Right atrial line

The right atrial (RA) line monitors RA pressure and is indicative of right ventricular function, preload and afterload. The RA line enters the right atrium through the right atrial appendage, and always exits the right side of the chest medial to the left atrial line. It is typically a double lumen catheter. The normal right atrial values are 1-7 mmHg.
