How It Works

Top Tips for Successful Measurement

BPM Power

Do not turn off the monitor after measurement is displayed. The device will turn off on it’s own.

Cuff Size

Ensure the cuff size is appropriate for the patient.

Cuff Hose

Ensure the cuff connector/hose end-piece is inserted firmly into the monitor all the way.

Setup & Use Steps

Power Gateway

Step 1: Set up your gateway by plugging it in. It will flash purple as it connects and then settle to a solid red color when it is connected.

Pull Battery Tab

Step 2. BPMs arrive with batteries pre-installed, but there is a plastic guard in the battery door that will need to be removed. Simply pull the tab and the batteries will provide power.

Put on Cuff

Step 3. Position the cuff on your upper left arm (above your elbow) directly on your skin.

Wrap the velcro of the cuff carefully so the edges of the cuff line up with one another (there should be minimal overhang).

Tighten the cuff until you can fit just one finger in-between the cuff and your arm. It is important the cuff is tightly secured so that it inflates properly.

The hose should come out the bottom of the cuff by your elbow joint. Rest your left arm on a table in front of you, palm facing upwards.

When Taking a Measurement

Before You Measure

Blood pressure naturally goes up and down throughout the day. Changes of up to 20 mmHg are completely normal. Things like stress, caffeine, movement, talking, and even a full bladder can cause a higher reading. That’s why it’s important to follow a few simple steps to get the most accurate results.

  • Sit upright in a chair with your back supported
  • Keep your feet flat and legs uncrossed.
  • Rest your arm on a flat surface at heart level.
  • Put the cuff on bare skin, tube facing down, and not over clothing.
  • Stay silent and still. Avoid distractions and moving around.

Taking Your Blood Pressure

  • Measure at the same time each day if tracking over time.
  • Take two readings, one minute apart, and record both.
  • Average the two readings if they are different.
  • Share your readings with our health care provider.

If one reading seems unusually high or low, wait a few minutes, relax, and try again. Blood pressure should be assessed based on patterns and averages over time, not a single measurement.² If you believe your measurement is high, immediately contact your healthcare provider.

Best Practices

Power Supply for Your BPM

Tenovi blood pressure monitors (BPMs) are specifically designed to operate using standard AA batteries. Please note the following important guidelines:

  • Do not attempt to charge or plug in a USB-C cable into the device. The USB-C port does not charge the batteries or device. The USB-C port is only for internal Tenovi debugging purposes.

If a patient is unable to obtain replacement batteries independently, they are available for direct shipment as a supply order.

Cuff Tips

  1. These cuffs are designed to work best on your LEFT arm with bare skin, not over clothing.
  2. Wrap the cuff tightly so that only 1 finger can slide in between the cuff and skin.
  3. Align it properly. To ensure proper placement, we recommend lightly holding the hose in between your pinky and ring finger and having the hose follow the inside of your arm. This will make sure the sensor is in the correct place.
  4. The cuff will inflate and you should see your reading when it is finished. Your Gateway will beep and turn green.

Choosing the BPM Cuff Size

Accurate blood pressure measurement is critically dependent on the use of an appropriately sized cuff. This section outlines the recommended procedures for selecting the correct cuff.

Gold Standard: Arm Circumference Measurement

For optimal accuracy, the gold standard method for determining cuff size involves directly measuring the patient’s arm circumference.

Procedure: Using a flexible measuring tape (or a string and ruler), measure the circumference of the patient’s upper arm. The measurement should be taken over the lower bicep, at the midpoint between the shoulder and the elbow.

 

 

 

 

 

 

 

Cuff Selection: Once the arm circumference is obtained, select a blood pressure cuff where the patient’s arm circumference falls within the middle range of the cuff’s indicated circumference.

Avoid selecting a cuff where the measurement is at either the very minimum or maximum edge of the cuff’s specified range, as this can compromise measurement accuracy. Optimal fit ensures the inflatable bladder properly encircles the brachial artery.

Extra Small (XS) = 15-28cm

Wide Range (WR) = 22-42cm

Extra Large (XL) = 32-52cm

Alternative Method: BMI Estimation

In situations where direct arm circumference measurement is not an option, Body Mass Index (BMI) can serve as a reasonable estimation tool for initial cuff selection.

Application: Utilize the patient’s BMI to make an educated guess regarding the appropriate cuff size. To assist with this, refer to the BMI chart below, which also provides suggested cuff categories based on your custom ranges.

