% 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 I:
Directory: cgomez-1pl/
Placement: Single plane 16 electrodes aligned with the fifth rib directly below the nipple. Electrode 1 is in the centre of the sternum. The other electrodes are labelled moving towards the subject's right side so that electrode 5 in under the right armpit, electrode 9 on the spine and electrode 13 under the left armpit. 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: 62 bpm
Data file: vivo150905_t1_001.get
Note: Measurement begins when lungs are at functional residual capacity.

2. Total Lung Capacity - Residual Capacity (TLC-RC)
Heart rate: 62 bpm
Data file: vivo150905_t1_002.get
Note: Measurement begins when lungs are at residual capacity.

3. Paradoxial Breathing
Heart rate: 62 bpm
Data file: vivo150905_t1_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.

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: 92 bpm
Data file: vivo150905_t1_004.get
Note: Measurement begins when lungs are at functional residual capacity.

5. TLC-RC
Heart rate: 90 bpm
Data file: vivo150905_t1_005.get
Note: Measurement begins when lungs are at residual capacity.

6. Paradoxial Breathing
Heart rate: 84 bpm
Data file: vivo150905_t1_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.
