Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • ≥18 years
  • scheduled for elective low- to moderate-risk non-cardiac surgery with general anesthesia
  • planned intraarterial arterial pressure monitoring with a radial arterial catheter

Exclusion criteria

  • systolic arterial pressure interarm differences >20 mmHg
  • heart rhythms other than sinus rhythm
  • contraindications for finger-sensor arterial pressure monitoring (e.g., arteriovenous shunts, Raynaud's disease)
  • surgery in non-supine positions
  • pregnant patients.

Treatment and study plan

Arterial pressure monitoring

Device

We will record intraarterial arterial pressure, finger-sensor arterial pressure and oscillometric arterial pressure in all included patients.

Primary outcomes

  1. Difference in the agreement between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements, and the agreement between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements

    Time frame: During surgery

    To investigate whether the agreement between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) is better than the agreement between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements, we will perform Bland-Altman analyses.

Secondary outcomes

  1. Classification of measurement differences between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance

    Time frame: During surgery

    To classify measurement differences (mean arterial pressure and systolic arterial pressure) between finger-sensor arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance, we will perform error grid analyses.

  2. Classification of measurement differences between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance

    Time frame: During surgery

    To classify measurement differences (mean arterial pressure and systolic arterial pressure) between oscillometric arterial pressure measurements and intraarterial arterial pressure measurements according to their clinical importance, we will perform error grid analyses.

  3. Ability of finger-sensor arterial pressure monitoring to track arterial pressure changes compared to intraarterial arterial pressure monitoring

    Time frame: During surgery

    To investigate the ability of finger-sensor arterial pressure monitoring to track arterial pressure changes (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) compared to intraarterial arterial pressure monitoring, we will compute four-quadrant plots and calculate the concordance rate.

  4. Ability of oscillometric arterial pressure monitoring to track arterial pressure changes compared to intraarterial arterial pressure monitoring

    Time frame: During surgery

    To investigate the ability of oscillometric arterial pressure monitoring to track arterial pressure changes (mean arterial pressure, systolic arterial pressure, and diastolic arterial pressure) compared to intraarterial arterial pressure monitoring, we will computer four-quadrant plots and calculate the concordance rate.
