Non-invasive Blood Pressure (BP) Monitoring Compared to A-Line BP Monitoring

NCT00739700 | Completed

Brief Summary

Blood pressure cuffs (NIBP) are slowly replacing intra-arterial (IABP) measurement as the standard of care in the medical intensive care unit. There is little data to support this clinical normalization of deviance. This study aims to correlate NIBP with IABP.

Conditions

Blood Pressure

Keywords

hemodynamics; blood pressure; blood pressure monitors

Outcome Measures

Primary Outcomes (1)

• Correlation between NIBP and IABP. NIBP is measured in both upper arms, both wrists, both thighs, and both ankles.

  All NIBP's are measured within 10 minutes.

Study Arms (1)

A

There is only one cohort of subjects, the critically ill. The NIBP will be correlated with the IABP in each subject.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Medical Intensive Care Unit patients with intra-arterial blood pressure catheters will be enrolled. Blood pressure cuff measurements will be made in both arms and both legs.

You may qualify if:

• Arterial blood pressure line

You may not qualify if:

• Lack of arms and legs for cuff pressures
• Medical or surgical indication that might prevent use of blood pressure cuffs
