Emergency Medical Services

For paramedics, emergency medical technicians, and first responders, medical assessments and interventions are often made in challenging conditions. Masimo Pulse CO-Oximetry technology and capnography solutions enable first responders to quickly assess patients, monitor patients during transport, and alert hospitals of incoming patient status, so that staff can prepare the space, personnel, and equipment needed for appropriate and timely care transitions.

Fast, Reliable Pulse Oximetry

Fast, Reliable Pulse Oximetry


Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry delivers accurate and reliable oxygen saturation (SpO2), pulse rate (PR), and perfusion index (Pi) measurements even during challenging conditions of motion and low perfusion, as frequently presented during on-scene patient assessment and emergency transport.

Monitoring for Carbon Monoxide Levels in the Blood with SpCO®

Monitoring for Carbon Monoxide Levels in the Blood with SpCO®


rainbow SET™ technology is a platform of noninvasive measurements and physiologic parameters that can provide deeper insight into a patient’s status. SpCO, Masimo’s original rainbow® parameter, measures carboxyhemoglobin, which forms in red blood cells upon exposure to carbon monoxide (CO).

Carbon monoxide (CO) is a colorless, odorless and tasteless gas that is largely undetectable by humans and is often unknowingly inhaled from combustion fumes and during fires by victims and first responders. CO, when bound to hemoglobin in red blood cells, reduces the oxygen carrying capacity. The National Fire Protection Association (NFPA)’s Fire Rehabilitation Standard recommends that firefighters exposed to smoke at incident scenes and during training be assessed for elevated CO levels on the scene. SpCO allows clinicians to noninvasively assess CO levels in the blood.

Rapid On-Scene Assessment with Advanced Handheld Devices

Rapid On-Scene Assessment with Advanced Handheld Devices


Masimo’s versatile portable device solutions provide capnography and advanced rainbow SET measurements in lightweight, compact, yet rugged handheld devices for quick on-site vital signs assessment and monitoring during inter-facility transport.

Masimo - Easy to use Rad-57® handheld Pulse CO-Oximeter®

Rad-57® is an easy-to-use, handheld Pulse CO-Oximeter® with the ability to measure key physiologic parameters – including noninvasive measurement of hemoglobin (SpHb®), carboxyhemoglobin (SpCO) and methemoglobin (SpMet®) in addition to SET® SpO2, PR and Pi –with results in just a few simple steps and the ability to store up to 72 hours of trend data. 

Masimo - MightySat® Rx fingertip pulse oximeter to feature Masimo SET®

MightySat® Rx is the first fingertip pulse oximeter to feature Masimo SET®, providing quick spot-checking of SpO2, PR, Pi, and optionally pleth variability index (PVi®) in an exceptionally portable device. Measurements can be quickly communicated to and tracked and stored on compatible smart devices using Bluetooth®.

iPhone not included.

Masimo - EMMA™ is a compact, portable, lightweight, mainstream capnograph

EMMA™ is a compact, portable, lightweight, mainstream capnograph that requires minimal warm-up time and provides full accuracy in 15 seconds. EMMA is available for short- and long-term monitoring of adults, pediatrics, and infants. Clear, real-time EtCO2 waveforms help clinicians and first responders confirm effective resuscitation, assess the depth and effectiveness of compressions, and recognize the return of spontaneous circulation (ROSC).1,2

Flexible, Versatile Sensor Solutions

Flexible, Versatile Sensor Solutions


Masimo provides a variety of single-patient-use and reusable sensor solutions for patients of all ages, including sensors designed to facilitate high-volume, rapid monitoring, sensors designed to stay securely in place in challenging conditions, and sensors designed for monitoring sites less susceptible to changes in peripheral perfusion.

Masimo - E1® ear sensor

The single-patient-use E1® ear sensor is designed for secure placement in the cavum conchae, combining Masimo SET® performance with an alternative monitoring site easily accessible even during emergency situations.

Masimo - Complete TFA-1™ forehead sensor

The single-patient-use TFA-1™ forehead sensor is designed for monitoring on the forehead, which may have faster detection of desaturation and resaturation, as compared to digit sensors.3 Like the ear, the forehead may also be more easily accessible than other monitoring sites during emergency situations.
