Original publication title: High flow oxygen therapy versus conventional oxygen therapy in dogs and cats undergoing bronchoscopy and bronchoalveolar lavage: a pilot study.
Plain-English summary
A group of dogs and cats undergoing bronchoscopy (a procedure to look inside the airways) received either high flow oxygen therapy (HFOT) or conventional oxygen therapy (COT) during the procedure. The study found that HFOT was safe and did not cause any complications, and it helped keep oxygen levels higher in the pets compared to COT. None of the pets receiving HFOT experienced severe drops in oxygen levels, while some in the COT group did. Overall, HFOT may be a better option for pets needing this type of procedure, as it seems to reduce the risk of low oxygen levels.

Abstract
OBJECTIVES: To evaluate the safety and feasibility of high flow oxygen therapy (HFOT), and to record SpOand desaturation episodes in dogs and cats receiving HFOT or conventional oxygen therapy (COT) during bronchoscopy ± bronchoalveolar lavage (BAL). MATERIALS AND METHODS: Dogs and cats undergoing bronchoscopy ± BAL between January and May 2023 were included in the study. Patients were randomly allocated to two groups: HFOT (HFOT group; two cats and four dogs) and COT (COT group; one cat and five dogs). HFOT and COT were started at the beginning of the bronchoscopy. HFOT was delivered with a gas flow rate of 1 L/kg/min at an FiOof 100% and a temperature of 34°C (pediatric mode) or 37°C (adult mode). COT was delivered through the working channel of the bronchoscope at a rate of 1.5 L/min. The safety and feasibility of HFOT were assessed, and peripheral oxygen saturation (SpO) was measured by pulse oximetry every 30 s throughout the procedure. MEASUREMENTS AND MAIN RESULTS: HFOT was feasible and safe in both dogs and cats with no complications reported. While there was no significant difference in the number of desaturation episodes (SpO < 94%) between the two groups, none of the patients in the HFOT group experienced severe desaturation (SpO < 90%). In contrast, two patients in the COT group had an SpO < 90%. Mean SpOwas significantly higher in the HFOT group compared to the COT group at T0 (98% ± 2% vs. 94 ± 2%), T0.5 (98% ± 2% vs. 94% ± 3%) and T1 (98% ± 2% vs. 94% ± 4%). CONCLUSION: To the authors' knowledge, this is the largest study conducted to date using HFOT during bronchoscopy in dogs and cats. Our results suggest that HFOT is feasible and safe during bronchoscopy ± BAL. Furthermore, HFOT may reduce the risk of desaturation episodes in dogs and cats undergoing bronchoscopy and BAL.
