In Russian, there is a semi-colloquial medical term "рабочее давление" (working pressure) - the blood pressure that is excessive, but is typical for this particular patient and causes no symptoms in him/her.
For instance, a person may have a blood pressure of 140/90 chronically yet feel nothing out of the ordinary. In the past, doctors would say "it's just your working pressure, if you feel okay, your organism must have adapted". Today this is considered unscientific and is actively discouraged, but the colloquial term remains.
Problematically, the term tends to crop up in documents that a translator like me has to translate into English, so the translator has to come up with some English term.
I wonder if there is a term in English for this.
