What should be monitored to assess respiratory system performance?

To assess respiratory system performance, monitoring behavioral changes and vital signs is crucial as these indicators provide direct insight into the patient's respiratory status. Changes in vital signs like heart rate, respiratory rate, and oxygen saturation can signal how well the respiratory system is functioning. For example, an increase in respiratory rate may indicate respiratory distress or a decreased ability to oxygenate blood effectively.

Behavioral changes, such as increased restlessness or altered levels of consciousness, can also suggest hypoxia or other respiratory issues. Thus, observing these signs helps healthcare providers evaluate the adequacy of oxygen delivery and the general effectiveness of the respiratory system.

In contrast, monitoring skin temperature, mucus presence, or patient mobility offers less direct information regarding respiratory function. Skin temperature may give insights into overall health but does not specifically indicate respiratory performance. The presence of mucus can be relevant; however, it is only one aspect of lung function and does not provide a comprehensive view. Monitoring patient mobility, while important for overall health, does not directly reflect respiratory system performance.
