Remote Patient

Wireless Finger Sensor

A low-pressure, disposable finger sensor measures continuous pulse pressure waveforms for PDA™ Algorithm Processing.

Pulse Decomposition AnalysisTM Technology

View patient data remotely with our realtime App, Secure Cloud, or HL.7 & SDK interfaces to EMRs and other platforms.

Automated Early Warning Scores, Charting, & Reports

Securely and Wirelessly collect data and monitor patients from anywhere using our realtime mobile App or Remote Monitoring Cloud Portal.

Pulse Decomposition Analysis Technology™ (PDA™) and AI Algorithms

Patented PDA technology and artificial intelligence algorithms derive continuous hemodynamic parameters by analyzing reflective pulsewave morphology within the arterial tree.

ICU-grade Accuracy and Clinical Validation

Numerous Clinical Studies have validated VitalStream™ and PDA™ non-invasive measurements against invasive A-Lines and catheters.

VitalStream is Clinically Validated to Continuously and Wirelessly Monitor:


Wireless, Non-Invasive SYS, DIA, MAP and Waveforms measured with every heartbeat using FDA-Cleared and Patented PDA™ Algorithms, validated against invasive A-Lines.


FDA Cleared, Rechargeable Wireless ECG Patch (Lead 2) with rhythm waveforms


Reatlime and Remote NEWS, NEWS2, or MEWS Early Warning Scores for notification of health deterioration


Up and Running with Hemodynamic Measurements in less than 30 seconds


FDA Cleared, Rechargable, Wireless End-tidal CO2 monitor (Side Stream)

"An amazing non-invasive device..."

“I’ve tried the Caretaker and it is nothing short of amazing. To realize this level of vital signs with a noninvasive device is incredible. The Caretaker can take patient safety in a hospital setting to a whole new level. For emergency services in the field, it provides an opportunity for more effective and immediate intervention. Caretaker should be standard of care everywhere!” – Dr Joseph L Hutchison, MD


"A big win for patient comfort and clinician productivity..."

“Caretaker’s ability to stream continuous blood pressure and vital information using only a comfortable finger cuff means I will no longer have to disturb my patients to ‘spot check’ vital signs using bulky wires, leads, or arm cuffs or deal with Alarm Fatigue associated. This is a big win for patient comfort and clinician productivity, not to mention the value of having realtime streaming data to make better clinical decisions without the “alarm fatigue” associated with in-room monitors” – Normand Dube, Trauma Nurse, RN, BSN, ACLS, PALS, BLS-I


"A real game changer..."

“Before Caretaker, most clinicians had to settle for intermittent ‘point-in-time’ Blood Pressure measurements using bulky arm cuffs, which can produce misleading results due to the influence of many factors such as movement, posture, anxiety, or caffeine. Caretaker’s ability to display a a series of Beat by Beat blood pressure measurements from a simple cuff is a real game changer, providing clinicians with more accurate data as they make treatment decisions.” – Dr. Jay Sanders, MD, Professor of Medicine (adjunct) at Johns Hopkins School of Medicine and President Emeritus of the American Telemedicine Association.
