Summary

The present study was designed to assess, in a population of patients admitted to the intensive care unit and already carrying an indwelling arterial catheter, the ability of combined continuous (ClearSight™) and intermittent (automatic cuff) non-invasive monitoring to detect low mean BP (\<65mmHg). The intra-arterial measurement will be the reference measurement. As secondary objectives, the investigators will assess the ability of combined continuous (ClearSight™) and intermittent (automatic cuff) non-invasive monitoring to detect stage 2 hypertension, and to detect changes in BP during a cardiovascular intervention (as clinically indicated but not imposed by the study protocol). Additionally, the accuracy of both devices against the current international standard (ISO standard) will be assessed.

Conditions

Interventions

DEVICE

Combined non-invasive intermittent (oscillometric arm cuff), non-invasive continuous (finger cuff and ClearSight device), and invasive continuous (intra-arterial catheter) BP measurements

Continuous (finger cuff) noninvasive and invasive BP measurements, over a 30-min period. Pairs of noninvasive/invasive BP recorded each minute). In the same time, 3 pairs of oscillometric NIBP (cuff placed around a calf), and invasive BP measurements, at 30-sec intervals. The cuff is then placed around an arm and triplets of BP (arm cuff, finger cuff, intra-arterial catheter) will be taken over a 20-min period, at 3-min intervals and every time the invasive and/or the continuous finger cuff measurements cross the threshold of 65 mmHg for the mean BP. If clinically indicated, a cardiovascular intervention that can be either vascular volume expansion or initiation of vasoactive drug therapy, can be administered during this period. Finally, the cuff placed around the arm will be once again placed around the calf to take 3 pairs of oscillometric NIBP measurement with cuff placed around a calf, and simultaneous invasive BP measurement, at 30-second intervals.
