Device Description

The Datex-Ohmeda Tonometry Module, M-TONO (later referred to as M-TONO) is a module used to monitor gastrointestinal PCO2. The user interface has been implemented in the main software of the AS/3 and CS/3 monitoring systems.

The Datex-Ohmeda Tonometry Module, M-TONO is intended to be used with a Datex-Ohmeda Modular monitoring systems for gastrointestinal tonometry measurements.

This device is indicated for use by qualified medical personnel only.

M-TONO is a single-width plug-in parameter module including the tonometry measurement module for a modular monitoring system. This module is designed for use in the following Datex-Ohmeda modular monitors: AS/3 Anesthesia Monitor, AS/3 Compact Monitor, CS/3 Compact Monitor and CS/3 Critical Care Monitor.

The tonometry module measures the gastrointestinal PCO2 (PgCO2) every 10 minutes utilizing a tonometry catheter placed into the patient's stomach or intestine. Initially the module fills the balloon of the Tonometrics catheter with ambient air, then repeatedly every 10 minutes deflates the balloon, analyzes and displays the PgCO2, and inflates the balloon again.

AI/ML Overview

The provided text is a 510(k) Premarket Notification summary for the Datex-Ohmeda Tonometry Module, M-TONO. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than providing detailed studies proving the device meets specific acceptance criteria in terms of diagnostic performance (like sensitivity, specificity, accuracy).

Therefore, based only on the provided text, a comprehensive answer to your request cannot be fully generated. The document primarily discusses:

General company and device information
Device description and intended use
Comparison to a predicate device (Tonocap™ Monitor, K962638), highlighting similarities in intended use and differences in form factor (module vs. standalone), ability to measure higher PgCO2, and smaller measurement volume.
Compliance with electrical safety standards.

There is no information in the provided text regarding:

Specific quantitative acceptance criteria for device performance (e.g., accuracy, precision for PgCO2 measurement).
A dedicated study proving the device meets such acceptance criteria.
Sample sizes for test sets, data provenance, expert involvement, adjudication methods, MRMC studies, or standalone performance studies related to diagnostic accuracy.
Details on training sets or how ground truth was established for performance evaluation.

The "summary of nonclinical testing" only mentions compliance with safety standards (IEC 60601-1, CAN/CSA C22.2 No. 601-1-M90, IEC 60601-1-2, IEC 60601-1-4), electrical safety, electromagnetic compatibility, mechanical and environmental tolerance, and software validation. It does not outline performance criteria for measuring PgCO2.

The conclusion states, "The summary above shows that there are no questions of safety and effectiveness for the Datex-Ohmeda Tonometry Module, M-TONO as compared to the predicate device," which is the standard conclusion for a 510(k) submission showing substantial equivalence, not a direct demonstration of meeting predefined performance acceptance criteria through a specific study.

To answer your request based strictly on the provided text, I must state that the requested information (acceptance criteria for performance metrics and a study proving their fulfillment) is not present in this 510(k) summary. The document focuses on substantial equivalence based on intended use, technological characteristics, and conformance to safety standards.

DEVICE DESCRIPTION as required by 807.92(a)(4)

The Datex-Ohmeda Tonometry Module, M-TONO is intended to be used with a Datex-Ohmeda Modular monitoring systems for gastrointestinal tonometry measurements.

This device is indicated for use by qualified medical personnel only.

INTENDED USE as required by 807.92(a)(5)

The Datex-Ohmeda Tonometry Module, M-TONO is intended to be used with a Datex-Ohmeda Modular monitoring systems for gastrointestinal tonometry measurements.

It is indicated for use in hospital patients.

SUMMARY OF TECHNOLOGICAL CHARACTERITICS OF DEVICE COMPARED TO THE PREDICATE DEVICE as required by 807.92(a)(6)

The Datex-Ohmeda Tonometry Module, M-TONO is substantially equivalent to the legally marketed (predicate) Tonocap™ Monitor (K962638). Based on the analysis and other documentation included in this 510(k) notification and attachments it is evident that the main features and indications for use of Datex-Ohmeda Tonometry Module, M-TONO is substantially equivalent to the predicate Tonocap™ Monitor (K962638).

The Datex-Ohmeda Tonometry Module, M-TONO and TONOCAP™ monitor (K962638) have the same intended use for gastrointestinal PCO2 monitoring.

The Datex-Ohmeda Tonometry Module, M-TONO and TONOCAP™ monitor (K962638) are indicated for monitoring gastrointestinal PCO2 (PgCO2) and calculation of various gastrointenstinal tonometry parameters. Both are indicated for use in hospital patients. The Datex-Ohmeda Tonometry Module. M-TONO uses Tonometrics catheters, which have separate 510(k) clearances, similar to those used by the predicate TONOCAP™ monitor (K962638).

The main differences between M-TONO and the predicate is primarily due to fact that M-TONO is a module used in modular system while predicate TONOCAP™ monitor (K962638) is a standalone configured monitor. Additionally, airway gas measurement is not made with M-TONO since another module in the AS/3 and CS/3 family already handles this function.

The M-TONO module can also measure higher PgCO2 than the predicate TONOCAP™ monitor (K962638).

The M-TONO module uses a smaller PgCO2 measurement volume than predicate TONOCAPTM monitor (K962638).

It is evident that the Datex-Ohmeda Tonometry Module, M-TONO is substantially equivalent to the predicate TONOCAP™ Monitor (K962638).

The comparison above shows that there are no questions of safety and effectiveness for the Datex-Ohmeda Tonometry Module, M-TONO.

{3}------------------------------------------------

SUMMARY OF NONCLINICAL TESTING FOR THE DEVICE and CONCLUSIONS as required by 807.92(b)(1)(3)
