Dry powder inhalers feel restrictive?

Why do dry powder inhalers (DPIs) feel restrictive when you are trying to breathe in through them? This may be because they are optimized to control the flow of air as to maximize the amount of powder that is released. If you were to inhale too quickly, or too slowly, it may not reach deep within the airways. The dry powder particle size is a important factor and different inhalers will feel more or less restrictive. It's mostly a matter of "physics", to ensure that the medication is delivered to the airways in an optimal way. 🔗 Visit my website: https://www.toplunghealth.com/ 🎵 Listen to the podcast by searching "Top Lung Health" on your favorite podcast player or by going directly to Spotify: https://open.spotify.com/show/6VMTxUl...
