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.
Claims23
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- and
- introducing said collected gases and said inspiratory airflow to the patient;
- wherein said collected gases are collected by connecting the nasal airways of the patient to an aspirating device.
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- and
- introducing said collected gases and said inspiratory airflow to the patient,
- wherein said collected gases are collected by connecting at least one nostril of the patient to an aspirating device.
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- introducing said collected gases and said inspiratory airflow to the patient;
- and
- introducing moist air in the nostrils to prevent desiccation of the nasal mucosa.
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- and
- introducing said collected gases and said inspiratory airflow to the patient,
- wherein aspiration and reintroduction of air in the nasal cavity is synchronized with the breathing rhythm of the patient.
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- and
- introducing said collected gases and said inspiratory airflow to the patient,
- wherein air is blown out through the nasal airways in a manner mimicking normal exhalation.
A method for treating an intubated or tracheostomized patient, comprising the steps of:
- collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- introducing said collected gases to the inspiratory airflow of a ventilator;
- and
- introducing said collected gases and said inspiratory airflow to the patient, wherein said biologically active agent is endogenous NO.
An apparatus for collecting gases from a patient's upper airways and supplying said gases to inspiratory airflow of a ventilator or similar device connected to an intubated or tracheostomized patient, comprising:
- means for collecting gases from the upper airways of a patient to obtain collected gases containing endogenous NO;
- means for introducing said endogenous NO to inspiratory airflow of a ventilator;
- and
- a ventilator or similar device for introducing said collected gases and said inspiratory airflow to lungs of such a patient.
An apparatus for collecting gases from a patient's upper airways and supplying said gases to inspiratory airflow of a ventilator or similar device connected to an intubated or tracheostomized patient, comprising:
- means for collecting gases from the upper airways of a patient to obtain collected gases containing endogenous biologically active agents;
- means for introducing said collected endoqenous biologically active agents to inspiratory airflow of a ventilator;
- a ventilator or similar device for introducing said collected gases and said inspiratory airflow to lungs of such a patient;
- and
- means for introducing moist air into a patient's nostrils to prevent desiccation of a patient's nasal mucosa.
