About Dr. Osei

Dr. Marcus Osei is a Consultant in Emergency Medicine at Erasmus MC Rotterdam, one of the Netherlands’ leading academic medical centres. With 12 years of experience in high-acuity emergency medicine, he has used every stethoscope — from basic ward instruments to premium cardiology models — in the most time-critical clinical environments imaginable: trauma bays, resuscitation rooms, triage corridors and aeromedical transport.

At Stethoscope24, Marcus writes about what stethoscopes actually need to deliver when seconds count. His articles cut through the noise and focus on real-world clinical performance under pressure — because in emergency medicine, there is no time for a second listen.
