Abstract

The present invention restores the normal low-dose flushing of the lower airways with air from the upper airways, containing nitric oxide (NO) and possible other biologically active agents by aspiration of air from the upper airways and introducing said air in the inspiratory airflow of a ventilator. The inventive apparatus and method is free from the risks associated with traditional administration of exogenous NO.
