Abdominal Compression Elastic Support (ACES)

The ACES will be used for HD patients who have had IDH episodes in the last month. For these patients, the ACES will impose a compression pressure of 15 mmHg to compress the abdominal section over the last three hours of the HD treatment. This action can increase venous return and hence cardiac output to improve the cardiovascular function of the patient. In this way, the IDH episode may be prevented or reduced in severity. This use is much less cumbersome over the use of IAB in dealing with PDOH. We perform this trial study to show the use ACES is more effective than the Trendelenburg maneuver or the infusion of isotonic saline, for example.
