The DVM-4500 helps the surgeon to check the patency of the shunt or vessel right on the table: sensor in the sterile field, numerical flow, PI index, FFT curve and documentation of the result.
The model range according to the manufacturer's classification. Selection of the device and probes for the department — upon request.
Hadeco has been manufacturing ultrasound dopplers in Kawasaki since 1948, a niche, precision engineering tool for departments where quantitative measurement of blood flow is at the heart of a surgeon's or angiologist's decision. Discreet ergonomics, predictable sound, resource of the device.
DVM platform for cardiac surgery (CABG, AAA, heart transplant), neurosurgery and vascular surgery: blood flow quantification and PI index simply in the operating room.
Smartdop Platform for Angiologists, Vascular Offices and Diabetologists: ABI/TBI/Segmental Studies with Automated Cuff.
Three difficulty levels for angiosurgeons, obstetricians, emergency and family medicine doctors.
The pulsatility index is a key metric that the surgeon monitors immediately after the formation of the coronary anastomosis.
| PI | Interpretation | Action of the surgeon |
|---|---|---|
| < 3 | good Low resistance, good shunt permeability. | The shunt is acceptable — continue. |
| 3 – 5 | Borderline. Needs verification. | Assess anastomosis, kink and competitive flow with MGF and DF. |
| > 5 | bad High resistance to blood flow. | High probability of a shunt problem → revision of the anastomosis on the table. |
PI = (Qmax − Qmin) / Qaverage over 5 cardiac cycles — estimation of blood flow resistance. Interpret always in a complex: mean shunt flow (MGF) ≥ 20 ml/min and diastolic filling (DF) for left shunts usually > 50%. PI is affected by the quality of the anastomosis, distal stenosis, and competitive flow — the thresholds given are approximate, the decision is made taking into account the clinical picture.
40% improved Doppler sound — clear auditory assessment of blood flow even on weak signals.
FFT curve analysis, site guidance mode and data transfer to a PC (Smart-V-Link) for reports and tender documentation.
A complete line of probes — pencil, bayonet, flexible, ultra-thin 0.8 mm, flat monitoring, PPG and temperature probes.
We send the complete package in response to the institution's request.
Describe the profile of the department or the task - we will tell you the model, probes, availability and price for the tender, we will send the specification.
