Abstract

A high humidity method and an apparatus are described which are useful for conditioning a pulmonary and/or a cardiovascular system in a large animal. The method broadly comprises delivering a humidified air stream at a dew point temperature greater than the environmental ambient dew point temperature to an animal'"'"'s respiratory tract.

Claims

1. A high humidity method useful for conditioning a pulmonary and/or a cardiovascular system in a large veterinary animal comprising

(i) providing a stream of gas;

(ii) heating water in a container means;

(iii) providing a porous membrane means disposed within said container means, said container means adapted to permit liquid droplets to contact said porous membrane surface to permit a vapor to defuse therethrough;

(iv) mixing said vapor with said stream of gas to humidify said stream of gas;

(v) delivering said humidified stream of gas at a rate from greater than about 60 to about 500 liters per minute to the animal'"'"'s respiratory tract at a dew point temperature greater than the environmental ambient dew point temperature, said humidified air steam dew point temperature is within the range of about 99°

F. to about 110°

F.

2. A high humidity method of claim 1 wherein

(i) a humidified air stream at a dew point temperature greater than the environmental ambient dew point temperature

(ii) said humidified stream of gas is delivered in the substantial absence of nebulized water aerosol.

3. A high humidity method of claim 2 wherein

(i) said humidified air stream is delivered at a dew point temperature greater than 93°

F. (33.9°

C.).

4. A claim 1 method wherein (i) the humidified air stream is delivered continously.

5. A claim 4 method wherein (i) the humidified air stream is delivered continously for a time period of less than about 24 hours.

6. A claim 5 method wherein (i) the humidified air stream is delivered continuously for a time period of less than about 8 hours.

7. A high humidity veterinary therapy method useful for conditioning pulmonary and/or cardio-vascular system in veterinary animals comprising delivering a humidified air stream at a dew point temperature within the range of about 99°

F. to about 110°

F. temperature and less than a permanent tissue damage temperature of an animal'"'"'s central nervous system, said humidified air stream is delivered at a rate from greater than about 60 to about 500 liters per minute.
