Recommended use of ambulatory blood pressure monitoring

The European Society of Hypertension has published recommendations for ambulatory blood pressure measurement (O’Brien, E. et al. on Behalf of the European Society of Hypertension Working Group on Blood Pressure Monitoring, European Society of Hypertension recommendations for conventional, ambulatory and home blood pressure measurement, Journal of Hypertension 2003, 21: 821-848). Ambulatory blood pressure monitoring can bene t patients with in many situations.

Indications

• Suspected white-coat hypertension

• Suspected nocturnal hypertension

• To establish dipper status

• Resistant hypertension

• Elderly patient

• As a guide to antihypertensive drug treatment

• Type 1 diabetes

• Hypertension of pregnancy

• Evaluation of hypotension

• Autonomic failure

On the contrary, ambulatory blood pressure monitoring should be avoided in several situations.

Contraindications

• Non-cooperative patients, unconscious or otherwise incapable patients

• Patients requiring urgent / emergency cardiac care

• Patients with coagulation disturbances

• Patients with serious mobility or other impairments without supervision

• Children without supervision; children younger than 8 years

• Though the blood pressure measurement algorithm used in the

OMRON M24/7 has been found to function properly on patients with atrial  brillation or other common arrhythmias, the oscillometric blood pressure measurement method is generally recommended for use only with special caution in patients with arrhythmias, Parkinson’s disease, or other diseases with tremors.

2. Operating Instructions

2.1. Working with the OMRON M24/7 Unit

The OMRON M24/7 device is a compact, lightweight monitoring unit typically worn by the patient for 24 hours. The OMRON M24/7 operates with two AA size batteries. The memory is capable of storing more than 600 measurements. Stepwise pressure de ation ensures quality measurements, even if disturbing environmental factors occur. You may  nd the battery compartment and the rating label on the backside housing. The serial number is placed on the rating label, however it is also stored electronically in the solid state memory of the device. On the front side of the housing, there is the LCD, the buttons of the device and the name of the device. The device can be connected to the USB port of a PC with an optoelectronic interface. The device has its socket positioned on the opposite side from the cuff connector. Patients can start extra blood pressure readings or mark symptomatic events.

2.2. Using the Buttons

On the front side of the housing, below the LCD, you may  nd three buttons: the START button is marked with a triangle, the EVENT button marked by a heart and the DAY/NIGHT button indicated by a crescent moon. If the device is turned on, then every button press is accompanied by a short beeping sound.

START button

EVENT button

DAY/NIGHT button

Cancel a blood pressure measurement

The patient can interrupt a blood pressure measurement by pressing a button at any time while the cuff is in ated. This will result in immediate fast cuff de ation. Such interruption is limited to the measurement in progress only and has no effect on further operation. This function is available with all three buttons. Use this function only if the cuff is hurting the patient’s arm.

Manual blood pressure measurement

If it seems necessary, the patient can start an additional, manual blood pressure measurement by pressing the START button for less than 3 seconds. The result with a manual measurement marker will be stored in the memory of the device. Typical causes for this use: dizziness, palpitations (angina pectoris or headache).

Switching the device off

Press and hold the START button for more than 10 seconds then release it when two horizontal segments appear on the LCD, this way the OMRON M24/7 will be switched off. If you do not release the button in 2 seconds after the two horizontal segments appeared, the monitor will return to normal operation. This feature helps to avoid unintended power-off. The device can only be switched on manually.

While the monitor is switched off normal functions are not available, even prescheduled measurements will not be triggered. Therefore, only in case of a valid reason should the device be switched off.

Switching the device on

The OMRON M24/7 is switched on to normal operation if the START button is pressed and held for more than 3 seconds. If the device is switched off, no other functions are available.

LCD check

Press and hold the START button 3 to 5 seconds to light up all segments of the LCD to check if they all work correctly.



