As others have said this will come naturally by playing the game especially on Supernova.
If your like me and like to get the easy achievements out of the way just do this:
Start a game up, as soon as you land and are walking along following the prompts (tutorial). You get to a section where you jump down and are told you need medical aid and to use your Medical Inhaler.
*This can be done at anytime you have inhaler charges.
BEFORE YOU DO THIS SAVE YOUR GAME.
1.Now use the inhaler 11 times (LB). Save your game again in another slot. This updates the achievement tracker.
2.Now load your first save and use the inhaler 11 times again. Save to your second save.
3.Repeat till you get achievement takes about 20 minutes.
Edit: Per Kerman7 this carries over on multiple playthroughs.
