React Right & O2 Provider

React Right is the foundational emergency response course in the SSI system, covering CPR and basic first aid in a format designed for divers but applicable well beyond diving contexts. It’s a practical course — the emphasis is on developing skills you can actually use under pressure, not on passing a written exam.

The course covers adult CPR and rescue breathing, recognising and responding to common diving-related emergencies, managing a conscious or unconscious casualty at the surface, and basic first aid for the kinds of injuries that can occur in an aquatic environment. Scenarios are kept realistic and relevant — the course assumes you might actually need to use these skills one day and prepares you accordingly.

React Right is the entry point before React Right & O2 Provider for divers who want to add oxygen administration to their skillset, and a standalone certification for those who want solid emergency response skills without the oxygen component. It’s also a recommended prerequisite for the Diver Stress & Rescue course alongside the O2 Provider qualification.

For any diver spending significant time in the water — whether diving regularly on Koh Tao or traveling to dive destinations — having a current first aid and CPR certification is simply good practice. React Right provides that certification in a format that takes a day and produces skills that last.
