3. Objectives
1. List the purposes of intake and output
calculations .
2. Mentions the parameters of assessments
before intake and output calculation .
3. Describe the negative and positive balance.
4. Determine who to calculate the intake and
output .

6. The purposes of intake and output calculation
1. Ensure accurate record keeping.
2. Prevent circulatory overloud.
3. Prevent dehydration.
4. Aids in analyzing trends in fluid status.
5. Contributes to accurate assessment record.

7. Why are I/O so Important??
It helps us determine the patient’s
fluid status:
 Are they Hydrated?
 Are they Dehydrated?
 Are they in Fluid Overload?
 Is there an obstruction?

15. What To Look Out For
• Is the patient drinking at least 1500cc a
day (Unless they are on Fluid Restrictions)
• Urinates at least once in an 8 hour shift or
urinate less than 30 cc an hour
(240cc/8hrs)
• Has concentrated or foul-smelling urine
• Has Dry Skin
• Has a temperature above 38⁰C
• Is perspiring excessively
• Has excessive wound drainage

32. Possible Causes of Fluid Excess
• Kidney Disease
• Liver Disease
• Certain Medications : Steroids or a
Sodium Based Medication
• Abnormal Fluid Accumulation in Body
Cavities
• Over infusion of IV Fluids
• Pregnancy

33. The Procedure
The Equipment :
Intake and output chart.

34. Implementations
1. Explain the purpose and procedures for measuring
I&O to the client.
2. Record the volume for all fluids consumed.
3. Make sure that all IV fluids or tube feedings are
being administered at the prescribed rate.

35. Cont Implementations
4. Ensure that the nurse who adds additional IV fluid
containers also records the volume .
5. Keep track of fluid volumes used to irrigate
drainage tubes or flush feeding tubes.
6. Wear gloves.
7. Measure and record the volume of voided urine,
urine collected in a catheter drainage bag, liquid
stool or other.
8. Wash hands .
9. Check the volume remaining in currently infusing IV
fluids.

36. Cont Implemenations
10.Record the total amount of all fluid
intake and output volumes.
11.Compare the data to determine if the intake and
output are approximately the same.
11.Report major differences in I&O to the client’s
physician.

37. 13.Review the plan of care and if the goals have not
been met.
14.Report the I&O volumes IV fluid credit amount, and
or other data.

38. Documentation
1. Date and time.
2. Intake and output volumes for the next shift.
Negative and positive balance:
 If the total intake for the shift > the total
output for the shift negative balance .
 If the total intake for the shift > the total
output for the shift positive balance .
