Why is it important to monitor a patient's physical signs during oxygen therapy?

Monitoring a patient's physical signs during oxygen therapy is crucial for several reasons. It allows healthcare providers to evaluate the effectiveness of the treatment, ensuring that the oxygen is adequately improving the patient's condition, such as alleviating symptoms of hypoxia or enhancing overall respiratory function. Furthermore, monitoring can help detect any potential complications that may arise from oxygen therapy, such as oxygen toxicity or respiratory depression. By frequently assessing the patient's vital signs and any changes in their clinical status, healthcare providers can make timely adjustments to the therapy, leading to better patient outcomes and overall safety during treatment.
