24.1 RM Introduction
The RM monitoring enables clinicians to understand the ventilator/anesthesia machine operation and patient
respiratory status. In the respiratory mechanics (RM) monitoring, the airway pressures are measured, from the
part between the patient circuit and intubation tube, using a flow sensor between the Y-piece of patient circuit
and the patient connection. The pressure is transferred to the monitor through the tube and measured by a
pressure transducer in the RM module. The pressure difference together with the gas concentration information
is used to calculate flow. The volume information is obtained by integrating the flow signal. From these three
parameters, other parameters such as RR, I:E, Compl, etc. are derived.
RM monitoring is intended for adult and pediatric patients.
24.2 RM Safety Information
WARNING
• RM monitoring is not intended for neonatal patients.
• RM monitoring is for mechanically ventilated patients only.
• The RM module is not intended to be used with high frequency ventilators.
24.3 RM Parameters
RM monitoring displays the following waveforms and loops:
■ Flow waveform
■ Paw waveform
■ Vol waveform
■ FV (flow-volume) loop
■ PV (paw-volume) loop
RM monitoring provides values for 18 parameters. The 18 parameters can be classified into 4 categories:
(1) RM menu hard key (2) Enter/Exit the respiratory Loops
(3) Module status indicator (4) Flow sensor connector
