The solution

Explainable triage, not a black box

TiPSY is a deterministic, auditable rule engine. Every alert can be traced to the vitals that caused it, which is what makes it clinically deployable today.

Pipeline

From raw signal to acknowledged alert

01

Acquire

Bedside monitors stream ECG, SpO₂, heart rate and blood pressure to the TiPSY gateway over the hospital IoT network.

02

Personalise

Each bed carries clinician-set limits for that patient's diagnosis, age and baseline — no overgeneralised defaults.

03

Corroborate

An abnormal ECG is held until SpO₂, HR and BP are assessed. If they are normal, the event is classified as artefact or lead contact loss.

04

Prioritise

The rule engine assigns Tier 1, 2 or 3 and shows the exact parameters that produced the decision.

05

Escalate

Unacknowledged alerts re-fire at rising urgency and route to the next responder until a clinician confirms.

06

Learn

Clinicians mark alerts as real or non-actionable; that feedback tunes thresholds and reduces future false alarms.

Priority model

Three tiers, one rule: noise never gets a siren

Only fatal events and alerts left unattended are promoted to high-pitched audible alarms.

Tier 1 — Yellow

Advisory

A single parameter drifts outside the patient's personalised range while others stay normal. Silent visual cue at the console; logged for trend review.

Tier 2 — Orange

Actionable

Two or more parameters agree, or a Tier 1 event persists. Visual pulse plus soft chime; nurse acknowledgement expected within the response window.

Tier 3 — Red

Life-threatening

Corroborated severe arrhythmia, desaturation or hypotension. High-pitched alert, bed highlighted, escalation timer starts immediately.

Worked example

Abnormal ECG on bed 4

The same waveform can be an emergency or an electrode problem. The difference is context.

Suppressed — artefact

  • ECG · irregular, wide complexes
  • SpO₂ · 98% (normal)
  • HR · 82 bpm (normal)
  • BP · 118/74 (normal)

No corroboration. Flagged as motion artefact / loose electrode, shown visually, no audible alarm.

Escalated — Tier 3

  • ECG · irregular, wide complexes
  • SpO₂ · 86% (falling)
  • HR · 168 bpm
  • BP · 72/44 (hypotensive)

Multiparameter agreement. High-pitched alert, bed flagged, escalation timer runs until a clinician acknowledges.

The console

One view of every bed, on any hospital device

Tiered badges, live waveforms and acknowledgement state — the same interface on a workstation, laptop or tablet.
