Because of age-related modifications of the heart, lung, and circulation, several cardiopulmonary parameters present altered normal and reference values with increasing age. Other parameters, for example, arterial blood pressure, change only insignificantly with age. In older age groups it is more difficult to establish reference ranges and values because of the lack of "healthy" subjects. To establish cardiopulmonary parameters, appropriate investigations for the age group, for example, treadmill-ergometer, should be preferred. In judging if a value resulting out of the reference range is to be considered really pathologic, other factors are to be taken into account, such as circadian variations, motivation, associated pathologies as well as the actual physical and psychological conditions, when we are dealing with older subjects or patients.
由于心脏、肺和循环系统随年龄增长而发生变化，一些心肺参数的正常和参考值会随着年龄的增加而改变。其他参数，例如动脉血压，随年龄变化不明显。在老年人群中，由于缺乏“健康”受试者，更难确定参考范围和值。为了确定心肺参数，应优先选择适合该年龄组的检查方法，例如跑步机功率计。在判断超出参考范围的值是否应被视为真正的病理性值时，当我们面对老年受试者或患者时，还应考虑其他因素，如昼夜变化、动机、相关疾病以及实际的身体和心理状况。
