Swan-Ganz catheter

A pulmonary artery (Swan-Ganz) catheter can be used to determine central venous pressure (CVP) pulmonary artery pressure CO and pulmonary artery occlusive pressure (PAOP), an approximate measure of the left ventricular end-diastolic volume and a major determinant of left ventricular preload. 

A pulmonary artery (Swan-Ganz) catheter can be used to determine central venous pressure (CVP) pulmouary artery pressure CO aud pulmonary artery occlusive pressure (PAOP), an approximate measure of the left ventricular eud-diastolic volume aud a major determinaut of left veutricular preload. CO (2.5 to 3 L/min) and mixed venous oxygeu saturatiou (70% to 75%) may be very low in a patient with extensive myocardial damage. Respiratory alkalosis is associated with low partial pressure of O2 (25 to 35 mm Hg) and alkaline pH, but uormal bicarbouate. The first two values are measured by arterial blood gas, which also yields partial pressure of carbon dioxide and arterial oxygen saturation. Circulating arterial oxygen saturation can also be measured by an oximeter, which is a noninvasive method that is fairly accurate and useful at the patient s bedside.

Invasive hemodynamic monitoring usually is performed with a flow-directed pulmonary artery (PA) or Swan-Ganz catheter placed percutaneously through a central vein and advanced through the right side of the heart and into the PA. Inflation of a balloon proximal to the end port allows the catheter to wedge, yielding the PAOP, which estimates the pulmonary venous (left atrial) pressure and, in the absence of intracardiac shunt or mitral valve or pulmonary disease, left ventricular diastolic pressure. Additionally, cardiac output may be measured and systemic vascular resistance (SVR) calculated. Normal values for hemodynamic parameters are listed in Table 14—12. 

Pulmonary artery occlusion pressure—It is usually determined by a balloon-tipped Swan-Ganz catheter that is advanced into a distal branch of the pulmonary artery. Inflation of the balloon at the catheter tip occludes the pulmonary artery and allows measurement of the left atrial pressure which reflects the left ventricular diastolic pressure. Therefore, it is a measure of the left ventricular preload.

In contrast, there are 2 case reports of patients who developed theophylline toxicity (theophylline levels raised to 30 mg/L and 41 mg/L), apparently due to the addition of nifedipine. In one case, the toxicity recurred on rechallenge, and resolved when the theophylline dosage was reduced by 60%. During a Swan Ganz catheter study of patient response to nifedipine for pulmonary hypertension, 2 patients developed serious nifedipine adverse effects, which responded to intravenous aminophylline. ...

Both leads are looped up into the right internal jugular vein (white arrowhead) revealing the mechanism of dislodgment the balloon at the tip of the Swan-Ganz catheter was left inflated while it was pulled back towards the venous sheath.

Many complications are reported particularly with alcohol embolization, such as pulmonary embolus, cardiovascular collapse, neuropathy, skin blisters, radiculopathy, finger numbness, and focal skin necrosis [23, 24]. Arterial line monitoring and Swan-Ganz catheters are recommended for large AVM embolization [24] (Figs. 23.6a-d, 23.7a-d). 

Valuable information is provided by a 12-lead ECG, the insertion of a central venous catheter (for volume status) and in marginal donors a Swan-Ganz catheter (for complete hemodynamic status). 

After arrival at the intensive care unit (ICU) patients are always monitored by arterial and Swan-Ganz catheter measurements. Arterial blood-gas, cardiac output and urine production are measured and the position of the endotracheal tube has to be checked.
