Perioperative Blood Pressure Monitoring

Publication date: Available online 7 May 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Joshua K. Roach, Robert H. ThieleAbstractArterial blood pressure monitoring is a major part of the decision-making process for every anesthetic. It is important to recognize the advantages, disadvantages, and limitations of available measurement modalities as well as have some understanding of the engineering principles on which these measurements are based. Oscillometry is by far the most common modality used, but is limited by its intermittent nature and inaccuracy during hypotension and hypertension. Arterial catheterization is the gold standard for measuring blood pressure, but is an invasive procedure that is expensive and not without risk of harm to the patient. The volume clamp and tonometric technologies are relatively new and allow for continuous noninvasive monitoring of the blood arterial waveform, but their accuracy in comparison with oscillometry is not well described and they have not been widely incorporated into standard practice. Additional research is needed to determine if continuous non-invasive blood pressure monitors can improve outcomes.
