24 Hour Blood Pressure Monitor

By choosing a blood pressure monitor accuracy of the instrument should be the most important consideration. Secondly, the reliability measures should be considered. Thirdly, the usability of the device must be taken into account.

Accuracy refers to the extent to which blood pressure readings obtained truly reflects the actual pressure in the arteries when the readings are made. Reliability on the other hand, refers to the extent to which blood pressure reflects the mean blood pressure within 24 hours.

The technique of the person making the measurements, the attributes of the meter, and the selection of the arms are the main variables that determine the accuracy. The frequency of surveys, recording the reading and understanding the many factors that can influence blood pressure are the main variables that determine the reliability of readings.

One of the most common reasons for an inaccurate reading is poor positioning of the arm in relation to the heart when a reading is in progress. If the reading is taken with the arm hanging well below the level of the heart that reading may be falsely elevated pressure that is true, and if the arm is positioned higher than heart level reading is likely be falsely low. Incidentally, if the arm is not supported by a fixed structure, like a booth or another person if someone else in the scene of reading, but is held in position against gravity by the person that reading is done, a certain degree of isometric exercise is performed can affect the reading. While achieving proper arm positioning is a problem with the wrist monitor Omron patented technology advanced position sensor is a likely solution. The device notifies you via a tone characteristic and will not begin to read at all if the arm is not in the correct position. It allows you to take readings sitting and lying, knowing that the accuracy of your readings is not compromised by the incorrect position of the arm. Since reading session is performed with the arm bent at the elbow and supported by the hand of the arm contralateral isometric exercise is not performed during playback.

Another very common cause of an invalid blood pressure is a bad cuff size in relation to the circumference of the upper arm. Generally, if the cuff size is too small compared to the circumference of the arm of the reading will be higher than the true blood pressure. Conversely, if the cuff size is too big for the arm circumference of the reading will be lower than the actual pressure. The cuffs used for measurement arms come in adult sizes of many. There is no standardization of size between manufacturers, but for convenience are primary sizes adult large adult and thigh. Some manufacturers also produce an extra-large adult size is the size of the two large adults and thighs. To ensure use of appropriate cuff size of the American Heart Association recommends that you measure the circumference of your arm and select a cuff with a large arm circumference explained that understands your position. If your arm circumference is greater than the largest cuff available, you should consider a wrist monitors, which usually accommodate a wrist circumference of 13.5 cm to 21 cm or 5.25 inches to 8.5 inches.

If the cuff is not inflated high enough before the deflation began reading could be lower systolic blood pressure true. If inflation and deflation process is interrupted, and repetitiveness of the overall reading is likely to be inaccurate. To eliminate the inaccuracies associated.
