The N-550 Pulse Oximeter is indicated for the continuous non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. The N-550 Pulse Oximeter is intended for use with neonatal, pediatric, and adult patients during both no motion and motion conditions and for patients who are either well or poorly perfused, in hospitals, hospital-type facilities, intra-hospital transport, and home environments. This device is for prescription use only.

Device Description

The N-550 Pulse Oximeter is designed for continuous, non-invasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate by use of one of a range of compatible Nellcor Puritan Bennett OxiMAX oxygen transducers (sensors). The N-550 Pulse Oximeter displays digital values of SpO2 and Pulse Rate, and individual LED's are used for status indicators. Pulse Amplitude is displayed by means of a "blip bar" presentation.

AI/ML Overview

The provided document is a 510(k) summary for the Nellcor OxiMAX N-550 Pulse Oximeter, asserting its substantial equivalence to a predicate device (Nellcor OxiMAX N-595 Pulse Oximeter). The document does not contain detailed information about specific acceptance criteria or the results of a study designed to prove the device meets those criteria. Instead, it states that clinical and non-clinical tests were performed and concluded that the device does not raise new questions of safety or effectiveness.

Therefore, the following information is not available in the provided text:

A table of acceptance criteria and reported device performance.
Sample size used for the test set and data provenance.
Number and qualifications of experts for ground truth.
Adjudication method for the test set.
Results or even the conduct of a multi-reader multi-case (MRMC) comparative effectiveness study.
Results or even the conduct of a standalone (algorithm only) performance study.
Type of ground truth used.
Sample size for the training set.
How ground truth for the training set was established.

What is available:

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

Summary of Technological Characteristics of the Device Compared to the Legally Marketed (Unmodified) Device

The N-550 Pulse Oximeter has the same technological characteristics as the above referenced predicate device, the N-595 Pulse Oximeter. The only modifications relate to an ergonomic change from LCD to LED display and a change in oximeter module.

Tests Performed to Support Determination of Substantial Equivalence

Clinical and non-clinical tests were performed to support the determination of substantial equivalence. Clinical studies were conducted following regulations under Title 21 of the Code of Federal Regulations (21 CFR), Part 812 - Investigational Device Exemptions, Part 50 - Protection of Human Subjects and Part 56 - Institutional Review Boards.

Conclusions

The technological characteristics of the N-550 Pulse Oximeter and the results of non-clinical and clinical tests do not raise new questions of safety or effectiveness when compared to the legally marketed (unmodified) device.

Dear Ms. To:

This letter corrects our substantially equivalent letter of May 8, 2002 regarding the indications for use of your device. Our letter incorrectly limited your device to use in military environments.

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 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). 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In
