CARESCAPE ONE User Manual DRAFT 26 October 2017
Parameter specifications
The effects of interfering gases and vapors shall be as follows:
ISO 806061-2-55 Table 201.105 Test gas levels of interfering gases and vapors in nominal atmospheric
pressure, i.e., 760 mmHg:
Effects of interfering gases and vapors
Effects of non-interfering gases and
vapors
322
Effect of Helium (50% vol): decreases CO
Effect of N O (30% vol): increases CO

A gas is non-interfering if its effect to the measured CO
follows:
0-40 mmHg: ±1 mmHg additional error
41-70 mmHg: ±2.5% additional error
71-100 mmHg: ±4% additional error
101-150 mmHg: ±5% additional error
