OBJECTIVE: To evaluate arterial blood gas parameters and pulmonary radiography, before and after provision of continuous positive airway pressure (CPAP) via a pediatric helmet in dogs with acute hypoxemic respiratory failure.
DESIGN: Single-center, observational study conducted from 2016 to 2017.
SETTING: University teaching hospital.
ANIMALS: Seventeen dogs presenting with clinical signs compatible with respiratory failure, confirmed by arterial blood gas analyses.
INTERVENTIONS: For each animal arterial blood samples and thoracic radiographs were performed at arrival (T0 ). Hypoxemic dogs (PaO2 <80 mm Hg), without evidence of pneumothorax or pleural effusion, received CPAP ventilation via a pediatric Helmet for at least 1 hour. At the end of CPAP ventilation, a second arterial blood gas analysis was performed at room air (T1 ). The F-shunt was also calculated.
MEASUREMENT AND MAIN RESULTS: Respiratory rate, heart rate and rhythm, mean blood pressure, mucosal membrane color, and rectal temperature were recorded. Tolerance to the helmet was evaluated using a predetermined scoring system. Two dogs were excluded from the study for low tolerance to the helmet. In 15 of 17 dogs, a significant difference between T0 and T1 was noted for PaO2 (60.84 ± 3 mm Hg vs 80.2 ± 5.5 mm Hg), P(A-a)O2 (52.4 ± 4.4 mm Hg vs 35.2 ± 6 mm Hg), PaO2 /FiO2 (289.7 ± 14.3 vs 371 ± 21), and %SO2 (91.3 vs 98.8). In 15 of 17 dogs, the helmet was well tolerated. F-shunt significantly decreased following provision of CPAP (37%; range, 8.4-68% vs 6%; range, -5.6-64.3%).
CONCLUSION: The use of a pediatric helmet appears to be a suitable device for delivery of CPAP in dogs with hypoxemic acute respiratory failure. The device appears to be reasonably tolerated and improved oxygenation in most dogs.
