Medical-surgical units are challenged by low nurse-to-patient ratios, increasing case complexity and variability. Clinicians have long understood the value of monitoring in helping to alleviate these burdens, but previous solutions for this environment have been intermittent, delayed and/or limited in their effectiveness. Masimo has developed integrated monitoring technologies providing noninvasive and continuous measurements that automate and streamline the flow of patient data to improve clinical efficiency.

The ability to continuously monitor active patients in medical-surgical units reliably – and to save clinicians’ time by documenting important physiological measurements in electronic medical records – allows clinicians to spend more time caring for patients.

Masimo offers an integrated portfolio of solutions designed to help clinicians focus on patients and improve workflows, including industry-leading SET® pulse oximetry, advanced measurement capabilities, vital signs monitors, portable monitoring devices, and a robust remote monitoring and clinician notification system.

The Challenges of Alarm Fatigue

Clinicians rely on patient monitors to alert them of adverse changes in a patient’s condition. Alarm fatigue – the sensory overload of an excessive number of alarms – can, however, result in desensitization to alarms and missed alarms, as well as patient discomfort.

Masimo SET® Measure-through Motion and Low Perfusion™ Pulse Oximetry

Masimo’s breakthrough Signal Extraction Technology® (SET®) overcomes the limitations of conventional pulse oximetry with the ability to measure through motion and low perfusion.

Two separate studies found that Masimo SET® pulse oximeters detected approximately 10 times more true events than other "Next Generation" pulse oximeters studied.1,2

Performance During Motion and Low Perfusion3

Masimo - Performance During Motion and Low Perfusion

Masimo SET® had 3% missed true alarms and 5% false alarms versus 43% and 28%, respectively, using competitor technology.3

Results shown are calculated by combining sensitivity and specificity outcomes of machine-generated and volunteer-generated motion.

In another study which compared the ability of three pulse oximetry technologies to detect hypoxic events, Masimo SET® pulse oximetry demonstrated the highest sensitivity and specificity during induced conditions of motion and low perfusion.3

Helping Improve Outcomes in Medical-Surgical Units with Patient SafetyNet


In an 11-month study conducted at Dartmouth-Hitchcock Medical Center, Dr. Andreas Taenzer and colleagues found that using Masimo Patient SafetyNet™* and Masimo SET® pulse oximetry as part of a comprehensive alarm management strategy reduced rescue events by 65% and intensive care unit transfers by 48%, and as a result, reduced costs by $1,480,000.4,5 In a subsequent article, they announced that after five years, Dartmouth-Hitchcock had had zero preventable deaths or instances of brain damage due to opioids since the installation of Patient SafetyNet.5 In 2016, after ten years, they reported achieving a 50% reduction in unplanned ICU transfers and a 60% reduction in rescue events, despite increases in patient acuity and occupancy.6

Noninvasive Real-time Measurements

Masimo technology includes a host of noninvasive measurements offered through many patient monitoring solutions, enabling care areas such as the medical-surgical unit, which cater to a variety of patient cases and populations, to customize the type and degree of monitoring needed.

  • The rainbow SET™ upgradable technology platform provides measurements and physiologic parameters such as total hemoglobin (SpHb®), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®),  and oxygen content (SpOC™) to provide deeper insight into a patient’s status.
  • rainbow Acoustic Monitoring® enables monitoring of respiration rate utilizing the unique vibrations associated with breathing for a patient-tolerant7 alternative to capnography.
  • NomoLine™ sidestream capnography and gas monitoring provides integrated ventilation monitoring with a wide variety of sampling lines for both intubated and non-intubated patients.
  • Noninvasive blood pressure and temperature are integrated into multiple Masimo monitors, offering comprehensive vital signs monitoring, including quick spot-checking during rounds when using optional roll stands.
  • Early Warning Score (EWS) calculations provide greater insight into patient status, arming clinicians with more information to help make appropriate care decisions.8

Innovations in Respiration Rate Monitoring: rainbow Acoustic Monitoring®

The Anesthesia Patient Safety Foundation (APSF)9 and The Joint Commission recommend continuous oxygenation and/or ventilation monitoring for patients receiving opioid-based pain medications.10 However, current methods of respiration rate monitoring may be limited by shortcomings related to accuracy and patient tolerance.11,12 rainbow Acoustic Monitoring provides a noninvasive, continuous, easy-to-use, and reliable monitoring solution that has the benefit of higher patient tolerance.13,14

Root® is a powerful, expandable patient monitoring and connectivity hub that integrates an array of technologies to provide multimodal monitoring and connectivity solutions – in a single, clinician-centric platform that allows clinicians to tailor monitoring solutions for high- and low-acuity settings. Root’s plug-and-play expansion capabilities, as well as its availability in a configuration with integrated noninvasive blood pressure and temperature, allow clinicians to centralize patient monitoring by bringing together advanced rainbow SET™ Pulse CO-Oximetry, vital signs measurements, brain function monitoring, regional oximetry, and capnography measurements on an easy-to-interpret, customizable display, empowering clinicians with more information. Further, Root serves as a central connectivity hub, with automated electronic charting of Masimo and third-party device data and alarms to electronic medical record (EMR) systems, which may improve clinician workflows through the reduction of manual data documentation.

Device Integration

Root has the unique ability to bring together data and alarms from multiple third-party monitors — such as IV pumps, ventilators, and other multi-parameter monitors — automating the flow of patient data to the EMR, which may help streamline workflows, improve productivity, and reduce the likelihood of transcription errors.15

Bedside Patient Association to Facilitate Positive Patient Association

Masimo - Med-Surg - Bedside Patient Association

Used in conjunction with Patient SafetyNet or Iris Gateway™, Clinicians receive ADT information directly on Root, facilitating positive patient identification. Clinicians simply select a patient from a drop-down list or scan the patient’s wristband using an optional barcode scanner, attached to Root, to associate the patient, device, and clinician at the bedside.


The Radius-7® Pulse CO-Oximeter® is a Bluetooth®-enabled wearable monitor used in conjunction with the Root patient monitoring and connectivity platform. Radius-7 provides continuous tetherless monitoring so that patients can ambulate throughout the hospital and have freedom of movement while being continuously monitored. Two "hot-swappable," rechargeable modules with up to 12-hour battery life minimize monitoring interruption and require just one module exchange per shift. The use of single-patient-use armbands minimizes the risk of patient cross contamination.
