I am now using the resperate for more than one month. At first not much changing but after several weeks and changing the time when i am using the machine (from during the day to before going to sleep..) my BP is going down. starting with 160/170 by 80/90 it's now after using the machine around 130/140 by 70/80. My question is: those lower numbers are after using the machine. Whats is the effect for the whole day. I measure before and after. I see a slight changing of the measurements before using the machine, going down at average a bit too. but it's now mostly between 1540/150 by 80/85. After the exercise its down to what I wrote above. (130/140 by 70/80). Is this normal and does it really help during the time i am not using the machine...? Anyone having helpful comments? Thanks a lot.....! Rudolf
