Abstract
Intermittent positive pressure ventilation (IPPV) settings were evaluated during experimental inhalation anesthesia in horses. Minute volume elavated with the increases in respiratory rate and end-inspiratory airway pressure. Among the settings in this study, 20-25 cmH2O end-inspiratory airway pressure and 6-8 breaths/min of respiration rate maintained the most satisfactory values in arterial blood pH, blood gases tensions and tidal volume. The above IPPV settings were used in clinical cases following spontaneous ventilation anesthesia (30 min) and respiration depression was improved.
