The vascular part of Max Pulse is based on photoplethysmography – optical sensing of the pulse wave at the fingertip. The shape of that wave gives orientation about vascular elasticity and circulation. This article explains what the pulse wave is, why vessels stiffen and how to read the vascular output so it works as prevention, not as a replacement for a medical exam.
With every heartbeat a volume of blood is ejected into the arteries and a pressure wave runs along the vessel wall. It travels far faster than the blood flow itself, and its speed and shape depend mainly on the elasticity of the vessel wall. The more elastic the vessels, the better they cushion the wave; the stiffer they are, the faster and sharper the wave travels.
Photoplethysmography captures this wave optically: light passing through the finger changes with how much blood is in the vessels at a given moment. From a one-minute resting recording the device builds the pulse curve and derives orientation indicators about vascular state from its shape.
An elastic arterial wall helps keep pressure even. With age, compliance naturally declines – connective tissue, especially collagen, builds up in the wall and arteries stiffen. This is a normal process that lifestyle can slow down or, conversely, speed up.
Elasticity is also worsened by fatty and atherosclerotic deposits, cholesterol buildup, high blood pressure, smoking, obesity, diabetes, physical inactivity and long-term stress. In men the risk appears earlier than in women before menopause; after menopause the difference fades. When vessels stiffen, the demand on the heart rises and it is under greater long-term load.
Max Pulse classifies the most common wave shape into one of seven types. Type 1 is the most favorable and reflects good circulation and vascular elasticity. From type 3 upward there is a suspicion of a worsening state – early vessel stiffening often linked to stress, lifestyle, smoking or excess weight. Types 5 to 7 indicate more pronounced circulation problems and a worse vessel state.
Alongside the dominant type you also see a "vascular status" – a percentage distribution across levels labeled from Excellent to Very poor. That helps tell whether the picture is clean (mostly in one favorable level) or scattered across several.
The vascular report lists two elasticity values on a Sub-optimal / Normal / Optimal scale. AE is the elasticity of arterial (larger) vessels and PE the elasticity of peripheral (smaller, outer) vessels. For both, a higher value reflects better elasticity.
These values are orientation context, not a diagnosis. They are shaped by age, lifestyle and the day itself, so the trend across several similar measurements says more than a single number. Note: older device materials listed three indices (EC/AE/RBV); the current Czech software version works with two – AE and PE.
Atherosclerosis is the thickening and reduced elasticity of an artery due to deposits of fatty substances, blood cells, connective tissue and, secondarily, calcium in the vessel wall. It reduces blood flow and can lead to serious complications – coronary heart disease, heart attack, stroke or lower-limb artery disease.
The Max Pulse vascular output does not diagnose atherosclerosis. But it can flag a worsening elasticity trend before it shows up elsewhere, supporting prevention. If the result is unfavorable over the long term or symptoms appear, that belongs with a doctor, not just in wellness tracking.
Prevention is the most effective tool for vascular elasticity, and it largely overlaps with what is good for the heart overall. The key levers are diet, movement and reducing risk factors – which is exactly where it makes sense to connect the vascular output with nutrition coaching and with InBody.
General recommendations: limit saturated and trans fats and excess salt, increase fiber, unsaturated fats and folate, stay active, do not smoke, limit alcohol and watch weight and blood pressure. No single measurement replaces these steps, but a repeated trend helps show whether the changes are working.

FAQ
No. The vascular part reads orientation elasticity and pulse-wave shape; it is not a diagnostic vascular exam. With an unfavorable trend or symptoms, confirmation belongs with a doctor.
Both describe elasticity, just at different levels of the vascular tree – AE in larger arteries, PE in peripheral vessels. They are read together, and for both a higher value is more favorable.
Part is set by age and genetics, but modifiable factors play a big role: movement, diet, not smoking, weight, blood pressure and stress. A trend across repeated measurements helps tell whether the changes are helping.
For trend tracking it makes sense to measure repeatedly under similar conditions rather than react to a single deviation. The exact interval depends on what you are tracking – the article on when to measure Max Pulse covers more.
The vascular part of Max Pulse makes the most sense as a trend and alongside InBody, blood pressure and lifestyle. It helps you see early whether vascular elasticity is holding or declining.
