This next stage is where the early problems start to arise. Your breathing becomes more labored and difficult, many patients describe it as feeling like they are drowning. The supplemental flow of oxygen you require increases significantly and you are given bronchodilators, a medication that makes breathing easier by relaxing the muscles in the lungs and widening the airways.
Unfortunately, this is not enough and your mobility starts to diminish quickly. Simple things like going to the bathroom or even sitting up in bed become too difficult and the decision is made to move you to the intensive care unit.
