Tempus IC is intended to aid with the diagnosis of a person presenting as unwell or sick when they are in a location remote from immediate medical assistance. The device allows the User to take vital signs data from a patient and to transmit that data to medical professionals located at the response centre elsewhere. Typical examples are remote land, sea or air locations.

Tempus IC is intended primarily to be used by medically unqualified people who have received basic training in the use of the device. Medical expertise is provided through communication with the Response Centre which would be staffed by physicians who would advise the operator on the nature of the medical incident.

Tempus IC is intended to be used where a physician or other medically trained staff may or may not be present but where remote physician support is required.

Tempus IC is suitable for use on adults or children (over 10 years old and over 20kg in weight).

Device Description

The TempusIC™ is an advanced multi-parameter vital signs monitor designed for use in remote locations by trained non-expert users. It provides a wide range of features in a highly robust package, including integrated voice link and video camera.

Voice and data connections are made automatically via existing satellite or terrestrial communications systems.

The TempusIC™ is used in conjunction with TempusNET™ software, which provides a system for receiving real-time voice and vital signs data. The system enables users to receive voice, vital signs data, and still video pictures from TempusICTM devices located anywhere in the world.

The TempusNET™ system can be used by commercial response centre service providers or by individuals or organisations wishing to provide their own internal service.

It also provides a synchronised user interface, and remote control of the TempusIC™

TempusNET™ also supports a full patient records database.

AI/ML Overview

The provided text describes the TempusIC™ Patient Monitor, but it explicitly states that "Clinical tests have not been performed" to prove the efficacy of the measurement techniques. Therefore, there is no study described in this document that proves the device meets specific acceptance criteria based on clinical performance.

Instead, the submission relies on the following:

Substantial Equivalence: The device is claimed to be substantially equivalent to previously cleared predicate devices (Tempus 2000 Patient Monitor, K033410 & K0443 (note: K0443 is likely a typo for K04436 as per the text)).
OEM Modules: All medical modules and sensors used in the TempusIC™ have prior 510(k) clearance and are used as intended by their manufacturers.
Bench and Performance Testing: Functions and features additional to the measurement of medical parameters have been tested by bench and performance testing.
Desat Study: A "conventional desat study" was carried out to verify that the performance of the combined PCB and probe were within specification. However, the details of this study, its acceptance criteria, or its results are not provided.
User Evaluations: User evaluations were conducted to confirm ease-of-use, not clinical performance.
Conformity to Essential Principles: Evidence of conformity to GHTF guidance (GHTF/SG1/N14R9:2005 and SG1/N011: 2008) is cited, including performance testing, software validation, electrical safety, electromagnetic compatibility, and risk analysis. Again, specific performance acceptance criteria and results are not detailed.

Given this, I cannot provide a table of acceptance criteria and reported device performance based on clinical studies, nor can I provide information on sample sizes, ground truth establishment, expert qualifications, or MRMC studies for clinical performance, as these were explicitly not performed.

However, based on the information provided, here's what can be inferred about the type of justification used for device performance:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (Inferred from Text)	Reported Device Performance (Inferred from Text)
Medical Parameter Measurement Efficacy:
* Accurate vital signs measurement	* Not independently proven by clinical tests for the TempusIC™ itself. The claim is based on the use of "currently available (OEM) technology found in many legally marketed devices" and the assertion that the "Tempus 2000 is effectively identical to the devices that incorporate the same OEM technology" (referring to the predicate device). All OEM medical modules and sensors have prior 510(k) clearance and are used as intended.
Functional/Feature Performance (non-medical parameter):
* Proper operation of integrated voice link, video camera, data connection	* "The functions and features of the TempusIC™ that are additional to the measurement of medical parameters have been tested and proven by bench and performance testing." (No specific results or acceptance criteria provided in the summary.)
Combined PCB and Probe Performance (for desaturation):
* Performance within specification during desaturation	* "a conventional desat study was carried out to verify that the performance of the combined PCB and probe were within specification." (No specific "specification" or results provided.)
Ease of Use:
* Meets ease-of-use design objective for trained non-experts	* "User evaluations have been carried out with representative groups of professional, non-professional but trained, and untrained users, to confirm the ease-of-use design objective has been met." (No specific metrics or results provided.)
Software Conformance:
* Adherence to FDA's Guidance for Premarket Submissions for Software	* "The requirements of the FDA document Guidance for the Content of Premarket Submissions for Software contained in Medical Devices have been applied."
* Adherence to IEC 60601-1-4	* "In addition, the requirements of IEC 60601-1-4 have been addressed."
Safety and Performance (General):
* Conformity to GHTF essential principles	* "The device has been shown to conform to the essential principles for safety and performance defined in guidance prepared by the Global Harmonization Task Force Study Group1 (GHTF/SG1/N14R9:2005)... evidence includes performance testing, software validation, electrical safety, electromagnetic compatibility, and risk analysis." (No specific results provided.)
* Comparable to predicate device	* "On the basis of these results and the above referenced testing, it is our determination that the device is safe, effective and performs as well as, or better than, the legally marketed predicate device(s)." (This is a conclusion, not specific performance data.)

