As intrapulmonary (from the Latin. Intra "in" and pulmo " lung ") refers to things within the lung.

The term is also used for the application of drugs to the lungs. This is possible, for example, by inhaling an aerosol , with the drug usually only penetrating into the bronchi . This procedure is mainly used for drugs that act locally on the bronchi, e.g. B. in asthma . An intrapulmonary injection is a form of application that is only used in absolute emergencies as a replacement for an intravenous injection, when no vein can be found with very low blood pressure or in very small animals. To do this, a needle is inserted through the thorax into the lungs. The high resorption capacity of the lungs is used, which guarantees a quick effect of the drug.
