Making player specific bossbar

Is there a way to make bossbars that is set per person basis through using a scoreboard objective? I am trying to make an oxygen bar, and I want it to have a clear indicator and bossbar seemed the best indicator but from what I can see, there is no way to make it per player, as this is gonna be used in multiplayer by possibly multiple people, I am also down for suggestions to use as oxygen bar other than bossbar.
