Most chronic asthmatics have on hand a portable asthma pump. Air is pumped via a plastic tube to the nebuliser which is attached to a plastic face mask. The mixture of air and Ventolin is then breathed in. The problem from a Covid scenario is that the face mask has two cutaway sections allowing the person to inhale and exhale. I have seen the mixture exhaled to a distance of a metre or a little more .
