Clinical Practice Guidelines, published by HL7 International / Clinical Decision Support. This guide is not an authorized publication; it is the continuous build for version 2.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/cqf-recommendations/ and changes regularly. See the Directory of published versions

Request to administer LASIX PO as part of a congestive heart failure pathway
CHF Net Intake/Output (in L/day) Profile
CHF Oxygen Saturation (%) Profile
Request to measure oxygen saturation as part of a congestive heart failure pathway
