Two aspects of laryngeal airflow, constant flow rate (DC) and alternating flow rate (AC), were examined in patients with vocal cord paralysis, acute laryngitis, and vocal cord polyps using the hot wire flowmeter. Vocal cord paralysis was characterized by a large DC with a small AC/DC percentage, and acute laryngitis showed a normal DC in spite of a small AC/DC percentage. No consistent finding was observed for the laryngeal polyp. Simultaneous measurement of both parameters was thought to better define the physiologic correlates of hoarseness in various laryngeal disorders.
使用热线流量计对声带麻痹、急性喉炎和声带息肉患者的喉气流的两个方面，即恒定流速（DC）和交替流速（AC）进行了检查。声带麻痹的特征是DC大，AC/DC百分比小，而急性喉炎尽管AC/DC百分比小，但DC正常。对于喉息肉未观察到一致的结果。同时测量这两个参数被认为能更好地确定各种喉部疾病中声音嘶哑的生理相关性。
