CNAP® Technology
Full hemodynamics
at your fingertips
Bridging the gap with non-invasive and continuous parameters
Based on an easy-to-use dual finger sensor, the CNAP® technology provides a full set of non-invasively measured, continuous patient signals and hemodynamic parameters:
- CNAP® blood pressure (waveform, Sys, Dia MAP, PR)
- Advanced hemodynamics: Cardiac Output (CO/CI), Stroke Volume (SV/SI), Systemic Vascular Resistance (SVR/SVRI)
- Dynamic fluid management parameters: Pulse Pressure Variation (PPV), Stroke Volume Variation (SVV)
Non-invasive
Continuous and non-invasively measured data in real-time without any risk and burden to patients.

Continuous Blood Pressure
CNAP® blood pressure is measured non-invasively on the patient’s fingers by using the unique CNAP® finger sensor.
Continuous blood pressure measurement allows for the detection of rapid blood pressure changes often unidentified, missed or only belatedly recognized with intermittent NBP upper arm measurement.
One or more hypotensive episodes were detected during complex gastrointestinal endoscopy in 29% of the patients by using CNAP® technology. (1)
“Continuous non-invasive arterial pressure measurement facilitates detecting hemodynamic instability more rapidly and therefore may improve patient safety” (1)
- Preventing perioperative hypotension (1)
- Identifying unexpected and transient blood pressure drops in syncopal patients (2)
- Tracking of cardiovascular response to autonomic function tests and stimuli (3)

Non-invasive Cardiac Output & advanced hemodynamics
The non-invasive CNAP® finger sensor allows for accurate(1) and immediate feedback on hemodynamic and cardiovascular status in perioperative settings to support therapeutic decision making, and also to quantify hemodynamic response during orthostatic and autonomic function tests (tilt table, active standing, Valsalva, etc.)(2) or to track cardiovascular response to autonomic function test and stimuli (3).

Non-invasive Pulse Pressure Variation and Stroke Volume Variation parameters
PPV and SVV are dynamic fluid parameters enabling individualized intra-operative fluid management, supporting healthcare professionals in educated therapy decisions(1,2) over the course of Enhanced Surgical Recovery (ESR) and Goal Directed Therapy (GDT) guidelines to minimize postoperative complications(3,4).
