The Infinity® CNAP^™ (Continuous Noninvasive Arterial Pressure) SmartPod® provides a simple, accurate method for measuring systolic, diastolic and mean blood pressure. Simply slip the sensor cuff onto the patient’s fingers. Once applied, the patient monitor can continuously display the arterial pressure values and pressure waveform. CNAP offers a fast and simple way to create a continuous blood pressure reading.

• Simple application
• Reusable sensor cuffs – support saves on costly disposables
• Supported during in-hospital transport with Pick and Go® – conveniently mounted on an IV pole
• Improved time to intervention
• provides continuous measurements without requiring an arterial line
• High fidelity trending data – allow a comprehensive view of the patient’s status
• Adjustable alarm limits

The CNAP solution provides the clinical utility (i.e., beat-to-beat vigilance) of the invasive arterial line – with user convenience and simplicity of a noninvasive cuff. It bridges the gap in many situations when NBP is not enough, and an arterial line is just too invasive and complicated.

The CNAP system works by utilising photoplethysmograph sensors (light-emitting diode and detector) integrated into the sensor cuff. While the sensor detects changes in blood volume based on the amount of light transmitted through the finger, the cuff pressure closely follows the instantaneous pulsatile blood pressure changes in the finger arteries.

Blood pressure can then be calculated beat-to-beat, after calibration with the built-in standard oscillometric measurement (NBP) of the monitor – and a high resolution, real-time arterial pressure waveform is displayed.
