Almost like a second skin

Without any doubt, one of the most brilliant inventions made by Swisstom’s pioneers is the electrode vest’s structured fabric which ensures skin-friendliness, optimum wearing comfort as well as intuitive handling and nursing during daily hospital routine. A specially developed fluid operates as a bond between the patient’s skin and the electrode vest – almost like a second skin. Due to this mechanism and hygienic reasons we conceptualized the vest as a disposable medical product.

Real-time monitoring – easy and skin friendly

Swisstom BB2 was especially developed to continuously monitor lung function of ICU patients undergoing mechanical ventilation. To do this, a belt-like disposable textile patient interface, the SensorBelt, is fastened to the patient‘s thorax. Its integrated sensors measure the respiration in different lung regions, constantly con-verting the generated data into images. The SensorBelt´s core contains 32 miniaturized active electrodes, the EIT-Chips, which all report to and are controlled by the SensorBeltConnector located on the patient´s sternum.

The reusable SensorBeltConnector is much more than just a simple connector. It acts as Swisstom BB2´s brain using cutting-edge electronics and sensors inside. Among these sensors is also a 3D accelerometer which tracks the patient´s body position. Information about this position and the measurement quality of each electrode are sent together with the EIT signals directly to the Tomographic-ImageCreation module within the bedside monitor. There the images are created and displayed in real-time on the graphical user interface.

Swisstom´s disposable single-patient-use SensorBelt respects the essential needs of patients and caregivers alike.

The appealing green vest carrying the SensorBelt was designed together with nursing specialists such that it can be applied comfortably to a lying passive patient by one caregiver alone. Due to its highly flexible materials the application procedure, which takes less than one minute, closely resembles that of changing linen. The stretchable minimalistic vest feels like a second skin carrying all marker lines needed for its placement. The skin friendly vest holds the electrical interface in place even when patients are turned, moved or regain activity.

The oblique design makes the SensorBelt follow the movement of the ribs and thus does not restrict breathing as this would be highly undesirable in patients already suffering from respiratory insufficiency. No individual electrodes need to be placed on the patient, instead they are all integrated within the SensorBelt´s soft structure. While the textile silver sensors face the patient´s skin, the 3D spacer cushion underneath them allows the skin to breathe even under maximal compression and yet its adaptive nature ensures electrode coupling also in anatomically problematic areas.

The unique ingredients of the foamy Contact-Agent not only ensure an optimal electrical connection between SensorBelt and patient skin, it also protects it. This allows the belt to be worn for up to 72 hours. The ergonomic design of the matchbox-sized non-disposable SensorBeltConnector with just a single cable running to the monitor eliminates many potential sources of handling errors or accidents.

The touch user interface combines perfect usability with highest design quality. Its interaction is intuitive. The user friendly way clinically relevant information is presented facilitates decision making.

The interface is divided into three main sections which overlap on the screen. The selected view displays detailed information on a large area. At the same time, the other two sections are shown in a compact view. They display any relevant data in reduced form so that it is still possible to keep an overview of the entire situation. A new view can be selected by simply tapping it: The area expands, moving the previous view to the background. This clear structure allows for a fast operation of Swisstom BB2 even within the stressful intensive care environment. The unambiguous interface structure ensures a maximum of usability.

ScoutView (topographic view)
The ScoutView provides the user with an overview of the patient‘s general data and indicators of monitoring quality and body position. Once a belt of appropriate size for an individual patient has been determined, all the user has to do is enter height, weight and gender using the number picker of the ScoutView. From these inputs Swisstom BB2 automatically selects reference contours of thorax, lungs and heart that best match the individual patient. The EIT system then transmits the breathing lungs directly into these contours on the screen.

VentView (ventilation view)
The VentView displays continuously and in real-time the amount of ventilation within the lungs during breathing. Taking the lungs´ contours into account the user can immediately recognize lung zones in which ventilation is reduced or even absent.

LuFuView (lung function view)
The parameters shown in the LuFuView are calculated and updated with each new breath. The unique way lung function indices are calculated and displayed allows the user to visually identify patterns of health or disease. Next to their spatial distribution, the frequency of each parameter expression is made available as an intuitive histogram. Swisstom BB2‘s interaction and design concept provides the user with a clear picture of complex information.

