Ember is intended for use by athletes or their trainers to help measure and track hemoglo-
bin, pulse rate, perfusion index, oxygen saturation, oxygen content, respiration rate or
pleth varability index. It is intended to be used by individuals 13 years or older with a
finger width of 22mm or less. This product is not a medical device.*
The Ember system consists of the device, sensor, and mobile app. The Ember device
requires a smartphone with Bluetooth 4.0 capabilities to operate, running iOS 8.2 or
newer. For a list of devices and operating systems that the Ember system works with, please
visit www.cercacor.com.
*This product is not intended to monitor or alleviate a physiological condition or disease state. Individuals who need a device to monitor a
medical condition should contact their physician. Ember is not meant to replace laboratory measurements nor is it intended for medical use. If
you want more accurate hemoglobin assessments, please use invasive methods using properly conducted Cyanmethemoglobin assay or
properly conducted and calibrated Coulter Counter testing.

Taking a Measurement
•
•
•
The cable should be on top of your hand
in a straight line as far as possible.
Always use the same finger for every
measurement. Ensure your finger is all
the way into the sensor.
Use the same posture and remain still
during measurement.
Begin by placing the sensor on a finger free of deformities. It is best to use the ring or
middle finger of your non-dominant hand. It is recommended to not use nail polish for best
accuracy and repeatability of measurements. Blue or green nail polish significantly affect
the accuracy of the measurement.

Once you are ready, tap the “Start” button within the app. The measurement time
varies and can be as fast as 30 seconds. Be patient, the system will ask you to try again
if it cannot get a result within 90 seconds.
Your measurement results will be displayed on the screen. When you tap the
“Capture” button, the numbers displayed will be saved in your history. The gauge to the
right of the display tells you your target range based on your age and biological sex
(must have an account for gauges to be enabled). You can customize the target range
based on your individual goals by accessing the “Options” tab of the app.
Be sure not to move around during the measurement.
Refrain from talking, coughing, or sneezing during the measurement.
During the measurement, a question related to the activity will be displayed.
Please be sure to answer this question to get more value from your graphs.

Your Ember device is capable of measuring numerous parameters depending on your
model or the number of parameter upgrades that you have installed.
Hemoglobin (Hgb)
The protein contained in red blood cells that is responsible for delivery of oxygen to
the tissues. The range of hemoglobin values can vary based on your age and biologi-
cal sex. For adults 18 years and over at rest, hemoglobin values can be between
12-15.5 g/dl for females and 13-17.2 g/dl for males. Tracking your Hgb first of day
and Pre/Post specific activities such as workouts or hydration may help you under-
stand the intensity of your workouts and the fluid volume shifts and/or recovery times.
Additionally, you may be able to learn the extent to which elevation training increases
your Hgb and how long the effect lasts after returning to sea level.
Parameter Descriptions
Pulse Rate (Pr)
1
11
Perfusion Index (PI)
The strength of blood flow/circulation at your finger tip measured as a percentage
(%). Values for PI range from 1-20%. When selecting your measurement finger for the
first time, it is good to use the ring or middle finger with a higher PI value.
19
The number of beats your heart takes per minute (bpm) as detected from the pulsation
at your finger tip. At rest values range between 50-85 bpm however fit individuals
typically have lower resting heart rates. This is because their heart is more efficient and
effective with each beat that it requires fewer beats per every minute. Tracking your
pulse rate first of day and pre and post work out is a great benefit of using Ember to
get an understanding of the intensity of your workouts as well as the impact over time
to your fitness level on your first of day pulse rate.
Oxygen Content (OC)
1
11
The amount of hemoglobin that is saturated with oxygen expressed as a percentage
(%). At rest you should be greater than 95% oxygen saturated and after an intense
workout you may go less than 85%. The lower your SpO the less effective your
muscles and tissues are for performance. Tracking your SpO with specific activities
throughout the day with Ember may help you understand the quality of your oxygen
exchange.
20
The total amount of oxygen bound to hemoglobin. This value is derived from your
hemoglobin and oxygen saturation levels in millilitres per decilitre of oxygen (ml/dl).
At rest values can range between 15.2 - 23 ml/dl. By tracking this number with Ember,
you may discover that you have better endurance and performance when your OC is
trending higher.
