ABSTRACT Background In veterinary medicine, high‐flow nasal cannula oxygen therapy (HFNT) has gained popularity in managing hypoxemic respiratory failure, bridging the gap between conventional and mechanical ventilation. The SpO 2 :FiO (SF) ratio could be useful assessing oxygenation impairment dogs undergoing HFNT. current study aimed to determine whether SF correlates with PaO (PF) Key Findings A total of 30 data pairs concurrent measurements were identified from 19 treated HFNT two university teaching hospitals. PF ratios measured when fell 74 129 mm Hg. median 186 (interquartile range: 97–243) 168 108–297), respectively. strongly correlated (rho = 0.86 [95% confidence interval: 0.73–0.93], P < 0.001, weighted r 0.89 0.74–0.96]). Significance Preliminary results suggest a statistically significant positive correlation This provides that can used calculate appropriate sample sizes for subsequent studies investigating specific corresponding as criteria hypoxemia.
