Patient Ventilation Data

Hello!
I’m new to FHIR and dug through the documentation. Can anyone point me to the right place where to store/retrieve patient-ventilation data?
Thanks!

Are you interested in “number of patients on ventilators”, “# of ventilators available”, and things like that, or are you interested in capturing the specific mixture of gases being delivered to a patient at particular periods of time?

Hello @lloyd,
thank you for your response!

I’m interested in capturing and querying the specific mixture of gases being delivered to a patient at particular periods of time, including:

  • Inhale & Exhale Ration
  • Ventilation Mode (e.g. CPAP)
  • Mesurements of ventilation parameters at a timestamp (e.g. FiO2 (%) )

The only thing I’ve found so far is the following:
https://www.hl7.org/fhir/servicerequest-example-ventilation.json.html
https://build.fhir.org/valueset-servicerequest-orderdetail.html -> for ventilation-mode?

Consider Procedure. It will need some extensions.

The HL7 Patient Care work group (that owns Procedure resource) discussed this question on Aug 20, 2020.

Generally speaking, Patient Care doesn’t recommend using Procedure for the examples provided. Instead, patient data documentation related to output/measurements/readings off a ventilator would be an Observation. Observation.device can reference the specific ventilator (Device) and/or DeviceMetric (for device settings).

Since there could be multiple use cases, please elaborate on which is of primary interest.

  • What is being ordered (ServiceRequest)
  • Vent settings, which can often change (DeviceMetric)
  • Documentation of the vent settings for the patient (Observation) as well as patient’s physiological response (Observation)
