What is “normal”? And why is establishing an individualised baseline so critical?
- When it comes to an individual patient’s measurement, “normal” can cover a wide range.
- Establishing an individualised baseline shows you where each patient’s physiologic “normal” range begins and ends so that you can customise care for that individual.
The INVOS™ system customises care for each patient's “normal.”
- The INVOS™ cerebral/somatic oximeter features a baseline setting that provides additional dimension and value to the rSO2 measurement.
- Combine this baseline with continuous monitoring and the result is critical, early warnings of developing pathology and deteriorating patient condition.,,,
- This is the kind of timely information you need—and can rely on—during surgery.
Unlike pulse oximetry, which measures arterial oxygen, the INVOS™ system measures rSO2, a reflection of cerebral venous saturation.
- This is an important distinction, because cerebral saturation has a much wider range of normal values (45% to 75%) than arterial saturation, which has a very narrow range.
- With this wider range of cerebral saturation, clinicians will make more informed decisions about intervention during surgery, based on the most individualised “normal” for each patient.
- The end result? Studies have demonstrated that intervening based upon a relative drop of rSO2 from baseline improved patient outcomes.,