Battery voltage check

Press and hold the START button for more than 5 seconds to display battery voltage on the LCD (e.g. 2_37, equal to 2.37 V, see example). After checking the voltage, please release the button, because after additional 5 seconds, the device may turn off. The unit will then return to displaying time. The voltage for fresh alkaline batteries should be over 3 V and for fully charged accumulators over 2.5 V.



Set a patient event marker

The patient can mark any event without starting a manual blood pressure measurement by pressing the EVENT button brie y. A typical causes for this use is taking medicine. The patient should be instructed to record the reason for setting an event marker in a diary (see Patient’s Quick Guide and template for patient diary at the end of this user manual).

Mark time of going to bed and rising from bed

If the DAY/NIGHT shift function is disabled during programming, the patient can press the DAY/NIGHT button to mark the time of going to bed (in the evening) and rising from bed (in the morning).

Manual DAY/NIGHT shift

If this function is enabled during the programming, then the patient can manually shift the measurement frequency period (day or night) by pressing the DAY/NIGHT button. The shift is available in the two hour period before the prescheduled shift.

2.3. Overview Display

The OMRON M24/7 shows important status information, the processes and results of individual readings on its LCD. The most important displays are listed here. In addition to these, a lot of extraordinary situations and errors have their own code displayed on the LCD. These codes are stored together with recorded data and listed in the OMRON BP Tracker Software. This helps service personnel in case of support issues.

The monitor must be programmed with the OMRON BP Tracker Software installed on the computer (for details see Software Manual). Once the preprogrammed time is reached, the monitor will start operating automatically and perform blood pressure measurements based on the monitoring plan. To obtain reliable BP readings, certain rules must be observed.

2.4. Rules of Monitoring

1. Inform the patient about the goal and expected results of the monitoring.

Provide an event/patient diary and rules to observe. The Patient’s Quick Guide will help the patient to remember what has been discussed with you.

The Patient’s Quick Guide can be given to the patient. It also includes a patient diary. This can be found at the end of this user manual, electronic versions are available on the CD-ROM or DVD.

2. Patients can  t the unit comfortably with the adjustable straps of the carry

pouch.

3. It is advisable to wear a thin shirt under the ABP cuff. This does not in uence

the accuracy of blood pressure measurement, but it prevents problems caused by long-time wear of the cuff (sweat, itching, soreness, etc.).

4. The cuff should be properly placed and connected.

5. Patients should avoid excess movement during blood pressure measurements.

They should hold their arm loose, slightly away from their chest.

6. Should the blood pressure measurements cause blood shots, torpidity or

pain in the hand, the cuff should be removed from the arm immediately and disconnected from the monitor. Such occurrence should be reported to the physician as soon as possible or at the latest after the monitoring session.

7. Patients should not remove the monitor even at night. By loosening the straps,

they can avoid problems when turning in their sleep. The monitor does not disturb most patients at night.

8. Patients may start extra blood pressure measurements with the START

button of the OMRON M24/7 monitor, marked with a triangle. They should mark events such as taking medication with the EVENT button, marked with a heart. They should also mark the time of going to bed and rising from bed, with the DAY/NIGHT button marked with a crescent moon. They may interrupt any single blood pressure measurement if necessary by pressing any button.

9. Should the batteries run down during a monitoring session, they can be simply

replaced. Monitoring will continue, and data will not be lost.

10. Patients should never measure anybody else’s blood pressure with an

OMRON M24/7 during an ambulatory blood pressure monitoring session.

2.5. Monitoring Step by Step

Before you begin, you must have the OMRON BP Tracker Software properly installed and con gured on your computer, and the monitor correctly connected (for details see Software Manual). To program your monitor, you will need the optical interface cable which is included in the set properly connected to your computer’s USB port and the communication port (USB) correctly selected in the OMRON BP Tracker Software.

A successful monitoring session consists of the following steps:

1. Connecting the OMRON M24/7 monitor to the PC (First connection only

– not required to repeat with each session)

1. Connect the optical interface, which was delivered with the device, to the USB port of the PC.

2. The other side of the optical USB interface cable, which is a two-point plastic connection, should be connected to the socket of the OMRON M24/7, in a way that the red plastic ring is directed to the lower side of the device.

