| Question | Answer |
|---|---|
| ABG - pH | 7.35 to 7.45 |
| ABG - PaO2 | 80 to 100 mm Hg |
| ABG - SaO2 | 93% to 96% |
| ABG - PaCO2 | 35 to 45 mm Hg |
| ABG - HCO3 | 22 to 26 |
| Mixed Venous Gases - SvO2 | 60% to 75% low SvO2 means high consumption and less oxygen; high SvO2 means low consumption and high oxygen |
| Glucose (fasting) | 70 to 110 mg/dL |
| Blood urea nutrogen (BUN) | 5 to 25 mg/dL |
| Creatinine | 0.5 to 1.5 mg/dL |
| Sodium | 135 to 145 mEq/L |
| Potassium | 3.5 to 5.3 mEq/L |
| Magnesium | 1.5 to 2.5 mEq/L |
| Lactate - Arterial blood | 0.5 to 2.0 mmol/L |
| Lactate - Venouse blood | 0.5 to 1.5 mmol/L |
| Total Cholesterol | < 200 mg/dL |
| LDL | 60 to 160 mg/dL |
| HDL | 29 to 77 mg/dL |
| Albumin | 3.5 to 5.0 g/dL |
| Total protein | 6.0 to 8.0 g/dL |
| ALT | 10 to 35 units/L |

| Bilirubin Direct | 0.1 to 1.2 mg/dL |
| PT | 10 10 13 secs |
| PTT | 60 to 70 secs |
| APTT | 20 to 35 secs |
| A1C | 2% to 5% |
| Hematocrit - Male | 40% to 54% ; high Hct means less more RBC than other fluid, so there is fluid deficit. |
| Hematocrit - Female | 36% to 46% ; high Hct means less more RBC than other fluid, so there is fluid deficit. |
| Hemoglobin - Male | 13.5 to 17 g/dL |
| Hemoglobin - Female | 12 to 15 g/dL |
| Platelet count | 150,000 to 400,000 ul |
| WBC | 4,500 TO 10,000 |
| Neutrophils (total) | 50% to 70% or 2,500 to 7,000 /ul |
| Eosinophils | 1% to 3% or 100 to 300 /ul |
| Lymphocytes | 25% to 35% or 1,700 to 3,500/ul |
| Urine - Specific Gravity | 1.005 to 1.030 |
| Blood pressure | 120/80 |
| MAP for adequate perfusion | > 60 |
| MAP Formulat | [ systolic + (diastolic *2) ] / 3 |
| MAP Normal range | 70 to 90 mmHg |
| CO | 4 to 8 L/min |
| CO formula | SV * HR |

| PA pressure (Left ventricular) | 15-25 / 8-15 mm Hg |
| PAWP (left atrial pressure) | 8 to 12 mmHg |
| Heart ejection fraction | 55% to 75% |
| Cerebral perfusion Pressure (CPP) | 60 to 100 ; according to the Society of Critical Care Medicine (SCCM) |
| Intracranial Pressure (ICP) | 5 to 15 mm Hg |
| Intracranial volume | volume of brain tissue + blood + + CSF + any abnormal lesion (if volume of one component goes up, the other component either be compressed or goes down because brain can not expand to accomodate extra pressure.) |
| ICP of patient in Supine position | 7 to 15 mm Hg |
