The accuracy of parameters displayed on-screen was tested using calibrated instruments and the % error for each parameter was as follows:
Display Pressures (Claimed accuracy 5.5% or better)
- 5 cm H2O ± 5.5%
- 37 cm H2O ± 2.0%
- 50 cm H2O ± 1.3% (by extrapolation)
Display Volumes (Claimed accuracy 4% or better)
| Vexp | MV |
| 205 mL ± 3.4% | 2,795 mL ± 3.6% |
| 484 mL ± 1.4% | 6,305 mL ± 3.7% |
| 721 mL ± 0.7% | 9,336 mL ± 1.9% |
| 800 mL ± 0.6% (by extrapolation) | |
Display Oxygen (Claimed accuracy 3% or better)
- 30% ± 2 %
- 60% ± 1%
- 90% ± 1%
FIO2 System Response Time
The response times (See Overview of the LycoVent: Oxygen Level Control) are based on the time to achieve 90% of a target FiO2 of 60% from a starting FiO2 of 22% (air) through the addition of medical grade O2 (99%).
