Self-Applied Physiology
I’m reviewing cardiovascular and respiratory physiology for the Boards right now, and a little self-experimentation goes a long way. I have a little burst capillary in my cornea right now, and I’m pretty sure it’s from doing a Valsalva maneuver to refresh my blood pressure and heart rate physiology. And whenever I start reading about tidal volumes and functional residual capacities and dead space, I have this uncontrolled need to breathe really deeply.
Residual Volume is your friend! Without it your lungs would collapse and you’d die!
Hang in there!
