Consider PCA as a process rather than just a machine
that delivers medication. The PCA process comprises
the PCA machine, prescription for medication delivery, medication, and patient; if one of these elements
isn’t present or is faulty, the process will fail.
The human component of this process also includes
the nurse who must program the pump correctly
and monitor the patient, the pharmacy staff who
must deliver the correct medication with the correct
concentration, and the prescriber who must be
knowledgeable about writing PCA prescriptions.
