肺部插管過程中供氧裝置運作對醫生病患間氣溶膠流場分佈之影響
Air Flow Analysis Measurement during Intubation
摘要
實驗中建立一簡易版呼吸器模擬人體肺部的呼吸，並使用霧化的混和油作為示蹤氣體（Tracer gas），利用高感度攝影機記錄煙霧被綠光雷射照射後的散射情形，再利用後處理進行分析氣流分布。流場可視化技術良好地呈現整體手術房的大面積流場分佈情況，搭配4種不同的供氧裝置與不同的供氧量及假人呼吸量，模擬感染呼吸道疾病的病人插管前，使用供氧裝置時的氣流分布情況。

In order to understand the spread of droplets and aerosols when different oxygen supply devices are used for intubation therapy, this study uses Particle Image Velocimetry (PIV) technology to analyze the airflow distribution between the medical and the patient. In the experiment, a simple version of the respirator was established to reproduce the breathing of the human lungs. This model used oil to create the smoke as the tracer gas, then a high-sensitivity camera was used to record the scattering light from smoke, which is irradiated by the green laser sheet. In the end, with the post-processing techniques, the airflow distribution is analyzed. On the other hand, flow field visualization can effectively present the flow field distribution of the entire operating room. Experiment with 4 different oxygen supply devices, different oxygen supply and dummy breathing volumes to simulate the air flow distribution of patients with respiratory diseases before intubation.