3. Start the OMRON BP Tracker Software and open the Options menu, then click on the Communication tab on the left side of the screen.

4. On the appearing window, click on the USB option. Please connect the device to the PC (fresh/charged batteries, device switched on) as noted above then click on the Test button. Upon successful communication the software will display the serial number and the  rmware version of the device.

2. Preparation of Monitoring Session

1. Inform your patient about the monitoring rules well in advance.

2. Programming the measurement plan into the device:

• Using PC: start the OMRON BP Tracker Software program

• Optionally the device can be programmed without using a PC, for

details see Manual Programming section.

3. Enter new patient data or select patient from the database.

4. Create a monitoring plan with respect to the patient’s lifestyle.

5. Insert two fresh or fully charged, AA size batteries into the battery compartment and check their voltage.

6. Connect the monitor to the computer.

7. Send the monitoring plan from the computer to the monitor unit.

8. Apply the cuff to the patient with the device placed in the carry pouch.

9. Give the Patient’s Quick Guide to the patient along with detailed instructions about the rules and the usage of the device.

3. Evaluation

1. Remove the unit and cuff from the patient on his/her return.

2. Ask for the Patient’s Quick Guide /patient diary, and ask the patient for any events, symptoms, observations or complaints.

3. Start the OMRON BP Tracker Software

4. Connect the device to the PC and then transfer collected data from the monitor to your database.

5. Analyze the blood pressure pro le.

6. Create and print a report.

2.6. Manual Programming

The OMRON M24/7 can be programmed with using its buttons, without using a PC.

Programming Options

There are three different measurement plans which may be selected in case of manual programming. These plans are stored in the device’s inside memory and they cannot be changed. The  rst plan which is also the default one in the OMRON BP Tracker Software, measurements every 15 minutes during daytime and 30 minutes during night. The second one provides less frequent measurements with 20 and 40 minutes respectively. The third version is based on 30 minute measurement intervals, independent of the time of day. Other settings are the same in case of all three plans: cuff size not set, pressure limit 300 mmHg, enabled LCD display and disabled day/night shift. Daytime starts at 6:00, night time starts at 22:00, special session is disabled. Measurement period is exactly 24 hours.

Measurement Timing

The  rst measurement has a controlling purpose and it starts in the second minute after the programming, then in the next  ve minutes there are no measurements. The rest of the measurements are taken at speci c 15/20/30/40 minute intervals and there are measurements at the 6:00 and 22:00 hour shifts. The last measurement is exactly 24 hours after the second measurement. Patient information can be selected or added later in the OMRON BP Tracker Software.

Manual Programming Step by Step

1. Push the measurement (triangle) and the day/night shift (moon) buttons simultaneously.

2. Keep them pushed, in 10 seconds the measurement options will be displayed for 3 seconds each along with the measurement frequencies. Then the clock will be displayed.

3. In order to choose the measurement plan, you must release the buttons while that plan is displayed. You will hear two beeps and the LCD will display four blinking “o” (oooo for four seconds). The process of programming takes approximately four seconds, then you will hear  ve beeps. For  ve seconds, the chosen plan will be displayed again for con rmation. If programming fails for some reason, the E90 error code will be displayed on the LCD.

In case of manual programming there is no time setting, as the PC would be responsible for time synchronizing. If the time setting is imprecise then the time of measurements may be false. If you would like to use the manual programming function then do not leave the device without batteries for a longer period. If you do so then program the device with the PC once and then leave the batteries in it, so the time can be set by the PC.

Software The OMROM M24/7 programmed manually can be used with the OMRON BP Tracker Software version 1.14.6 or newer.

