How does the Capnospot confirm needle decompression success?
The Capnospot uses colorimetric capnography — the same technology behind CO₂ detection indicators used in airway management — to detect elevated CO₂ in the tension pneumothorax space. When the catheter enters the pleural cavity, CO₂-rich air contacts the indicator and produces an unambiguous color change from blue to yellow within 5 seconds. This provides objective, binary confirmation ('yes' or 'no' for CO₂ presence) without relying on auditory assessment or subjective clinical impression.
What decompression devices is the Capnospot compatible with?
The Capnospot attaches via a standard Luer fitting and is compatible with virtually all commercially available needle decompression devices, including the NAR ARS® (10 Ga. and 14 Ga.), the NAR Enhanced ARS®, the NAR SPEAR®, and any other Luer-compatible needle or catheter system. The needle/catheter is not included with the Capnospot — it attaches to your existing decompression device. Note that Capnospot compatibility with specific decompression devices should be verified per manufacturer guidance.
What is the failure rate for standard needle decompression and how does the Capnospot address it?
Published literature documents a 20–50% needle thoracostomy failure rate in well-trained professionals — driven primarily by difficulty confirming pleural entry in noisy, high-stress environments. The Capnospot addresses this by providing visual, objective confirmation that eliminates the subjectivity of auditory assessment. Additionally, if the catheter loses patency after initial successful placement, the indicator reverts from yellow to blue — alerting the provider immediately and enabling faster corrective action.
Has the Capnospot received any FDA or regulatory recognition?
Yes. The FDA has stated that the Capnospot is 'used for more accurate placement of pneumothorax decompression devices than the current standard of care auditory assessments.' The Capnospot was also awarded the 2023 EMS World Expo Innovation Award — recognition from the emergency medical services community for a meaningful advance in point-of-care technology. Clinical data collected since its development at a leading healthcare organization demonstrates higher confirmation accuracy than clinical judgment alone.
Does the Capnospot work in dark or noisy environments?
Yes. The Capnospot was specifically designed for the operational and clinical environments where needle decompression is most likely to be performed — including helicopter transport, tactical casualty care, and mass casualty scenarios. Unlike auditory confirmation (which is severely degraded by helicopter rotor noise, gunfire, and crowd noise), the Capnospot's color change is a visual signal that functions regardless of ambient noise level. The indicator is also readable in low-light conditions, making it functional across day, night, and degraded visibility scenarios.
