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 generally defined as a serum sodium level of less than 135 mmol/L and is considered severe when the level is below 120 mmol/L. The cause of hyponatremia is typically classified by a person's fluid status into low volume, normal volume, and high volume.
