Respiratory failure may occur due to a decrease in the amount of arterial oxygen and an increased amount of carbon dioxide in the blood. Anesthesia and intubation by positive pressure ventilation is lifesaving. Veterinary respiratory ventilators are of two types, viz. long-term mechanical ventilation and short-term ventilation. Veterinary respiratory ventilators provide oxygen supplementation and carbon dioxide removal in patients suffering from respiratory failure. Positive pressure ventilation (PPV) through the use of mechanical ventilators has been a therapy in patients suffering from respiratory failure. Major indications for the initiation of positive pressure ventilation (PPV) include hypoxemia refractory to conventional therapy and ventilator failure but it is an invasive and time consuming process, and consumes tremendous resources, emotionally and financially. PPV is usually used in emergency and critical care situations. For long-term ventilation in veterinary medicine, veterinarians prefer ICU ventilators. But patients that come with imminent respiratory failure need to be managed quickly. In such cases, veterinary respiratory ventilators are used. Veterinary respiratory ventilators have a variety of applications in head trauma, obesity, debilitated patients, or during surgery. Anesthetic ventilators can deliver breathing assistance to a patient by pressure cycled-delivers, volume cycled-delivers, and time cycled-breaths in a given specific interval of time. Veterinary respiratory ventilators are used for stabilization of the ABCDs (i.e., airway, breathing, circulation, and dysfunction).