Manual programming LCD displays:

Normal status: time is displayed

1. measurement plan: 15/30 minute day/night intervals

3. measurement plan: 30/30 minute day/night intervals

10 second delay state: time is displayed but with no double-dot

2. measurement plan: 20/40 minute day/night intervals

Programming in progress: blinking signal

2.7. Batteries

The OMRON M24/7 ambulatory blood pressure monitor operates with two 1.5V AA batteries or two 1.2V AA rechargeable batteries. Use only standard longlife (alkaline) batteries, or standard NiCd or NiMH rechargeable batteries of the proper size. Do not use lithium batteries. Do not mix different battery types, do not mix new and old batteries. Never use batteries of low or unknown quality or preused batteries, as they may not cover the power needs of the monitor, and they may damage the monitor, as they may contain acidic electrolytes which may leak and corrode electronic components. Never use batteries damaged in any way. Should the batteries run down during a monitoring session, they can be replaced. Monitoring will continue and data will not be lost. If you do not use the monitor, it is advisable to remove batteries since they may run down due to the constant small power consumption of the integrated circuits of the device. Data in the monitor are not lost even if batteries run down or are removed. Used batteries may fall under the category of hazardous waste and should be disposed of properly.

Important! It is strongly recommended to use freshly charged accumulators or new batteries with every patient so that batteries do not run down during monitoring, even in case of very high blood pressure values and/or a long monitoring session. After inserting batteries in M24/7monitors, it is advised to check their voltage before programming the monitors. Do not start a new monitoring session with low batteries. The typical voltage for two fully charged rechargeable batteries should be over 2,5 V, and for fresh alkaline batteries, over 3 V. It is possible to check battery voltage with the START button. (Please check the Using the buttons section for more details.)

Important! If a monitor is not used for a long period, the in-built backup cell ensuring the operation of the internal clock may get discharged. In this case keep freshly charged batteries in the monitor for at least one day; this will recharge the backup cell. It is possible to use the monitor afterwards. If the backup cell is not properly charged, the internal clock may work incorrectly, and the monitor may not start measurements in due time.

A set of new, high capacity batteries will enable the OMRON M24/7 monitor to perform 250 blood pressure measurements during a 24-48 hours long monitoring session. If you opt to use alkaline batteries, choose high capacity, long-life products to enable reliable operation. A small crossed battery sign on the LCD shows low battery voltage.

In order to change batteries, take the monitor out of the holder carry pouch and remove the battery compartment cover on the back-side. Place two new, longlife AA alkaline batteries or two properly charged, high capacity AA rechargeable batteries into the compartment as shown in the polarity drawing. Close the compartment.

2.8. Cuffs and their application

The OMRON M24/7 comes with 2 cuffs, normal and large adult size (see below). The bladders are made of neoprene and are latex-free. It is advisable to wear a thin shirt or blouse under the cuff. This does not in uence the accuracy of blood pressure measurements but it prevents possible problems caused by long-time wear (sweating, itching, etc.). Place the cuff on the upper arm so that the

rubber tube points towards the patient’s shoulder and the bladder is placed above the brachial artery, if possible. Contrary to the usual placement with

the tube pointing downwards, the advantage is that the patient can wear a loose jacket over the cuff. Connect the rubber tube of the cuff into the air plug connector, which you can  nd on the long edge closer to the buttons of the OMRON M24/7 monitor. Connect the cuff turning it clockwise with slight pressure.

Note:

Note: It is recommended that the cuff be applied as tightly as acceptable for the

patient. A too loose cuff will cause much longer blood pressure measurement times and possibly aborted measurements. With an overly loose cuff, the monitor must pump to tighten the cuff on the arm and then it must reach the pressure necessary for measurement. This causes considerable inconvenience for the patient and results in less data for evaluation. If the patient removes the cuff for a period during the monitoring session, it should be re-applied with appropriate tightness, with help from another person, if necessary. Should blood pressure measurements cause blood shots, torpidity or pain in the hand after an individual measurement, the cuff should be removed from the arm and disconnected from the monitor. Such occurrence should be reported to the physician at once after the monitoring session.

OMRON M24/7 recognizes and functions with three different cuff sizes. Please set the appropriate cuff size to be used during the programming of the device. Attention: inappropriate setting of the cuff size may lead to device malfunctioning, which is inconvenient for the patient and may lead to an unsuccessful measurement.

