Carbon monoxide with a reassuring monitor
Educational use only. Not clinically reviewed36-year-old man for calm hidden-hypoxia recognition, escalation, selected-patient consultation, reassessment, and handoff practice. About 6 simulated minutes.
What you will practise
- Reconcile the shared exposure, clock, syncope, symptoms, conventional pulse oximetry, and whole patient.
- Recognize a carbon-monoxide pattern despite reassuring pulse oximetry and without single-value closure.
- Activate source safety, qualified oxygen, monitoring, and poison-center and emergency ownership.
- Review supplied co-oximetry and the neurologic, cardiac, and severity boundary.
- Record selected-patient hyperbaric consultation, then reassess a strict later report.
- Hand off delayed neurologic, cardiac, exposure, follow-up, and active risk.
