About this oximeter:
This device was first tested for OpenOximetry by Clinimark Labs in 2020 and is being tested further at present.
YESSignal quality indicator
Root mean square error (Arms) is a common measure of pulse oximeter device performance that combines bias and precision. Here we report Arms based on Open Oximetry device testing using 2013 FDA Guidelines for 510k submissions and 2017 ISO 80601. Read more about quantification of oximeter performance on our FAQ.
*NOTE: performance is only reported here once we have tested the device in >10 study subjects (i.e. as required by 2013 FDA and 2017 ISO requirements). Performance may change significantly as we continue to perform testing in additional subjects and conditions. Please continue to check back as we update frequently. Click the device to see how details on how many subjects have been tested as well as details of skin color testing.
Here we report retail purchase costs (US $) for buying the pulse oximeter, including one adult finger probe. Costs are obtained from one or multiple sources including manufacturers or online retail stores. Of note, some devices have special discount pricing for low and middle-income countries. The special prices are not accounted for in this report.

Estimated Lifetime Cost:
Adjust the assumptions below to estimate the 10-year lifetime cost for this device:
Time to processor replacement
Monthly power cost (e.g batteries)
Some oximeters may be rebranded, relabeled and sold by multiple distributors under different names. We are attempting to compile 'aliases' for devices.
Distributed by Gurin Products
We categorize devices as fingertip, handheld, benchtop, multimodal, phone-based or wearable.
Reflectance or Transmittance
Some devices may have capability to function as transmission and reflectance modes using different probe types. Read more about the difference between reflectance and transmittance devices in our FAQ.
This indicates the location where the device is manufactured as stated by the manufacturer (or the stated location of the manufacturer). Please note, devices may contain components manufactured in different location.
Ingress Protection (IP)
Here we try to report device features such as signal quality indicator, waveform, carboxy-Hb, perfusion index and ability to measure Hb.

Standard Performance info
Producer claimed Arms (root mean square error) for SpO2 70-100%
Independent Arms (root mean square error) for SpO2 70-100%
Data independent Arms data collected
This is the date that the Open Oximetry collected data in the UCSF Hypoxia Lab data to 'verify' or 'dispute' device performance. If Arms data were obtained from a source other than the Hypoxia Lab, please review the date for that source. Of note, device performance may be specific to a model year (even if the model name has not changed).
Source of independent Arms data
Root mean square error (Arms) is a common measure of pulse oximeter device performance. 'Arms' may be ascertained from manufacturers' published data, 510k reports, package inserts or primary data from testing conducted by the UCSF Hypoxia Lab. Devices independently tested by the Open Oximetry Project will be marked 'verified' or 'disputed' depending on study findings.

Here are select manuscripts published in the peer-reviewed literature.
Data published by manufacturer
We are working to gather device performance data published directly by manufacturers.
Low perfusion performance data
We are working to gather data on device performance during varying conditions such as low perfusion. We are also working to standardize protocols for such testing. Read more on 'perfusion' in our FAQ.
Raw PPG data
We are working to gather raw data for device performance to share for independent analysis. We expect to launch this feature later in 2023.
In vitro (simulator) performance data
We are working on novel in vitro testing protocols for both commercially available devices (e.g. Fluke ProSim8) and novel in vitro devices. We expect to report data for this testing later in 2023.
