Normative trachea dimensions and aerodynamic information during development was collected to establish clinical benchmarks and showed that airway development seems to outpace respiratory demands. Infants and toddlers' trachea exhibit higher aerodynamic stress that significantly decreases by teenage years. This implies large airway pathology in younger children may have a more substantial clinical impact.
收集了发育过程中的正常气管尺寸和空气动力学信息，以建立临床基准，并表明气道发育似乎超过了呼吸需求。婴儿和幼儿的气管表现出更高的空气动力学压力，这种压力在青少年时期显著降低。这意味着年幼儿童的大气道疾病可能具有更大的临床影响。
