1) Initial Phase

ECG: Sinus Tachycardia HR: 120 SBP: 90 DBP: 60 RR: 24 SpO₂: Normal Waveform @ 92% ETCO₂: Bronchoconstriction @ 40mmHg 12 Lead: https://12s.medsim.app/sinus-tach.webp ECG After Shock: Asystole

2) Improving Phase

Trigger: Administration of Epinephrine Description: Patient's breathing eases, wheezing diminishes. Consciousness improves. Intervention Context: Epinephrine is the first-line treatment for anaphylaxis. Consider fluid resuscitation and monitoring vital signs closely.

ECG: Sinus Tachycardia HR: 110 SBP: 110 DBP: 70 RR: 20 SpO₂: Normal Waveform @ 96% ETCO₂: Normal Waveform @ 38mmHg 12 Lead: https://12s.medsim.app/sinus-tach.webp ECG After Shock: Asystole

3) Worsening Phase

Trigger: Delayed or insufficient treatment Description: Patient develops hypotension and altered mental status. Wheezing worsens. Intervention Context: Delayed epinephrine administration allows for progression of anaphylaxis. Consider airway management and immediate fluid resuscitation.

ECG: Sinus Tachycardia HR: 130 SBP: 70 DBP: 40 RR: 28 SpO₂: Low Perfusion @ 88% ETCO₂: Bronchoconstriction @ 45mmHg 12 Lead: https://12s.medsim.app/sinus-tach.webp ECG After Shock: Asystole
