The intended use of the M4 Monitor is for the non-invasive continuous monitoring of O2 saturation, hematocrit and haemoglobin concentration, blood flow, gaseous emboli, Temperature, PO2, and PCO2, in an extracorporeal circuit.

The device provides monitoring information to trained clinicians and can be configured by them to set parameter specific alarms.

Device Description

The Spectrum M4 Monitor consists of a 10.4 inch high definition touch screen and sensor assemblies connected to a flat panel display unit. Optical sensor assemblies are used to collect data for the measurement of Arterial and Venous Saturation and Hot / Hb. Ultrasonic sensors are used to collect data for the measurement of flow and gaseous emboli. A thermistor is used for the collection of temperature data. Inlet and outlet gas measurements sensors are used to collect data for the measurement of PO2, and PCO2.

Parameter values are displayed in both a digital and trended format. The M4 Monitor has been designed to self-detect the selected sensor and to automatically configure the required parameter display screens. The device can be configured by the trained clinician to set parameter specific alarms and to select either the display of hematocrit or haemoqlobin concentration. Session data can be stored to a memory card supplied with the system, via a RS232 link or wirelessly to a remote computer.

The M4 Monitor is powered from the AC Mains supply and also incorporates a battery back-up that automatically switches on in the event of an interruption to the mains power supply. The system weighs 4.5 kg and is supplied with a pole mount clamp.

AI/ML Overview

The provided text K110957 describes a medical device called the "M4 Monitor" and its substantial equivalence to predicate devices, but it does not contain any information about specific acceptance criteria, study details, sample sizes, ground truth establishment, or multi-reader multi-case studies.

The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting detailed performance study results with acceptance criteria.

Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor can I answer the specific questions regarding sample sizes, ground truth, expert qualifications, adjudication methods, or MRMC studies for the M4 Monitor based on the provided text.

The closest information available is a general statement about performance:

"Performance data has been provided to show that the revised M4 Monitor can measure the oxygen saturation, hematocrit / haemoglobin concentration, blood flow, gaseous emboli, Temperature, PO2, and PCO2."

This statement confirms that performance data was provided to the FDA, but the content of that data, including specific acceptance criteria or study methodologies, is not detailed in this 510(k) summary.

Predicate Devices:

Spectrum Medical - M3 Monitor. K091908

Description of Proposed Device:

Parameter values are displayed in both a digital and trended format. The M4 Monitor has been designed to self-detect the selected sensor and to automatically configure

the required parameter display screens. The device can be configured by the trained clinician to set parameter specific alarms and to select either the display of hematocrit or haemoqlobin concentration. Session data can be stored to a memory card supplied with the system, via a RS232 link or wirelessly to a remote computer.

Intended Use of Proposed Device

The intended use of the M4 Monitor is for the non-invasive continuous monitoring of O2 saturation, hematocrit and haemoglobin concentration, blood flow, gaseous emboli, Temperature, PO2, and PCO2.

The device provides monitoring information to trained clinicians and can be configured by them to set parameter specific alarm levels.

Substantial Equivalence Determination &Technological Characteristics

Oxygen Saturation, Hematocrit / Haemoglobin Concentration, Flow & Emboli:-

The proposed device has the same technological characteristics and measurement performance as the predicate M3 monitor cleared under 510(k) K091908. Both monitor and sensor designs remain unchanged between the proposed device and the predicate M3.

Temperature PO2 & PCO2 :-

For the measurement of Temperature, PO3 & PCO2 the proposed device as the same intended use as the CDI monitor cleared under 510(k) K972962 in that key measurements are made in the extracorporeal circuit during Cardiac Surgery or ECMO life support. The major difference in the technological characteristics of the proposed device and the predicate CDI 500 device is that the proposed device is completely non-invasive while the predicate device involves the use of a sterile cuvette inserted into the blood tubing.

Performance Information

The M4 Monitor has an intended use that is featured in its two predicate devices. Performance data has been provided to show that the revised M4 Monitor can measure the oxygen saturation, hematocrit / haemoglobin concentration, blood flow, gaseous emboli, Temperature, PO2, and PCO2.

The M4 Monitor is therefore considered substantially equivalent to its predicate devices.

Dear Mr. Rongero:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
