Embodiments herein relate to devices and methods for assessing pulmonary congestion using optical sensing techniques. In an embodiment, a pulmonary congestion monitoring device can be included having a first optical emitter, wherein the first optical emitter can be configured to emit light at a first wavelength, such as at a near-infrared wavelength or an ultraviolet wavelength. The monitoring device can also include a first optical detector configured to detect incident light. The first optical emitter and the first optical detector can be separated by a distance of 1 centimeters (cm) to 10 cm. The monitoring device can be configured so that the light from the first optical emitter propagates through at least one of a lung tissue and an airway tissue. The monitoring device can also be configured to use detected incident light to determine a congestion status of the lung tissue. Other embodiments are also included herein.
