Moreover the HL7 Vital Signs profiles contain two issues in their current version that prevent them from being used for the exchange of zibs (see below). However, an effort has been made to make this profile consistent with the (other) [HL7 Vital Signs profiles](https://www.hl7.org/fhir/R4/observation-vitalsigns.html), since the zib PulseRate is considered to be a vital sign.

There are also some differences in the profiling approach between the current profile and the HL7 profiles, like the use of patterns rather than slices with fixed systems and codes to enforce the inclusion of some coding (for reasons of consistency with other zib profiles, the former approach has been chosen here).
