Short answer: The BIX/CPR100A is a half-body CPR training manikin built to the American Heart Association 2020 international CPR and ECC guideline standard. It teaches compression depth through a combination of something students can feel and something they can see: a clear click is heard at the correct depth, and three indicator lights on the left shoulder show whether the compression is too shallow (yellow), correct (green) or too deep (red). Compression rate is signalled by light patterns across the 80–120 per-minute range, and visible chest rise confirms effective ventilation — which makes it a practical, low-cost entry manikin for nursing and BLS classes.
Key takeaways
| Student action | Manikin response |
| First correct compression | All three shoulder lights illuminate — device and battery confirmed working |
| Correct depth (clear click) | Green light on |
| Compression too shallow | Yellow light — apply more force |
| Compression too deep | Red light |
| Rate below 80/min | One yellow flash |
| Rate 80–100/min | One green flash |
| Rate 100–120/min | Two green lights (target zone) |
| Rate above 120/min | Two green lights + one yellow |
| Artificial respiration | Visible chest rise and fall |
| Session end | Yellow flashes 10 s, then red, then sleep mode |
Compression depth is the parameter students most reliably get wrong, and the parameter they can least judge by themselves. In the landmark in-hospital study by Abella and colleagues, measured compression depth, rate and ventilation frequently fell outside guideline ranges even among trained providers who believed their technique was adequate [1]. An instructor watching a whole class cannot judge 5.4 cm by eye, so the correction arrives late and inconsistently.
Turning depth into an immediate, unambiguous signal — a click plus a green light — converts a subjective instruction into a repeatable target, which is exactly what the AHA's CPR-quality consensus statement recommends: use feedback to correct shallow compressions and excessive rate, the two most common deviations from guideline technique [2]. For a nursing programme, this matters twice over, because simulation-based skills practice is already accepted as a substitute for part of clinical hours; the fidelity of the feedback determines whether those substituted hours build correct habits or entrench wrong ones [3]. The CPR100A gives a class a correct-by-construction target without the price of a full-body electronic simulator.
A recommended progression: teach hand position first, then depth with the lights visible; repeat with the lights covered so students rely on the click and on feel; then add ventilation with chest-rise feedback and finish with the 30:2 sequence to a metronome or counted cadence.
The specification describes the light, click and rate functions above; as a half-body unit it does not simulate a full body, pupils or a pulse, so for advanced assessment scenarios consider a full-body model from the same line. Delivered accessories and power configuration can vary by order — request the official specification sheet before planning a term. This is an educational training aid, not a medical device. Assess against your current resuscitation guidelines [4].
Q1. What is the BIX/CPR100A used for?
Adult basic life support training: hand-position chest compression (depth and rate) and artificial respiration with visible chest rise, for nursing schools, certification centres and in-service CPR refreshers.
Q2. How does it tell a student the depth is right?
Three shoulder lights plus an audible cue: green with a clear click at the correct 5–6 cm depth, yellow when compressions are too shallow, and red when they are too deep.
Q3. Does it give rate feedback?
Yes. Light patterns indicate the compression rate: one yellow flash below 80/min, one green flash at 80–100/min, two green lights at the target 100–120/min, and two green plus one yellow above 120/min.
Q4. Does it show whether ventilation is effective?
Yes — visible chest rise and fall is observed during artificial respiration, so students can see that the breath is delivered.
Q5. Is it full-body?
No. The CPR100A is a half-body (torso) manikin, chosen for tabletop convenience and lower cost. Ask us about full-body models if you need pulse, pupil or printed-report functions.
Q6. How do I get a quotation?
Email adanursing@adaanatomy.com with the model (BIX/CPR100A), quantity and destination; our team will send pricing, lead time and the official specification on request.
Email adanursing@adaanatomy.com for the BIX/CPR100A price list and shipping details. For programmes that need to scale, we can also quote student-grade half-body units in mixed quantities alongside a full-body assessment manikin, so introductory teaching and summative assessment use the same compression standard.
