Intended Use
The Nonin Medical 3250 Finger Pulse Oximeter is a small, portable device indicated for use in measuring and displaying functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate of individuals who are well or poorly perfused under no motion conditions for medical use without a prescription. It is intended for spot-checking of individuals 18 years and older with finger thickness between 0.8-2.5 cm (0.3-1.0 inch). It is not intended for the diagnosis or screening of lung disease, for use in treatment decisions, and should only be used for making heathcare decisions under the advice of a healthcare provider.
Device Description
Model 3250 Pulse Oximeter is a small, lightweight, portable, battery operated, digit pulse oximeter that displays numerical values for functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate and is intended for over-the-counter use. The device measures the absorption caused by the pulsation of blood in the vascular bed, which are used to determine oxygen saturation and pulse rate. Light emitting diodes (LEDs) are contained within the device along with the photo detector, which is on the opposite side of the probe from the LEDs. The SpO2 and pulse rate are displayed on the LCD display of the device. The LCD also provides a visual indication of the pulse signal, while blinking at the corresponding pulse rate. The display will indicate poor pulse quality that may affect the readings. All associated electronics and the microcontrollers are within the sensor, which is activated by inserting a patient's digit. This simple operation activates the internal circuitry automatically upon application. The Model 3250 includes a Bluetooth radio to send real time oximeter readings to a host device. The Model 3250 features a Bluetooth LE version 4.0 radio to ease the connectivity setup configuration with options to implement secure connections for the point-to-point data connection. This oximeter uses ISP3, Nonin's core signal processing technology software.

No
The description focuses on traditional pulse oximetry technology using LEDs, photodetectors, and signal processing (ISP3). There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies.

No.
The device is used for measuring and displaying oxygen saturation and pulse rate, which is a diagnostic function, not a therapeutic one. The description explicitly states it is "not intended for the diagnosis or screening of lung disease, for use in treatment decisions."

No

The "Intended Use" section explicitly states, "It is not intended for the diagnosis or screening of lung disease, for use in treatment decisions, and should only be used for making healthcare decisions under the advice of a healthcare provider." This indicates that while it measures physiological parameters, its output is not for direct diagnostic purposes.

No

The device description explicitly states it is a "small, lightweight, portable, battery operated, digit pulse oximeter" and mentions hardware components like "Light emitting diodes (LEDs)", "photo detector", "LCD display", and "internal circuitry". While it includes software ("ISP3, Nonin's core signal processing technology software") and Bluetooth connectivity, it is fundamentally a hardware device with integrated software.

Based on the provided text, the Nonin Medical 3250 Finger Pulse Oximeter is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Nonin 3250 measures functional oxygen saturation and pulse rate by shining light through a finger and detecting the absorption. This is a non-invasive measurement performed on the body, not on a sample taken from the body.
  • Intended Use: The intended use clearly states it's for measuring and displaying %SpO2 and pulse rate of individuals. It does not mention analyzing biological samples.

Therefore, the Nonin Medical 3250 Finger Pulse Oximeter is a non-invasive medical device used for physiological monitoring, not an In Vitro Diagnostic device.

Summary of Performance Studies

Nonin's Model 3250 Oximeter is supported by both laboratory and clinical hypoxia accuracy testing in order to ensure that it has appropriate performance, functional features to fully comply with ISO 80601-2-61:2017, and IEC 60601-1-11 collateral standard for home healthcare equipment.

The clinical performance testing included data from an independent study by Leeb and an internal study conducted at UCSF using Nonin's Model 9590. The optical path and algorithm for the Model 3250 is equivalent to the Model 9590.

Leeb study:
Sample size: 34 participants with diverse skin pigmentation.
Protocol: Controlled desaturation study with arterial oxygen saturation (SaO2) plateaus between 70% and 100%. Skin pigmentation was assessed subjectively using a perceived Fitzpatrick Scale (pFP) and objectively using the individual typology angle (ITA) via spectrophotometry at nine anatomical sites.
Key results (ARMS between %SaO2 70-100%): Light skin: 1.8; Medium skin: 1.7; Dark skin: 2.3. Overall ARMS: 2. Bias (between %SaO2 70-100%): 0.6.

UCSF study:
Sample size: 26 participants with diverse skin pigmentation.
Protocol: Controlled desaturation study with arterial oxygen saturation (SaO2) plateaus between 70% and 100%. Skin pigmentation was assessed subjectively using both Fitzpatrick Scale and Monk Scale, and objectively using the individual typology angle (ITA) via spectrophotometry using five anatomical sites.
Key results (ARMS for 70-100% SaO2): 2.27.
Bias (between %SaO2 70-85%): Light skin: 1.9; Medium skin: 1.14; Dark skin: 2.57.
Bias (between %SaO2 85-100%): Light skin: 0.98; Medium skin: 0.43; Dark skin: 1.08.

Overall conclusion: The result of the clinical testing supports the performance of the subject device, Model 3250, across all skin pigmentation. The subject device demonstrated equitable performance for the intended user population across all skin pigmentation sub-groups and the accuracy was within 3.0% ARMS quidance, without any clinically significant bias compared to the blood reference SaO2, or between the groups.

Clinical Data:

Performance clinical testing for pulse oximeter accuracy and usability testing participation by users is identical to the predicate device in 510(k) K131021.

To support the performance of the Model 3250, clinical data is provided as part of this submission.

The clinical performance testing included data from an independent study by Leeb and an internal study conducted at UCSF using Nonin's Model 9590. The optical path and algorithm for the Model 3250 is equivalent to the Model 9590. Therefore, the data from these two studies can be used to substantiate the Model 3250. The results support similar performance across all skin pigmentation.

In the Leeb study, there were 34 participants with diverse skin pigmentation utilizing a controlled desaturation study with arterial oxygen saturation (SaO2) plateaus between 70% and 100%. Skin pigmentation was assessed subjectively using a perceived Fitzpatrick Scale (pFP) and objectively using the individual typology angle (ITA) via spectrophotometry at nine anatomical sites.

In the UCSF study, there were 26 participants with diverse skin pigmentation utilizing a controlled desaturation study with arterial oxygen saturation (SaO2) plateaus between 70% and 100%.

The result of the clinical testing supports the performance of the subject device, Model 3250, across all skin pigmentation. The subject device demonstrated equitable performance for the intended user population across all skin pigmentation sub-groups and the accuracy was within 3.0% ARMS quidance, without any clinically significant bias compared to the blood reference SaO2, or between the groups.

Usability of the reference device Model 3230 is used to substantiate usability of the Model 3250 OTC. Self-selection of an OTC device is substantiated by similar indications for use to the predicate device MightySat OTC. To further support OTC use, updates were included in the 3250 OTC IFU.

Conclusion: Nonin's Model 3250 is substantially equivalent to Masimo MightySat under K214115 supports the OTC indication of the 3250 and does not raise new questions of safety and effectiveness. In addition, the reference device Nonin's Model 3230 finger pulse oximeter cleared by the FDA under K131021 on 9/11/2013, supports the indications for use and labeling for Model 3250.
