Unobstructed

Unobstructed is an adjective meaning not blocked or hindered; free of obstacles or interference. It is used to describe spaces, views, passages, and processes that allow clear movement, observation, or flow.

In a physical sense, unobstructed spaces permit movement and sight. An unobstructed view is valued in real estate, theatre design, and photography because it ensures line of sight and openness. Building codes and design criteria sometimes specify unobstructed sightlines or access to essential features.

In medical contexts, an unobstructed airway is essential for effective breathing. Obstruction can cause respiratory distress and requires prompt treatment, while anesthesia and emergency care aim to maintain an unobstructed airway through techniques such as suctioning or intubation.

In engineering and the physical sciences, unobstructed flow refers to the movement of fluids or gases without impediments. Obstructions such as debris, valves, or rough surfaces can cause turbulence, pressure drops, or reduced efficiency in piping, ventilation, and hydraulic systems.

In astronomy and urban planning, an unobstructed sky or view means a clear line of sight to celestial bodies or the horizon, free from clouds, nearby structures, or light pollution. Weather, topography, and artificial lighting conditions influence how unobstructed a view remains.

The term derives from un- (not) + obstructed and is widely applied across disciplines to indicate freedom from blockage, interference, or impediment. Similar concepts include unblocked, clear, and unimpeded.
