简要总结
This study will establish the feasibility and preliminary validity of real-time oxygen delivery index (DO₂i) monitoring using noninvasive hemoglobin (SpHb, Masimo) and minimally invasive cardiac output (FloTrac, Edwards) in cardiac surgery patients.

研究组 & 干预措施
Cardiac surgery patients
The study uses a within-patient repeated-measures design, where each patient serves as their own control across the three timepoints. The following measures will be recorded:
- SpHb, Perfusion Index, SpO₂ from Masimo Radical-7 (timestamp to HH:MM:SS)
- FloTrac cardiac index from Edwards HemoSphere
- ABG hemoglobin, SaO₂, PaO₂, and lactate from ABL analyzer
- Continuous cardiac index from Swan-Ganz catheter
- Mean arterial pressure, heart rate and rhythm
- Patient temperature from the bladder
- Pressor requirements
干预措施: SpHb monitor (Device)
