Use a pulse oximeter to measure SpO2 non-invasively.
Place the sensor on a vascular bed (e.g., finger, earlobe) and ensure a proper fit.
Allow the reading to stabilize, usually within a few seconds.
Record the SpO2 level accurately.
Consider factors that can affect oxygen saturation, such as circulation and skin pigmentation.
Pain Assessment
Pain Assessment:
Pain is a subjective experience and varies among individuals.
Use a pain scale (e.g., numerical rating scale, visual analog scale) to assess pain intensity.
Ask the patient to rate their pain on a scale from 0 to 10 or use appropriate pain descriptors.
Assess the location, quality, duration, and aggravating or relieving factors of the pain.
Consider the patient's non-verbal cues, such as facial expressions and body language.
Document the pain assessment findings accurately.
Conclusion
Conclusion:
Accurate measurement of vital signs is crucial for assessing a patient's overall health status and identifying potential abnormalities.