VentViewTM: Shows the distribution of air within the lungs during breathing just like a movie. This information on regional ventilation is brought to you continuously and in real-time.
The clear and reduced appearance of the award-winning touch user interface facilitates decision making in stressful environments. It is divided into three main views which overlap on the screen. The selected view show detailed information on a large area. At the same time, the other two sections are shown in their compact form now displaying key information only. This way it is still possible to keep an overview of the entire situation. A new view can be selected by simply tapping it: The area expands, moving the previous view to the background. This clear structure allows for a fast operation of the device even within the intensive care or emergency environment.

The ScoutViewTM shown on the top in its compact form provides the user with indicators for skin contact, signal quality and for the patient´s body position.

The VentViewTM lets the users watch the lungs breathe by displaying continuously the distribution of air within the lungs during breathing. The expected location of the right and left lungs are depicted by their respective contours.

LufuView_V10_zz

LuFuViewTM: Stretch images show the impact of breathing on the local lung tissue. Both, histograms and images are updated with every breath.
Tidal EIT images refer to the changes in regional impedance values during one breathing cycle. During a breath, the lung tissue expands to receive the inhaled tidal volume. Some areas within the lungs receive large amounts of air during tidal breathing, others very little to no air. Regions with large stretch-related changes are shown in violet colors. The ten-part bar chart represents the relative contribution of each one of these stretch categories to the total tidal volume.

The parameter stretch or more precisely, “relative tidal stretch” shows you where and how the lungs are stretched during tidal breathing. It is a hypothetical concept based on the assumption that impedance changes are brought about by tissue expansion or stretch. As these changes occur during a single breath they are considered to result from the impact a tidal volume has on the mechanical and thus electrical properties of the surrounding lung tissue. Thus, the stretch images and histograms let you review the physical impact of the breaths you deliver.

To see what really matters switch to the Silent SpacesTM.

Silent Spaces

You finally see what really matters!

GB_2ST800-106_UserInterfaceExplained_Rev000-3Silent SpacesTM are areas within the lungs that receive neither much air nor much attention in other EIT images. As they represent complication-prone lung zones a special LuFuViewTM has been dedicated to them. The ease of use and visual clarity of the Silent SpacesTM support decision making at the bedside.

LuFuView_2_V10_zz

Silent SpacesTM expose those lung areas that do not breathe as expected while the centre of ventilation summarizes the lung´s entire ventilation in one single point.
Silent SpacesTM are derived from the smallest of the afore-mentioned stretch categories and divided into two groups: dependent and non-dependent Silent SpacesTM. If located in dependent lung zones Silent SpacesTM are likely to represent closed, collapsed, or fluid filled lung areas. If, however, located in the non-dependent lungs these areas are either distended or even overdistended.

Dependent in the context of these EIT image means located physically below, while non-dependent means located above the “ventilation horizon” shown as a horizontal reference line running right through the centre of ventilation, the depictive summary of the lungs´ entire ventilation in one single point.
The value attributed to the Silent SpacesTM is the relative number of pixels located either below or above the ventilation horizon and expressed as percent of the total number of pixels within the lung contour. Silent SpacesTM are calculated breath-by-breath and change with PEEP, recruitment, body position etc.

Therapeutic interventions should aim at minimizing Silent SpacesTM.

Regional lung function measurement by EIT clearly holds the potential to improve mechanical ventilation in general. Particularly, lung overdistention and lung collapse can be monitored [1] and used to eventually optimize PEEP [2]. EIT-guided ventilation results in improved respiratory mechanics, improved gas exchange, and reduced histologic evidence of ventilator-induced lung injury in an animal model [3]. Thus, EIT can be expected to reduce ventilator-induced lung injury in patients and to save ventilator days. This will result in an expected payback for a Swisstom BB2 of less than one year.

For nurses and physicians alike clinical usability is of the essence [4]. This is especially true for the patient interface as well as for the graphical user interface. Next to the unique SensorBelt, Swisstom BB2´s novel approach to presenting EIT information facilitates its interpretation. Pulmonary function indices are shown in the clinical context of the patient´s position and the contours of thorax, lungs and heart.

The touch user interface stands out from comparable medical interfaces, making its operation both, joyful and efficient. That way, caregivers can take timely and targeted actions to address changing lung conditions. Despite its clarity, the interface has a friendly and positive appeal, supporting communication between doctors, caregivers, patients and their families.
