For years, the bedside standard for confirming a nasogastric tube has been a single check: aspirate pH. It works — when you can get a sample, and when the reading is clear. But pH alone tells you about acidity, not about whether the tube has strayed toward the airway.

So, we asked a simple question: what if you could check two things during the insertion?

DoubleCHEK combines two indicators in one bedside device:

• CO₂ detection — a sign the tube tip may be in the airway rather than the oesophagus, giving an early warning during placement.
• pH indication — confirming the tube tip is in the acidic environment of the stomach.

Two key checks, one safe placement. No special tubes, no capital equipment — it works with all standard ENFit feeding and decompression tubes, using a procedure familiar to anyone who’s done bedside aspiration.

One device, designed to a single standard of care and cleared for use across three major markets: UKCA marked for the UK, CE marked across the EU, and FDA 510(k) cleared in the US.

It’s not about replacing clinical judgement. It’s about giving clinicians more of the information they need, at the moment they need it.

(Always follow your local placement protocol and IFU.)
