Hello everyone, I have a few questions about calculating the rate of the IV Piggyback. After you connect the IV piggyback with the primary solution, are you supposed to use the regulator clamp of the primary solution to calculate the drip rate? When calculating the drip rate, are you looking at the drip chamber of the primary solution or the drip chamber of the IVPB? Are the numbers for calculating the drip rate come from the order of the primary solution or the order of the IVPB? Thank you so much.
