Spectroscopic Assessment of Tissue Oxygenation Changes During Vascular Surgery

Spectroscopic Assessment of Tissue Oxygenation Changes During Vascular Surgery

This study is a single-center, observational study designed to collect tissue spectrometric data related to tissue oxygenation.

A total of 30 participants, aged 18 or older, undergoing planned elective primary vascular surgery will be recruited in this investigation to assess the ability of the SpectroCor Tissue Oxygenation Monitor and its accessory SpectroCor Sensor to monitor peripheral tissue oxygenation perioperatively. The investigation is designed as an open, uncontrolled observational study in which the primary goal is to assess the Monitor's ability, in combination with the Sensor, to monitor tissue oxygenation and safety in routine clinical practice, reflecting the real-world patient population and treatment scenarios. Therefore, no control participants are needed in this investigation.

Inclusion Criteria:

• Adults, age of 18 - 90 years
• Scheduled for peripheral arterial bypass surgery.
• Scheduled for proximal arterial reconstruction.
• Ability and willingness to provide informed consent.

Exclusion Criteria:

• Inability to provide informed consent
• Considered a vulnerable person according to the Finnish Medical Research Act (488/1999), Chapter 2, Sections 7, 9, and 10, including retarded persons, pregnant women, nursing mothers, prisoners, and forensic patients.
• A known history of severe allergic reaction to nickel.
