how to calculate tube feeding for nursing
Other medical conditions require a large amount of daily calories that patients cannot get through oral intake.
There are many different types of formulas for tube feeding, but calculating the number of calories a patient needs can help a person understand how much formula they should get through tube feeding.
Once a person understands how many formulas he gets within 24 hours, he can calculate the feeding rate.
Calculate the energy needs of the patient.
Record the weight of the patient in pounds.
Convert the patient\'s weight into kg.
To do this, divide the weight of the patient by 2 lbs. 2 pounds/kg.
For example, a patient weighing 110.
2 lbs/light activity: BMR x 1. 375;
Moderate activity: BMR x 1. 55;
Very active: BMR x 1. 725.
Calculate the feeding rate of the tube.
Most formulas offer 1 kilocalories/ml or 2 kilocalories/ml.
Most of the schemes are in 250 ml cans.
If a person needs 1,500 kilocalories from the tube feed, they need 4 cans or 1,000 2 ml
0 kcal/mL formula.
In order to determine the feeding rate, divide the total number of feeding tubes by 24 hours.
Rate is 42 ml/hr.
Some people may inject total volume in less time.
If this person wants to inject volume within 8 hours, the speed will be 125 ml/hr.
Calculate the water demand and calculate the additional water demand.
This can be calculated by multiplying the patient\'s weight by 35 kg/kg.
For example, 50 kg x 35 ml/kg = 1,750 ml of the fluid.
Calculate additional water requirements.
The person who is feeding in the tube needs extra water to prevent dehydration.
Determine the percentage of free water provided by the formula.
This information can be found on the formula, or the dietitian can be contacted.
For example, a woman weighing 50 kg kilograms is required to feed the tube at a speed of 55 ml/hour, requiring 1,800 ml of water.
According to the label on the tube feed is 82% free water.
Multiply the volume of the tube feeding formula given every 24 hours by the percentage of free water content.
For example, 55 ml/hr x 24 hours x.
82 = 1082 ml of water, provided in the formula.
Subtract the free water provided by the formula from the calculated total free water demand.
This is equal to the amount of free water remaining.
For example, 1,800 ml of liquid 1,082 ml of water = 718 ml.
Divide the remaining free water volume by 3 or 4 boluses per day.
For example, 718 ml/month = 239 ml of liquid per month.
