Abstract

Objective: To evaluate the outcomes of applying high-flow tracheal oxygenation (HFTO) technique via tracheostomy tube at Hanoi Medical University Hospital and describe some complications of this technique. Research Methods: A descriptive study was conducted on 30 tracheostomy patients at Hanoi Medical University Hospital who were indicated for high-flow oxygen therapy through a warming and humidifying device from July 2023 to July 2024. Clinical assessments and blood gas analysis were performed at 7 time points: T0, T1, T2, T3, T4, T5, T6. Results: During the first 24 hours, patients' heart rate and blood pressure were maintained at stable levels. Respiratory rate gradually decreased and remained stable throughout the 24 hours. SpO2 levels increased rapidly within the first 15 minutes and remained stable over the next 24 hours. The patients' PaO2/FiO2 ratio showed a good improvement trend within 24 hours of using HFTO. There was no statistically significant difference between the arterial blood gas values of patients using invasive mechanical ventilation and HFTO. The success rate of this technique was 86,67%, with a failure rate of 13,33%. Notably, no complications due to HFTO were recorded throughout the application process. Conclusion: Clinical indicators and arterial blood gas values of patients remained stable within 24 hours of applying the HFTO technique, with no complications encountered during HFTO therapy.
