What does a Swan-Ganz monitor?

Swan-Ganz catheterization (also called right heart catheterization or pulmonary artery catheterization) is the passing of a thin tube (catheter) into the right side of the heart and the arteries leading to the lungs. It is done to monitor the heart’s function and blood flow and pressures in and around the heart.

How does Swan-Ganz measure cardiac output?

Thermodilution cardiac output The thermodilution method involves injecting saline through the proximal port of a Swan-Ganz catheter, with measurement of the area under the curve of temperature change over time in the distal catheter tip.

What are normal Swan-Ganz numbers?

Normal results for this test are: Cardiac index is 2.8 to 4.2 liters per minute per square meter (of body surface area) Pulmonary artery systolic pressure is 17 to 32 millimeters of mercury (mm Hg) Pulmonary artery mean pressure is 9 to 19 mm Hg.

How does Swan-Ganz work?

The procedure involves the insertion of a pulmonary artery catheter (PAC) into the right side of the heart and into the arteries that lead to the lungs. The PAC has a balloon tip. The balloon allows the catheter to be carried by the flow of your blood to the place in your heart where it’ll be used.

What is a normal PA pressure?

Normal pulmonary artery pressure is 8-20 mm Hg at rest. If the pressure in the pulmonary artery is greater than 25 mm Hg at rest or 30 mmHg during physical activity, it is abnormally high and is called pulmonary hypertension.

What are the three uses for a Swan-Ganz catheter?

The procedure is also used to evaluate: heart failure. heart function following a heart attack. shock.

Why would you use a Swan-Ganz catheter?

A Swan-Ganz catheterization is a type of pulmonary artery catheterization procedure. It’s a diagnostic test used to determine whether any hemodynamic, or blood flow-related, abnormalities exist in the heart and lungs. It can be a useful test for people who have recently had heart problems, such as a heart attack.

What is normal pulmonary artery BP?

Normal pulmonary artery systolic pressure at rest is 18 to 25 mm Hg, with a mean pulmonary pressure ranging from 12 to 16 mm Hg. This low pressure is due to the large cross-sectional area of the pulmonary circulation, which results in low resistance.

What is the normal pulmonary BP?

Normal blood pressure in the lungs is 15 -25 mmHg, or about 1/5th the bodies blood pressure. Pulmonary Hypertension results when the blood vessels constrict (tightens). Over time this constriction causes fibrosis (scars) of the vessel and higher pulmonary blood pressure.

How many lumens does a Swan-Ganz have?

5 lumens
The VIP™ model is the standard Swan Ganz™ model in CCTC. It is a 7.5 French catheter with 5 lumens. It must be inserted through an introducer.

What are the four stages of pulmonary hypertension?

About Pulmonary Hypertension

Group 1: Pulmonary Arterial Hypertension (PAH)
Group 2: Pulmonary Hypertension Due to Left Heart Disease.
Group 3: Pulmonary Hypertension Due to Lung Disease.
Group 4: Pulmonary Hypertension Due to Chronic Blood Clots in the Lungs.
Group 5: Pulmonary Hypertension Due to Unknown Causes.

What blood tests show pulmonary hypertension?

Blood Tests

Routine blood tests for pulmonary hypertension patients.
BNP: B-type Natriuretic Peptide in pulmonary hypertension patients.
BMP: Basic Metabolic Panel, a common test for pulmonary hypertension patients.
CMP: Complete Metabolic Panel, a useful test for pulmonary hypertension patients.

What is the normal PA pressure?

What is the gold standard for diagnosing pulmonary hypertension?

Right heart catheterization is the gold standard for diagnosing pulmonary hypertension. Doctors use a catheter to measure the pressure in the heart and lungs. In this procedure, the patient has local numbing medicine.