2. Sample size used for the test set and the data provenance:
As clinical tests for efficacy were not performed, there is no "test set" in the sense of patient data for clinical performance evaluation. The "desat study" mentioned is vague on sample size and provenance. User evaluations involved "representative groups," but the size is not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable, as clinical tests were not performed. For user evaluations, "professional, non-professional but trained, and untrained users" were involved, but their number and specific qualifications (beyond "professional" or "trained") are not detailed.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable, as clinical tests were not performed.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
No, an MRMC study was not done. The device description does not involve AI or reader interpretation in that context. The system involves remote medical staff interpreting data and advising operators, but this is not an MRMC study on device performance.

6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done:
The device itself is a "standalone monitor" in its basic use, but its full intended use involves human interpretation of its transmitted data by medical professionals. Since no clinical performance study was done for the device as a whole, it's not possible to describe a standalone algorithm-only performance study.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
Not applicable for clinical performance, as clinical tests were not performed.
For the "desat study," the "specification" serves as a form of ground truth, but its origin and specific values are not presented.
For user evaluations, the "ease-of-use design objective" was the ground truth, assessed by user feedback.

8. The sample size for the training set:
Not applicable, as no algorithm requiring a training set for clinical performance is detailed. Data collected by the device would be for patient monitoring, not for training a predictive algorithm within the device for clinical decision-making.

9. How the ground truth for the training set was established:
Not applicable, as no training set is described.

Device Description

Voice and data connections are made automatically via existing satellite or terrestrial communications systems.

The TempusNET™ system can be used by commercial response centre service providers or by individuals or organisations wishing to provide their own internal service

{1}------------------------------------------------

It also provides a synchronised user interface, and remote control of the TempusIC™

TempusNET™ also supports a full patient records database.

Intended Use

The Tempus/C™ Patient Monitor is intended to be used when a medical situation arises at a location remote from readily available medical expertise. Situations demanding use of the TempusIC™ Patient Monitor can occur at remote land locations on private vachts while sailing at considerable distances from land, and during flight on commercial /private jets as well as in other situations.

The TempusIC™ Patient Monitor is intended to be used by trained non-experts upon people presenting as unwell. It is designed with the most ease of use for the operator so that it can be used quickly, reliably, with minimum training and with little or no support from medical staff. This allows the TempusIC™ Patient Monitor to be used as either a stand-alone monitor or also connected to the TempusNET™ server system.

In the latter mode, the TempusIC™ Patient Monitor connects through TempusNET™ server system to a sister device, called the TempusNET™ monitoring station allowing the recorded data to be viewed, stored and manipulated by trained medical staff.

The TempusNETTM monitoring station comprises a normal, commercial grade PC which is dedicated to running the software that enables it to communicate with the TempusIC TM Patient Monitor. The TempusNET™ monitoring station is installed at a Response Centre (typically an emergency room within a hospital) and is operated by experts from the hospital staff.

The operator at the Response Centre is able to receive voice calls and data on the patient's condition for assessment and consequently advise on an appropriate course of action. Such action may include advice on treatments to stabilize the condition, or instructions to return to land or divert from the planned journey, if the patient is at sea or in the air.

Indications for Use

RDT Tempus IC Patient Monitor 510k Summary of Safety and Effectiveness

Tempus IC is intended to be used where a physician or other medically trained staff may or may not be present but where remote physician support is required.

Tempus IC is suitable for use on adults or children (over 10 years old and over 20kg in weight).

Predicate Devices

The TempusIC has been shown to be substantially equivalent to the Tempus 2000 Patient Monitor, which was the subject of two previous submissions (K033410 & K404436).

K 010436

Operation of the new device is essentially the same in terms of medical and Operation of the notion, but the TempusIC™ employs the latest hardware and software technology and materials to provide a more compact and robust unit. The TempusIC™ has been tested to the same standards as the predicate monitor.

All of the OEM medical modules and sensors used in the TempusIC™ have 510(k) clearance, and are used as intended by their manufacturers.

Evidence of Conformity to Essential Principles

The device has been shown to conform to the essential principles for safety and performance defined in guidance prepared by the Global Harmonization Task Force Study Group1 (GHTF/SG1/N14R9:2005), with supporting evidence prepared in the summary technical documentation (STED) format recommended in final version of GHTF guidance (SG1/N011: 2008).

Specifically, this evidence includes performance testing, software validation, electrical safety, electromagnetic compatibility, and risk analysis, where third party testing has been conducted, if appropriate.

The design of this device utilises currently available (OEM) technology found in many legally marketed devices. In terms of measurement performance, the Tempus 2000 is effectively identical to the devices that incorporate the same OEM technology.

Software

The requirements of the FDA document Guidance for the Content of Premarket Submissions for Software contained in Medical Devices have been applied. In addition, the requirements of IEC 60601-1-4 have been addressed.

User Evaluations

User evaluations have been carried out with representative groups of professional. non-professional but trained, and untrained users, to confirm the ease-of-use design objective has been met.

RDT Tempus IC Patient Monitor 510k Summary of Safety and Effectiveness

Clinical Tests

Clinical tests have not been performed as all of the medical devices are currently cleared to market in applications that are individually substantially equivalent to the intended use of each medical parameter within the TempusIC™. Consequently, the use of clinical investigations to prove the efficacy of the measurement techniques was otherwise not required.

The functions and features of the TempusIC™ that are additional to the measurement of medical parameters have been tested and proven by bench and performance testing. In addition to bench testing of the various parameters, a conventional desat study was carried out to verify that the performance of the combined PCB and probe were within specification.

Conclusion

On the basis of these results and the above referenced testing, it is our determination that the device is safe, effective and performs as well as, or better than, the legally marketed predicate device(s).

This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.
