Drager Introduces Zeus Infinity Empowered
Drägerwerk AG has just announced the release of a new anesthesia machine, called Dräger Zeus Infinity Empowered (IE), that features a combination of options to conduct either inhalational or intravenous based techniques, or both at the same time. Furthermore, for those who are looking on some savings when it comes to delivery of desflurane (and to a lesser degree isoflurane or maybe halothane), the machine offers a closed circuit system design. And as far as blower is concerned, the machine is based on a popular Dräger Evita Infinity V500 ventilator.
Dräger Zeus IE provides all options of anaesthetic techniques: From inhalation to (total) intravenous anaesthesia – all these applications can be utilised in the closed circuit system of the Dräger Zeus IE. Thanks to its closed circuit system, the device consumes even less gas than in the low flow or minimal flow mode – and that fully automated. In addition to the manually controlled fresh gas dosing also oxygen, carrier gas and volatile anaesthetics can be controlled automatically and targeted accurately (TCA = target controlled anaesthesia). The device also compensates potential leakages automatically. The haemodynamic monitoring, which can be integrated as an option, is operated via the high-definition 17" screen of the medical cockpit, the Infinity C500. Via this cockpit, the clinician can also control the ventilation parameters. By this, all OR information is fed to the integrated patient data management system, thus also simplifying the work procedures.Even in the operating room, adult patients, children and neonates benefit from the differentiated ventilation in intensive care quality. The turbine allows for spontaneous breathing at any time, which can shorten the recovery time for the patient. Up to four syringe pumps (Fresenius Module DPS), which can be controlled via the system, and the integrated medication database, which includes pre-configured default values and dosing limits for numerous pharmaceuticals, ensure an optimal intravenous anaesthesia.
In the operating room and the intensive care unit, nomenclatures and principles of use should be identical. The concept of the IACS, into which the Dräger Zeus IE can be integrated, provides exactly this. The user interface, nomenclature and parts of the hardware employed correspond to those of other IACS components, such as the Dräger Evita Infinity V500 ventilator. USB ports for storing and loading device and profile settings enable the clinician to transmit settings within a very short period of time to any number of Zeus IE systems. The uniform, intuitive user interface and a more efficient service concept are intended to support the operator.

SmartPilot View: An Anesthesiologist's Flight Simulator
Drägerwerk AG is releasing a new software package to help manage and predict the progress of intraoperative anesthesia (general and MAC), including modeling drug interactions and taking into account the unique nature of individual patients' physiology. Looks like the software is designed to model narcs, barbs and benzos, but not inhalational agents:
Dräger SmartPilot View is an assistance system, which supports anaesthetists in making decisions, but does not make decisions for them. The software is based on pharmacokinetic and pharmacodynamic patient models, which calculate and visualise the effects of analgesics (opioides) and sedatives (hypnotics). Up to now, it was not possible to visualise the interactions between these two substance groups and to show the anaesthetist at which stage of the anaesthesia the patient is and will be. In addition, the SmartPilot View gives an answer to the question: "What would happen if …". The software provides a preview of the calculated course – before the pharmaceuticals are applied to the patient. The program also displays the effects of the relaxants included in the anaesthesia with the corresponding time of occurrence.SmartPilot View displays all information required for controlling the anaesthesia at a glance: In addition to the measured parameters, for example pulse rate and blood pressure, the software also displays the chronological sequence of the applied pharmaceuticals and their effects in a two-dimensional representation. The idea of this representation is based on the cockpit of an aeroplane. This means that the anaesthetist sees precisely – like a pilot – at which calculated stage of the anaesthesia the patient is just now and what the prediction for the immediate future will be.
SmartPilot View can support anaesthetists in previously detecting and preventing under dosing and overdosing – even if the anaesthesia is initiated intravenously, but then continued with volatile agents. In this scenario it would not even make a difference if the anaesthesia had been initiated manually via an injection. Event markers such as intubation, incision or repositioning enable the anaesthetist to document important events during the course of the anaesthesia...
In clinical routine, the SmartPilot View operates with Dräger anaesthesia systems (Primus/Primus IE, Zeus/ZeusIE) and Dräger monitoring systems (Infinity Delta, Infinity C700 for IT and Infinity Explorer). In combination with specified syringe pumps (B. Braun Space or Dräger IVenus), the anaesthetist can use the full functionality of the software.

