If you breathe through your mouth this could happen to you. Once upon a time after a steep uphill, I was winded and breathing through my mouth. I was still catching my breath on the downhill side while the bike accelerated into a fast run. Unfortunately my timing was bad and inhaled a bug. I couldn't breathe and didn't have enough air to cough. I wasn't sure if the bug was going to kill me or the fall after I passed out. After what seemed like a minute, I squeezed my stomach muscles hard and was able to grab a gasp of air. Not enough to cough but enough to move the bug into a swallowing position. Fortunately I survived but the bug was not so lucky.
