Final answer:
An actual TLC higher than predicted may suggest better lung health or an error in prediction; RV is likely unchanged.
Step-by-step explanation:
If the predicted TLC (Total Lung Capacity) is 3.6 and the actual measurement is 4.2, it indicates that the person's lung capacity is greater than what was predicted. This could be due to a variety of factors such as better lung health or an error in the predicted value. As for the RV (Residual Volume), it is likely to be unaffected by the change in TLC unless there has been a change in lung compliance or airway resistance. Typically, RV would be expected to remain within its normal predicted range unless the person has an underlying condition affecting their lungs.
In this question, you are comparing the predicted TLC (Total Lung Capacity) with the actual TLC. The predicted TLC is 3.6 and the actual is 4.2. This means that the actual TLC value is higher than the predicted value.
In terms of RV (Residual Volume), we would need more information to predict its value. The RV represents the volume of air that remains in the lungs after a person exhales as much as possible. It is not directly related to the TLC measurement. Factors such as age, height, and lung disease can influence RV.
