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.
Most of the water in the body is in the cells. If water moves from the cells to the plasma, it dilutes the plasma, resulting in hyponatremia. Increased oral intake of water or decreased renal clearance of water can dilute the plasma. Antidiuretic hormone (ADH) prevents the clearance of water from the body.
