H100b Pulse Oximeter (2020)

by EDAN INSTRUMENTS, INC.

About this oximeter:

The Edan H100B pulse oximeter was tested with its default DB9 adult reusable finger sensor. This device measures oxygen saturation (SpO2), pulse rate (PR), and perfusion index (PI), displaying a waveform along with a pulse bar for visual representation of the pulse signal. The H100B is powered by 4 AA batteries and it includes audible alarms to alert users of critical SpO2 and PR levels.

OpenOx Performance

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, while also trying to account for expanded criteria to improve diversity of skin pigment in study cohorts (US FDA "Approach for Improving the Performance Evaluation of Pulse Oximeter Devices Taking Into Consideration Skin Pigmentation, Race and Ethnicity"). 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 details on how many subjects have been tested as well as details of skin color testing.

Lifetime is assumed to be 10 years. Salvage cost at the end of 10 years is assumed to be zero for all devices. Cost of device maintenance or repair is not assumed to be zero. We assume probe and device replacement intervals based on evolving input from clinician collaborators around the world based on device type alone (i.e. fingertip, handheld, etc.), though note these vary widely by setting and manufacturer. These intervals attempt to grossly account for wear and tear, damage or misplacement and theft.

Independent Arms Study Cohort Size

Currently, there is lack of consensus on optimal study cohort sizes for pulse oximeter validation studies. The 2017 ISO 80601 and 2013 FDA regulatory frameworks stipulate at least 10 subjects, 15% of whom should be darkly pigmented.

We report device results as preliminary once at least 10 subjects have been tested, though continue testing devices in as many diverse participants as we can. We are awaiting updated regulatory guidance for optimal cohort sizes.

% of study cohort with dark skin pigmentation

Currently, there is lack of consensus on optimal methods for characterizing skin pigment and optimal sample sizes for validation study cohorts. 2017 ISO and 2013 FDA documents stipulate at least 10 subjects, 15% of whom should be darkly pigmented. Here we define ‘dark skin pigmentation’ as Monk Skin Tone Scale HIJ and Individual Typology Angle <-30. For the purpose of data analysis and to avoid operator bias from assigning MST, we use ITA >30 for light, ITA 30 to -30 for medium, ITA < -30 for dark, and ITA < -50 for very dark.

Date independent Arms data collected

This is the most recent date that the Open Oximetry Project collected data in the UCSF Hypoxia Lab to assess this device's performance. If ARMS data were obtained from a source other than the Hypoxia Lab, please review the date for that source.

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 'failed' depending on study findings.

% of dark cohort with very dark skin pigment

All devices were tested in participants with light, medium and dark skin pigment as defined by Individual Typology Angle. The value reported here indicates the percentage of individuals from the 'dark' pigment cohort (i.e. ITA < -30) who also had Individual Typology Angle <-50 (i.e. 'very dark' pigment).

Skin pigment bias for SpO2 70-85%

This number (i.e. 'differential bias’ or 'disparate bias') describes how much pulse oximeter performance is impacted by skin pigment. This is done by using real data to model what happens if we compare how accurate SpO2 is (i.e. how SpO2 compares to gold standard blood SaO2 co-oximetry) for a healthy volunteer with very light skin pigment and SpO2 accuracy for a healthy volunteer with very dark skin pigment (i.e., an ITA difference of 100), by subtracting the difference. Read more about differential bias here in our FAQ.

Skin pigment bias for SpO2 85-100%

This number (i.e. 'differential bias’ or 'disparate bias') describes how much pulse oximeter performance is impacted by skin pigment. This is done by using real data to model what happens if we compare how accurate SpO2 is (i.e. how SpO2 compares to gold standard blood SaO2 co-oximetry) for a healthy volunteer with very light skin pigment and SpO2 accuracy for a healthy volunteer with very dark skin pigment (i.e., an ITA difference of 100), by subtracting the difference. Read more about differential bias here in our FAQ.

0.37%

Bias by skin pigment

This number attempts to describe how much oximeter performance is impacted by skin pigment at low oxygen saturations. Differential bias is calculated to assess the variation in SpO2 bias across ITA and MST levels, where the SpO2 bias is the mean of the difference between SpO2 measured by the pulse oximeter and SaO2 measured in the blood by gold standard co-oximetry. Here, the differential bias is calculated as the maximum difference in mean SpO2 bias across ITA and MST levels in saturation range 70-85% and 85-100%.

Bias in dark skin pigment (SpO2 70-84)

This shows the average difference between the oxygen levels measured by the pulse oximeter (SpO2) and the actual blood oxygen levels (SaO2) for participants with dark skin pigment when their oxygen levels are between 70-84%. Negative values indicate the pulse oximeter SpO2 underestimates actual blood oxygen SaO2. Positive values indicate pulse oximeter SpO2 overestimates actual blood oxygen SaO2.

Bias in medium skin pigment (SpO2 70-84)

This shows the average difference between the oxygen levels measured by the pulse oximeter (SpO2) and the actual blood oxygen levels (SaO2) on average for participants with medium skin pigment when their oxygen levels are between 70-84%. Negative values indicate the pulse oximeter SpO2 underestimates actual blood oxygen SaO2. Positive values indicate pulse oximeter SpO2 overestimates actual blood oxygen SaO2.

Bias in light skin pigment (SpO2 70-84)

This shows the average difference between the oxygen levels measured by the pulse oximeter (SpO2) and the actual blood oxygen levels (SaO2) on average for participants with light skin pigment when their oxygen levels are between 70-84%. Negative values indicate the pulse oximeter SpO2 underestimates actual blood oxygen SaO2. Positive values indicate pulse oximeter SpO2 overestimates actual blood oxygen SaO2.

% of cohort with low pulsatility amplitude

We measured percent modulation of infrared red (IR) signal, sometimes also referred to as pulsatility amplitude or perfusion index. This is sometimes used as an imperfect and indirect surrogate for perfusion and signal strength. Here we show the percentage of the cohort tested with this device who had low pulsatility amplitude based on values reported by one of our reference devices, the Nellcor PM1000N. We take the pulsatility amplitude from the PM1000N and divide by 10 for greater consistency with our other reference devices. Of note, this correction factor makes the number from the PM1000N comparable but not the same as PI reported by Masimo devices, for example.
