How Trumpet Curves can be Used
How Trumpet Curves can be Used
Trumpet curves can be important sources of information for the medical
professional who must decide whether a certain infusion pump can be
used with a particular drug. For example, when delivering a drug with a
short half-life, very small deviations in flow over the course of an
infusion would be desirable to ensure that the deviations in plasma level
also remained small. The pump’s ability to deliver very closely to the
programmed rate would ensure that the drug’s efficacy was being
maintained. In this example, the medical professional would be wise to
select a pump whose trumpet curve indicated a small or narrow range of
deviations in flow rate.
