Important Safety Information Important Safety Information This symbol on the Omron M24/7 monitor is a warning that you should read the accompanying documentation (this manual). Warning: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Caution: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury to the user or patient or damage to the equipment or other property. (General Usage) No user serviceable parts inside. The OMRON M24/7 monitor contains high complexity electronic and ne mechanical components. If you have any problems, please refer your monitor to quali ed service personnel.
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).

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.
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.
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. Normal status: time is displayed.
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.
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.
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.
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 10 second delay state: time is displayed but with no double-dot 1. measurement plan: 15/30 minute day/night intervals 2. measurement plan: 20/40 minute day/night intervals 3. measurement plan: 30/30 minute day/night intervals Programming in progress: blinking signal 2.7.
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.
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.

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.
