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.
In asymptomatic patients, severe hyponatremia (serum sodium < 121 mEq/L; effective osmolality <240 mOsm/kg) can be treated safely with stringent restriction of water intake. In patients with neurologic symptoms(eg, confusion, lethargy, seizures, coma), treatment is more controversial.
