VitalStream® for the ICU

Elevate care for your most critical patients with the only wireless, noninvasive hemodynamic monitor.

VitalStream is a wireless, noninvasive hemodynamic monitoring system that empowers you with the continuous data needed to help reduce complications and ICU length of stay (LOS). VitalStream uses AI algorithms and patented Pulse Decomposition Analysis to continuously measure over 20 vital sign parameters including blood pressure, cardiac output, stroke volume, systemic vascular resistance, fluid status and more.

The device can be fit, calibrated and monitoring within 90 seconds and uses an innovative low-pressure finger sensor that can be comfortably worn by awake patients throughout their entire hospital stay. VitalStream eliminates monitoring blind spots and provides you with the information you need to accurately assess volume status and titrate pressors or inotropes.

When caring for your sickest patients there’s no room for error. That’s why it’s imperative to have critical care monitoring devices that are precise and dependable. VitalStream has has been validated through all-comer studies and proven to provide accurate and reliable data across high-risk 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

The patient can just walk around with a wrist band.” ~ Aniket Rali, MD, FACC, FCCP, Advanced Heart Failure and Transplantation, Critical Care Medicine, Assistant Professor of Medicine and Anesthesiology, Vanderbilt University Medical Center

Why noninvasive hemodynamic patient monitoring in the ICU?

Even short periods of hypotension are associated with kidney and myocardial injury.3-5


of patients on IV fluid therapy suffer complications due to incorrect fluid administration.8


Spot checked blood pressure can lead to delayed event recognition and treatment, which can lead to adverse outcomes.5


Fluid overload is associated with a 29% increase in length of stay and a $15,334 increase in hospital costs per patient.9, 10


Hemodynamic instability is the second most common cause of ICU readmission at 31%.6 And hospital death rates are significantly higher for patients who are readmitted. 7

Take the guess work out of fluid assessment to drive better outcomes

Incorrect fluid administration can result in delayed recovery, increased length of stay, complications and costs. Around 50% of fluid boluses fail to improve cardiac output and perfusion.11 And fluid balance is an independent risk factor for 28-day mortality acute kidney injury.12

VitalStream offers near real-time continuous hemodynamic data that provides you with the information needed to accurately assess a patient’s fluid status. The fluid response feature allows you to quickly and easily identify if a patient is fluid responsive with the touch of a button. The percent of change calculations are done for you and fluid response is visually indicated.


Achieve SEP-1 reimbursement and improve sepsis outcomes

A 2022 study in CHEST showed that completion of all SEP-1 compliance elements is associated with a lower 30-day mortality rate a shorter LOS. 13 The sepsis treatment guidelines require 30 m/kg of crystalloid fluid to be given within three hours of sepsis identification and repeat volume assessment within six. But for some patients administering fluid or more fluid could be disastrous.

In the US, V5.14 of the Specifications Manual for National Hospital Inpatient Quality Measures includes guidance that you can document cardiac output, cardiac index, stroke volume or stroke volume index if a lesser amount of no fluids are ordered and still achieve SEP-1 measure compliance and reimbursement.

VitalStream enables you to quickly assess a patients fluid status and provides you with continuous CO, CI, SV and SVI data so you can the best treatment decisions for your patients.

Untether your patients for easier early mobilization

Studies show that early mobilization in the intensive care unit can have many positive effects including decreases in muscle atrophy, mechanical ventilation duration and length of stay.14 But timing is critical. Delayed mobilization of even a few days, can greatly impact outcomes. 15

VitalStream is the only FDA approved and clinically-validated continuous cardiac output monitor that eliminates cumbersome wires. The wearable formfactor, easily removable finger sensor and wireless Bluetooth capabilities all help enable easier early ambulation and therefore improved outcomes.
