Pneumonia Emergency Care: EMT Guide

Pneumonia in Emergency Care: Assessment, Oxygen, Sepsis and Treatment

Pneumonia can deteriorate quickly. Infection and inflammation fill alveoli with fluid, pus or cellular debris, reducing oxygen transfer and increasing the work of breathing. A patient may progress from cough and fever to hypoxaemic respiratory failure, sepsis, septic shock, empyema or acute respiratory distress syndrome. EMT care therefore combines infection precautions, ABCDE assessment, oxygen and ventilatory support, appropriate antimicrobials, fluid balance, nursing surveillance and prevention. Apply the current Uganda Clinical Guidelines, local antimicrobial policy and senior clinical direction.

1. Learning objectives

Define pneumonia and distinguish community-acquired, healthcare-associated, aspiration, atypical and opportunistic patterns.
Recognise severe pneumonia, hypoxaemia, sepsis, shock and impending respiratory failure.
Perform a focused history, examination and ABCDE assessment.
Describe oxygen, bronchodilator, fluid, antibiotic, antiviral and ventilatory-support principles.
Plan nursing care, monitoring, referral, discharge education and prevention.

2. What is pneumonia?

Pneumonia is infection and inflammation of the lung parenchyma, especially the alveoli. Bacteria, viruses, fungi and occasionally parasites may cause it. The alveoli fill with inflammatory fluid, impairing ventilation–perfusion matching. Pneumonia may be mild and treated orally, or severe enough to require oxygen, IV medicines, intensive care and mechanical ventilation.

Pattern	Typical context	Emergency concerns
Community-acquired	Begins outside hospital or early after admission.	Pneumococcal disease, influenza/COVID, sepsis and respiratory failure.
Healthcare-associated/hospital-acquired	Recent admission, procedure, healthcare exposure or ventilator.	Resistant organisms, device infection and rapid deterioration.
Aspiration	Vomiting, dysphagia, stroke, seizures, reduced consciousness or tube feeding.	Airway obstruction, chemical pneumonitis, anaerobic infection and abscess.
Opportunistic	HIV, immunosuppression, cancer, malnutrition or prolonged steroids.	Atypical organisms, hypoxaemia with few chest signs and need for specialist care.

3. Causes and risk factors

Bacterial pathogens, respiratory viruses, tuberculosis, fungal infection and mixed infection.
Age under five or over 65, pregnancy, HIV, diabetes, sickle-cell disease, malnutrition, COPD/asthma, heart/renal disease and cancer.
Smoking, biomass fuel, air pollution, overcrowding, poor vaccination, immobility and recent influenza-like illness.
Recent antibiotics or hospitalisation, aspiration risk, feeding tubes, poor dentition and impaired cough.

4. Clinical features

Domain	Findings	Red flags
Symptoms	Cough, sputum, fever/chills, pleuritic pain, dyspnoea, fatigue.	Rapid worsening, inability to speak/drink, haemoptysis, severe chest pain.
Breathing	Tachypnoea, crackles, bronchial breathing, reduced expansion, hypoxaemia.	Severe work, cyanosis, exhaustion, silent chest, falling consciousness.
Circulation/sepsis	Tachycardia, fever/hypothermia, delayed refill, weakness.	Hypotension, mottling, oliguria, confusion or lactate elevation.
Children	Fast breathing, chest indrawing, poor feeding, grunting, lethargy.	Apnoea, inability to drink, cyanosis, convulsions or severe malnutrition.
Older/immunocompromised	Confusion, falls, weakness or no fever may predominate.	New delirium, low temperature, subtle hypoxaemia or rapid functional decline.

5. History and differential diagnosis

Onset, fever pattern, cough, sputum colour/volume, dyspnoea, pleuritic pain, haemoptysis and exposure.
Recent hospitalisation, antibiotic use, tuberculosis contact, COVID/influenza exposure, aspiration event or travel.
Baseline exercise tolerance, COPD/asthma, heart failure, HIV, diabetes, pregnancy, vaccination and allergies.
Consider pulmonary embolism, heart failure, asthma/COPD exacerbation, pneumothorax, TB, malaria, anaemia, sepsis from another source and foreign body.
Ask about swallowing, vomiting, seizures, stroke, alcohol/sedative use and dental disease when aspiration is possible.

