Brief Summary
The purpose of this study is to compare blood pressure values (systolic, diastolic, mean arterial pressure) and waveform as recorded by a radial arterial line catheter to the waveform and values as calculated by the Sensifree's algorithm from a PPG sensor from a variety group of patients during elective surgeries.

Outcome Measures
Primary Outcomes (1)
Comparison of waveforms and BP values between PPG sensor and arterial line
Blood pressure waveform will be acquired from the PPG while blood pressure waveform and values (systolic, diastolic, mean) will be acquired from A-line. PPG data will be analyzed by the Sensifree's algorithm and compared to the A-line measurement results according to ISO 81060-2 accuracy specifications

Interventions
Invasive monitoring of blood pressure via catheterization of the radial artery, displaying a continuous pressure waveform
PPG based, fingertip mounted sensor, that measures the oxygen level (oxygen saturation) of the blood and generates a waveform
A blood pressure cuff is used to measure blood pressure. The cuff has an inflatable rubber bladder that is typically fastened around the arm. A pressure meter indicates the cuff's pressure.
Eligibility Criteria
Patients scheduled for elective surgery involving placement of radial artery A-line for BP monitoring
You may qualify if:
- Signed inform consent
- Age 18-20
- Elective surgery that requires invasive BP monitoring (A-line)
You may not qualify if:
- Emergency surgery
- Subject has a condition that might prevent BP fluctuations
- Subject is taking medicine that might prevent BP fluctuations
- Arterial line not placed in the radial artery
- Flush test has inadequate frequency response pre-trial
- Subject's arterial line contralateral hand is not available for PPG sensor placement
- Subject has 50% or more pacemaker dependency
