Autopress blood pressure monitors DPS-Promatic srl produce sfigmomanometri professionali dal 1988. Il modello nella foto si chiama Autopress Techno ed è il nostro attuale prodotto di punta. Negli ultimi vent'anni ne abbiamo prodotti altri modelli, spesso distribuiti con altri marchi, che sono oggi installati in oltre 3000 farmacie in Italia. Autopress Techno è disponibile sia con fascia da avvolgere manualmente, sia con bracciale completamente automatico, con preavvolgimento, per garantire una buona misurazione anche alle persone con braccia minute. DPS-Promatic manufactures blood pressure monitors since 1988. The model on the picture is Autopress Techno,our most recent production, but we have made many others, including some designed expecially for some customers to be distributed under other brand names. In total we have manufactured until now about 3000 blood pressure monitors in the different models. Autopress Techno is a competely automatic professional blood pressure monitor, that can be used to measure automatically people blood pressure in pharmacies or in physicians waiting lounges. It can works continuosly and it ensures the nominal accuracy of +/- 3 mmhg on the entire 0-300 mmhg range. Autopress Techno is available in the manual option (you need to wrap cuff around customer arm), or with the automatic cuff option (as in picture). |

Our previous production Abbiamo prodotto vari modelli di sfigmomanometri professionali. Nelle foto che seguono potete vedere Autopress Video, prodotto in varie versioni dal 1988 fino al 1999 e l'holter pressorio professionale Autopress 24, prodotto fino al 1998. We have produced many models of blood pressure machines. These are the most popular ones that you may have seen. AutoPress Video has been produced with slight modifications from 1988 to 1999. AutoPress 24 is our ambulatorial type blood pressure monitor, that has been produced until 1998 |

We manufacture blood pressure machines since 1988 and we are often asked explanations about the topics of blood pressure measurement. We have tried to put some useful information in the next lines.
What is blood pressure: it is the pressure of the blood in our arteries and veins. Our circulatory system has a pump that is the heart, for this reason blood pressure varies continuously.
SYSTOLIC blood pressure corresponds to the maximum pressure, it happens when the heart contracts and pushes blood into the arteries.
DIASTOLIC blood pressure corresponds to the minimum pressure that occurs between 2 consecutive heartbeats and is related to the elasticity of the circulatory system.
MAP is the Mean Arterial Pressure. To understand it, without discussing integrals of wave shapes, just consider that if the heart beats once a second, the actual pulse may last 1/10 of a second. Think about inflating a baloon with a bike pump: when you push you have a sudden pressure increase (systolic pressure condition), then the air will flow back to the pump pushing the piston upwards, in this phase the pressure decreases gradually until reaching a minimum when the piston is upwards (this is the diastolic pressure condition).
Imagine that you are pushing once a second applying 2P (a value 2 times the minimum, that we will call P), more or less you will have 2P for 1/10 of a second, then you will have a value in between, because the air is pushed back by the baloon resistance but there is the resistance of the Pump piston going upwards, let's say 1,5P for 3/10 of a second.
At that point you will have the minimum pressure, with the piston fully upwards, that lasts until you push again, so you have 1P for 6/10 of a second. If we now want to calculate the Mean Pressure that occurs between 2 consecutive pushes on the pump, it is 2P*1/10+1,5P*3/10+1P*6/10 = 1,25P.
This is the mean pressure value that persists in the system.
Going back to blood pressure, since the heart pulse shape is similar for everybody, it is a good aproximation to assume that MAP is equal to Diastolic + 1/3(Systolic-Diastolic).
This means that with a Diastolic blood pressure of 80 mmhg and a Systolic blood pressure of 120 mmhg, the Mean Arterial Pressure is about 93 mmhg.
What is mmhg? it means millimeters of mercury. It is the unit used worldwide to measure blood pressure.
