Table 5: List of satisfaction evaluation for the VCMS. patient monitor, and the time for clinical staff to adapt and master the VCMS devices can be minimized. The numerical parameters were also configured to display values transmitted in real time from the patient monitor and to display up to nine values in one thumbnail. Each parameter can also be set independently of the patient's monitor. Figure 3c shows an enlarged thumbnail image of box B among the ventilator thumbnails. The display method was the same as that for the abovementioned patient monitor. Figure 3c shows the screen of the VCMS when an alarm occurs in the V-ACV mode. The parameter thumbnail that triggers the alarm and the cause of the occurrence on the upper-right side are displayed together with the red area. At that time, a high-decibel voice is generated by a speaker connected to the VCMS so that the clinical staff can immediately determine the patient and the cause of the alarm. The clinical staff can adjust the alarm level, and the default value is set below the dB(A) recommended by the WHO [18]. When an alarm occurs in various parameters, the red area is displayed on the parameter thumbnails simultaneously, and the alarm produces an indication in the upper-right and is displayed every 1 s. All alarms are maintained until the data are transmitted within the threshold value for each parameter, which can be set differently from the parameter thresholds of the patient monitor and ventilator.
