What we build
One small instrument on the line that’s already there.
CAPI, the Catheter-Attached Pressure Instrument, connects to an existing PICC or central venous catheter. No change to standard vascular access, no dedicated pressure line and no cable to the patient monitor.
Reusable electronic base
Holds the pressure-sensing hardware and wireless radio.
Single-use sterile sensor cap
Interfaces with the catheter. Replaced for every patient.
Wireless display
Live raw waveform and processed trend views.
Longitudinal record
Sessions saved and linked to a patient ID for review over time.
What the research shows
Bedside assessment alone misses what pressure data reveals.
Published research on heart failure and hemodynamic monitoring. These figures describe the clinical problem. They are not results of CAPI.
<50%
accuracy when physicians estimated RAP, PCWP and cardiac index from clinical assessment
Discordance between clinical assessment and invasive hemodynamics in advanced heart failure
~68%
of patients had their therapy changed once invasive hemodynamic data was available

Why CAPI
Fewer components.Continuous data.
How CAPI compares with a conventional wired pressure transducer setup.
| Traditional wired setup | CAPI | |
|---|---|---|
| Bedspace | Multiple connected components | Small, portable device |
| Connectivity | Cabled to the patient monitor | Wireless transmission |
| Data | Point readings on the monitor only | Readings, waveforms and trends over time |
| Access | Dedicated pressure-monitoring setup | Connects to an existing PICC or CVC |
| Model | Primarily disposable components | Reusable base and disposable sensor cap |
How it works
Four steps, no new procedure.
CAPI works with the central line the patient already has, so it fits into existing nursing workflows.
Connect
Attach the sterile sensor cap and reusable base to the patient’s existing PICC or CVC. No new line and no change to vascular access.
Careers
