## Indications for Use

SpO2 Sensors are indicated for continuous, non-invasive functional arterial oxygen saturation and pulse rate monitoring.

## Device Story

SpO2 sensors are electro-optical accessories for pulse oximeters; non-invasive; no skin penetration or electrical contact. Device utilizes two LEDs (660/895 nm or 660/940 nm) as light sources and one photodiode as a detector to measure light absorption of functional arterial hemoglobin in the finger. Sensor housed in a soft pad with a clear window; connects via cable to a monitor. Used in clinical settings for continuous monitoring of oxygen saturation and pulse rate. Output is processed by the connected oximeter to provide real-time physiological data to clinicians, facilitating patient monitoring and clinical decision-making.

## Clinical Evidence

Clinical hypoxia studies conducted in an independent research lab compared subject sensors to arterial blood samples analyzed on a laboratory co-oximeter. Results demonstrated accuracy equivalent to predicate device claims. Bench testing verified pulse rate accuracy. Biocompatibility, electrical safety, and EMC testing performed to demonstrate conformance with industry standards.

## Technological Characteristics

Electro-optical sensor; two LEDs (660/895 nm or 660/940 nm); photodiode (3 mm2 or 8 mm2 active area); multi-conductor shielded cable with PVC jacket; finger clip form factor; non-sterile; reusable; connects to pulse oximeter monitor.

## Regulatory Identification

An oximeter is a device used to transmit radiation at a known wavelength(s) through blood and to measure the blood oxygen saturation based on the amount of reflected or scattered radiation. It may be used alone or in conjunction with a fiberoptic oximeter catheter.

Date Prepared November 1, 2005

Product Name SpO2 Sensor (accessory to pulse oximeter)

Predicate Device K973970, K002223

### Product Description

SpO2 sensors are electro-optical sensors that function without skin penetration, electrical contact, or heat transfer. The sensor uses optical means to determine the light absorption of functional arterial hemoglobin by being connected between the patient and the oximeter. The sensor contains three optical components: two light emitting diodes (LED) that serve as light sources and one photodiode that acts as a light detector. The optical components are housed in soft pad with a clear window. The sensor cable is terminated in a connector that couples with the corresponding monitor.

Intended Use

SpO2 Sensors are indicated for continuous, non-invasive functional arterial oxygen saturation and pulse rate monitoring.

Dear Mr. Caso:

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.

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