Question

Quizplus · Accepted Answer

A vital capacity that is 65% of predicted suggests that the patient may have a pulmonary disease such as emphysema. A normal vital capacity is typically considered to be around 80-120% of predicted. A vital capacity below 80% of predicted is generally considered to indicate respiratory insufficiency or disease. However, it's important to note that vital capacity alone cannot provide a definitive diagnosis, and additional diagnostic tests may be needed to confirm or rule out a potential pulmonary disease.
