The optional Masimo Radical-7 Pulse CO-Oximeter and Accessories are indicated for the continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total hemoglobin concentration (SpHb), and/or respiratory rate (RRa). The Masimo Radical-7 Pulse CO-Oximeter and accessories are indicated for use with adult, pediatric, and neonatal patients during both no motion conditions, and for patients who are well or poorly perfused in hospitals, hospital-type facilities, mobile, and home environments. In addition, the Masimo Radical-7 Pulse CO-Oximeter and accessories are indicated to provide the continuous non-invasive monitoring data obtained from the Masimo Radical-7 Pulse CO-Oximeter and accessories of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate to multi-parameter devices for the display of those devices. The optional Masimo Radius-7 Wearable Pulse Oximeter and Accessories are indicated for the continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, and/or respiratory rate (RRa). The Masimo Radius-7 Wearable Pulse Oximeter and accessories are indicated for use with adult, and pediatric patients during both no motion and motion conditions, and for patients who are well or poorly perfused in hospitals, and hospital-type facilities. The optional ISA product family consists of three types of sidestream gas analyzers (ISA CO2, ISA AX+ and ISA OR+), intended to be connected to other medical backboard devices for monitoring of breath rate and the following breathing gases: ISA CO2: CO2 ISA AX+: CO2, N2O, Halothane, Isoflurane, Enflurane, Sevoflurane and Desflurane ISA OR+: CO2, O2, N2O, Halothane, Isoflurane, Enflurane, Sevoflurane and Desflurane ISA CO2, ISA AX+ and ISA OR+ are intended to be connected to a patient breathing circuit for monitoring of inspired/expired gases during anesthesia, recovery and respiratory care. The intended environment is the operating suite, intensive care unit and patient room. ISA CO2 is also intended to be used in road ambulances. The intended patient population is adult, pediatric and infant patients. The optional SEDLine Sedation Monitor is indicated for use in the operating room (OR), intensive care unit (ICU), and clinical research laboratory. It is intended to monitor the state of the brain by real-time data acquisition and processing of EEG signals. The system includes the Patient State Index (PSI), a proprietary computed EEG variable that is related to the effect of anesthetic agents. The optional temperature module is indicated to measure temperature (oral, adult axillary, pediatric axillary, and rectal) of adult and pediatric patients. The device is intended to be used by clinicians and medically qualified personnel. It is available for sale only upon the order of a physician or licensed health care provider.

# Device Description - Disease/Conditions that Device Diagnose, Treat, Prevent, Cure or Mitigate, Including Patient Population

The Root Monitoring System (Root) is a multifunctional device that monitors vital signs of patients from neonates to adults. Parameters monitored by Root include non-invasive functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate, carboxyhemoglobin saturation (SpCO), methemoglobin saturation (SpMet), total hemoglobin concentration (SpHb), respiratory rate (RRa), inspired/expired gases during anesthesia, recovery and respiratory care, state of the brain by real-time data acquisition and processing of EEG signals, temperature, non-invasive blood pressure (NIBP) and Patient State Index (PSI) which is an EEG variable that is related to the effect of anesthetic agents.

# Explanation of Why Differences in Indication Statement Are Not Critical to Intended Use, and Why Difference Do Not Affect Safety and Effectiveness of Device When Used as Labeled

Root is intended to be used with the previously FDA cleared measurement technologies for the modules of:

- External Masimo Radical-7 Pulse CO-Oximeter (Radical-7 module), with cleared . technologies of SpO2, pulse rate, SpCO, SpMet, SpHb and RRa monitoring per K110028.
- . External Masimo Radius-7 Pulse Oximeter (Radius-7 module), with cleared technologies of SpO2, pulse rate and RRa monitoring per K110028.
- . External ISA-Infrared Sidestream Gas Analyzer (ISA module), with cleared technologies of breathing gases and respiratory rate monitoring per K103604.
- External Sedline Sedation Monitor with Frontal PSI and SEDTrace EEG Electrode Set (Sedline module), with cleared technologies of EEG and PSI monitoring per K051874.
- . Internal temperature module, with cleared temperature measurement technologies (the module was integrated in the Welch Allyn Spot Ultra Vital Signs/Welch Allyn Spot Vital Signs LXi per K101680).
- Internal non-invasive blood pressure (NIBP) module with cleared NIBP measurement . technologies (the module was integrated in Zoll R Series per K090989).

Root is also intended to be used as a user interface to facilitate access control and monitoring device functions and to connect system networks such as the Patient SafetyNet (K071047).

# Device Description - General Description from Labeling, Including Explanation of How Device Functions, Scientific Concepts that Form Basis For the Device

Root displays patient monitoring information from the connected modules. Visual alarms are shown on the Root display and audible alarms are generated through the Root internal speaker. The user accesses the connected modules' monitoring functions, using the Root

{7}------------------------------------------------

display. When the module is disconnected from Root, the monitoring information from the module is no longer displayed on Root.

Data from connected modules, including patient monitoring data, can be communicated to network systems. Root also functions as a pass-through means for communicating information between connected devices and network systems.

The subject device is the same as the primary predicate (K142394). The main difference is that the subject device has been modified to integrate internal modules for temperature and NIBP measurement technologies.

# Technological Characteristics

#### Principle of Operation

Root functions as a user interface that allows access, control and monitoring from the connected modules (external and internal).

Data from connected modules, including patient monitoring data, can be communicated to network systems. Root also functions as a pass-through means for communicating information between connected devices and network systems.

### Mechanism of Action for Achieving the Intended Effect

Root communicates with connected modules and displays the modules' patient monitoring information on the Root display. The healthcare provider controls the functions of each module using the Root touchscreen display. Visual alarms are shown on the Root display and audible alarms are generated through the Root internal speaker.

By connecting external modules or devices to Root, data can be communicated between Root and network systems via wired or wireless connection. Information from network systems can be shown on the Root display for viewing and notification purposes.

Once use is complete, the user then turns the power "off" for Root.
