VitalStream® for Perioperative Care

Make better treatment decisions throughout the entire perioperative continuum with continuous hemodynamic data.

VitalStream is a wireless, noninvasive advanced hemodynamic monitor that can seamlessly bridge monitoring gaps throughout perioperative care. The innovative low-pressure finger sensor can be comfortably worn by conscious patients. This allows VitalStream to easily be placed on patients in preop so you can get baseline readings and save valuable time in the OR.

VitalStream uses AI algorithms and patented Pulse Decomposition analysis to measure continuous blood pressure (BP), cardiac output (CO), systemic vascular resistance (SVR), cardiac power (CP) and other physiological parameters. It can provide immediate insights in
near real-time for early detection of decompensation and enable early intervention.

Your patients are older and sicker than ever before so you need technology that’s precise and dependable so you can make the best treatment decisions and prevent complications. VitalStream has been validated through all-comer studies and proven to provide accurate and reliable data across high-risk surgical patient populations.

  • Demonstrated comparable accuracy to an arterial line and agreement the exceeds other commercially available CNIBP technologies. 1
  • Demonstrated good agreement against invasive thermodilution cardiac output in cardiac surgery patients. 2

VitalStream saves time, is safer and we have accurate readings.” ~ Zain Khalpey, MD, Cardiothoracic Surgeon, Director of Artificial Heart, MCS & ECMO, Chief Medical AI Officer (Network Director) at Honor Health

Khanna, MD, Intensivist and Anesthesiologist, and Vice Chair of Research at the Atrium Health Wake Forest Baptist Medical Center

Traditional blood pressure monitoring

Avoid dangerous blind spots in your next surgery

Traditional cuff-based monitoring only gives you intermittent snap shots of a patient’s blood pressure. That means, in a 90-minute surgery with spot checks every 5 minutes, you are missing a staggering 72 minutes (4,320 seconds) of critical data or 80% of the procedure! And even brief hypotensive events can trigger serious perioperative complications including acute kidney injury (AKI) and myocardial infarction (MI). 3,4

VitalStream provides continuous, beat-by-beat blood pressure measurements to eliminate blind spots throughout the entire perioperative continuum.

Reduce monitoring set up time by over 90%!

Reclaim over 13 minutes in your next surgery

Traditional radial artery setup for blood pressure monitoring can take a frustrating 15+ minutes. That’s precious time lost when minutes matter. This time can add up and translate into significant costs for your hospital. Improved OR efficiency can potentially improve on-time starts and lower operating costs. 

VitalStream noninvasive hemodynamic monitor can be set up in preop in just 60-90 seconds, measures central aortic pressures so there’s no need to level or zero upon position changes, and eliminates cumbersome wires.

Why continuous hemodynamic monitoring for perioperative care?

of non-cardiac surgical patients experience an intraoperative hypotensive event.4


Spot checked blood pressure can lead to delayed event recognition and treatment, which can lead to adverse outcomes.3


Postoperative complications are the third most common cause of death in the world.5

Tailor fluid administration for improved outcomes

Incorrect fluid administration can be disastrous and result in delayed recovery, increased length of stay, complications and costs. Positive and negative fluid balance increases the occurrence and progression of AKI after cardiac surgery.6 And volume overload is one of the five most common reasons for both acute and delayed readmission after cardiac surgery.7

VitalStream’s fluid response feature allows you to quickly and easily identify if a patient is fluid responsive. All you have to do is start and stop the timer with a push of a button. The percent of change calculations are done for you.


Enable early mobilization without sacrificing clinical insights


Early postoperative mobilization is a central tenent of Enhanced Recovery After Surgery (ERAS). Good compliance with ERAS pathway implementation is associated with improved outcomes including a reduced risk of complications, LOS and costs. The majority of ERAS guidelines strongly recommend early postoperative mobilization.8

The VitalStream noninvasive hemodynamic monitor eliminates wires to untether your patients. It enables early ambulation after surgery without sacrificing advanced blood pressure and vital signs monitoring.
