Effect enchantment: Is it possible to have a constant effect?

I use minecraft:tick in Effects to apply a constant effect when a piece of armor is worn (like the vanilla Turtle Helmet that gives 10 s of Respiration when head is in Air).
However, the timer always flickers. Like if it's 10 seconds, it shows 9 and 10 constantly. This is because I use min 10 and max 10.
I wonder if there's a "correct" way to set ti to a constant.
