Continuous non-invasive monitoring improves blood pressure stability in upright position: randomized controlled trial

Measurement of blood pressure

“…However, regarding the simplicity of use and the absence of risks, certain patients might benefit from continuous noninvasive BP monitoring using the CNAP system compared with intermittent oscillometric measurements, as recent studies have shown. A randomized controlled trial showed that the time spent in hypotension was significantly shorter using continuous CNAP monitoring compared with oscillometry in patients undergoing thyroid surgery in an upright position [58]. The CNAP system improved the detection of fast BP changes in patients receiving sedating agents during interventional endoscopy [59].…”

“…Noninvasive continuous BP monitoring technologies can improve patient monitoring during interventions and in the operating theatre [58][59][60]. In order to raise the acceptance and application in clinical routine, the next most …”

Year in review in journal of clinical monitoring and computing 2014: cardiovascular and hemodynamic monitoring

“…For patients being treated on an intensive care unit (ICU), no data have been available so far regarding the applicability of functional hemodynamic monitoring. In the issue of June, Benes et al retrospectively reviewed 1296 patients admitted to their ICU for a wide variety of diseases and over a time span of 5 years [4]. They found that within the first 24 h of treatment, 549 patients (42.4%) fulfilled all ,,major''-criteria for the applicability of dynamic preload indicators (sedation, absence of arrhythmias and controlled ventilation with a tidal volume above 8 ml/kg).…”

When should we adopt continuous noninvasive hemodynamic monitoring technologies into clinical routine?

“…But what is the right way to go with regard to clinical validation and evaluation studies from the technology's first introduction to its medically useful application on a routine basis? From the article by Benes et al [1] a general recommendation for a reasonable approach in order to answer this question can be derived.…”

“…Instead, we should rather focus on patients who do not receive continuous hemodynamic monitoring but intermittent blood pressure measurements using oscillometry. Benes et al [1] rightly decided to include low and intermediate-risk surgical patients during thyroid surgery in beach chair position. Thereby they offer us an excellent example for the possible use of noninvasive continuous blood pressure monitoring as a reasonable alternative to intermittent oscillometric blood pressure measurements in the perioperative setting.…”
