Monitoring RM
17.1 Introduction
In the respiratory mechanics measurement, 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 parameter, other
parameter such as RR, I:E, Compl, etc. are derived.
The RM monitoring enables clinicians to understand the ventilator operation and patient
respiratory status.
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. Paw parameters
Connector for RM sensor
Setup key
Indicator
Calibrate
