When indicated two tolerances, consider the highest value.

1 mbar (milibar) = 1 hPa (hectoPascal) = 1.016 cmH2O (centimeter of water). In practice, these units are not differentiated and can be used as:
1 mbar =
1 hPa ≈ 1 cmH2O
(3)
For airway resistance exceeding 150 cmH2O/L/s expiratory volume monitored will have tolerance changed to 10%. In this condition, the inspired volume measured
remains unchanged.
(4)
Tolerance calculated for frequency of 12 , 20 and 30 rpm, respectively, for adult, pediatric and neonatal sensors. Tolerance is a function of the uncertainty of volume
multiplied by frequency.
(5)
700 hPa corresponds to an altitude of 3048m
(6)
All monitoring data are considered at ATPD (Ambient, Temperature and Pressure Dry).
(7)
The Ventilator does not generate negative pressure during expiratory phase.

CO2(mmHg)=CO2( %) x Patm(mmHg)x 0.75

Volume, flow specifications associated with the ventialdor respiratory system are expressed in BTPS with 50% oxygen concentration.

Since pulse oximetry equipment measurements are statistically distributed, it can be expected that only about 2/3 of pulse oximetry equipment measurements will be
within ± Arms of the value measured by a co-oximeter. .

Masimo SET technology with Masimo sensors has been validated for heart rate accuracy in the 25-
240 bpm range on bench tests with a Biotek Index 2 ™ simulator.
This variation is equal to ± 1 standard deviation. ± 1 standard deviation covers 68% of the population.

Ventilation with cyclic pressure up to
100 cmH2O can add up to 2% tolerance
error.

Parameter accuracy may be affected
under the following conditions:
o
Reuse
of
single
use
accessories;
o
Incorrect sensor usage for
patient type;
o
Secretion in the circuit and flow
sensor;
o
Uncalibrated oxygen cell and
flow sensor;
o
Condensation in circuit, flow
sensor and gas inlet;
o
Use
of
nebulizer
with
capnography sensor;
o
Proximal flow sensor with
tubes facing down.
•
To maintain fan accuracy, keep the flow
sensor, breathing circuit, and gas inlet
dry, clean and free of condensation.
