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.
The normal MCH level is between 26 and 33 picograms (one trillionth of a gram) of. hemoglobin per red blood cell. A gram is a very small unit of weight (you would need. 453.359237 grams just to get one pound).
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.
