All rate calculations are based on a 20 drop/ml blood administration set.
For Packed Red Blood Cells
If PCV is known
Volume required: - (calculated at 1ml/kg to raise PCV by 1%)
If PCV is unknown
If patient's PCV is unknown give: - (calculated at 1ml/kg to raise PCV by 1%)
Drip rate
Initial rate: 1 drop every seconds (0.5ml/kg/hr)
Subsequent transfusion rate: 1 drop every seconds (5ml/kg/hr)
*Please round up to the nearest whole number for your drip rate unless you are working with a syringe driver or infusion pump
Calculate dose and administer each unit < 4 hours. As a general estimate, 1ml/kg of Packed Red Blood Cells will raise PCV by 1% or the haemoglobin by 0.3g/dl. Always administer using a blood administration set or suitable inline blood filter.
Rate of Administration: Start transfusion at a rate of 0.5-1ml/kg/hr for the first 15-30 minutes, then according to patients' fluid status, if hypovolaemic, at rates up to shock doses (as fast as blood is being lost), if euvolaemic 5-10ml/kg/hr, if compromised circulation (cardiovascular compromise/renal failure) 1-2ml/kg/hr.
Calculated duration of transfusion
Below shows the approximate length of time it will take to administer the FULL calculated dose at the rates shown.
All breached units should be discarded after 4 hours. Where the delivery duration exceeds this and the volume being delivered is from a single unit bag (and not multiple units), the unit may need to be separated into smaller volumes (see Unit Separation Guidance Document), or the rate may need to be adjusted to complete the delivery of the breached unit within 4 hours. Platelet Concentrate should be delivered over 2 hours or less if the patient has life-threatening haemorrhage. Care must be taken with volume sensitive patients to ensure that the infusion rates are safe and that any pre-existing diseases and the volume status of the patient have been considered before rates are increased. This is the responsibility of the veterinary professional administering the transfusion.

For Plasma (Fresh Frozen Plasma or Frozen Plasma and Cryo-Supernatant)
Minimum amount to give: - (calculated at 10ml/kg)
Maximum amount to give: - (calculated at 30ml/kg)
Drip rate
Initial rate: 1 drop every seconds (0.5ml/kg/hr)
Subsequent transfusion rate: 1 drop every seconds (5ml/kg/hr)
*Please round up to the nearest whole number for your drip rate unless you are working with a syringe driver or infusion pump
Calculate dose and administer each unit < 4 hours. Standard dose: 10-30ml/kg to effect. Severe coagulopathies require the higher end of the dose range. Always administer using a blood administration set or suitable inline blood filter.
Rate of Administration: Start transfusion at a rate of 0.5-1ml/kg/hr for the first 15-30 minutes, then according to patients' fluid status, if hypovolaemic, at rates up to shock doses (as fast as blood is being lost), if euvolaemic 5-10ml/kg/hr, if compromised circulation (cardiovascular compromise/renal failure) 1-2ml/kg/hr.
For the management of hypoalbuminaemia, Fresh Frozen Plasma, Frozen Plasma and Cryo-supernatant should be administered as a constant rate infusion. Higher rates of infusion are typically associated with greater increase in albumin. Dogs receiving plasma for hypoalbuminaemia should be monitored carefully for signs of volume overload. Read more on using plasma for albumin replacement.

For Cryo-Precipitate
Units to give:
*Unit approx 60ml
Calculate dose and administer each unit < 4 hours. Standard dose is 1 unit/10kg. Additional amounts may be required for actively bleeding haemophiliacs/vWD. If used as a pre-treatment of coagulopathy before surgery, the dose should be given within 4 hours of the event. Always administer using a blood administration set or suitable inline blood filter.
Rate of Administration: Start transfusion at a rate of 0.5-1ml/kg/hr for the first 15-30 minutes, then according to patients' fluid status, if hypovolaemic, at rates up to shock doses (as fast as blood is being lost), if euvolaemic 5-10ml/kg/hr, if compromised circulation (cardiovascular compromise/renal failure) 1-2ml/kg/hr.
Drip rate
Initial rate: 1 drop every seconds (0.5ml/kg/hr)

Calculate dose and administer each unit < 4 hours. As a general estimate, 2ml/kg of Whole Blood will raise PCV by 1% or the haemoglobin by 0.3g/dl. Always administer using a blood administration set or suitable inline blood filter.

For Platelet Concentrate
Number of units of platelet concentrate required: - (one unit = approx. 65ml)
Calculate dose and administer each unit < 2 hours. Standard dose is 1 unit/10kg. The required dose may be more or less than the standard dose. Patients should continue to be treated until appropriate resolution of clinical signs. Because there is no standard dose that treats all patients in all clinical settings, the clinician's careful judgment must dictate the appropriate dosage and administration on a case-by-case basis. Always administer using a blood administration set or suitable inline blood filter.
Rate of Administration: Start transfusion at a rate of 0.5-1ml/kg/hr for the first 15-30 minutes and aim to complete administration within 2 hours. The product can be administered quickly (within 30 minutes to 1 hour) to stop life threatening haemorrhage following the initial slow infusion.
Drip rate
Initial rate: 1 drop every seconds (0.5ml/kg/hr)
Subsequent transfusion rate: 1 drop every seconds (delivery over 90 minutes)
*Please round up to the nearest whole number for your drip rate unless you are working with a syringe driver or infusion pump. Drip rate is based on 20 drops/ml.

The blood calculator is a simple tool to help you calculate the required volume for blood administration. Pet Blood Bank is aware that each patient is an individual and will have individual requirements and needs that must be taken into consideration in order to support them through the illness they are facing. Therefore, a veterinary surgeon should use their clinical knowledge when using this blood calculator to decide on the volume each patient requires. It is the responsibility of the veterinary surgeon to ultimately decide on the volume and administration rate for each patient under their care.
