From time to time, medical professionals share their thoughts about the use and benefits of the INVOS^® Cerebral Oximeter. Here's what they are saying.

"The low INVOS Cerebral Oximeter readings were relatively easy to correct, and the decrease in neurological injuries and renal failure was reflected in reduced length of stay. These findings suggest that inadequate brain oxygenation resulting in neurological dysfunction may be responsible for injuries that are preventable, resulting in reduced length of stay.

"We have previously reported that cerebral oxygen desaturation is associated with neurological complications and prolonged lengths of stay in the intensive care unit and hospital following cardiac surgery. Therefore, it is prudent to monitor and maintain adequate oxygen saturation during cardiac surgery for the patient's health. Now we have demonstrated that maintaining adequate oxygen saturation during cardiac surgery significantly shorted ICU and hospital stays, so we believe using cerebral oximetry may decrease the total costs of surgery."

"Without specialized monitors, blood pressure has been a widely-accepted estimate of blood flow to the brain, although an admittedly indirect measure. Our study is a demonstration of the potential risks associated with that approach. Using blood pressure as an estimate of adequate blood flow to the brain is frequently incorrect and misses some transient declines in brain oxygen that occur.

"Cerebral perfusion during cardiopulmonary bypass may be inadequate at times. Unless there is a tool to measure the adequacy of cerebral perfusion, these changes will go unnoticed and may lead to perioperative stroke. The Cerebral Oximeter alerted us to clinical situations that up to now we had no good way to evaluate. This information led to corrective action to avoid stroke while on cardiopulmonary bypass. These beneficial effects were achieved using techniques that are noninvasive, inexpensive and safe."

"We use the Cerebral Oximeter on all carotid surgeries. The surgeons refuse to proceed without it."

"The biggest effect the Cerebral Oximeter has had in our hospital is that it has increased and improved our interactions with the anesthesiologist in the management of the patient perioperatively. The cerebral saturation number has impacted our technique and has improved patient care."
