Omboni, Stefano, Gianfranco Parati, Antonella Groppelli, Luisa Ulian, and Giuseppe Mancia. Performance of the AM-5600 blood pressure monitor: comparison with ambulatory intra-arterial pressure. J. Appl. Physiol. 82(2): 698–703, 1997.—The AM-5600 is a new device that simultaneously monitors electrocardiogram (ECG) and noninvasive blood pressure (BP) over a 24-h period. BP readings (Korotkoff sounds and cuff air pressure) are stored into the recorder, allowing the removal of BP artifacts after a visual check. In 12 subjects with essential hypertension, we compared BP values simultaneously provided by the AM-5600 and intra-arterial recordings. At rest, noninvasive systolic BP (SBP) values were lower (5.4 ± 4.9 mmHg) and diastolic BP (DBP) values were higher (7.3 ± 7.3 mmHg) than were intra-arterial values. In ambulatory conditions (9 subjects), between-method discrepancies were +0.8 ± 6.1 and +12.2 ± 7.4 mmHg for 24-h SBP and DBP, respectively. AM-5600 underestimated 24-h intra-arterial SBP and DBP SD, but it accurately tracked intra-arterial SBP and DBP changes. Editing removed 22.1% of total readings, slightly reducing between-method discrepancies. Thus the AM-5600 provides an accurate average estimate of resting and ambulatory SBP and, for DBP, a less accurate estimate that is slightly improved by editing. The AM-5600 allows accurate description of SBP and DBP profiles and thus may be suitable to describe the abrupt BP changes accompanying a number of clinical events.

The purpose of this study is to evaluate the accuracy of an oscillometric blood pressure monitor in anesthetized pigs. Invasive blood pressure (IBP) and noninvasive blood pressure (NIBP) measurements were taken using a DRE Waveline Pro multiparameter monitor at four different time points in 17 pigs undergoing injectable anesthesia. NIBP measurements were taken on both the thoracic and pelvic limbs. Bland Altman analysis was used to assess agreement between methods and a linear mixed-effects model was used to evaluate the effect of cuff position and blood pressure on bias. Invasive systolic arterial pressure (SAP) ranged between 112 and 161 mmHg (mean ± SD: 138.8 ± 13.3; median: 139.5). Invasive diastolic arterial pressure (DAP) ranged between 60 and 104 mmHg (mean ± SD: 86.0 ± 9.1; median: 87.0). Invasive mean arterial pressure (MAP) ranged between 79 and 121 mmHg (mean ± SD: 103.2 ± 9.3; median 103.0). Only the diastolic and mean measurements obtained from the pelvic limb met criteria outlined by the American College of Internal Medicine for required accuracy of NIBP monitors. Bias was significantly higher in the thoracic limb in comparison to the pelvic limb and was significantly higher at blood pressures above median. In general, NIBP measurements underestimated IBP measurements. In conclusion, the use of the DRE Waveline Pro to assess NIBP in anesthetized pigs may be useful in monitoring trends in mean and diastolic blood pressure and is most accurate when used on the pelvic limb.

The Impact

Abstract Hierarchical linear regression (HLR) can be used to quantify the relative contribution specific cardiovascular (CV) mechanisms make to blood-pressure responses. The impact particular mechanisms exert varies depending on the nature of situational demands and the length of time these demands have been imposed. Theoretically, the determinants of blood-pressure changes may exercise their influence independently as simple effects, or they might evidence a relationship that is correlated or shared with other mechanisms. Following a procedure Lindenberger and Potter (1998) outlined, we used HLR and computations of shared versus simple effect ratios to quantify the portions of variance several cardiovascular parameters accounted for independently in mean arterial pressure (MAP) reactivity during isometric handgrip and mirror tracing. The predictor variables included heart rate (HR), total peripheral resistance (TPR), and cardiac output (CO). CV activity of 50 college-aged males was measured during adjacent 30-s periods using impedance cardiography and a Dinamap blood pressure monitor. HR reactivity predicted MAP changes during all measurement periods. However, for mirror tracing, a substantial portion of the variance in MAP accounted for by HR was shared with CO reactivity (39% for period 1; 13% for period 2). For handgrip, 5% and 20% of variance HR accounted for in MAP during periods 1 and 2, respectively, were shared with changes in TPR. CO shared trivial amounts of variance in MAP changes with HR during handgrip. Finally, CO changes were correlated with TPR changes and uncorrelated with MAP reactivity when handgrip was performed. However, adding CO to the equation improved TPR's predictive utility, suggesting that suppressor effects were present.
