Quick and accurate blood pressure monitoring is essential to a patient under anesthesia as well as for those with certain medical conditions. Blood pressure is the driving force for blood flow (perfusion) through capillaries that supply oxygen to organs and tissue beds of the body. Low blood pressure results in decreased oxygen delivery, resulting in the death of important cells and organ damage, most sensitively the kidney and brain. Because lowered blood pressure is a common side effect of many anesthetic drugs, monitoring these values under anesthesia is crucial. High blood pressure poses many risks to our pets such as blindness (due to retinal detachment), kidney disease, heart failure and stroke. Proper medical intervention can save their lives and improve their quality of life.
