Hi Helmut,

Thanks for your reply.

❝ Be aware that the dose will not be correct since likely you lost a part by flushing the tube. Whether this is really relevant depends on the lost volume / total infusion volume.

The dose is not lost because the nurse expel the burble by squeezing the tube to float the burble up from the liquid surface of the tube.

❝ 2. only if you lost nothing […] the C_max and AUC will equal the one with a constant rate infusion.

❝

❝ Example: t_½ 8 h, infusion interrupted after 15 min for 5 minutes, adjusted infusion rate, no dose lost.

❝

From the above picture, if the dose is not lost, can i say just the AUC will be effect but the Cmax is the same with the canstant rate infusion?
