Successful Measurement

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.

• 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.

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 power cable into the device. The DC port does not charge the batteries or device. This 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.

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 reading will be transmitted when your BPM finds a cellular network to connect to.

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.

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

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.

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

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

The Tenovi Cellular BPM 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, if two or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±25% of the average; or if four or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±15% of the average value, the irregular pulse symbol will be displayed along with measurement results.

5. Error messages (refer to Error Codes section).

6. Measurement reminder icon

7. Triple Measurement icon. The number inside the arrows indicates which measurement is currently in progress.

8. Cuff wearing detection icon. If the word “OK” does NOT appear inside the symbol, that means there is a cuff error (refer to Error Codes section).

9. Cuff abnormal icon. This means the air connector is not inserted properly into the device (refer to Error Codes section).

10. Excessive body motion detector icon. This appears when too much movement was detected during a measurement causing the device to turn off (refer to Error Codes section).

11. SIM card error icon (refer to Error Codes section).

12. Data pending to transmit icon. This means there are measurements saved on the device that have not been transmitted (refer to Error Codes section).

13. Signal indication icon. This means there is no nearby cellular coverage or there is a cellular connection error (refer to Error Codes section).

14. Adapter Insert Indicator. This means there is power being supplied from an adapter. Please unplug right away as we only authorize use of AA batteries to power your Cellular BPM.

15. Battery Indicator. Shows current battery level.

The Tenovi Cellular BPM will connect automatically out of the box to the nearest cellular network after a successful measurement is completed and transmit your measurements.

The Tenovi Cellular BPM will store historical measurements on the device. This means if your device is unable to find a cellular signal, the BPM will save your measurements. After each measurement the device will attempt to connect to a nearby cellular network and when successful, will transmit all saved measurements. You are not able to cycle through previous measurements on the device itself.

In order to get the best performance, please follow the instructions below.

Cleaning Process:

• Step 1: Before cleaning the monitor, make sure that the monitor is
  switched off and disconnected from the power line.
• Step 2: Clean the cuff with a soft cloth dampened with the soapy water.
  Until no visible contaminants remain.
• Step 3: Rinse the cuff and wipe off the cleaning solution with a fresh cloth
  or towel, dampened with tap water after cleaning until no visible
  cleaning agent remains.
• Step 4: Wipe off with a dry cloth to remove residual moisture.
• Step 5: Air dry the cuff thoroughly after cleaning.

Disinfection Process (Clean the monitor before disinfection):

• Step 1: Before disinfecting the monitor, make sure that the monitor is
  switched off and disconnected from the power line.
• Step 2: Disinfect the cuff with a soft cloth dampened with the 70%
  isopropanol during 10 minutes.
• Step 3: Rinse the cuff and wipe off the disinfection solution with a fresh
  cloth or towel, dampened with tap water after disinfecting until no
  visible disinfection agent remains.
• Step 4: Wipe off with a dry cloth to remove residual moisture.
• Step 5: Air dry the cuff thoroughly after disinfecting.
