The overall objective of this preliminary investigation was to determine whether breathing patterns of patients with chronic obstructive pulmonary disease could be altered by training patients to voluntarily change their breathing, using techniques of biofeedback training. The specific aims were (1) to develop a method of monitoring respiratory rate and tidal volume with a device that was both accurate and usable without discomfort or inconvenience to the patient; (2) to use the method with patients having chronic obstructive pulmonary disease to determine whether respiratory rate could be slowed by voluntary controls; and (3) to determine whether patients who could slow their breathing rate would increase their tidal volume and demonstrate other respiratory changes.
这项初步调查的总体目标是确定慢性阻塞性肺疾病患者的呼吸模式是否可以通过使用生物反馈训练技术训练患者自愿改变呼吸来改变。具体目标是：（1）开发一种使用对患者既准确又使用时不会造成不适或不便的设备来监测呼吸频率和潮气量的方法；（2）将该方法用于慢性阻塞性肺疾病患者，以确定呼吸频率是否可以通过自主控制减慢；（3）确定能够减慢呼吸频率的患者是否会增加潮气量并表现出其他呼吸变化。
