Dialyzer: High-Flux Hemodialyzer

Description

The Dialyzer data frame has 140 rows and 5 columns.

Format

This data frame contains the following columns:

Subject

a factor with levels A to T

QB

a factor with levels 200 and 300 giving the bovine blood flow rate (dL/min).

pressure

the transmembrane pressure (dmHg).

rate

the hemodialyzer ultrafiltration rate (mL/hr).

index

index of observation within subject---1 through 7.

Details

Vonesh and Carter (1992) describe data measured on high-flux hemodialyzers to assess their in vivo ultrafiltration characteristics. The ultrafiltration rates (in mL/hr) of 20 high-flux dialyzers were measured at seven different transmembrane pressures (in dmHg). The in vitro evaluation of the dialyzers used bovine blood at flow rates of either 200~dl/min or 300~dl/min. The data, are also analyzed in Littell, Milliken, Stroup, and Wolfinger (1996).
