What It’s Really Like Inside a Hyperbaric Chamber?

So once you're in the chamber, how long does it take for the tube to pressurize to where you start your timer? That depends on how deep you're going or how much pressure you're putting into the machine. So when you're going up to 2 atmospheres, that's going to take roughly 15 minutes of you constantly readjusting your ears like you're going underwater. Like, you pop your nose and you pop your ears through breathing through your nose, that type of pressurization takes that long. But if you're doing 1.3 atmospheres, it might be like three to four minutes after you've adjusted, it feels fine. It doesn't matter what pressure at it feels like. You're just completely regulated at that pressure, and then all you do is breathe. You breathe, you work on your phone and you meditate.
