It's not able to identify the unit of measure. Would you mind sharing the POST body?

Hi Fenil,

I tried again -- the code was "code": "bpm" the previous request ID. I changed it to - "code": "/min". Please find below the latest Request ID with the post body.

Thank you so much.

Always best to query an existing value in the EHR with FHIR, to fully understand the expected values to POST. This was a query on blood pressure for out EHR:

"valueQuantity": {

"value": 135,

"unit": "mmHg",

"system": "http://unitsofmeasure.org",

"code": "mm[Hg]"

},

Note bpm ("beats per min" relate to heart rate / pulse rate / etc)

Thank you so much Michael!

I did query for the patient - 12457978 in Cerner sandbox and found unit - mmHg and code - mm[Hg]. It did not work, same error code-422 and Unprocessable entity . No details about the error so I was trying different unit and code (bpm and /min) combination. Please find below the Post Body and the request-id in postman. I tried to send the "value quantity" as component but that also didn't work and tried blood pressure code (

So any help would be highly appreciated.

That LOINC doesn't seem to be mapped on our side. Please use other LOINC such as 8454-1

{

"system": "http://loinc.org",

"code": "8454-1",

"display": "Diastolic blood pressure--standing"

}

Thank you so much Fenil!

I really appreciate your help!!. Could you please send me LONIC code for (Systolic blood pressure) and (heart rate / pulse rate)?

Also please confirm "component":" is supported for Blood Pressure.