Thermahelm Motorcycle Helmet Cools Head Upon Impact
A University of Edinburgh PhD student from the United Kingdom has created a motorcycle helmet that uses an endothermic chemical reaction to self-cool upon impact. The company, Termahelm, will soon offer the ability to either buy a helmet directly from them or retrofit your current helmet with the cooling technology.
The website is misleading on the benefit of this technology in that it points to a multitude of studies investigating systemic hypothermia in the treatment of traumatic brain injury (TBI) where the entire patient is cooled for an extended period of time. That's not what the helmet is doing and even if it were, whether or not this actually helps seems to still be an open question (see review). Also, the premise of the idea rests upon two assumptions: one, that prophylactic local hypothermia (icin' the noggin') leads to better severe head trauma outcomes. And two, that applying this therapy immediately, even before an ambulance arrives, has a clinical benefit.
That being said, it seems like a neat idea and leaves us with the obvious question: Can you activate it while riding on a hot summer day?

Hemolung, a Respiratory Dialysis Device, to Start Clinical Trials
Ventilators, though staples of modern critical care, have serious drawbacks for both patient safety and comfort, and flexibility issues for clinicians. The Pittsburgh Post-Gazette is reporting that a considerably less intrusive system from a local company called ALung Technologies is about to begin clinical trials in India and Europe. The Hemolung is designed to perform respiratory gas exchange via a catheter inserted into the femoral or jugular vein. The process is essentially similar to traditional extracorporeal membrane oxygenation, but thanks to new technology, the device is touted to be safer and easier on the patient.
Here's what an article in Pulmonary Reviews in Feb 2009 detailed about the system:
The Hemolung is a small, cylindrical, veno-venous extracorporeal CO2 removal device, said Dr. Batchinsky, a research scientist at the US Army Institute of Surgical Research, Fort Sam Houston, Texas. “It provides roughly 30% to 40% CO2 removal at blood flows in the range of 400 to 500 mL/min,” which, in this ovine study, translated into a CO2 removal of 66 mL/min. The Hemolung requires a prime volume of 300 mL and minimal heparinization.The military is investigating the artificial lung with the goal of delivering new critical care technology to the battlefield, Dr. Batchinsky indicated. “The Hemolung may be beneficial during the transport of combat casualties with acute lung injury back from the front lines to the Continental US. It is a ‘set it and forget it’–type device that is easy to use and operate.” Additional potential applications include use as a bridge prior to lung transplantation and as an intermittent therapy for ARDS and COPD.
ALung's expectations of benefits for patients:
Elimination of sedation allows the patient to stay alert, eat and communicate.
Elimination of ventilator associated pneumonia eliminates dangerous complications, and should reduce cost of care and length of stay in the ICU.
Avoidance of intubation allows the patient to eat, speak and prevents tracheal injury and sinus infection.
Reduction in weaning failure should reduce length of stay in the ICU and potential mortality.
Reduction in tracheostomies will reduce an invasive surgical procedure to the larynx.
Reduced lung injury may reduce the incidence of death.

Infinity M540 from Draeger Makes Hospital Workflow and Patient Data Oh So So Smooth
Here's another piece of news about medical gadgetry released at the ongoing Medica 2009. The Infinity M540 from Drägerwerk AG & Co. (aka Dräger) is designed to provide portability and full functionality of a stationary vitals signs monitor:
The Dräger Infinity M540 measures and saves patient vital signs data, including 12-lead ECG and etCO2 values. For transport, the hospital staff can release the M540 from its docking station using one hand. The monitor continues to display and record vital data without interruption. As soon as the M540 is reconnected to a docking station – whether at its previous location or on a different ward – it automatically backfills the data recorded on transport into the Medical Cockpit, which is the central control and viewing unit of the Infinity Acute Care System.This way, trends and events from the patient's current hospital stay are accessible to the clinician even after transport. When the Infinity M540 is used in combination with an Infinity C700 or C500 Medical Cockpit, relevant monitoring parameters are available. "In view of increasingly complex clinical scenarios, having comprehensive patient information is becoming a key factor in modern patient care," says Prof. Dr. Jürgen Peters, Director of the Clinic for Anesthesiology and Intensive Care at Essen University Hospital. The clinic was the first facility in the world to install Infinity M540 monitors.
To support hospital workflow, a compact monitor design and simple operation are also required. "In the daily clinical routine, it is important for staff and patients that devices are simple to operate," explains Jürgen Peters. "The less we have to concentrate on the technology, the more we can focus on the patients."
The slim, rectangular design of the M540 makes it possible to hold the patient monitor with just one hand. The color display fills almost the entire surface area of the monitor, so multiple vital signs parameters can be viewed at a glance despite the compact size of the device.
When the monitor is turned 180 degrees, the display rotates automatically so information is immediately readable again (auto-flip technology). This enables the monitor to be positioned on either side of the patient, as required for proper orientation of the cable connectors.
When docked, the M540 can automatically adopt the settings from the Medical Cockpit to which it is connected. This allows each ward to immediately display the parameters relevant to the ward without having to reprogram the device. As menus, nomenclature, function keys and display are similar to other Dräger components, the M540 can require only a minimal amount of training. This standardization also helps to avoid errors.

