ARTERIAL BP MONITORING
Indirect methods
Traditional method of cuff and mercury
manometer (Auscultation from the Latin for
listening)
NIBP machine or oscillometry
Non-Invasive Blood Pressure
Direct methods
Intra-arterial catheter / transducer system
Arterial pressure monitoring is a form
of invasive blood pressure monitoring
and is done through the cannulation of
a peripheral artery
. This form of
a peripheral artery
. This form of
monitoring is commonly utilized in the
management of critically ill and
perioperativepatients.
blood vessels become inflamed, swell and can blood vessels become inflamed, swell and can
become blocked with blood clots (thrombi).
The size of the arterial cannula
determines the maximum flow
rate. The15 Fr arterial
cannula
can support flow rate
cannula
can support flow rate
up to 3.5 L/min, whereas the
19 Fr arterial cannulacan
achieve flow up to 5 L/min.
TEGADERM COVER
Arterial catheterization is a procedure
that is common to the intensive care
and the operating room settings. It
involvesplacement of a catheter into
the lumen of an artery to provide at the lumen of an artery to provide at minimum a continuous display blood
pressure with access to frequent
arterial blood sampling.
PROCEDURE
。 Palpate the artery with your
(other) non-dominant hand
・ Use the large needle to
advance through the skin a
a 30 degree angle.
When the artery is entered,
a pulsatile flow of blood
will be seen
Dampened: wide, flattened tracing
・ Dampening occurs due to:
air bubbles
overly compliant, distensible tubing
catheter kinks nodus
clots
low flush bag pressure or no fluid in the flush bag
Improper scaling
Severe hypotension if everything else is ruled out
