Module 1

What the Halo Is

The Halo is a noninvasive vital signs monitor worn behind the ear and on the neck. It measures SpO₂, pulse rate, respiratory rate, core body temperature and skin temperature.
Data flows Halo → LiveCharts app (Bluetooth LE) → Command Cloud (Wi-Fi/cellular) so remote clinicians can monitor patients.
Prescription device for adult patients only. Not for use under age 22, and not for pediatrics or neonates.
Cannot be used on a patient whose ear is injured (burns, lacerations, abrasions, gross deformity).

⚠️

Module 2

Safety Rules & Prohibitions

Never use the Halo while it is charging. Charge only with a 60601-1-approved isolating 5V medical power adapter.
MR Unsafe: never take it into an MRI environment (projectile hazard).
Do not use near electrocautery, electrosurgical units or diathermy. Remove the Halo before using a cardiac defibrillator.
Not an apnea monitor. One person at a time. Do not sterilize, modify or disassemble it (lithium battery fire risk).
Stop using and remove immediately if it is damaged, wet inside, or hot to the touch.
Keep out of reach of children and animals (choking hazard). Avoid any cable wrapped around the neck.

Module 3

Applying & Removing the Halo

Clean ear and neck with an alcohol square or damp cloth, then dry.
Base unit: on the electrode adhesive at the 'Sempulse Point' on the left side of the neck, directly below the ear canal (soft pocket between the scalene muscles and above the trapezius).
Ear sensor: on the posterior cavum concha (back of the ear), roughly 4:00–5:00 on the ear 'clock', cable pointing toward the feet, flush to the skin without excessive pressure.
Power on: press 1 second. Power off: press 5 seconds. Never hold longer than 5 seconds (blue LED = bootloader mode; leave unapplied for 30 seconds).
Remove by peeling the adhesive from the sensor — never pull the wire. Inspect skin integrity at least every 24 hours.

Module 4

LED Indicator Light

Green: readings normal. Yellow: outside yellow thresholds, evaluate. Red: outside red thresholds, evaluate immediately.
Cyan: low-priority alarm. Blinking yellow: medium-priority. Blinking red: high-priority, evaluate immediately.
Alternating white/green: proximity mode — ready to apply, or skin contact was lost (app shows SUGGEST REAPPLY / REAPPLY DEVICE).
Solid or blinking orange: startup test failed or error. Discontinue use and apply a new Halo.
While charging: flashing green = not full, solid green = fully charged. No light = off or battery exhausted.

Module 5

LiveCharts, Alarms & Thresholds

Halo pairs automatically via Bluetooth LE (not traditional pairing); keep the smart device within 5 feet when syncing.
Patients are ranked by severity: Critical (high-priority alarms), Urgent (medium), Routine (low or none).
Yellow thresholds trigger medium-priority alarms (3 chirps); red thresholds trigger high-priority alarms (10 chirps). Alarms are disabled by default and non-latching.
Check the patient first when an alarm sounds. Never set extreme thresholds. Observe patients by other means when alarms are paused or off.
Add a wrongly-connected Halo to the Ignore List. Low battery alarm fires at 5%.

Module 6

Cleaning, Storage & Troubleshooting

Clean after every patient with soapy water, disinfecting wipes, chlorhexidine wipes, bleach solution or isopropyl alcohol. Never submerge it.
Charge fully before first use; battery lasts over 40 hours and charges in under 4 hours. Expected service life: 1 year.
Operating temperature 32–104°F recommended; store upright between -40°F and 158°F.
Weak readings: check ear sensor contact, extraneous light, motion and charge. Replace adhesive or the Halo if it will not stay on.
If Bluetooth or network drops, keep monitoring the patient — the Halo and LiveCharts cache data and upload when reconnected.
