Oscillometric Blood Pressure Measurement: Evaluation of the Effect of Wearing a Sleeve and the Type of Measurement Algorithm

Measurements of Arterial Blood Pressure With an Automated Oscillometric Cuff: Evaluation of the Effect of Wearing a Sleeve and the Type of Measurement Algorithm. A Prospective Observational Single-center Study With an Invasive Reference

Enrollment

Start Date

Study Type

OBSERVATIONAL

Conditions

Intensive Care Units

Summary

For accurate measurements of arterial blood pressure (BP), international guidelines recommend placing the automated oscillometric cuff directly on the bare upper arm. However, for various reasons, cuffs are often applied over a layer of textile. Whether this practice affects the reliability of the readings remains uncertain. Using a rigorous methodology, the CASBA study aims at addressing this issue. Additionally, two different BP measurement algorithms are available in some oscillometric monitors. To our knowledge, no study has compared the performance of these two algorithms. This study will help determine which oscillometric algorithm should be given priority in intensive care facilities.

Plain Language Summary

Simplified for easier understanding

This study looks at whether measuring blood pressure with a cuff placed over a sleeve of clothing gives accurate readings compared to placing the cuff on bare skin, as is currently recommended. It also compares two different measurement algorithms available in automated blood pressure monitors to see which is more accurate in a hospital intensive care setting. Adult patients in a surgical ICU who already have an arterial catheter (a direct blood pressure monitoring line) in their wrist are eligible, provided their blood pressure is stable and they have no cardiac arrhythmia or arm contraindications. Participation involves having blood pressure measured in different ways during a single session alongside your existing monitoring, with no additional invasive procedures required.
