Vitals Telemetry: Connecting Home Monitors to Doctor Workflows

Remote patient monitoring enables constant care for patients with hypertension, diabetes, or cardiovascular diseases. By feeding telemetry data directly from smart blood pressure monitors, ECG wearables, and glucose sensors to custom EHR dashboards, doctors can intervene before critical incidents occur.

RPM Infrastructure

Connecting diverse consumer and medical-grade IoT devices requires a structured telemetry gateway. Devices push raw data to a secure mobile app endpoint, which aggregates records and formats them as HL7-compliant telemetry packets.

Bluetooth Vital Records API

Below is a TypeScript gateway snippet demonstrating vital signs ingestion, payload validation, and triggering database threshold warnings if patient vitals cross safe ranges:

interface VitalTelemetryPayload {
  patientId: string;
  deviceType: 'GLUCOMETER' | 'BLOOD_PRESSURE' | 'ECG';
  readingValue: number;
  unit: string;
  measuredAt: string;
}

export async function ingestVitalReading(payload: VitalTelemetryPayload): Promise<{ status: string; alertTriggered: boolean }> {
  // Validate measurements
  if (payload.readingValue <= 0) {
    throw new Error("Invalid medical telemetry reading.");
  }

  let alertTriggered = false;
  // Example threshold check for blood glucose (mg/dL)
  if (payload.deviceType === 'GLUCOMETER' && (payload.readingValue > 250 || payload.readingValue < 70)) {
    alertTriggered = true;
    await triggerClinicalAlert(payload.patientId, `Critical glucose reading: ${payload.readingValue} ${payload.unit}`);
  }

  await saveToVitalsDatabase(payload);
  return { status: "SUCCESS", alertTriggered };
}

Structuring Doctor Alerting

To avoid warning fatigue, dashboards must prioritize vital alerts. Doctors should see telemetry data arranged on a visual timeline, highlighting deviations from standard baselines, while clinical staff manages low-risk alerts.
