1.   Procedure
      A.  Prepare Physiograph
       1.   Channel I      - EKG
       2.   Channel II     -Respiration
       3.   Channel III    - Blood Pressure

     B.  Blood Pressure (Exp 18)
       1.   Calibrate ESG Coupler
       2.   Record: normal, standing & reclining blood pressures; during Valsalva maneuver (straining against a closed glottis), effect of cold . Do not do the effect of exercise at this time.

   C.  Respiration (Exp 19)
       1.   Attach impedance pneumograph and disc electrodes bellows pneumograph will not be used.
       2.   Record: normal respiratory movements (at .25 cm/sec. only), the effect of asphyxia, hyperventilation, and cord
            facilitation. Omitfandg.

   D.  Integrated Cardiovascular Physiology (Exp. 21)
       1.   Attach impedance pneumograph, EKG channel, and ESG coupler
       2.   Record: normal blood pressure, EKG, and respiratory movements
       3.   Exercise
       4.   Record: recover 1 min., 2 min., 3 min., i min.

II. Report

    Section A
   1.  Title page
   2.  Records
       a.   Effect of posture
            (1) sitting (normal blood pressure)
            (2) standing
            (3) reclining
       b.   Valsalva maneuver - straining against a closed glottis, as in lifting, defecation, or coughing.
       c.   Effect of cold.
    3.Discussion - Include control mechanisms involved in normal blood pressure; the effect of posture on blood pressure; and the effect of the Vaisalva maneuver and cold on blood pressure.

 Section B
       Records
       a.   Normal breathing movements
       b.   Asphyxia
       Discussion - Include the physiological principles involved in normal, quiet breathing; discuss the effect of asphyxia.

   Section C
   1.  Records
       a.   Hyperventilation
       b.   Cord facilitation
   2.  Discussion - Include the physiological principles of each situation.

   Section D
   1.  Records
       a. Normal EKG, breathing movements, and blood pressure
       b. Post-exercise EKG, breathing movements, and blood pressure
   2.  Discussion - Discuss the effects of exercise on each of the three parameters and the physiological principles involved.
