of the Week:
- Every other arterial pressure wave has a decreased systolic blood pressure.
- The R - R interval on the ECG and systolic - systolic interval on the arterial line are regular, ruling out arrhythmia as the cause for the fluctuating systolic pressure.
- Considered a significant difference if there is a 20 mmHg difference between alternating systolic pressures.
Generally caused by severe left ventricular failure or pericardial effusion.
in a pulmonary artery tracing can indicate severe right ventricular failure.
