1. Inspiratory CO2 (InCO2) not available.

2. Tracing of anaesthetic inhalational agent not available.

3. Need to discharge and admit patients is rather irksome.

4. Moving tracings give me nystagmus. This is purely a personal preference and I am sure many anaesthetists prefer this mode.

5. Unable to change time easily, especially while monitoring is in progress.

6. On main screen, rather than defaulting to a fixed selection, the cursor remains on the last selection which means you have to look for the current cursor position before making your new selection.

7. After making selections, it may require up to 3 clicks to return to the Main Screen.

1. The display of ETCO2 and ETAnaes on a different page in Tabular Trends makes life extremely difficult. The separation of the View Older/Newer selections from the Page Down/Up selections makes it even more problematic. Furthermore, on the last page of data, it is not possible to Page Down again to see the 1st page of data. Instead, you have to change your selection to Page Up to cycle back again to the 1st page.

2. Changing the Time Interval of the Tabular Trend display requires 2 turns and 2 presses. Furthermore, after you're finished you must change it back to your normal setting. Otherwise, when you next view the trend data, it will be displayed in the last chosen interval. To change back to your original setting requires another 2 turns and 2 presses.

3. There are too few readings per page, meaning more scrolling is needed to see all the data you want.

4. Repeat of "boundary" readings from page to page reduces displayed data points even more and may result in confusion and double charting.

5. Readings in Patient Data, Tabular Trends is not displayed until after time period indicated at top. Hence, if NBP reading was completed at, for example, 10:05:20, this will not be displayed in the Tabular Trends until after 10:06:00. Therefore, if you enter the Tabular Trend display at 10:05:30, although the NBP reading is already completed, you will not see the NBP reading in the trend display as most users would expect.

1. The alarms are "latched". It is possible to stop the alarm for 1, 5 or 15 min, or indefinitely but this has the unsatisfactory side effect of silencing all other alarms as well during the same period.

The Silence function should only silence the alarm condition that was active at the time the function was activated. If the original alarm was corrected but recurred during the period of "Alarm Silence" or if any other alarm conditions arise the alarm should be activated. Furthermore, in the case of the NBP reading, pressing silence should cancel the alarm permanently until the next NBP reading.

2. The Alarm Silence button cycles through Alarm Silence, Pause 5 min, Pause 15 min, and Paused if there is an alarm condition when the button is first pressed but it skips the first choice if there is no alarm condition at the time the button is pressed, i.e. the cycle is Alarm Pause 5 min, Pause 15 min, and Paused. This inconsistency is again very confusing and you have to look at the display carefully to make sure that the correct selection is made.

3. When adjusting the alarm limits, the value initially changes 1 unit by 1 unit, and after the first 5 units, the value changes in steps of 5 units. The range of values where the value changes slowly remains the same, e.g. if the initial alarm limit was as 140, the range where the value changes unit by unit is from 135 to 145 and this does not change. This is illogical and unintuitive. If you want to change the limit, in all probability, you would want to change it significantly, i.e. you are unlikely to change to a value close to the original. In the example above, you are unlikely to want to change to 142 or 137. You am far more likely to select a value of 150 or 160. It would be far more intuitive to make the knob speed sensitive, so that when you turn the knob quickly, the values should change quickly and when you turn the knob slowly, the values should also change slowly.

4. Default Alarm Limits (RR, Sys NBP) seem poorly chosen. This is again a personal preference and not everyone will agree with me here.

1. To synchronise the NBP readings with real time, you need to go into the NBP Menu, set NBP Auto OFF and then back to the desired repeat interval at the appropriate moment.

2. To stop all subsequent NBP readings, you must select OFF for the NBP Auto (3 twists, 4 presses). On most other monitors, a single press is all that is needed.

3. Time displayed on Main Screen is time for start of NBP reading, while time displayed in Patient Data, Tabular Trends is time of completion of reading. Therefore, if the reading was started at 17:09 but completed at 17:10, on the main screen, the NBP time is displayed as 17:09 but in the Tabular Trends, it is recorded as 17:10. Rather confusing, if you ask me

1. Counter-intuitive direction of cursor movement. When turning clockwise, cursor moves left to right, as expected, but, unexpectedly, the cursor moves bottom to top. Worse yet, in the help menus, the cursor moves top to bottom. This inconsistency means you'll have to look diligently at the screen to see which direction the cursor is moving.

2. Tendency to overshoot desired selection.

3. Frequent double injection of knob (knob pressed twice when single press desired).

4. Also, when pressing knob, knob sometimes inadvertently turned resulting in wrong selection.

The last 3 points may be just me. Poorly trained user or user with poor fine motor control.

1. ECG arrhythmia monitoring is pretty neat
