Device Description

The Mortara Surveyor S12 and S19 are integrated multi-parameter patient monitors designed to be used by trained medical personnel within healthcare facilities on adult, adolescent, child, infant, and neonatal patient populations.

Surveyor S12 and S19 include color, touch screen displays which present patient demographics, physiological waveforms, numeric data, trends, status condition, with high, medium, and low warning alarms and technical messages. The monitor alerts of patient conditions with audible alarming through a speaker located within the device, visual alarms presented on the graphical user interface, and a visual LED alarm bar indicator on the front of the unit. The monitor provides a dedicated ON/OFF switch with AC power LED indication. Power is provided either from an external power supply connected to mains, or an internal lithium-ion battery. The Surveyor S12 has an 11.6" display and comes with an integrated 2 channel printer, while the Surveyor S19 has at 18.5"display and comes with an optional 2 channel printer.

The Surveyor S12 and S19 are intended for continuous monitoring in both bedside and portable applications and are manufactured in various fixed configurations. A Surveyor S12 or S19 may include the following parameters: 3, 5, or 10 Wire electrocardiography (ECG), 12 lead resting ECG, impedance respiration, non-invasive blood pressure (NIBP), up to two temperatures, functional arterial oxygen saturation (SpO₂), up to four invasive blood pressures (IBP), end-tidal & inspired CO2, and thermal dilution cardiac output.

The Surveyor S12 and S19 may be used as stand-alone monitors near the patient bedside, or during patient transport within a healthcare facility. When connected to the Mortara Surveyor Network, the Surveyor S12 and S19 can be part of a centralized monitoring system managed by the Surveyor Central Station (K131929) which can also send data to the Electronic Health Record. The Surveyor Central displays the aforementioned parameters including audible and visuals alarms.

AI/ML Overview

1. Table of Acceptance Criteria and Reported Device Performance

ParameterAcceptance Criteria (Not Explicitly Stated for all, but Inferred from Standards)Reported Device Performance (from Clinical Study for Neonatal NIBP)
Neonatal NIBP Safety & EffectivenessCompliance with ISO 81060-2:2013 and ISO 14155:2011Clinical study conducted to demonstrate safety and effectiveness
Other Parameters (ECG, SpO2, etc.)Compliance with various IEC/ISO standards (e.g., IEC 60601 series, ISO 9919, etc.)Not explicitly detailed in the provided text

2. Sample Size Used for the Test Set and Data Provenance

The provided text only explicitly mentions a clinical study for the neonatal non-invasive blood pressure (NIBP) readings.

  • Neonatal NIBP Clinical Study Test Set:
    • Sample Size: Not specified in the provided text.
    • Data Provenance: Not specified (e.g., country of origin, retrospective or prospective). However, the study was conducted to demonstrate safety and effectiveness for the neonatal patient population, implying prospective data collection specifically for this purpose.

For other parameters (e.g., ECG, SpO2), no specific test set sample sizes or data provenance are detailed. The substantial equivalence relies on compliance with various international standards, which typically involve testing against predefined datasets or clinical scenarios.

3. Number of Experts and Qualifications for Ground Truth Establishment

This information is not provided in the given text for any aspect of the device's evaluation. The clinical study for neonatal NIBP refers to the demonstration of safety and effectiveness, but it does not detail the method for establishing ground truth or the involvement of experts in that process.

4. Adjudication Method for the Test Set

This information is not provided in the given text.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A multi-reader multi-case (MRMC) comparative effectiveness study was not conducted (or at least, not mentioned) for the Mortara Surveyor S12 and S19 Patient Monitor based on the provided text. The submission focuses on demonstrating substantial equivalence to predicate devices through technical comparisons and compliance with standards, and a single clinical study for one specific parameter (neonatal NIBP).

6. Standalone Performance Study

Yes, a standalone performance study was done for the neonatal Non-Invasive Blood Pressure (NIBP) readings. A clinical study was conducted to demonstrate the safety and effectiveness of these readings. The wording suggests that the device's performance for this specific function was evaluated independently.

For other parameters (like ECG, SpO2, etc.), the document primarily references compliance with various IEC and ISO standards (e.g., IEC 60601 series), which typically involve standalone testing of the algorithm or device's performance against defined benchmarks or simulated signals. The results of these tests, however, are not explicitly provided in the summary.

7. Type of Ground Truth Used

For the neonatal NIBP clinical study, the type of ground truth used is not explicitly stated. However, clinical studies designed to demonstrate safety and effectiveness, as mandated by ISO 81060-2:2013 (which specifies clinical investigation of automated measurement type sphygmomanometers), typically rely on:

  • Simultaneously obtained reference measurements: Often from an "expert" or gold-standard measurement method (e.g., invasive arterial blood pressure monitoring for NIBP), or highly accurate manual measurements by trained observers using auscultation. The standard sets strict requirements for how these reference measurements are taken and compared.

For other parameters, the ground truth would be established by the respective standards they comply with (e.g., standardized ECG waveforms for arrhythmia detection, calibrated SpO2 simulators, etc.).

8. Sample Size for the Training Set

This information is not provided in the text. The document describes a clinical study for neonatal NIBP for validation/testing, not for training. Given the device's nature as a physiological monitor relying on established algorithms and hardware, it's less likely to involve a "training set" in the machine learning sense for its core functionalities, but rather calibration and verification against known signals or reference measurements during development.

9. How Ground Truth for the Training Set Was Established

As no training set is described or implied in the provided text, information on how its ground truth was established is not applicable/not provided.

§ 870.1025 Arrhythmia detector and alarm (including ST-segment measurement and alarm).

(a)
Identification. The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.(b)
Classification. Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document.
