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.
