In a crude oil contract, a one-cent move is equal to $10. When determining NYMEX's crude oil profit and loss figures, you calculate the difference between the contract price and the exit price, and then multiply the result by $10.
The hypothesis is that strict fluid restriction leads to a larger increase in plasma sodium than standard treatment in patients with decompensated heart failure associated with hyponatremia. A secondary hypothesis is that the neurohormonal change is greater in patients treated with strict fluid restriction versus standard treatment.
Hyponatremia is an electrolyte disturbance characterized by a sodium concentration in the plasma below 135 mmol/L. At lower levels, overhydration (water intoxication), an urgently dangerous condition, may result. Severe hyponatremia can cause an osmotic transfer of water from the plasma into the brain cells. Most body cells can expand as they take on water, but brain cells are confined in the skull. The following symptoms may therefore begin to be experienced as brain cells take on water:
