Vital Signs Monitoring
Predictive, not detective
Contactless radar in every room, a personal baseline for every person, and a signal that arrives up to seven days before clinical presentation. Remote patient monitoring built for residential aged care, hospital inpatient wards and corrections.

The costliest moments happen at night
Clinical deterioration shows up in the vital signs first. Changes in heart rate, respiratory rate and movement can be early indicators of UTIs, infection and other physiological issues. Those changes are too subtle to identify on a round, and they unfold between observations, when clinical cover is thinnest.
- 1 in 3 residents present to an emergency department every year
- 28.6% of those transfers are urinary tract infections, often silent until a fall
- up to 40% of those emergency transfers are potentially avoidable
The cost is not only the ambulance. It is the resident who comes back having lost confidence, the staff who absorb that, and the acuity AN-ACC never sees because nobody was watching.

The same gap, six settings
The pressure above is residential aged care. The gap it describes exists anywhere people are checked on a schedule rather than watched continuously.
-
Residential aged care
Falls happen at night when staffing is lowest, and deterioration shows in the vital signs days before an acute event. Continuous oversight with no wearables and no cameras is a least-restrictive alternative under the restrictive practices requirements.
-
Hospitals and local health districts
Observations every four hours leave three and a half hours of blind time. Continuous monitoring stops at step-down, which is where residual risk is highest.
-
Corrections
Welfare checks are interval-based and miss what happens between them. Cameras and worn devices are not viable in a cell. Live with NSW Corrective Services since 2022.
-
Mental health
Inpatient settings need observation that does not escalate distress. Sitter watch and one-to-one monitoring are resource-intensive and hard to sustain.
-
Aged care at home
High-acuity clients are unmonitored for 23 hours or more between visits, and wearables do not work for people with cognitive impairment.
-
Retirement villages
Residents decline in their own unit, where the operator carries the duty of care under Standard 5.4 but has no clinical alarm.
The POBC signal
Probability of Baseline Change compares each person's recent observations against their own established baseline. When the trend shifts in a statistically meaningful way, the platform raises a probability score, often days before a routine round would pick anything up. It is a prompt to review, not an alarm.
Up to 7 days of warning before clinical presentation.
up to 50% fewer resident falls Single-site pilot, April to June 2026. Indicative figures, hand-counted.
How it works
-
Sense
A contactless radar sensor in the room continuously measures heart rate, respiratory rate and movement. No wearables, no cameras, no interaction required.
-
Baseline
The platform builds a personal baseline over the first one to two weeks, learning what normal looks like for this person.
-
Score
POBC compares short-window observations against that baseline and puts a probability score on the clinical dashboard, up to seven days before clinical presentation.
What it is, and what it isn't
The fastest way to understand Vital Signs Monitoring is to be clear about what it does not replace. It sits above your existing stack. Everything already on your floor stays exactly where it is.
What it does
-
Predicts deterioration
Identifies people on a declining trajectory days before risk peaks.
-
Builds a personal baseline
Learns what normal looks like for each person, then watches for movement away from it.
-
Prompts clinical review
Gives the team a daily prioritised list of who warrants attention this morning.
-
Builds an evidence trail
Every observation captured automatically and time-stamped, ready for clinical governance and post-incident review.
-
Not just POBC
High and low thresholds for heart rate and respiratory rate can be set per device, so per bed and per person. A reading outside someone's configured range triggers straight away, alongside the days-ahead trend signal.
What it does not do
-
Not a fall detector
Does not detect the moment a fall occurs. It reduces falls by interrupting the trajectory beforehand.
-
Not a nurse-call replacement
Existing nurse-call and emergency response workflows remain exactly as they are.
-
Not a diagnosis
POBC is a probability score, always paired with clinical assessment. Never a substitute for it.
-
Not predictive on day one
The POBC signal matures once a personal baseline is established, typically after the first one to two weeks. Threshold alerts work from the first night.
-
Not aged care management software
It does not manage care plans, rosters, medication or billing. Vital Signs Monitoring runs alongside your residential aged care software and feeds it a clinical signal it does not otherwise have.
The dashboard at handover. Overnight the sensors gathered around 6,000 readings for each resident, so the morning starts with a short list of who to look at rather than a full round.
One platform, seven capabilities
The same contactless radar carries all of them. Which one leads depends on where it is deployed: predictive care in residential aged care, rapid deterioration in hospitals, acute event detection in corrections.