SafetyNet Monitoring System Keeps an Eye on Wards of Patients
Masimo is releasing a new version of the firm's popular SafetyNet™ remote monitoring system. According to the company, the system can provide continuous pulse oximetry readings from up to eighty patients on four separate hospital floors. The technology aims to decrease respiratory-related adverse events in a high risk population, such as post-surgical patients on the general care floor, patients with obstructive sleep apnea, and those who are on narcotic analgesics. Using internal pagers or interfacing with other messaging systems, the central server can notify clinicians if a patient requires prompt attention.
The Masimo Patient SafetyNet remote monitoring and clinician notification system combines the gold standard performance of Masimo SET® pulse oximetry with optional Oridion Microstream® end tidal CO2-based respiration rate monitoring at the point of care and wireless clinician notification via pager to provide an unmatched level of patient safety on general care floors. The system uses IEEE industry standards for connectivity—allowing for more efficient sharing of data across a hospital's IT platforms and the option of full integration into a hospital's existing IT infrastructure, providing a lower overall cost of ownership and improved financial benefits.The new Patient SafetyNet system is already having a big impact on both nurses and post-surgical patients for two hospitals involved in limited market release testing. Marilyn Nemerever, R.N., director of Acute Care at Swedish Medical Center in Seattle, where the new system is being used to monitor patients in three separate post-surgical units at three different hospitals from a single central monitoring station, stated "We love it. ICU beds are in high demand these days and Patient SafetyNet allows us to more closely monitor post-surgical patients in our med-surg units, so we can use our ICU resources more appropriately. Our nurses now have the piece of mind that comes with knowing that Patient SafetyNet is helping watch over their patients if and when they cannot. And our patients are having better outcomes because we can see, as well as respond to changes earlier."
Clinicians at Dartmouth-Hitchcock Medical Center, who found that Patient SafetyNet reduced rescue activations by 65% and ICU transfers by 48%—while in some patients where ICU transfer was avoided, length of stay was also reduced from 5.8 to 3.6 days with an associated cost of care reduction of 30%, have also embraced the capabilities of the new Patient SafetyNet system. George T. Blike, M.D., Medical Director of Patient Safety at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire, stated; "The new system enhancements allow us to see real-time numerics for each patient at a glance, while the ability to monitor more patients on a single server will enable us to deploy the system across more care areas than before to reduce overall costs of implementation."

Fighting Catheter Associated Urinary Tract Infections with a Better Designed Foley Tray
Catheter associated urinary tract infections (CAUTI) account for up to 40% of hospital-acquired infections. Patients who get urinary tract infections during their hospitalization often find themselves staying for longer periods of time than necessary at a high cost to the hospital, especially given that Medicare and Medicaid often don't provide additional reimbursement for CAUTI.
Reducing these infections generally involves making sure the catheter was needed in the first place, ensuring that good sterile technique is used during placement, keeping the duration of catheterization as short as possible, and keeping the catheter properly secured to the patient's leg. In an effort to reduce CAUTI, Medline Industries, developed a new Foley catheter tray that attempts to be more intuitive, better designed, and with more directions than current trays. It's only one level deep, has clear labeling guiding the practitioner step by step, and contains clearer instructions for insertion of the catheter.
It would be nice to see some data on whether the new tray's design actually promotes better aseptic technique, but for those who've used a Foley tray before and experienced the often unwieldy and unorganized contents, any step toward a better design seems to be a good one.
From the press release:
"Even though clinicians do their best to practice good aseptic techniques, infections happen due to poor technique or because the catheter is left in too long," said Alecia Cooper, RN, MBA, CNOR, Sr. Vice President, Clinical Services for Medline.In reengineering the Foley catheter tray, Medline focused on incorporating tools and tips for improving the insertion process to help minimize CAUTI risk. For example, the tray features an innovative one-layer design that guides the clinician through the process of placing the catheter while ensuring aseptic technique. (Typical catheter trays consist of two layers, requiring additional room to perform the procedure, increasing the risk of breaking the sterile field.) Visual reminders and cues are strategically placed to guide the clinician through the correct procedure.
"The new tray design, instructions, arrangement, and labeled components are designed to help make it hard for the worker to do the wrong thing," said Sue MacInnes, Chief Marketing Officer for Medline.

