Definitions
- the current invention relates to the field of medical anesthesia. More particularly it relates to the field of electronic monitoring of a patient undergoing anesthesia, especially for use during and after surgical operations.
- the invention more specifically relates to the user interface of the instrument used to monitor a patient's state of awareness.
- an instrument that provides information related to the patient's anesthetic state during surgery must have a small form factor.
- space available to the anesthesiologist or nurse anesthetist can be extremely limited.
- the instrument must further provide a simple means of control and a clear, concise, and intuitive display.
- the size restriction limits the size of the visual
- the simplified control requirement comes from the limited time that the user can allocate to operating the instrument.
- the user's time allocation also drives the requirement for a concise and intuitive information display.
- the typical user, an anesthesiologist or nurse anesthetist performs numerous tasks to assess the patient's clinical state and to modify the delivery of drugs necessary to properly manage the patient during surgery.
- For the instrument to be usable in this environment it must not be time consuming to configure and operate.
- the user For the instrument to be effective in this environment, the user must also be able to access and understand the displayed information within seconds. It is therefore an object of the current invention to provide a user interface for an electronic anesthesia monitoring instrument which conforms to the space requirements of the operating room while simultaneously providing simplicity and responsiveness of control and intuitiveness of the information displayed by the interface.
- the current display system optimizes use of screen area by presenting only mode appropriate information. In part it establishes this optimization by creation of a multifunction label area such that each label position may be used for multiple functions.
- the system also combines notifications of events with display of actions required to respond to those events. It further minimizes time and actions required to access any required functionality option.
- the Context Groups and their dynamic labeling also provide for highly flexible and adaptable user interaction sequencing.
- the system further provides immediate access to a small subset of functions of an immediate nature and minimizes the number of physical inputs, thereby providing ease of use along with lower cost.
- Figure 1 is a schematic depiction of the face of the display system.
- Figure 2 shows the mathematically logical display of awareness and burst suppression.
- Figure 3 portrays the intuitive display of awareness and an inverted burst suppression display.
- the preferred embodiment of the anesthesia monitoring instrument's user interface physical components consists of an approximately 6.5 inch diagonal VGA (640/480) resolution color (256) display with 12 front panel pushbuttons as shown in Figure 1.
- the 12 tactile pushbuttons are organized into 4 functional groups: Power 12, Menu/Navigation 14,
- the Dedicated 16, and Context 18 There is a single pushbutton 11 that performs Power-On/Standby control.
- the Menu/Navigation group 14 has 4 directional arrows 15 that are used to identify selections from a graphically presented drop-down (on the display screen) menu system.
- the Dedicated group 16 provides three buttons 17 giving direct access to functions of an immediate nature: controlling audible alarms 17A, declaring events 17B, and requesting hard copy 17C.
- the Context group 18 pushbuttons 19 are, through physical placement and labeling, associated with the display. Context sensitive labels, associated with the Context pushbuttons, define the action to be performed upon activation.
- the Context pushbuttons support the Context System that serves as the basis for the user interface design (see below).
- This functional grouping of pushbuttons and the associated Context System allows a minimal set of user inputs to support both immediate function access and a simple means of instrument configuration.
- the small number of user inputs improves physical access, while the Dedicated 16 and Context 18 groups minimize the time required to operate the instrument.
- a Context System served as the basis for the design of the user interface.
- This system is based on two concepts. The first concept is to organize the information presentation into pages that support the operational modes, allowing the optimization of the information displayed relative to the mode.
- the second concept is to dynamically reconfigure the context labels, and thereby the readily available user actions, based on the instrument or user context. Combining these concepts optimizes the use of the minimal display area, while still providing an informative display and the user's ready access to required functions.
- a context typically consists of display of context targets/labels, association of context pushbuttons with targets/labels, and possible context related display entities, e.g., menu items during menu context.
- the contexts is use are: Trend Page context; EEG Page context; Review Page context; Status Page context; Check Electrode context; Adjust Parameter context; Date/Time context; and Menu context.
- Each one of these contexts associates different choices with the context buttons depending on which context the display is in at the time.
- the anesthesia monitoring system to which the display system is connected generally has a plurality of modes of operation. In the current embodiment, these are: Startup; Calibration; Acquisition; and Review. Each mode of operation has associated with it one or more of the above listed contexts.
- modes When the user changes modes the associated mode page is presented and that page's context labels are displayed. For example, when EEG waveform page is displayed, context labels are presented that provide for amplitude and time formatting of the displayed waveforms. If the user then changes to Trend Review Mode, the amplitude and time labels are removed and the Trend Review context labels that provide for scrolling forward and backward through the trend are presented. Asynchronous events may cause new contexts to be added to or replace existing label context.
- the instrument continuously monitors electrode impedance. If an impedance measurement falls outside an acceptable range a 'check electrode' label context is displayed and actuation of the associated pushbutton changes to a page to one which identifies the offending electrode(s).
- the primary derived parameter of the instrument is a measure of the patient's level of consciousness or awareness.
- This derived parameter is displayed as a filled chart where the ordinate is the derived parameter and time is the abscissa. This displayed trend is the primary focus when a user directs attention to the instrument. To make interpretation of the displayed information intuitive the filled chart is color-coded.
- a surgical maintenance range can be defined by declaring upper and lower values of the derived consciousness parameter. The anesthesiologist guides the patient within this maintenance range to minimize delivered medication while maintaining an appropriate level of consciousness.
- the chart is colored: values falling within the maintenance range are- green, values outside the range are yellow-orange. Trend points are drawn white if there is insufficient information to properly update the derived parameter.
- Burst Suppression is an electro-encephalographic signature of a patient's brain state. At low levels of conscious the Electro-encephalographic signals exhibit periods of isoelectric behavior. These isoelectric periods end in a burst of electrical activity. The burst suppression parameter is a measure of the percentage of time spent in suppression (isoelectric) per minute.
- Figure 2 The standard plots of the level of consciousness and suppression parameters are shown In Figure 2. This is the mathematically logical manner of presentation. However, Figure 2 does not present the information in a clinically logical or intuitive manner. Higher levels of suppression reflect more time spent with isoelectric electro-encephalographic signals and thereby lower levels of consciousness. By inverting the sense of the Suppression graph and plotting it coincident with the Awareness parameter the 'grand' chart becomes significantly more clinically intuitive (see Figure 3). The Suppession trend is plotted in blue. At some level of suppression, the value of the Awareness parameter is zero, with the patient depth of consciousness then primarily related to the high levels of suppress electroencephalograph signals. Figure 3 represents the trends combined into a single color code chart.
