Simply attach the sensor kit to your manikin, download the free mobile apps in your app store and receive detailed CPR feedback in real-time using the app on your mobile device. Even a class of six students can be monitored easily via the Instructor mobile App powered by heartisense®. The CPR app provides feedback for:Compression (depth, recoil, and rate)Breath (volume)Hands-off time in real-timeFeedback and evaluation meet the standard of the latest guidelines of the American Heart Association (AHA) and the European Resuscitation Council (ERC).The CPR app to be used with the CPR Upgrade Kit come in two versions: a Student App and an Instructor App fitting the needs of each user.Overview of the CPR App features:Offers overall scoring and intuitive point of improvement during CPRDirect (real-time) and summative CPR feedback for studentsInstructor view can monitor up to 6 manikins at a timeSaved student results for reviewExport or share students result/certificate as a PDF fileInstructor can use CPR analysis for detailed debriefingEasily switch from conventional CPR training to ''compression only'' CPR settingsStable connection thanks to reliable Bluetooth connectionThe hardware of the Upgrade Kit for all BASICBilly Basic Life Support (BLS) is easy to install and the apps are available for free to download in your Apple or Google app store. The Upgrade Kit includes a sensor that enables the manikin to send compression and breath data to the mobile device in real time. If you already own a BASICBilly BLS, you can easily upgrade it to the BASICBilly+ BLS and CPR manikin installing the Upgrade Kit and use the additional features right away.Demonstration model for showing how refrigerators and electrical compression heat pumps work.Consisting of compressor with drive motor, vaporizer, expansion valve, and condenser. May be used as an air-water or water-water heat pump. Includes wattmeter -- for recording the operation time, the mains voltage, instantaneous power input, electrical work -- and two thermometers for measuring the temperatures in the two reservoirs.The components are connected in a closed system by copper pipes and mounted on a base board, and the clear layout makes it possible to directly relate the sequence of changes of state to the cyclic operation of the heat pump. Evaporator and condenser are constructed as copper tubing spirals and each of them is submerged in water filled containers serving as heat reservoirs for determining the heat absorbed or emitted. Two large manometers display the pressure ratios of the coolant in both heat exchangers. Two observation windows are provided for observing the state of aggregation of the refrigerant after the evaporator and after the condenser. A protective overpressure switch disconnects the compressor motor from the circuit when overpressure reaches 15 bars.
