Abstract: A device is provided for cooling intra nasally the brain of a patient, in particular of a patient suffering from cardiovascular emergency. The device comprises a pressurized gas container for containing a gas or a mixture of gases, and at least one cannula with a lumen, a proximal opening and at least one distal opening. The cannula is for introduction into the patient's nasopharynx. Upon operation, gas expands adiabatically upon exiting from the at least one cannula, thereby cools and provides a coolant effect on the nasopharynx and inside the nasal cavity.

Abstract: A method, apparatus and computer program for defibrillation delivery decision comprising the steps of: a) Determining a shockable rhythm with a first algorithm, whereby said first algorithm is adapted to analyze an ECG signal in the presence of chest compression; b) Determining a shockable rhythm with a second algorithm, whereby said second algorithm is adapted to analyze an ECG in the absence of chest compression; c) Determining with a third algorithm if the patient is undergoing chest compression.

Abstract: The invention relates to a defibrillator with integrated means for chest compression feedback. The defibrillator is shaped and sized such as to be directly placeable on the patient's chest.

Abstract: The invention relates to a cardiac defibrillator used to treat a patient in cardio-circulatory arrest by a shock from a dosed biphasic discharge from a capacitor through an H-bridge comprising a high-voltage switch A, B, C or D in each of the limbs thereof. Said cardiac defibrillator is characterised in that each opposing polarity phase of the biphasic shock is controlled in two stages in such a way that, for each pair of switches associated with a phase, the first switch is switched on and remains on during the entire phase, while the second switch switches off in a staggered manner in relation to the first switch for a controlled amount of time in order to pass the current through the patient during said phase, the same process being carried out for the second phase with the other pair of switches. The invention is especially suitable for manufacturers of defibrillation appliances.

Abstract: A method for collecting and a device for sensing at least one electrophysiological signal, as well as to a system including at least one such device. The device for sensing at least one electrophysiological signal from a living subject subjected to at least one electromagnetic field, includes elements, such as electrodes, which are placed on the subject for the physical acquisition of at least one electrophysiological signal and at least elements for the pre-processing of the at least one sampled electrophysiological signal. The sensor device (1) is characterised in that it also includes additional elements (7, 8) for measuring or determining at least one characteristic of the electromagnetic environment at or close to the electrophysiological signal acquisition point(s) or zone(s) on the subject.

Abstract: A method of obtaining an electrocardiograph (ECG) of a patient located in a turbulent electromagnetic environment. The method includes recovering an ECG signal from a patient. The signal, including added noise, is recovered near the cardiac region as the differential signal resulting from signals delivered by two electrodes forming part of a first measurement loop. The signal further consists of simultaneously recovering from the patient a second measurement signal incorporating at least the noise, as a differential signal resulting from the signals delivered by two electrodes forming part of a second measurement loop distinct from the first measurement loop. Then, the second measurement signal is added or subtracted from the first noisy ECG signal, in real time. The second measurement signal is as a function of the polarity of the noise in the second signal relative to the noise in the first noisy ECG signal.
