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 defined as a serum sodium concentration lower than 136 mmol/L. It can result from a particular laboratory technique or from improper blood collection, excessively high water intake, or, most commonly, an inability of the kidneys to excrete free water (see later, âPathophysiology and Natural Historyâ).
