Compare the Masimo EMMA Capnograph and EMMA Airway Adapter to understand their distinct roles in capnography monitoring. Learn which device fits your airway management needs.
Quick Answer
The Masimo EMMA Capnograph is a portable monitor that measures exhaled CO2, while the EMMA Airway Adapter is a single-use accessory that connects the monitor to the patient's airway. You need both for continuous capnography, but they serve different roles in your setup.
Why the distinction matters for airway management
Capnography is essential for assessing ventilation in both field and hospital settings. The Masimo EMMA Capnograph provides continuous end-tidal CO2 readings, but it cannot function without a compatible airway adapter to sample the patient's breath. Understanding the difference between the monitor and its accessory helps you budget, stock, and train correctly.
Trade-off: Reusable monitor vs. disposable adapter
The capnograph is a durable, reusable device that you purchase once and use across multiple patients. The airway adapter is designed for single-patient use to reduce cross-contamination risk, meaning you need to replenish adapters regularly. This ongoing cost is a key consideration for departments with high patient volume or limited budgets.
Key Differences at a Glance
- Primary function: The capnograph measures and displays CO2 levels; the adapter samples gas from the airway.
- Reusability: The capnograph is a reusable device; the adapter is single-use only. Factor adapter replenishment into your supply budget.
- Compatibility: The adapter is intended for use with compatible EMMA capnography devices, so verify your monitor model before purchasing.
Product Facts
- Masimo EMMA® Capnograph: The Masimo EMMA Capnograph is a portable monitoring device that provides continuous measurement of exhaled carbon dioxide. It gives clinicians real-time ventilation status, making it critical for confirming tube placement and monitoring breathing during transport or procedures.
Masimo EMMA® Capnograph - Masimo EMMA® Airway Adapter: The Masimo EMMA Airway Adapter is designed for single-patient use to help reduce cross-contamination risk. You must stock adapters separately, and each patient requires a fresh adapter, which adds to per-use cost but improves infection control.

Which Should You Choose?
Best for
- Teams that already own a capnograph and need a steady supply of single-use adapters for infection control.
- Clinicians who want a portable, continuous end-tidal CO2 monitor for field or hospital use.
Not for
- Users who expect the adapter to function as a standalone monitor—it requires the capnograph device.
- Budget-conscious buyers who overlook the recurring cost of single-use adapters.
