7 Monitoring
7.4.2 Performing a static P/V maneuver
Refer to Chapter 9, P/V tool maneuver option, for details.
7.5 Monitored parameters
NOTE:
• The HAMILTON-G5 automatically measures inspira-
tory and expiratory resistance (Rinsp and Rexp),
compliance (Cstat), and AutoPEEP breath by breath,
during mandatory and spontaneous breathing in all
modes, without interruption in ventilation. To obtain
these measurements, the device uses a statistical
technique called the least squares fitting (LSF)
method. This method is applied on a breath-by-
breath basis, without the need for special inspiratory
flow patterns and occlusion maneuvers, when the
patient is relaxed or nearly relaxed.
• Actively breathing patients can create artifact or
noise, which can affect the accuracy of these mea-
surements. The more active the patient, the less
accurate the measurements. To minimize patient
activity during these measurements, you can choose
increased Psupport by 10 cmH2O. After completion,
return this control to its former setting.
Table 7-1 is an alphabetical list of the device’s monitored
parameters. The display of monitored parameters is updated
every breath.
