or does so at raised filling pressures. Presents with breathlessness, fatigue, oedema, and raised natriuretic peptides; treated with diuretics and disease-modifying therapy.

Related: Acute Coronary Syndrome, Pulmonary Oedema
Pulmonary Oedema

Accumulation of fluid in the lung interstitium and alveoli, most often from left ventricular failure. Causes severe breathlessness, orthopnoea, crackles, and pink frothy sputum; treated with oxygen, diuretics, and vasodilators.

Related: Heart Failure, Respiratory Failure
Chronic Obstructive Pulmonary Disease

Persistent airflow obstruction from airway and parenchymal damage, usually related to tobacco smoke. Characterised by breathlessness, chronic cough, and exacerbations; managed with bronchodilators, inhaled corticosteroids in selected patients, and smoking cessation.

Related: Respiratory Failure, Asthma
Asthma

A chronic inflammatory airway disease with variable, reversible airflow obstruction and bronchial hyperresponsiveness. Presents with wheeze, cough, and episodic breathlessness; managed with inhaled corticosteroids and reliever bronchodilators.

Related: Chronic Obstructive Pulmonary Disease, Respiratory Failure
Respiratory Failure

Inability of the respiratory system to maintain adequate oxygenation or carbon dioxide clearance. Type 1 shows low oxygen with normal or low carbon dioxide; type 2 adds carbon dioxide retention, often requiring ventilatory support.

Related: Chronic Obstructive Pulmonary Disease, Pulmonary Oedema
Stroke

Sudden focal neurological deficit from vascular causes, either ischaemic infarction or haemorrhage. Time-critical assessment includes glucose, imaging, and thrombolysis or thrombectomy eligibility; atrial fibrillation is a major preventable risk factor.

Related: Atrial Fibrillation, Glasgow Coma Scale
Diabetes Mellitus

A group of metabolic disorders characterised by chronic hyperglycaemia due to insulin deficiency, insulin resistance, or both. Diagnosis uses fasting glucose, oral glucose tolerance testing, or HbA1c; management targets glycaemic control and complication screening.

Related: Diabetic Ketoacidosis, Hypoglycaemia
Diabetic Ketoacidosis

A metabolic emergency of insulin deficiency causing hyperglycaemia, ketonaemia, and metabolic acidosis. Presents with vomiting, abdominal pain, dehydration, and Kussmaul breathing; treated with fluids, insulin infusion, and careful potassium replacement.

Related: Diabetes Mellitus, Hypoglycaemia
Hypoglycaemia

An abnormally low blood glucose level, typically below 4 mmol/L, causing sweating, tremor, confusion, and seizures. Treated with fast-acting oral carbohydrate if conscious or intravenous glucose or intramuscular glucagon if not.

Related: Diabetes Mellitus, Diabetic Ketoacidosis
Acute Kidney Injury

An abrupt decline in kidney function reflected by rising creatinine or falling urine output. Causes are prerenal, renal, or postrenal; management focuses on restoring perfusion, stopping nephrotoxins, and relieving obstruction.

Related: Fluid Resuscitation, Sepsis
Hypertension

Persistently elevated arterial blood pressure, diagnosed by repeated clinic or ambulatory measurement. A major modifiable risk factor for stroke, ischaemic heart disease, and kidney disease; treated with lifestyle change and antihypertensive drugs.

Related: Stroke, Heart Failure
Troponin

A cardiac muscle protein released into blood when myocardial cells are damaged. High-sensitivity assays with serial sampling help diagnose myocardial infarction, though raised values also occur in other conditions.

Related: Acute Coronary Syndrome, Electrocardiogram
Consent

A patient's voluntary agreement to examination or treatment after receiving adequate information about benefits, risks, and alternatives. Requires capacity; treatment without valid consent may constitute battery or negligence.

Related: Capacity, Confidentiality
Capacity

The ability to understand, retain, weigh, and communicate a decision about a specific matter at a specific time. Assessed functionally; lacking capacity triggers best-interest decision-making rather than automatic assumption of incompetence.

Related: Consent, Confidentiality
Confidentiality

The professional duty to protect patient information from unauthorised disclosure. It may be overridden only with consent, by legal requirement, or in the public interest, and breaches must be justified and documented.

Related: Consent, Capacity
Prescription Safety

Practices that reduce medication error, including correct patient identification, dose calculation, allergy checking, legible documentation, and review of interactions. Particularly important for high-risk drugs such as anticoagulants, insulin, and opioids.

Related: Polypharmacy, Adverse Drug Reaction
Polypharmacy

The concurrent use of multiple medicines, often five or more, which raises the risk of interactions and adverse effects. Regular medication review and deprescribing where appropriate are core management steps.

Related: Prescription Safety, Adverse Drug Reaction
Adverse Drug Reaction

A harmful or unintended response to a medicine given at normal doses, classified as predictable (type A) or idiosyncratic (type B). Suspected serious reactions should be documented and reported to the national pharmacovigilance scheme.

Related: Prescription Safety, Polypharmacy
Informed Consent

Agreement obtained after a discussion covering the nature of the procedure, material risks, expected benefits, and reasonable alternatives including doing nothing. The standard is what a reasonable patient would want to know.

Related: Consent, Capacity
Differential Diagnosis

A working list of possible conditions that could explain a patient's presentation, ordered by likelihood and seriousness. It guides targeted history, examination, and investigation before the leading diagnosis is confirmed.

Related: Clinical Reasoning, Red Flag
Clinical Reasoning

The cognitive process of integrating history, examination, and test findings to form and test diagnostic hypotheses. It includes pattern recognition, probabilistic thinking, and explicit checks against cognitive bias.

Related: Differential Diagnosis, Red Flag
Red Flag

A symptom or sign indicating possible serious underlying disease that warrants urgent investigation or referral, such as weight loss, night pain, or new neurological deficit. Their presence overrides routine management pathways.

Related: Differential Diagnosis, Clinical Reasoning
Vital Signs

Measured physiological parameters including respiratory rate, oxygen saturation, heart rate, blood pressure, temperature, and consciousness level. Trends and early warning scores identify deterioration before overt clinical collapse.

Related: ABCDE Approach, Sepsis
Evidence-Based Medicine

The integration of best available research evidence with clinical expertise and patient values and preferences. It requires appraising study design, validity, and applicability rather than relying on tradition or authority alone.

Related: Clinical Reasoning, Differential Diagnosis
Medical Error

An act of omission or commission in planning or execution that contributes to or could contribute to unintended patient harm. Reporting and system analysis, rather than individual blame, drive safer practice.

Related: Prescription Safety, Adverse Drug Reaction
Referral

The process of transferring responsibility for part of a patient's care to another clinician or service with appropriate expertise. Effective referral communicates the clinical question, relevant findings, and urgency clearly.
