Once the damper is released, the line should start flowing freely. Hypertension 2009. Imperial-Perez, F. and McRae, M. (2002). Mitigation of blood loss can be achieved through use of pediatric tubing (smaller volumes), utilization of tubing systems that incorporate a reservoir, and point of care rather than traditional chemical analysis.
acute aortic syndromes, ICH), Need for invasive haemodynamic monitoring (e.g. An arterial waveform is a graph that shows the blood pressure in an artery over time. If the dampered arterial line is not fixed properly, it could lead to serious health complications for the patient. Although arterial cannulation is a generally safe procedure, complications can occur. Site selection is the first consideration for arterial cannulation. Changes in intravascular pressure are transmitted through rigid, fluid-filled tubing that propagates the pressure wave to a transducer. Arterial cannulation: a critical review. A common problem with arterial lines is that they can become underdamped, meaning that blood flow through the line is not consistent. Additionally, this allows for correlation with other measurements of cardiac filling pressures obtained from devices with catheter tips in the great vessels or intracardiac chambers,1 such as central venous pressure measurement and hemodynamic measurements obtained from a pulmonary artery catheter. -Make sure the patient is not over- or under-hydrated.

Ultrasound-guided catheterization of the radial artery: a systemic review and meta-analysis of randomized controlled trials. Common sites which can be used include the radial, brachial and femoral arteries. It is supposed to be an aortic pulse waveform produced by applanation tonometry of the radial artery. However, in recent years, the use of ultrasound guidance for radial catheter placement has increased. Gently remove the dressing making sure to not place any tension on the arterial catheter, Turn the stopcock off to the flush solution. systolic pressure upstroke begins ~60 mseclater in the radial artery thanthe aorta, increased diagnostic blood loss and anemia, vessel damage may lead to stricture and prevent future AV fistula formation for haemodialysis. The most frequent complication of invasive BP monitoring is equipment misuse and misinterpretation, Use aseptic technique to spike bag and prime entire tubing (stopcocks, luer-loks, transducer), Insert IV fluid bag into pressure bag and inflate the pressure bag to 300 mmHg, Insert transducer into the transducer holder, Label IV bag with date and time solution is hung + initials, How often does solution need to be changed?
