The Pneumeric Capnospot® is a novel colorimetric CO₂ detection device that attaches to any commercially available needle decompression catheter via standard Luer fitting to provide objective, visual confirmation of successful pleural entry within seconds. When the needle enters the pneumothorax space, CO₂-rich air produces a clear color change from blue to yellow — replacing the subjective "gush of air" assessment that fails in up to 50% of cases in trained professionals. Winner of the 2023 EMS World Expo Innovation Award.

Product Overview
The standard of care for confirming successful needle thoracostomy has historically been auditory: providers listen for a "rush" or "hiss" of air as the needle enters the pleural space. This method is subjective, highly susceptible to environmental noise (helicopters, gunfire, sirens, crowd noise), and dependent on a tension large enough to produce audible flow. Research has consistently documented a 20–50% failure rate for needle decompression in well-trained professionals — a failure rate that contributes directly to preventable mortality. Data shows that successful therapy reduces 24-hour mortality by approximately 25%.
The Capnospot transforms this ambiguous, high-stakes assessment into an unambiguous binary result: the device turns from blue to yellow when carbon dioxide — which is elevated in the tension pneumothorax space compared to atmospheric air — contacts the colorimetric indicator. The color change occurs within 5 seconds of pleural entry, providing the fastest objective confirmation currently available at the point of injury. If the catheter loses patency or migrates out of the pleural space, the Capnospot reverts to its original blue color — alerting the provider immediately to reposition or replace the catheter.
The science behind this approach is well-established: the gaseous composition of a tension pneumothorax has an elevated partial pressure of CO₂ relative to normal atmospheric air, making colorimetric capnography an ideal confirmation test. The device was initially designed and developed at a leading healthcare organization, and current clinical data demonstrates higher confirmation accuracy than clinical judgment alone — a finding recognized by the FDA, which states the Capnospot is "used for more accurate placement of pneumothorax decompression devices than the current standard of care auditory assessments."
The Problem with Auditory Confirmation
| Limitation | Auditory ("Hiss") Method | Capnospot CO₂ Method |
|---|---|---|
| Noise environment | Severely degraded by helicopter, gunfire, crowds | Unaffected — visual, not auditory |
| Subjectivity | High — depends on operator perception | None — objective color change (blue → yellow) |
| Missed catheter loss | Not detected | Capnospot reverts to blue — immediate alert |
| Low-light use | Auditory only — unaffected | Readable in low-light conditions |
| Confirmation speed | Immediate if tension is large enough | <5 seconds — even for smaller tension volumes |
| Evidence base | Long-standing clinical practice | Clinical data; FDA-recognized accuracy improvement; 2023 EMS World Expo Innovation Award |
How to Use the Capnospot
- Attach the Capnospot to the distal (hub) end of your decompression needle or catheter via standard Luer connection prior to insertion
- Perform needle decompression per TCCC protocol (perpendicular to chest wall, to the hub)
- Observe the indicator: color change from blue → yellow within 5 seconds confirms pleural entry and successful decompression
- If the indicator remains blue, the needle has not entered the pleural space — reposition or attempt at the alternate site with a new needle/catheter unit
- Monitor during dwell: if the indicator reverts to blue after initial yellow confirmation, catheter patency may be lost — reassess and reposition
Clinical Data Summary
- Tension pneumothorax: 100% fatality if untreated — among the most time-critical reversible trauma emergencies
- Needle thoracostomy failure rate: 20–50% in well-trained professionals (published literature)
- Successful therapy: associated with approximately 25% reduction in 24-hour mortality
- Capnospot confirmation speed: <5 seconds from pleural entry
- Recognition: Winner, 2023 EMS World Expo Innovation Award; FDA-recognized accuracy improvement over auditory assessment
