            1. Early Stage Compensation
              1. Decreased CO
                1. Decreased BP
                  1. RAAS stimulation
                    1. Increased Na+ reabsorption
                      1. Increased blood Osm
                        1. Increased ADH
                          1. Increased H2O absorption
                          2. Thirst
                            1. Increased fluid intake
                              1. Increased BV
                                  1. Increased blood entering the heart per beat
                                    1. Heart wall stretches
                          3. Increased Angiotensin II
                            1. Arterial vasoconstriction