Resposable Oxymeter Sensor Aims to Cut Costs, Waste
Masimo's Rainbow Resposable Sensor System has been approved by the FDA. The sensor, designed to be used with company's Masimo Rainbow® SET Pulse CO-Oximetry system that can "noninvasively measure blood constituents and fluid responsiveness that previously required invasive procedures," can either be washed for multiple patient use, or be thrown out once it has seen its days.
The new sensor system provides continuous and noninvasive measurements of hemoglobin (SpHb™), oxygen content (SpOC™), PVI™ for fluid responsiveness, and methemoglobin (SpMet®), in addition to oxygen saturation (SpO2), perfusion index, and pulse rate—at savings of about 50% compared to the existing single patient use adhesive Rainbow sensor.The Rainbow Resposable Sensor System combines the best features of Masimo LNOP®, LNCS®, and Rainbow® sensors into an innovative two-piece design that includes a reusable sensor—enabling the portion that connects to the patient cable to be used on multiple patients - while the adhesive disposable sensor that attaches directly to the patient's finger is used on only one patient. This dramatically minimizes waste, enabling hospitals to reduce their costs safely, and effectively fulfill their 'green' initiatives.
The reusable portion of the two-piece system provides multi-patient use for cost-effectiveness, while the flexible cable design maximizes patient comfort, and enables easy, one-step cleaning. The snap-in-place connector design allows easy connection and reconnection to the same patient—and reuse on the next patient. The single-use disposable portion of system features an adhesive that keeps emitter and detector positions stable against the skin to assure the best in Masimo SET and Rainbow SET measurement performance. The design maximizes fit and comfort for the patient, while the protective covering minimizes contact with patient to reduce cross contamination risk.

VasoNova Gets to The Heart of The Matter
Placement of a peripherally inserted central line so its tip is located at the lower third of the superior vena cava, just prior to the right atrium, is always a guessing game. Nowadays, the only way to confirm position of the line is to do an X-ray of the chest. VasoNova out of Sunnyvale, California wants to change the rules of the game. The company is introducing a device that uses Doppler ultrasound to monitor direction of blood flow and ECG to help position the catheter at the optimal location.
The VasoNova VPS consists of several components: the VPS Stylet, the VPS Power Injectable PICC catheter and the VPS Console.The VPS Stylet contains two sensors at its tip: a Doppler Ultrasound sensor and an intravascular ECG lead. Due to the ingenuity of our R&D group, VasoNova was able to miniaturize the two sensors and construct a highly technical and flexible stylet that can fit into the lumen of the VPS Power Injectable PICC line with comparable dimensions to other market available PICC lines12. Once the VPS stylet is loaded into the VPS catheter and connected to the VPS console per the Instruction for Use, the VPS Stylet is able to detect the patient's physiological data, such as blood flow characteristics and ECG waveform.
From the point of insertion, patient data are sent to the VPS console for analysis. Using the highly advanced hardware and complex algorithm, the VPS console analyzes multiple vectors derived from these data and determines the location of the catheter tip while it is advanced through the patient's vasculature. Using the data gathered by the sensors and analysis done by the console, the VasoNova VPS console displays visual indicators. These indicators guide the clinician in real-time as the catheter is advanced through the vasculature:
The green arrow indicates the catheter tip is moving with the blood flow towards the heart, as appropriate.
The orange "do-not-enter" sign indicates the catheter is moving against blood flow, such as into the internal jugular vein and away from the heart, or has passed the lower third of the SVC and going into the right atrium.
The yellow triangle indicates there is not enough information available, which may occur if the catheter tip is against the vessel wall.
The blue bull's eye indicates the tip has arrived in the lower 1/3 of the SVC or at the caval-atrial junction.