3.2. Protection, cleaning and washing

OMRON M24/7 ambulatory blood pressure monitors are not specially protected

against spills or ingression of water or other liquids. Do not immerse the monitor in water or any cleaning  uid, and protect it from spills and splashes. Do not

expose it to heavy rain or steam, and do not wear it in a wet environment e.g: shower, bath, or swimming pool. In case of the minor effects of a wet

environment, wipe off water drops with a dry cloth. Keep the monitor in a normal dry room for at least one hour before use if condensation is suspected. In case of ingress of water in the monitor, remove batteries from the unit, and refer the unit to authorized service. Never place a monitor unit in a disinfecting or sterilizing machine! Recommended cleaning method is to wipe the monitor with a disinfectant cleaning tissue, e.g., Henkel Ecolab Incides, or a similar product. Alternatively, wipe with a slightly damp cloth then dry it with an antistatic tissue. Do not expose monitors to extreme heat or radiation, including long exposure to direct strong sunlight.

To wash the cuff please do the following:

1. Remove the bladder.

2. Wash by hand the sleeve with lukewarm water and regular washing liquid suitable for black material. Rinse well.

3. If required, wipe the bladder with a disinfectant cleaning tissue.

4. Allow both bladder and sleeve to air dry.

5. Replace bladder in the sleeve.

This symbol shows that according to regulations OMRON M24/7 should be handled as electronic waste during disposal.

Blood pressure measurements determined with the algorithm of an OMRON M24/7 monitor on adults are equivalent to those obtained by a trained observer using the cuff/stethoscope auscultation method Korotkoff phase V, within the limits prescribed by the American National Standard for Electronic or Automated

;

Sphygmomanometers. The algorithm used in the OMRON M24/7 also ful ls the requirements of the British Hypertension Society Validation Protocol for Automated Blood Pressure Measuring Devices.

4.2. Safety Concerns

Electric shock hazard protection

OMRON M24/7 monitors meet relevant shock hazard protection standards. OMRON M24/7 monitors operate with two 1.5V AA batteries or two 1.2V AA

rechargeable batteries. This excludes all electric shock hazards, even in the unlikely case of multiple device errors. Use only standard long-life (alkaline) batteries, or standard NiCd or NiMH rechargeable batteries of the proper size. Do not use lithium batteries. Do not mix different battery types, do not mix new and old batteries, do not use damaged batteries.

Many personal computers do not meet certain shock hazard protection standards or strict safety regulations applicable to medical devices. Therefore, during the computer-based use of OMRON monitors, keep at least a 2 meter distance between patient and computer. This is the required minimum safety distance. OMRON M24/7 monitors communicate using a plastic optical cable, whose 4 m standard length allows for the required safety distance. The plastic optical cable ensures perfect electric separation and reduces the effects of external electric noise. It does not conduct electricity.

Biocompatibility

To avoid infection risks, and for general hygienic reasons, the device, cuff and tubing should never contact the patient’s skin directly.

Hazardous materials

Used batteries qualify as hazardous waste and should be disposed of properly. OMRON monitors do not contain any materials quali ed as pharmaceutical substance or tissue of animal origin. They emit no material hazardous to humans.

Risk of incorrect diagnosis

The basic intended use of OMRON M24/7 monitors is to record blood pressure and pulse rate values. Patients should be informed about rules of cooperative behaviour; proper handling of the monitor used, and expected results of monitoring in advance. OMRON M24/7 monitors only provide data to support diagnostic decisions of a quali ed physician; they do not automatically provide a diagnosis of any kind. During the evaluation of recorded blood pressure values, possible artefacts due to external disturbances, motion artefacts, and electrical noise should be observed and handled with caution.

4.3. EMC Information

Medical electrical equipment should be used with precautions according to EMC, and must be installed according to the EMC notices disclosed in this manual as mobile RF transceivers could adversely affect it.
