Cardioversion vs Defibrillation Both cardioversion and defibrillation involve delivering electrical energy to the chest to alter the heartbeat. Both are contraindicated in digoxin and catecholamine induced dysrhythmias.
Normal Range for MCHC: 32-36 grams/deciliter in adults. SI units: 334-355 gram/liter. A low MCHC means that there is less hemoglobin in each red cell regardless of the size of the red cell, known as hypochromia. It is seen in iron deficiency anemia and thalassemia.
It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL, or between 19.9 and 22.3 mmol/L. It is thus a mass or molar concentration. Still, many instances measure MCHC in percentage (%), as if it were a mass fraction (m Hb / m RBC). Numerically, however, the MCHC in g/dL and the mass fraction of hemoglobin in red blood cells in % are identical, assuming a RBC density of 1g/mL and negligible hemoglobin in plasma.
