Blood pressure monitor accuracy during surgery

This study compares two places to put a small tube (arterial line) that measures your blood pressure during surgery. The goal is to see which location gives the most accurate readings to help guide your anesthesia care.

This study tests a new device that measures blood pressure continuously without needing a needle in your artery. If you are having surgery and already need an arterial line, this device might offer a less invasive way to track your blood pressure during the procedure.

This trial tests a device that monitors blood pressure continuously during surgery using a finger cuff, instead of the standard arm cuff that gives readings every few minutes. You may be able to join if you are having surgery and are at higher risk of complications during anesthesia.

This study tests how accurately a non-invasive blood pressure device measures your pressure compared to a direct measurement from an arterial line (a thin tube in an artery that directly measures pressure). You'll need to be in a hospital or intensive care setting where you already have an arterial line as part of your standard care.

This study checks whether a non-invasive blood pressure device can measure blood pressure accurately in ICU patients right after cardiac surgery. It compares the new device to standard invasive monitoring through an arterial line or catheter.

This study tests how well a new blood pressure cuff measures blood pressure compared to a standard arterial line. If you already have an arterial line as part of your care, you may be able to help us see if the cuff is accurate.
