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.
Claims9
A method for treating a patient having been intubated or tracheostomized, by inserting an endotracheal tube into the patient's trachea, thereby physically separating the upper airways from the lower airways of the patient, wherein said upper airways comprise all airways above the patient's vocal cords, and said lower airways comprise all airways below the patient's vocal cords, comprising the steps of:
- connecting said endotracheal tube to a ventilator;
- and
- transferring gases from the upper airways to the lower airways;
- wherein said gases include endogenous nitric oxide (NO).
