COLLOCATIONS FROM CORPUS
■ NOUN
chloride
▪
Inorganic salts such as sodium chloride , potassium chloride and potassium iodide form eutectic mixtures with water.
▪
In the future, many salty foods will use mixtures of potassium chloride to redress the balance.
▪
In his car-it looks like a Passat-he has cylinders of carbon monoxide and bottles of potassium chloride .
▪
He drives around Michigan with bottles of potassium chloride and cylinders of carbon monoxide.
concentration
▪
Proton concentrations for each sample were then calculated from the hydrogen ion activity and the combined sodium and potassium concentrations.
▪
This is effective not because it lowers serum potassium concentration but because it directly antagonizes the membrane depolarizing effect of hyperkalemia.
▪
The electrocardiogram provides a graphic indication of the membrane effects of altered potassium concentrations .
▪
HYPOKALEMlA A low plasma potassium concentration is not always accompanied by a deficit in total body potassium.
▪
Occasionally, a substantially increased platelet or white cell count may lead to apparent increases in plasma potassium concentration .
▪
What is actually observed in this Circumstance is an increase in serum potassium concentration .
▪
As a result, extracellular potassium concentration decreases.
▪
This causes an increase in extracellular potassium concentration .
excretion
▪
Sodium Sodium delivery to the distal tubule is necessary for adequate potassium excretion .
▪
Should the supply of sodium ions presented to the distal exchange sites decrease, potassium excretion decreases also.
▪
Acidemia tends to decrease potassium excretion , and alkalemia tends to increase potassium excretion.
level
▪
The medical experts found potassium levels were particularly high in some children.
▪
She suffered from dehydration, her potassium levels were dangerously low, and she had lost 15 pounds.
▪
The serum potassium level is sometimes helpful in determining acid-base status.
▪
However, aldosterone is also regulated by sodium and potassium levels and more importantly by the renin-angiotensin system.
▪
The serum potassium level may be of assistance in suggesting whether the patient is acidemia or alkalemia, as described above.
▪
For example, in acidosis from diarrhea, the serum potassium level is often low rather than high.
permanganate
▪
The sergeant sat down, placed his feet into the ice-cold potassium permanganate solution and heaved a euphoric sigh of relief.
▪
Convenient and effective dyes for introducing into water flows include potassium permanganate , gentian violet, and methyl blue.
▪
Some one has suggested I should try potassium permanganate , but what quantities per gallon should I use?
▪
At the same time it is recommended that sufficient potassium permanganate crystals be added to the water to turn it violet.
plasma
▪
HYPOKALEMlA A low plasma potassium concentration is not always accompanied by a deficit in total body potassium.
▪
Occasionally, a substantially increased platelet or white cell count may lead to apparent increases in plasma potassium concentration.
serum
▪
His temperature was 37°C, pulse 84/ min, and serum potassium 3.8 mmol/l.
▪
This is effective not because it lowers serum potassium concentration but because it directly antagonizes the membrane depolarizing effect of hyperkalemia.
▪
The serum potassium level is sometimes helpful in determining acid-base status.
▪
The serum potassium level may be of assistance in suggesting whether the patient is acidemia or alkalemia, as described above.
▪
What is actually observed in this Circumstance is an increase in serum potassium concentration.
▪
For example, in acidosis from diarrhea, the serum potassium level is often low rather than high.
■ VERB
increase
▪
Acidemia tends to decrease potassium excretion, and alkalemia tends to increase potassium excretion.
▪
Additionally, there will be an increased renal excretion of potassium causing a decrease of potassium in the extracellular fluid. 258.
EXAMPLES FROM CORPUS
▪
As is the case for calcium, correction of potassium deficiency may not be possible until the serum magnesium level is normalized.
▪
Diarrhea, due to gastrointestinal disorders, infections, and even laxative abuse, may lead to substantial potassium losses.
▪
Growth failure is also seen in hypokalemic children, particularly those with chronic potassium depletion.
▪
Perception, that is to say, boils down to the passage of sodium, potassium and other ions across semi-permeable membranes.
▪
The electrocardiogram provides a graphic indication of the membrane effects of altered potassium concentrations.
▪
The medical experts found potassium levels were particularly high in some children.
▪
These can be bleached by applying a potassium ferricyanide solution to them.
▪
Unlike sodium, potassium exhibits no renal threshold being excreted into the urine even in K depleted states.
