Invasive Arterial Blood Pressure Monitoring

Invasive arterial blood pressure monitoring provides direct, continuous, beat-to-beat pressure measurement and waveform analysis. Distorted invasive arterial pressure readings can lead to harmful clinical decisions. Underestimated blood pressure caused by partial occlusion or kinking can prompt unnecessary fluid or vasopressor treatment. Invasive monitoring is especially important when blood pressure changes rapidly or accurate vasoactive drug titration is needed. Invasive arterial monitoring can be the only feasible continuous circulatory assessment method in some patients with severe obesity or limb disability.
