Using Nitrox

Scheduled for: 11 November 2026

Presenter: Lee Ingram

Summary: A practical introduction to enriched air nitrox, covering its benefits, depth limits and cylinder checks, with a live analyser demonstration.

Overview

This Staffordshire Divers club presentation explains what enriched air nitrox is, why divers use blends such as EAN32 and EAN36, and how the oxygen content affects no-stop time and maximum operating depth (MOD). A practical demonstration shows how to calibrate an analyser, sample a cylinder, record the oxygen reading and update the cylinder label. The session also covers oxygen exposure, equipment compatibility, dive computer setup and what nitrox training involves.

What the presentation covers

  • What enriched air nitrox is, including common blends such as EAN32 and EAN36
  • How nitrox affects nitrogen uptake, no-stop time and repetitive dive planning
  • Oxygen exposure and how the analysed mix determines maximum operating depth
  • Equipment compatibility, oxygen cleanliness and contamination
  • Live demonstration of analyser calibration, cylinder sampling, recording and labelling
  • Setting a dive computer to match the analysed mix and checking the limits for each dive
  • What to expect from nitrox training, including theory and practical skills

Who it is for

Club members who are new to nitrox, considering nitrox training or looking for a refresher.
