Asthma black outline icon
Outlined human lungs with windpipe and short bronchial branches marking asthma airways
About the Asthma black outline icon
Two lungs are drawn side by side with the windpipe rising between them and short bronchial branches scattered across both lobes, marking inflamed airways. It reads instantly as breathing difficulty, respiratory illness and lung health. Use it on clinic websites, hospital department menus, inhaler and medication apps, health insurance forms, and biology or patient-education slides.
The outline keeps a wide, rounded outer contour with even stroke weight, so the small airway marks stay legible when scaled down. It sits naturally beside heart, kidney and stethoscope icons from the same anatomy set. Below 24 px, prefer the filled style.
This is the black outline version of the asthma icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
