((If trainees do not apply oxygen within 2 minutes of assessment, SpO2 drops to 88% and patient becomes more agitated and distressed โ prompt trainee: 'The patient grips the chair and says he cannot catch his breath.'))
((If trainees attempt to administer salbutamol without a spacer, facilitator informs them the EHS MDI spacer device is available at the FAP โ direct trainee to use Space Chamber or Lite Aire spacer as per CPG.))
((If trainees do not reassess the patient after the first salbutamol dose at 20 minutes, prompt: 'The patient says his chest still feels very tight and the wheeze has not improved much โ what do you do next?'))
((If trainees do not request ambulance/higher-care backup for a severe exacerbation with SpO2 <92%, facilitator states: 'Your FAP supervisor asks whether this patient needs escalation โ what is your decision?'))
((If trainees ask about using the patient's own puffer without a spacer, remind them the preferred route is MDI via spacer โ patient's own medication may be used but via EHS spacer device.))
This patient is suffering from a severe acute asthma exacerbation.
- Ensure scene safety and don appropriate PPE.
- Perform Primary Survey โ confirm patent airway, severe breathing difficulty, circulation intact, GCS 15.
- Position patient upright or in position of comfort โ do not lay flat.
- Apply oxygen via simple face mask at 5โ8 L/min โ titrate SpO2 to target 92โ95% for adults.
- Perform Vital Sign Survey โ RR, SpO2, HR, BP, pain score.
- Conduct SAMPLE history โ confirm asthma diagnosis, current medications, triggers, prior hospitalisations or ICU admissions.
- Assess severity of exacerbation using severity classification โ wheeze, accessory muscle use, sentence completion, SpO2 โ classify as SEVERE.
- Administer Salbutamol (Ventolin) 400โ1200 microg (4โ12 puffs) via MDI and spacer โ indication: bronchospasm in acute asthma.
- Reassess after each 4-puff administration โ monitor RR, SpO2, wheeze, ability to speak in full sentences.
- Repeat Salbutamol 400โ1200 microg (4โ12 puffs) via MDI and spacer every 20 minutes or sooner if clinically indicated.
- Request ambulance/higher-level backup given severe classification and SpO2 <92% on room air โ this is a time-critical patient.
- Record full observations every 10 minutes (or 5 minutes given time-critical status).
- Continuously reassure patient and keep exertion minimal.
- Prepare for rapid deterioration โ have BVM and suction immediately available.
- Do NOT ventilate unless patient loses ability to maintain adequate respiratory effort โ if required, ventilate gently at no more than 4โ6 breaths per minute to avoid air trapping.
- Scenario ends on arrival of ambulance and IMISTAMBO handover.
- Attention to hand hygiene will be given throughout the scenario.
