Use of prototype bi‐nasal prongs for noninvasive ventilation in foals
Abstract Background Noninvasive ventilation (NIV) provides effective respiratory support in foals, but face masks are poorly tolerated and associated with hypercapnia. Bi‐nasal prongs might be a more effective device interface in foals. Objectives To compare bi‐nasal prongs and masks for NIV in foal...

| description | Abstract Background Noninvasive ventilation (NIV) provides effective respiratory support in foals, but face masks are poorly tolerated and associated with hypercapnia. Bi‐nasal prongs might be a more effective device interface in foals. Objectives To compare bi‐nasal prongs and masks for NIV in foals with pharmacologically induced respiratory insufficiency. Animals Six healthy foals. Methods In a randomized cross‐over study, sedated foals received NIV delivered by mask or bi‐nasal prongs, with the treatment repeated using the alternative device interface after a 3‐day rest period. After periods of spontaneous ventilation through the allocated interface, with and without supplementary O2 (T2‐T3), foals were subject to 10‐minute treatment periods of NIV at different pressure support (5 or 10 cmH2O) and end‐expiratory pressure settings (5 or 10 cmH2O), with and without supplementary O2 (T4‐T7). Vital signs, arterial blood gases, spirometry, and gas exchange data were measured in the final 2 minutes of each treatment window. Results Bi‐nasal prongs were well tolerated and required less manual positioning or monitoring compared to the mask. Partial pressure of carbon dioxide did not increase during NIV with bi‐nasal prongs and was lower than observed with masks (mean difference, 8.2 mmHg [95% confidence interval, 4.1‐12.2 mmHg] at T6). Oxygenation and respiratory mechanics were improved in all foals and not different between device interfaces. Conclusions and Clinical Importance Nasal prongs were well tolerated, had similar effects on respiratory function, and appeared to ameliorate hypercapnia observed previously during NIV in foals. |
