11. Be able to calculate the ideal tidal volume to be delivered to a patient for IPPB therapy.
To Calculate Ideal Body Weight:
- Adult Male-106 + [ 6 (height in inches-60) ]
- Adult Female-105 + [ 5 (height in inches � 60) ]
Once IBW is obtained convert to Kg by dividing by 2.2
- Ex. A woman who is 5�3�� obtain IBW in Kg
- 105 + [ 5 (63-60)] = 120
- 120/2.2 = 54.5 may round if desired
- To obtain minimal accepted IPPB tidal volume:
- (for medication delivery)
10-15 mL/Kg of ideal body weight
- Ex. 5�3�� woman
- IBW in Kg = 54.5 or 55
- 55 X 10 = 550
- 55 X 15 = 825
- Or
- 30% of predicted Inspiratory Capacity
- Ex. 5�3�� woman
- IBW in Kg = 54.5 or 55
*Multiplying the IBW in Kg by 50 will give the predicted Inspiratory Capacity, you are looking for 30% of that volume.
55 X 50 X .30 = 825
- To obtain the Target Volume or Goal:
- (for hyperinflation)
- 75% of the predicted Inspiratory Capacity
- Ex. 5�3�� woman
- IBW in Kg = 54.5 or 55
*Multiplying the IBW in Kg by 50 will give the predicted Inspiratory Capacity, you are looking for 75% of that volume.
55 X 50 X .75 = 2063
