Oxygen Desaturation During Hemodialysis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02501044
Recruitment Status : Completed
First Posted : July 17, 2015
Last Update Posted : July 17, 2015
Information provided by (Responsible Party):
Renal Research Institute

Brief Summary:

Hemodialysis patients may experience drops in blood oxygen saturation during the hemodialysis treatment, which may lead to hypoxia in the tissues.

The investigators hypothesize that:

  1. The cumulative number, severity, or other characteristics of such deoxygenation episodes may be a predictor of adverse outcomes in hemodialysis patients.
  2. There may be demographic, anthropometric, clinical, treatment prescription, lab analytical, and other parameters that correlate with the number and severity of deoxygenation episodes and, therefore, may be used for risk stratification. Further, some of these parameters may be modifiable.

Hemodialysis Patients

Primary Outcome Measures :
  1. Cumulative number of deoxygenation episodes [ Time Frame: Up to 36 months ]
    Crit-Line III monitor recordings (which contain oxygen saturation data) will be extracted from the RRI database and the cumulative number of deoxygenation episodes will be analyzed.
