Description of columns

Column

Label

1

Pig number (original label)

2

Time minute on day of study (as in 9:00am = 60*9 = 540)

3

Relative to corresponding bleed start

4

State: 1 = stable, 2 = bleed, 0 otherwise (prior to stable period or resuscitating)

5

Bleed number (if its in a stable or bleed epoch), varies from 1-3

6

Valid data (1 = valid, 0 = not valid), in terms of insensible loss below threshold and bleed rate within range

7

Bleed amount (ml), zero unless during the bleed period

8

MAP-aorta

9

EKG heart rate

10

Plethysmography (average)

11

Plethysmography (variance)

12

RR variance determined from EKG

13

EIT belt location (always on thorax and other split between the spleen (2) or intestine plane (3),

14-111

Impedance data from 98 IIVV patterns over the thorax

112-209

Percent each of the 98 impedance values are good over the given minute of data

210-307

Impedance data from 98 IIVV patterns over the spleen or intestine plane

308-405

Percent each of the 98 impedance values are good over the given minute of data

2 of 2

Geometry and IIVV patterns

  • There are 98 impedance patterns for each 16-electrode belt
  • The electrodes are arranged around the pig in the following geometry
  • The IIVV patterns are given in the IIVVused_at_a single_belt.xlsx