Leads with
Predictive Care
The POBC signal flags physiological drift up to seven days before clinical presentation, so the team intervenes in the trend rather than the crisis.
-
Rapid Deterioration
Continuous heart rate, respiratory rate monitoring and movement show drift alongside your existing track-and-trigger workflows, giving the clinical team a wider window to assess and act on patient deterioration.
-
Acute Event Detection
Threshold-based alerts for acute events including tachycardia, bradycardia and respiratory distress, with movement context to cut false alarms. Thresholds are configurable per device.
-
Proof of Life
Continuous presence and physiology in every monitored room. It answers non-responsive events in a way cameras and wearables cannot.
-
Clinical Evidence Trail
Time-stamped physiology for every person, building a defensible record for clinical governance in aged care, for the aged care quality indicators, for SIRS reporting including Priority 1 timeframes, and for accreditation and post-incident analysis.
-
Patient Wellness
A per-person wellbeing baseline covering sleep, agitation and restlessness. Continuous observation replaces point-in-time rounds, which returns registered nurse hours and protects Care Minutes.
-
Occupancy
Real-time presence and movement supporting muster, headcount accuracy and after-hours staffing models.
A dignity-first approach
Contactless radar sees physiology, not people. No cameras in the room. No wearables to remember, charge or refuse. People live as they always have, while the monitoring runs quietly in the background and the clinical team gets the signal.
The evidence
-
Warrigal Care, Goulburn
A 160-bed home, live since January 2026. Zero night ambulance call-outs, four months running. In one quarter the POBC review identified 44 infections managed in-home, including 15 UTIs, and no UTI-attributable hospital transfers between March and May.
-
Australian government deployments
NSW Corrective Services has run it since July 2022, beginning in a maximum-security high-risk pod and expanding to the remaining cells. Queensland Police at Wacol and the AFP watch house in the ACT followed. Each agency passed its own procurement, security and clinical governance review.
-
Independently validated
The Validation Institute awarded health outcomes validation to the POBC score in 2024: 201 monitored residents against 2,525 controls, in which POBC predicted 75.6% of hospital transfers up to seven days ahead. The cohort was a United States skilled nursing facility rather than Australian aged care.
-
Recognised
TIME Best Inventions 2024, a Red Dot design award and a CES Innovation Award. The Validation Institute also attaches a US$100,000 credibility guarantee to the claims it validates.
-
Deployed at scale
Xandar Kardian reports more than 150 facilities and over 44,000 people monitored, covering 2,500 patient-years of readings. At one named site, Cloverdale Healthcare Center under Dr Noel Serrano, 30-day hospital readmissions fell by more than half.
-
Peer-reviewed accuracy
Scientific Reports, December 2021. Fifty patients measured against ECG and capnometry at the same time as the radar, returning a concordance correlation coefficient of 0.925 for respiratory rate. Full citation on request.
What the signal came before
POBC does not identify conditions. It flags a person whose physiology has moved away from their own baseline. Where the outcome was recorded afterwards, this is how often the signal came first.
| What followed | Flagged beforehand | Lead time |
|---|---|---|
| Hospital transfer | 76.5% | 5.5 days |
| End of life | 79.5% | 5.4 days |
| Heart failure | 73.2% | 5.3 days |
| Infection | 74.5% | 4.3 days |
| COPD exacerbation | 72.5% | 4.1 days |
| COVID-19 | 71.1% | 4.0 days |
Xandar Kardian platform data, vendor-reported. The infection figure is for urinary tract infection specifically. These are detection rates in cohorts where the outcome was already known, not diagnostic accuracy. They do not say how often the signal appears with nothing following it, which is the question a proof of value on your own floor is there to answer.
How you'd start
Three stages, each with a decision point. Nobody signs up to a rollout on day one.
-
Proof of concept
Around five rooms for 90 days. Opex sized, so there is no capital business case to write. It proves the POBC signal on your own residents with your own clinical team.
-
Proof of value
Twenty-five rooms over a quarter, designed with your clinical lead. It quantifies the registered nurse hours returned and the hospital transfers avoided, and builds the business case in your numbers.
-
Deployment
Once the proof of value is signed off, we scale across your sites, with the evidence framework, training and clinical workflow already proven on your floor.