6. Triage and ABCDE

Step	Assess	Act
A – Airway	Secretions, aspiration, reduced consciousness, obstruction.	Suction, position, airway adjunct if trained, prepare advanced support.
B – Breathing	Rate, effort, speech, expansion, crackles, SpO₂ and fatigue.	Oxygen to target, upright position, bronchodilator if bronchospasm, ventilatory escalation.
C – Circulation	Pulse, BP, perfusion, dehydration, urine and shock.	IV access, cultures if feasible, cautious crystalloid, sepsis pathway and monitoring.
D – Disability	AVPU/GCS, glucose, delirium, seizures.	Check glucose, protect airway, treat seizures and escalate for encephalopathy.
E – Exposure	Temperature, rash, wounds, oedema, calf signs and pressure areas.	Prevent heat loss, inspect for source, isolate respiratory disease and preserve dignity.

Immediate senior review: severe hypoxaemia, respiratory rate above the local danger threshold, shock, new confusion, apnoea, cyanosis, inability to drink, multilobar disease, pregnancy, infant/neonate, immunosuppression or failure to respond to initial treatment.

7. Oxygen and respiratory support

Give oxygen immediately for hypoxaemia, respiratory distress or shock, using the prescribed target and device.
Reassess SpO₂, respiratory effort, mental state and gas exchange after each change; a normal saturation on high oxygen can hide severe disease.
Use nasal cannula, face mask, non-rebreather, high-flow nasal oxygen, CPAP/NIV or invasive ventilation according to severity and facility capability.
Escalate for rising oxygen requirement, exhaustion, severe acidosis, altered consciousness or inability to protect the airway.
Position upright, clear secretions, encourage effective cough and prevent aspiration.

8. Investigations

Serial vital signs, pulse oximetry, glucose, urine output and perfusion assessment.
Chest radiograph or ultrasound for consolidation, oedema, effusion, abscess or pneumothorax.
FBC, renal/electrolytes, glucose, liver tests, lactate and blood gas when severe or septic.
Blood cultures before antibiotics when feasible without dangerous delay; sputum culture for severe, recurrent, resistant or treatment-failure disease.
Viral testing, TB assessment, HIV testing and malaria evaluation according to local epidemiology and symptoms.
Do not delay oxygen, resuscitation or antibiotics while waiting for imaging or culture in a deteriorating patient.

9. Medical treatment

9.1 Antimicrobials

Use protocol-based empiric antibiotics for likely bacterial pneumonia, especially severe disease or sepsis; choice depends on community/hospital setting, age, allergy, pregnancy, renal function and local resistance.
Use oral therapy for stable, mild disease when absorption is reliable; IV therapy is considered for severe illness, shock, vomiting, altered consciousness or poor absorption.
Review cultures and clinical progress daily, narrow or stop treatment when appropriate, and document the planned duration and switch criteria.
Antibiotics do not treat uncomplicated viral pneumonia; consider antiviral therapy when indicated by the current pathogen-specific guideline.

9.2 Supportive treatment

Give antipyretic and analgesia safely, maintain hydration and nutrition, and avoid fluid overload in heart/renal failure.
Use bronchodilator only when bronchospasm is present; wheeze does not automatically mean asthma.
Manage sepsis with prompt cultures, antibiotics, cautious fluids, source control and vasopressor/critical-care escalation if shock persists.
Drain empyema/abscess, treat obstructive disease and seek surgical review for complicated aspiration or perforation.

10. Sepsis and shock from pneumonia

Recognise infection plus new organ dysfunction: confusion, hypotension, hypoxaemia, oliguria, mottling, rising lactate or respiratory failure.
Place in a monitored resuscitation area, obtain IV access, check glucose, take cultures if feasible and start the sepsis pathway.
Give appropriate antimicrobials promptly; reassess after each fluid bolus for perfusion, lung crackles, oxygen need and urine output.
Escalate for vasopressor support, high-flow oxygen, NIV or ventilation when indicated.
Communicate using SBAR and pre-alert a higher-level facility if oxygen, imaging, surgery or critical care is unavailable.

