All

Inclusion criteria

Inclusion criteria: 1) Patients who will undergo arterial pressure monitoring during surgery 2) Patients who are 65 years of age or older at the time of consent 3) Patients with no abnormalities in the radial artery 4) Patients who can obtain written consent from themselves or their legal representative

Design outcomes

Primary

Measure	Time frame
Whether or not wrist exercise affects the arterial pressure waveform during arterial pressure monitoring	—

Secondary

Measure	Time frame
1) Poor visualization of arterial pressure monitoring waveforms during surgery 2) Poor blood collection 3) Vascular lumen stenosis 4) Need for splint fixation 5) Degree of discomfort (Numerical Rating Scale: (NRS)) (after admission to the intensive care unit) 6) Time until removal of arterial line (after admission to the intensive care unit (ICU)) 7) Time until discharge from the intensive care unit (after admission to the intensive care unit (ICU))	—
