K2 Guardian Integration

Integrate your digital health solution with K2 Guardian using 6B’s secure, standards-based healthcare interoperability services. We connect maternity applications, fetal monitoring systems, clinical decision-support tools, patient records, analytics platforms, and wider hospital systems with Guardian – enabling reliable data exchange across labour, birth, and intrapartum care pathways.

Get in touch

Trusted by NHS organisations, maternity providers, and healthtech innovators, 6B delivers full-lifecycle K2 Guardian integration, from discovery and architecture through development, testing, deployment, and ongoing support. We build secure, scalable integrations for digital CTG capture, fetal monitoring, labour ward documentation, clinical alerts, situational awareness, dashboards, and reporting.

Our team combines intrapartum workflow knowledge with expertise in healthcare APIs, HL7 FHIR, HL7 messaging, medical-device interfaces, identity management, event-driven integration, and clinical safety. We support time-sensitive labour ward workflows while protecting data integrity and maintaining continuity across maternity systems.

Understanding K2 Guardian

K2 INFANT-Guardian is an intrapartum maternity system that supports digital fetal monitoring, clinical documentation, and labour ward situational awareness.

The platform captures CTG information from connected fetal monitors and presents fetal heart-rate data alongside relevant clinical information during labour.

Guardian supports contemporaneous documentation and enables maternity teams to view activity across the labour ward, helping clinicians maintain oversight of women receiving intrapartum care.

The system can also support computer-assisted interpretation of fetal monitoring information while maintaining clinical responsibility with the maternity team.

Within the wider K2 ecosystem, Guardian can work alongside systems such as K2 Athena to support continuity between maternity records, labour ward documentation, fetal monitoring, and birth information.

Our K2 Guardian Integration Process

We begin with structured discovery involving maternity, obstetric, operational, digital, technical, medical-device, and governance stakeholders. Together, we define workflows, users, data requirements, safety constraints, and intended outcomes.

Typical integrations include demographics, admissions, maternity records, fetal monitoring devices, CTG information, observations, clinical alerts, labour documentation, birth events, reporting, and analytics.

We map maternal and fetal identifiers, pregnancies, encounters, monitoring sessions, risk factors, observations, clinical assessments, labour events, interventions, birth details, and associated documentation.

Particular attention is given to relationships between the pregnant person, pregnancy, fetus, monitoring session, labour encounter, newborn, and birth event.

Architecture may use HL7, FHIR, REST APIs, secure web services, integration engines, medical-device interfaces, document exchange, contextual launch, or event-driven messaging. Authentication, role-based access, audit, encryption, lawful access, and emergency access are designed from the outset.

Reusable components accelerate delivery, including FHIR handlers, HL7 parsers, device connectors, identity-matching services, validation rules, and routing pipelines. Testing validates identities, monitoring associations, event sequencing, permissions, performance, audit trails, device connectivity, failure recovery, and downtime reconciliation.

Before launch, we coordinate acceptance testing, clinical safety review, deployment, training, and documentation. After go-live, we monitor integrations, resolve issues, and maintain compatibility with Guardian, connected devices, and NHS systems.

Benefits of K2 Guardian Integration

Midwives and obstetric teams gain timely access to fetal monitoring, maternal information, observations, clinical documentation, and labour events without repeated entry.

Digital CTG capture supports contemporaneous, traceable documentation throughout labour while reducing reliance on disconnected systems and manual information transfer.

Labour ward teams gain improved visibility of activity and closer links between fetal monitoring, clinical documentation, and situational awareness.

Device integration reduces manual handling of monitoring information and helps maintain accurate associations between patients, pregnancies, fetuses, and monitoring episodes.

Operational and safety teams gain structured information for reporting, audit, incident review, service monitoring, and improvement.

For healthtech vendors, K2 Guardian integration provides standards-based access to established intrapartum and fetal-monitoring workflows.

What best describes your integration goal?

Readiness checklist for K2 Guardian Integration

  • Define the intrapartum workflows your integration will support, such as admission, fetal monitoring, observations, labour documentation, clinical alerts, birth events, reporting, or analytics.
  • Identify the Guardian, Athena, EPR, PAS, fetal-monitoring devices, maternity systems, integration engines, and third-party applications involved in each workflow.
  • Confirm which APIs, FHIR resources, HL7 messages, device interfaces, document connections, or secure transfer methods are available within the target deployment.
  • Map maternal, pregnancy, fetal, monitoring-session, encounter, and newborn identifiers, including NHS numbers, local identifiers, temporary records, and multiple-birth relationships.
  • Define which system will act as the source of truth for demographics, pregnancy information, admissions, monitoring data, observations, labour events, and birth information.
  • Confirm authentication, authorisation, role-based access, emergency access, encryption, service-account, device, network, and audit-logging requirements.
  • Prepare governance and clinical safety documentation, including the lawful basis, DPIA, DSPT position, and applicable DCB0129 or DCB0160 responsibilities.
