MARCET DURAN, Montserrat et al. Evaluation of the continous monitoring of blood pressure by the HASTE function in patients under haemodyalisis. Rev Soc Esp Enferm Nefrol [online]. 2004, vol.7, n.2, pp.10-15. ISSN 1139-1375.

HAEMODYALISIS can produce episodes of haemodinamic instability leading to symptomatic episodes of hypotension. The HASTE function ofthe Colin monitor allows the non invasive monitoring of blood preassure using an algorithm that needs a precise ECG signal and the O₂ saturation wave. To validate the measurements of blood preasureusing the Colin monitor and to demonstrate its capacity to detect pre-symptomatic hypotensionusing the HASTE function, we performed a longitudinal descriptive study over 4 weeks. To validate the Colin monitor we compared the blood pressure measured every 30 minutes with the monitor and with a conventional method. To demonstrate the capacity of detection of presymptomatic hypotension, we selected a groupof patients with blood pressure equal or inferior to100/50 mmHg (30% of patients in the previous two months). We detected 57 episodes of symptomatic hypotension (27 in the conventional period and 30 during the Colin period). There were no stastistically significant differences. In conclusion, there are no statistically significant differences in the blood pressure measured by the two methods. The number of registers of blood pressure during the Colin period is under the thresold when the HASTE function is used.Symptomatic hypotensions during the conventional period are more pronounced and require more interventions from the nursing team.
