Abstract

An method and apparatus for delivering a humidified stream of gas to a young animal'"'"'s respiratory tract. The gas is delivered at a dew point temperature greater than the ambient dew point temperature. The apparatus is especially useful in the treatment of foal pneumonia.

Claims

1. A method for the therapeutic treatment of a young veterinary animal'"'"'s respiratory tract comprising the step of continuously delivering to the young veterinary animal'"'"'s respiratory tract a humidified stream of gas at a dew point temperature which is greater than the ambient dew point temperature at flow rates exceeding the veterinary animal'"'"'s peak resting inhalation rate to condition the veterinary animal'"'"'s respiratory, pulmonary and cardiovascular system.

2. The method of claim 1 wherein the step of delivering the humidified stream of gas further comprises delivering of the humidified stream of gas to a foal.

3. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering a humidified stream of gas in which the dew point temperature is also greater than the normal body temperature of the veterinary animal.

4. The method of claims 1 or 2 further comprising the step of adding a sedating agent to the stream of gas thereby preventing dehydration of respiratory and pulmonary airways and preventing water loss from the airway.

5. The method of claims 1 or 2 wherein the conditioning provided by the step of delivering the humidified stream of gas comprises increasing the peripheral blood circulation of the veterinary animal to warm-up without unnecessarily depleting energy and oxygen reserves.

6. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from bronchitis to condition the veterinary animal'"'"'s bronchi wherein the stream of gas deposits water to soothe inflamed tissue thereby preventing water loss from the veterinary animal'"'"'s respiratory tract allowing the animal to breath more freely.

7. The method of claims 1 or 2 wherein the step of delivery the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from a sinus infection to condition the veterinary animal'"'"'s sinus cavities wherein the stream of gas promotes opening and draining thereby increasing the blood flow in said infected sinus to promote healing.

8. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from an allergy wherein the stream of gas delivers filtered gas to the veterinary animal to facilitate mucous flow and promote the removal of irritants in the respiratory tract.

9. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from exercise-induced pulmonary hemorrhage to condition the veterinary animal'"'"'s respiratory tract wherein the stream of gas deposits water thereby thinning the mucous blanket, dissolving mucous plugs and promoting mucocilliary clearance.

10. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from pneumonia to condition the veterinary animal'"'"'s lungs wherein the stream of gas promotes mucocilliary clearance of fluids thereby increasing the blood flow in the pulmonary system.

11. The method of claims 1 or 2 wherein the step of delivering the humidified stream of gas further comprises delivering the stream of gas to a veterinary animal suffering from airway obstruction wherein the stream of gas deposits water on the walls of the respiratory tract thereby thinning the mucous blanket, dissolving mucous plugs, and promoting mucocilliary clearance.
