What happens if there is any reduction or a temporary halt of the breath flow rate?

• A. The instrument will reset and request another sample.
• B. The instrument ignores and continues.
• C. It records a zero reading.
• D. It prompts for a blood sample.

Answer: (A)

Maintaining steady, adequate breath flow is essential for the EC/IR II to obtain a valid result. If there’s any drop in flow or a temporary stop, the device cannot capture the required alveolar air, so it cancels the current attempt, resets, and asks for another breath sample. This prevents invalid readings from partial or interrupted blows. It won’t simply ignore the interruption, it won’t record a zero reading from that sample, and it won’t prompt for a blood sample—the device handles a fresh breath sample instead.
