Non-Invasive vs. Arterial Blood Pressure Monitoring
Non-invasive blood pressure monitoring often fails to provide accurate readings when compared to arterial pressure monitoring in critical pre-hospital scenarios. A study involving Thames Valley Air Ambulance demonstrated that only about 50% of the time did non-invasive measurements align within a 20 mmHg range of arterial line readings, particularly during significant hypertension or hypotension. This inconsistency underscores the importance of arterial lines for accurate blood pressure readings, which are crucial for managing trauma and resuscitation targets. Therefore, if possible, clinicians should prioritize arterial line placement in severely ill patients to ensure reliable blood pressure monitoring.