Important Consideration Regarding BMI Accuracy: It is crucial to acknowledge that BMI is calculated solely based on height and weight and does not account for body composition (i.e., the proportions of bone, muscle, and fat). These tissue types have significantly different densities. Consequently, individuals with the same BMI may have vastly different arm circumferences due to variations in muscle mass or bone structure, potentially leading to an inaccurate cuff fit and compromised blood pressure readings. Wherever possible, direct arm circumference measurement should be prioritized.

Body Mass Index (BMI) and Suggested Cuff Categories

Use this chart to find the approximate BMI based on height and weight. The colored cells and corresponding labels indicate a suggested cuff category based on the following BMI ranges:

  • Small: BMI < 25
  • Large: 30 BMI < 40
  • XL: BMI ≥ 40
  • (S) indicates a BMI < 25, suggesting a ‘Small’ cuff category.
  • (L) indicates a BMI ≥ 30 and < 40, suggesting a ‘Large’ cuff category.
  • (XL) indicates a BMI ≥ 40, suggesting an ‘XL’ cuff category.

Note: The ranges provided for Small, Large, and XL are custom to your request and do not align with standard clinical BMI categories (Underweight, Normal, Overweight, Obese Class I/II/III). This chart is intended solely as an estimation tool for cuff sizing based on these custom categories.

Please take measurement again while staying quiet and don't move.

Er 7

The pressure that the sensor sensing is over the limit

Please attempt to take another measurement. If the error occurs again, please contact Customer Support.

Device Appears Frozen/Unresponsive

If the device screen looks frozen, unresponsive, or stays on for more than 5 minutes take the batteries out and put them back in.

There is not a way to reset or recalibrate the BPM. Taking the batteries out will ensure the device is off. This will not erase saved measurements.

BPM May Display “HI” or “LO”

This is not an error but means measurement is too low or too high for the device to measure. The Tenovi BPM can only measure accurately in the following ranges:

  • Systolic: 60mmHg to 260mmHg
  • Diastolic: 40mmHg to 220mmHg
  • Pulse: 40-199 beats/minute

For more information on the variability of blood pressure measurements, see our dedicated reference for BPM Variability.

BPM not transmitting to Gateway, no error code displayed

  1. Confirm that your Tenovi Gateway is plugged in and has a RED or GREEN light.
  2. Retake your measurement while keeping the BPM as close to the Gateway as possible.
  3. If your BPM still is not transmitting after a successful measurement, please contact Customer Support.

Device Specifics

Device Buttons

Mute: Turn the voice operator on/off.

Scroll Buttons: Cycle through your overall average measurement and past measurements.

3 MEAS: Takes 3 back to back measurements and will display your current average blood pressure.

Start/Stop: Begin or end a single BP measurement.

Irregular Heartbeat Event

The Tenovi BPM Gen 3 can also identify an Irregular Heartbeat (IHB). An IHB is flagged when the device detects a significant variation in the heart’s rhythm (the time between successive beats) during a measurement. Specifically, an irregular heartbeat is detected when a pulse interval is either 25% slower or 25% faster than the average rhythm calculated for that measurement. This icon will appear at the end of your measurement if an irregular heartbeat is detected:

Pairing and Bonding

The Tenovi Blood Pressure Monitor will connect automatically out of the box to your Tenovi Gateway during the measurement. There is no pairing needed for the BPM to connect to your Tenovi Gateway.

Storage Events

The Tenovi Blood Pressure Monitor can store up to 200 historical measurements. This means if you’re on vacation and not near the Gateway, the Tenovi Blood Pressure Monitor will save up to 200 measurements. If you take more than 200 readings while still away from the Gateway, the first measurement you took will be erased as you take new measurements. You are able to cycle through previous measurements on the device itself by pressing the Scroll Buttons.

Maintenance

Clean both the device and cuff with a soft, dry cloth. If necessary use a dampened cloth and natural detergent. Do not use alcohol, benzene, or other harsh chemicals.

Store the device, cuff and adapter in a clean, dry place, and protect it against extreme moisture, heat, lint, dust and direct sunlight.

Device Reissue

If this is a replacement device please visit the Tenovi Web App for further assistance.

The Tenovi Blood Pressure Monitor is compatible with Gateway firmware 1.8 and later. Using a Gateway with an earlier firmware version may cause connectivity problems.

Gateway Basics

Getting Started

This means that the Gateway is trying to connect to a cell tower. Once connected to a cellular network, the Gateway will turn RED. If it goes RED and back to PURPLE , it’s looking for the strongest signal. The Gateway will go from PURPLE to BLUE if it can’t find a signal.
