Cloud (Dual) Prong

Delivers O₂ to both nostrils while sampling CO₂ from both simultaneously. Ideal for longer sedation cases and patients with inconsistent nasal breathing patterns - captures a reliable waveform regardless of which nostril dominates.

Split (Bifurcated) Prong

Delivers O₂ through one nostril, samples CO₂ from the other. The separated gas pathways produce a cleaner, undiluted CO₂ reading - the standard configuration for oral surgery, endoscopy, and most AAOMS-compliant sedation monitoring setups.

Male Luer

Connector

The most common configuration. Plugs directly into the sampling port on most sidestream ETCO2 monitors, including Criticare, Philips, and Nihon Kohden. Choose this if you know your monitor accepts a standard male luer input.

Female Luer

Connector

Required by monitors and adapters with a male-port output. Same tubing and prong quality - just the opposite end fitting. If your current cannula supplier ships female connectors, this is your direct replacement.

Universal vs Std

O2 Connector

Two ways to connect to your oxygen supply. Standard is a friction-fit funnel that slides on fast - great for quick room turns. Universal is a threaded fitting that locks on securely. Choose universal for longer cases or setups where tubing gets moved around.

etco2 monitoring starts with a clean, reliable sampling path

An ETCO2 nasal sampling cannula is designed to do two jobs at once - deliver supplemental oxygen while continuously sampling exhaled carbon dioxide to a sidestream capnography monitor. ETCO2 reflects the carbon dioxide measured at the end of exhalation and is commonly expressed in mmHg, with normal values typically around 35 - 45 mmHg. Because capnography provides both a numeric reading and a real-time waveform, it remains one of the most widely used tools for monitoring ventilation during sedation and anesthesia.

The goal is straightforward - consistent oxygen delivery, dependable CO2 sampling, and a setup your team can match to the monitor, room layout, and procedure type without unnecessary guesswork. Endure ETCO2 cannulas are available in multiple prong styles, connector types, tubing lengths, and specialty configurations to support common sidestream monitoring workflows.

The right configuration helps protect signal quality, workflow efficiency and confidence chairside.

What AAOMS requires in Sedation

If you manage an OMS practice, here is what you need to understand about capnography compliance

Sidestream vs. Microstream Capnography

There are two main technologies: sidestream and Microstream. Here's what you need to know.

Capnography for Dental Sedation

The shift toward required capnography in dental sedation began with the AAOMS mandate in 2014...

bench-tested in simulated settings

Endure ETCO2/O2 cannulas were evaluated in simulated bench testing against a predicate device for ETCO2-equivalent measurement, oxygen-connector integrity, and FiO2 consistency across controlled flow conditions.

Normal ETCO2 Range

35 - 45 mmHg

Typical normal ETCO2 reference range

Tested Oxygen Flows

2 / 4 / 6 LPM

Oxygen flow settings used in ETCO2-equivalent bench testing

Comparison Result

± 2 mmHg

Reported Endure-vs-predicate ETCO2-equivalent measurements were within ±2 mmHg across the tested flow settings.

Connector Integrity

No Leakage Detected

Bubble air leak testing reported no leakage for the proposed device or the predicate device under the study conditions.

In-vitro simulated testing only. Not a clinical study. No waveform analysis was performed. FiO2 testing also reported results consistent with oxygen flow rate and identical to the predicate device under test conditions.

frequently asked questions

Can I try them before committing to a full order?

Yes. We ship free samples of any cannula variant - split prong, cloud prong, male connector, female connector, universal connector, 7ft, 14ft, adult, or pediatric. No minimum purchase, no commitment, no follow-up pressure. Most practices test on 3 - 5 patients before placing their first case order. Email orders@endureind.com with your practice name, shipping address, and monitor model, and we'll send samples within a few business days.

Will these work with my capnography monitor?

Endure ETCO2 cannulas are compatible with all standard sidestream capnography monitors, including Criticare, Edan, Philips (non-Microstream models), Nihon Kohden, BCI, and Nonin. If your monitor uses a standard luer sampling port, our cannulas will work. The one exception is Microstream monitors (Medtronic) - those require proprietary FilterLines and are not compatible with any standard ETCO2 cannula. Not sure which technology your monitor uses? Email us your monitor model and we'll confirm compatibility before you order.

How are these so much cheaper than Salter Labs?

The product is the same category - FDA-registered, medical-grade, Class II ETCO2 nasal sampling cannulas with appropriate laboratory testing & 510k registration. The price difference is structural, not quality-related. Salter Labs and Teleflex sell through distributors (Henry Schein, Medline, Bound Tree) who each add 20 - 40% margin. We sell direct to your practice — no middleman, no GPO administrative fees, no brand markup. Same function, same regulatory standards, roughly half the cost.

What's your return policy?

If you're not satisfied for any reason, we offer a full refund within 30 days of purchase. No restocking fees, no complicated process. We'd rather you try the product with zero risk than wonder whether it's worth switching. That said, our return rate is extremely low - most practices that test our cannulas don't go back to what they were using before.

How quickly do orders ship?

In-stock orders ship same day if placed before 12 PM ET. Most domestic orders arrive within 24 hours. Free shipping on all orders over $75 - which is just two cases. For recurring needs, many practices set up standing monthly orders so they never run low.

What's the difference between split prong and cloud prong?

Split (bifurcated) prong delivers oxygen through one nostril and samples CO2 from the other. It's the most widely used configuration and the standard for AAOMS-compliant sedation monitoring. Cloud (dual) prong delivers oxygen to both nostrils while sampling CO2 from both simultaneously. It produces a more consistent waveform in patients who breathe unevenly or during longer cases. Most practices start with split prong. If you're not sure, we'll include both styles in your sample kit so your team can compare.

How do I know which connector type to order?

Check the CO2 sampling port on your monitor. If the port is a hollow receptacle, you need a male luer connector. If it has a protruding tip, you need a female luer connector. If you have multiple monitors across rooms or you're simply not sure, order our universal connector - it fits both. One SKU, every room, zero guesswork.
