Abnormal narrowing of an artery or arteries. This phase begins with the opening of the aortic valve and corresponds to the left ventricular ejection.
Difference in arterial waveforms according to site of insertion. Arterial blood gas evaluations can be performed without the need for repeated painful needle sticks. The accurate responsive adequately damped art line trace.

This chapter is relevant to Section G7 iii of the 2017 CICM Primary Syllabus which asks the exam candidate to describe the invasive and non-invasive measurement of blood pressure including limitations and potential sources of error.
Mills Nicholas L et al. California institute of abnormal arts. The arterial pressure waveform is a complex wave that represents the summation of a series of mechanical pressure signals of different frequencies.
The a wave may tend to merge with the v wave in the CVP trace and the P wave may be obscured by the T wave in the ECG not apparent in this trace. Arterial catheterization is one of the most frequently performed invasive procedures performed on critically ill patients. Art line waveform damping.
Cunningham R et al. Dicrotic limb Descending limb of the arterial pressure trace as the pressure falls to that of the end diastolic pressure Dicrotic means twice beating meaning that this phase of the arterial pressure pulse should have a second smaller wave known as the dicrotic notch. It is generally considered to be a safe procedure with few serious complications and a major complication rate ranging between 1 and 5.
