Abstract: A device for practicing mask ventilation, comprising a first passage and a second passage. The first passage is designed to provide communication between a source of air and the interior of a patient mask. The patient mask is designed for placement over a person's mouth and/or nose. The second passage is designed to provide communication between the air source and a back pressure means. The back pressure means is adapted to simulate the resistance of a human airway. The device can also comprise a third passage designed to provide communication between a breathing person and the surroundings. The passages may be formed in one integrated adapter to be placed between a patient valve and the mask.

Abstract: Medical patient simulator comprising a torso (2) that contains an artificial lung (6), a chest skin (3) and means (8, 9) for pulling the chest skin (3) downward in an area corresponding with an area where such retractions occur on a human being. The simulator also provides for changes in the compliance of the lung (6). The lung (6) is situated between two plates (5, 7), the spacing of which can be adjusted. The torso (2) has one actuator (23, 24) on each side of the back to simulate muscular activity. It includes a system for control of pneumatic functions by measuring a representative pressure for each actuator and stopping the filling when a pre-set pressure is reached. It also includes a head with one or more air cushions in a fontanelle area on the head, which may be filled with air to simulate an increased pressure in the brain.

Abstract: A base headboard for supporting the back of an injured person's head has an elongated slot with teeth racks disposed on either side of the injured person's head. The headboard also comprises straps for attaching to a spine board. Two side head blocks are removably attached to the headboard using plunger-type locks that engage an elongated slot on each side of a center portion of the headboard. Each lock is engaged to a slot of the headboard through a separate elongated slot in the corresponding head block. Advantageously, a head block may be adjusted by moving the engagement of the lock along each independent slot in the headboard and head block, respectively. In addition, a head block may be rotated around its lock.

Abstract: A system is provided for evaluating the probability that the outcome of an immediately following defibrillator shock will result in return of spontaneous circulation (ROSC) and for providing a decision support signal based thereon. The system includes electrodes and sensors, a module for measuring CPR and ECG related data from the electrodes and sensors, the ECG related data being measured and/or stored as ECG segments, an analysis unit connected with the module and adapted to calculate a property vector characterizing the condition of the heart from the ECG segments. The analysis unit is further adapted to calculate a probability indicator representing the probability that the outcome of an immediately following defibrillator shock will result in ROSC based on the property vector. The analysis unit is also adapted to generate a decision support signal relating to further treatment based on the property vector and/or the calculated probability indicator.

The side edges of the cover may include at least one fastening device for straps for holding the cover and the mask tight against a patient's face, where the fastening device(s) may be hook-shaped.

Abstract: A system for reducing signal disturbances in ECG, which disturbances are caused by cardio-pulmonary resuscitation (CPR). The system includes a measuring device for measuring one or more signals derived from parameters such as compression depth, lung inflation etc. as a result of CPR. The parameter signals form one or more reference signals that correlate with the signal disturbances. One or more adaptive filters filter the signals out from the signal that constitutes the ECG signals so as to remove disturbances caused by CPR.

Abstract: A resuscitation device for providing a barrier between a rescuer and a patient requiring mouth-to-mouth resuscitation. This resuscitation device includes an inflatable portion which when inflated extends in the breathing direction between the rescuer and the patient so as to be placed around at least one breathing organ of the victim. An inflation member receives airflow from the rescuer to inflate the inflatable portion. In this resuscitation device, a valve assembly permits airflow from the rescuer to the patient and diverts the exhalation and body fluids of the patient from reaching the rescuer. An additional barrier member can also be provided for shielding the rescuer from the patient.
