Mia, a 45 year old woman, was brought to a hospital suffering from chronic emesis for five days brought upon by food poisoning. Her blood pressure is 90/50 mmHg and her rate and depth of breathing are markedly decreased. When asked when did her rate/depth of breathing go down, she reports two days ago. Her lab results show following values:                    Variable                                 Lab Results                       Normal Values                    Blood pH                                     7.40                                   7.35-7.45                  Blood HCO3                            20 mEq/L                            22-26 mEq/L                  Blood PCO2                             60 mm Hg                          35-45 mm Hg   A.