11. Nursing care plan

Problem	Interventions	Evaluate
Impaired gas exchange	Upright position, oxygen, suction, respiratory observations, aspiration precautions.	SpO₂ target, effort, rate, mental state, ABG and oxygen trend.
Hyperthermia/pain	Temperature chart, prescribed antipyretic/analgesic, light clothing and comfort.	Temperature, pain, rigors and response.
Reduced perfusion	Fluid balance, IV therapy, urine measurement, shock chart and escalation.	BP, pulse, refill, skin, mentation, lactate and urine.
Retained secretions	Hydration assessment, coached cough, oral care, suction and physiotherapy referral.	Air entry, sputum, work of breathing and aspiration risk.
Transmission risk	Hand hygiene, masks/PPE, respiratory isolation and equipment cleaning.	Correct precautions and no cross-infection.

12. Special populations

Children: assess feeding, interaction, chest indrawing, grunting, respiratory rate and weight-based therapy; severe cases need urgent referral.
Neonates: poor feeding, temperature instability, apnoea or lethargy may be the only signs; treat as high risk.
Pregnancy: maternal hypoxaemia threatens the fetus; involve obstetric and respiratory teams early.
Older adults: confusion or falls may precede fever and cough; review polypharmacy and frailty.
HIV/immunosuppression: consider TB, Pneumocystis and atypical infection; localise early specialist input.

13. Complications and monitoring

Respiratory failure, ARDS, sepsis, septic shock, acute kidney injury and encephalopathy.
Parapneumonic effusion, empyema, lung abscess, necrotising pneumonia and pneumothorax.
Arrhythmia, myocarditis, myocardial infarction, delirium, malnutrition and pressure injury.
Monitor observations, oxygen requirement, urine, fluid balance, glucose, renal function, mental status and treatment response.
Escalate for worsening oxygen need, new confusion, hypotension, reduced urine, exhaustion or persistent fever despite treatment.

14. Discharge and prevention

Discharge only when oxygenation, work of breathing, hydration, mental state and oral intake are stable with a clear follow-up plan.
Complete prescribed therapy, demonstrate inhaler/oxygen use and explain return signs: worsening breathlessness, blue lips, confusion, chest pain, persistent fever or inability to drink.
Promote pneumococcal/influenza/COVID vaccination as locally recommended, smoking cessation, clean cooking fuel, hand hygiene and good nutrition.
Prevent aspiration with safe feeding position, swallowing assessment, oral care and review of sedatives.
Teach families to seek care early for fast breathing, chest indrawing, cyanosis or poor feeding in children.

15. Clinical scenarios

Scenario 1 – severe community pneumonia. A 62-year-old has fever, RR 34/min, SpO₂ 82%, confusion and BP 88/54. Give oxygen, ABCDE, IV access, glucose check, cultures if feasible, prompt protocol-based antibiotics, cautious fluid reassessment and urgent critical-care referral.

Scenario 2 – aspiration. After a seizure, a patient coughs, desaturates and has coarse crackles. Protect the airway, suction, oxygenate, assess for obstruction/aspiration, keep nil by mouth until safe and obtain urgent senior review.

Scenario 3 – child with severe pneumonia. A 2-year-old has chest indrawing, grunting, poor feeding and lethargy. Treat as severe disease: oxygen, glucose, weight-based medication, warmth, urgent referral and continuous observation.

Scenario 4 – pneumonia mimic. Sudden unilateral chest pain, absent breath sounds and hypotension suggests tension pneumothorax rather than ordinary pneumonia. Treat the immediate life threat and escalate for urgent decompression.

16. Common errors to avoid

Waiting for an X-ray or culture before treating hypoxaemia, shock or suspected sepsis.
Giving unlimited fluid to a patient with heart/renal failure or pulmonary oedema.
Using antibiotics without indication, culture review or a stop/switch plan.
Missing TB, aspiration, pulmonary embolism, heart failure or pneumothorax.
Ignoring subtle deterioration in older adults, neonates or immunocompromised patients.
Discharging without safety-net advice, prevention counselling and follow-up.
