Online Respiratory Monitoring with the IRMA™ Sensor: Compact Performance for Intensive Care
The Masimo IRMA™ analyser stands out as a mainstream capnography device capable of meeting the most stringent clinical requirements. Weighing less than 25 grams and with a minimal footprint (38 x 37 x 34 mm), it fits seamlessly into respiratory circuits without disrupting patient ventilation. Its design allows for safe and reliable use even in the most fragile patients, such as newborns or patients on low-flow ventilation.
Unlike sidestream systems that sample gas, IRMA™ measures directly in-line in the breathing circuit. This technology significantly reduces response time, limits interference and preserves signal integrity, which is critical in environments where every second counts. With a start-up time of less than 10 seconds, it enables immediate monitoring, which is useful in emergency situations or in the operating theatre.
The IRMA CO₂ model provides direct, real-time measurement of exhaled and inhaled carbon dioxide using mainstream technology. Integrated directly into the breathing circuit, it does not sample gas, reducing measurement times and improving data accuracy. Its on-board spectrometer provides full accuracy in less than 10 seconds. It automatically compensates for temperature and pressure variations, ensuring reliable results regardless of clinical conditions.
A multi-coloured LED indicator allows immediate verification of the device status: green for a good connection, steady red for a sensor error, flashing red for an adapter problem, and blue when measuring an anaesthetic gas. This visual feedback facilitates maintenance in a clinical setting.
The IRMA™ also features ergonomic accessories, such as moisture-resistant hydrophilic adapters for adults, paediatrics and infants. A velcro fastener is also available for secure storage when the device is not in use.
Ideal for critical care environments, the IRMA™ guarantees reliable, continuous, real-time monitoring, in pure capnography or multi-gas analysis depending on the version selected. It is an effective solution for healthcare teams who want optimal control of respiration and anaesthetic agents, without compromising on compactness or speed.
