Respiratory problems in horses can account for a significant percentage of the adverse causes that may temporarily or permanently reduce the anticipated performance levels of up to 75% of the racetrack, work and pleasure horse population. Respiratory diseases may take different forms throughout the life of a horse.

Yearlings and two to three year olds, entering the racetrack, are most susceptible to influenza and rhinopneumonitis. The equine ventilatory environment and exposure to recurring viruses may cause coughing and decreased airway responsiveness lasting from a few days up to several months.

Progressive clinical signs of this disorder are persistent with intermittent cough, poor exercise tolerance, appearance of an abdominal lift and finally severe respiratory distress. 

The Equine Aero Mask has been designed to be used with metered dose inhaler medicated particles or wet nebuliser aerosols by directly targeting the airway and lungs.

The Equine Aero Mask provides a targeted method of delivery by accurately directing concentrated medication to the lungs and small airways. The Equine Aero Mask also effectively regulates dosage and significantly reduces systemic side effects. The initial goal of therapy is to control inflammation and reverse airflow obstruction. Once the horse is stabilized, a preventative maintenance program can be can be implemented.

The lightweight Equine Aero Mask system offers a unique way to deliver inhaled medications using either metered dose inhaler or wet aerosol technology. The mask is made of a sturdy transparent polycarbonate, features a silicone seal and valves for inspired and expired air. When fitted over the horse's nose, an MDI chamber with an MDI canister is attached to the inhalation valve, at the front of the mask. 

By depressing the MDI canister, the medication is propelled into the chamber, through an inspiratory valve, and into the mask to be inhaled as the hose takes a normal breath. In a similar manner, when a small volume nebulizer with aerosol holding chamber is attached to the inhalation valve, the wet aerosol is inhaled as the horse takes a normal breath. Some dry powder inhalers will also attach directly to the inspiratory valve and the horse will inhale the medication in a normal breath.

Wash with mild soap and water between uses is suggested but otherwise maintenance is not required, although occasional replacement of the valves is recommended. To avoid cross contamination it is best to have a mask for each horse.
