Pressure in mmHg: understanding pressotherapy settings
On a pressotherapy device, pressure is expressed in millimetres of mercury (mmHg). What this unit means and how to choose the pressure level and compression mode.
The mmHg unit
The millimetre of mercury is the unit used for blood pressure and for the pressure of compression devices. To convert: 1 bar is approximately 750 mmHg, so 100 mmHg corresponds to approximately 0.13 bar.
Choosing the pressure level
Low pressure is suitable for maintenance, prevention and sensitive clients. Moderate pressure is used for heavy legs and recovery. High pressures are reserved for specific, often medical, cases. Always start low and increase gradually according to how it feels: the session should not be painful.
Sequential or progressive mode
In sequential mode, the compartments inflate one after another, from the ankle to the thigh: this creates a wave that pushes fluids upwards, ideal for drainage. In progressive mode, all compartments build up pressure together: the effect is more enveloping, often appreciated for comfort and maintenance. The Presso+ offers both.
Duration and frequency
The higher the pressure, the shorter the session should be and the more widely spaced the sessions. Moderate pressures allow longer and more frequent sessions.
Warning signs
Tingling, numbness, sharp pain or pale feet: reduce the pressure or stop the session. In the case of severe varicose veins, clotting disorders, severe hypertension or recent phlebitis, medical advice is needed before starting.
