How many mEq of potassium is needed to increase serum potassium?
Every 10 mEq of potassium increased serum potassium 0.13 mEq/L. Similar dose responses were seen whether IV or PO potassium was administered. This study supports the common practice of administering 10 mEq of potassium for every 0.1 mEq/L desired increase in serum potassium.
What is the normal range of potassium in serum?

How much does potassium increase with dose of potassium?
Specifically, intravenous and oral potassium administration caused a mean 0.14 and 0.12 mEq/L increase in serum potassium level per 10 mEq administered, respectively. There is no data to suggest that the degree of baseline hypokalemia will exponentially increase the amount of repletion necessary.
How many mEq of KCl do you infuse for potassium?
If central line present and continuous cardiac monitoring, infuse at 20 mEq/hr (max = 40 mEq/hr); If peripheral access only, infuse at 10 mEq/hr. Serum potassium may be expected to increase by ~0.25 mEq/L for each 20 mEq IV KCl infused.

-Rule of thumb in patients with normal renal function: every 10 mEq KCL given will raise the serum potassium level by 0.1 mmol/dL. -PO is the best way to replace potassium if the patient can take PO. -10mEq/hr is the recommended rate for giving KCL peripherally. -If you want to give it faster than 10mEq/hr,
How much potassium should be in an infusion pump?
Use of an infusion pump is preferred to prevent overly rapid potassium administration in any intravenous container with more than 40 meq of potassium or if the desired rate of potassium administration is more than 10 meq/hour.
How much potassium is in a 1000 ml container?
In any 1000 mL -sized container of appropriate non-dextrose fluid, we suggest a maximum of 60 meq of potassium
How is potassium given?
Potassium can be given intravenously via a peripheral or a large central vein. To decrease the risk of inadvertent administration of a large absolute amount of potassium, we suggest the following maximum amounts of potassium that should be added to each particular sized infusion container:
What is the maximum meq/hour for hypokalemia?
However, initial rates as high as 40 meq/hour have been used for life-threatening hypokalemia. Rates above 20 meq/hour are highly irritating to peripheral veins. Such high rates should be infused into a large central vein or into multiple peripheral veins.
What causes excessive renal loss?
The most common cause of excessive renal loss is the use of diuretic agents, especially for the treatment of hypertension. Some forms of chronic renal disease and metabolic disturbances (e.g., diabetic acidosis) can also lead to severe potassium loss.
How many mEq does 15 mmol of KPO4 give?
Giving 15 mmol of KPO4 will give 13.2 mEq of K. Factor that in when repleting K.
Can ESRD patients replete phos?
Be mindful of repleting phos. Patients with ESRD on HD and urine output should likely not replete without a renal consult.
How much potassium is needed for each 0.13 mEq/L?
10 mEq of potassium (IV/ oral) is required for each 0.13 mEq/L (mean value for oral and IV). decline in serum [K+] from the target level.
Where is potassium found in the body?
Potassium is the major intracellular cation with 98% of the total body potassium is in the intracellular compartment and only 2% located extracellularly (plasma). The serum potassium level is a measure of the 2% that is present in the extracellular space.
What are the consequences of hypokalemia?
Severe consequences of hypokalemia include cardiac arrhythmias, rhabdomyolysis, and muscle weakness that leads to respiratory depression or ileus. Chronic hypokalemia can cause increased ammoniagenesis, urinary concentration defects, polyuria, hypertension, acid base disorders, and hyperglycemia.
Does BMI affect potassium levels?
The patient's BMI has little effect when determining the amount of potassium required to reach a target level. Conversely, renal disease can profoundly impact the amount of potassium required.
Does potassium drop in extracellular space?
It takes a significant loss in potassium stores to see a drop in serum potassium level (i.e., the extracellular space) due to this large amount of potassium in the intracellular space that helps to compensate for any loss.
Does hypokalemia increase repletion?
There is no data to suggest that the degree of baseline hypokalemia will exponentially increase the amount of repletion necessary. Therefore, the lack of representation of patients with baseline moderate or severe hypokalemia is not thought to be a limitation to allowing the results of the study to be applied to patients with all degrees of hypokalemia.
