1. Skin temperatureHeart rate

Tasks

1. Blood pressure

2. Respiration as a control to verify the timing of signals 1 and 2Rest

3. Breathing awareness meditation

Analysis steps Acqknowledge

1. Copy raw data into shared folder → copy to local folder

2. Separate valsalva, inspiratory loading and breath hold rest and meditation blocks into separate files

3. Create focus areas for each task/file

4. Run cardiac signal detection

   1. Visually inspect markers on signal

   2. Manually correct markers

   3. Export excel spreadsheet with all ECG intervals: will only use HR and R-R interval

5. Run blood pressure signal detection and manually correct markers

   1. Export excel spreadsheet with blood pressure data: systolic and diastolic

6. Run respiration peak detection and manually correct markers

   1. Find cycle inspiration-to-inspiration to get breath-to-breath breathing rate

   2. Find cycle inspiration-to-expiration for inspiration time

   3. Find cycle expiration-to-inspiration for expiration time

7. skin temperature analysis: excel spreadsheet

8. Run tonic EDA analysis

Excel calculations

Create excel spreadsheet for each task and subject that contains:

1. HR

2. R-R

3. Systolic blood pressure

4. Diastolic blood pressure

5. Breathing rate

6. Inspiration time

7. Expiration timeTemperature

8. Skin conductance

Matlab analysis
