“…In this way both the absolute BP values and the CW/ArmC ratios are taken into consideration. In agreement with Hutton et al [8], we propose to correct electronically the deviations of regression lines from the line of equality. In addition as far as infants are concerned, a programme for different cuff ratios should be introduced.…”

Some investigators found a good correlation between Dinamap and direct BPM [2,3,5,8,9,11,15,16,28], but most of these studies were performed on anaesthetised patients [2,28], in infants during heart catheterisation [3,4], or in groups of neonates and low birth weight infants [5,9,16]. There have been relatively few investigations involving the use of Dinamap for post-operative BPM in infants after heart surgery [19,25].…”

The accuracy of indirect oscillometric blood pressure measurements has been evaluated in 32 infants up to 11 months of age undergoing heart surgery. In a number of 1029 simultaneous measurements the indirect blood pressure was compared with the direct value obtained from a radial artery catheter. Cuffs of different sizes were applied. The main results were as follows: Regarding the ratio of cuff width to arm circumference, the best correlation between oscillometric and direct blood pressure measurements was obtained with a ratio of 0.38-0.41. The value of indirect blood pressure measurements depends on the absolute height of the blood pressure. In low blood pressure there is a tendency to underestimate and in high blood pressure there is a tendency to overestimate by the oscillometric blood pressure measurement. By applying an appropriate cuff size and by using our diagrams it should be possible to derive a direct value for the blood pressure on the basis of indirect oscillometric blood pressure measurements.

“…Oscillometric devices are widely used for this purpose and may give accurate assessment of mean arterial pressure, but are often inaccurate for registering systolic and diastolic pressure. 110,111 Blood pressure values obtained in acute care settings are unlikely to be useful for decisions on chronic hypertension management, 112 because of inadequate patient preparation, faulty equipment, 82 and the impact of the acute illness on blood pressure. Still, high readings recorded in the emergency room do predict hypertension on subsequent clinic visits, to some extent, 113 and warrant follow-up.…”

Abstract-Accurate measurement of blood pressure is essential to classify individuals, to ascertain blood pressure-related risk, and to guide management. The auscultatory technique with a trained observer and mercury sphygmomanometer continues to be the method of choice for measurement in the office, using the first and fifth phases of the Korotkoff sounds, including in pregnant women. The use of mercury is declining, and alternatives are needed. Aneroid devices are suitable, but they require frequent calibration. Hybrid devices that use electronic transducers instead of mercury have promise. The oscillometric method can be used for office measurement, but only devices independently validated according to standard protocols should be used, and individual calibration is recommended. They have the advantage of being able to take multiple measurements. Proper training of observers, positioning of the patient, and selection of cuff size are all essential. It is increasingly recognized that office measurements correlate poorly with blood pressure measured in other settings, and that they can be supplemented by self-measured readings taken with validated devices at home. There is increasing evidence that home readings predict cardiovascular events and are particularly useful for monitoring the effects of treatment. Twenty-four-hour ambulatory monitoring gives a better prediction of risk than office measurements and is useful for diagnosing white-coat hypertension. There is increasing evidence that a failure of blood pressure to fall during the night may be associated with increased risk. In obese patients and children, the use of an appropriate cuff size is of paramount importance.

“…For this purpose the CM5 configuration is preferable to other single lead systems. Arterial pressure may be monitored non-invasively in those patients undergoing minor surgical procedures, and the newer automatic systems provide more consistent and repeatable measurements than manual techniques (Hutton, Dye and Prys-Roberts, 1984). For major surgery, the advantages of direct arterial pressure monitoring far outweigh any minor disadvantages, and the method provides beat-by-beat information on the cardiovascular system.…”
