Your heart rate, breathing or respiratory rate, blood pressure, and temperature are known as your vital signs. Measuring your vital signs helps your healthcare provider understand how your body is working.
Opioids are often prescribed to relieve the intense pain that accompanies a serious injury or surgical procedure. While opioids can be addictive, they are considered safe and effective for acute pain management if used for the shortest length of time and at the lowest effective dose necessary. A doctor who prescribes opioids for pain management should regularly monitor your pain levels with the goal of safely discontinuing their use when your pain is more manageable (or under control).
