% THE EXPERIMENT
% ****************************
Subject: Camille Gomez-Laberge
Age: 25
Status: Healthy
Experimenter: Li Peng Xie
Date Collected: September 15, 2005
Locale: Research laboratory
Equipment: EIT Viasys / University of Gottingen
Electrodes: 17 EKG Blue Sensor Ag/Ag-Cl electrodes (16 + reference)
Skin Preparation: Rubbing alcohol
Measurement Procedure: All measurements are taken while the subject is supine. Ambient temperature in room is 25 degrees Celcius. Details for each part of the experiment follow.

PART II:
Directory: cgomez-2pl/
Placement: Two planes of 8 electrodes each. The upper plane is vertically aligned with the fifth (5) rib directly below the nipple and the lower plane with the seventh (7) rib directly below the nipple. Electrode 1 is on the upper plane in the centre of the sternum. Electrode 2 is on the lower plane but shifted to the right by half the inter-electrode distance on the upper plane. The other electrodes are labelled in a zig-zag pattern, moving towards the subject's right side. The reference electrode is placed on the right side of the subject's waist line.

Subject is rested - in normal state

1. Tidal breathing
Heart rate: 58 bpm
Data file: vivo150905_t2_001.get
Note: Measurement begins when lungs are at functional residual capacity.

2. Total Lung Capacity - Residual Capacity (TLC-RC)
Heart rate: 64 bpm
Data file: vivo150905_t2_002.get
Note: Measurement begins when lungs are at residual capacity.

3. Paradoxial Breathing
Heart rate: 60 bpm
Data file: vivo150905_t2_003.get
Note: Subject is holding breath and transfering air across thorax by expanding the rib cage and then expanding the abdomen. This is repeated every 5 seconds for the duration of the sample. Measurement begins with abdomen expanded.

Subject induces stress on the cardiovascular system by lower-body excercise (e.g running, climbing stairs).
Subject ran until heartrate exceeded 90 bpm (approx. 6 minutes in this case).
NOTE: The electrodes are not removed during excercise.

4. Tidal breathing
Heart rate: 102 bpm
Data file: vivo150905_t2_004.get
Note: Measurement begins when lungs are at functional residual capacity.

5. TLC-RC
Heart rate: 96 bpm
Data file: vivo150905_t2_005.get
Note: Measurement begins when lungs are at residual capacity.

6. Paradoxial Breathing
Heart rate: 76 bpm
Data file: vivo150905_t2_006.get
Note: Subject is holding breath and transfering air across thorax by expanding the rib cage and then expanding the abdomen. This is repeated every 5 seconds for the duration of the sample. Measurement begins with abdomen expanded.
