Procedure for the generation of a reflex tear secretion, which comprises the chemical stimulation of the cornea of the eye of a subject by applying a controlled jet of a gas with a high CO.sub.2 content, of at least 80% of CO.sub.2. Compact device (1,1′) for the generation of a reflex tear secretion, comprising a gas source (7) in the form of a disposable type cartridge containing a pressurized gas with a composition of at least 80% of CO.sub.2; and a pneumatic circuit connecting an outlet mouth of said gas source (7) with a gas outlet nozzle (3) of the device (1,1′), the circuit comprising pressure regulation means (8) and flow rate (17) regulation means suitable for ejecting puffs of gas through the outlet nozzle (3) at a predetermined pressure and flow rates.

The disclosure is directed to an apparatus and a method for improving manual ventilation and resuscitation by monitoring ventilation parameters and assisting resuscitation. The apparatus includes a gas flow sensor configured to measure a flow rate of exhaled gas of a subject. The apparatus is configured to receive an ideal body weight or a predicated body weight of the subject and calculate a first tidal volume range based on the ideal body weight or the predicated body weight of the subject. The apparatus is also configured to obtain an exhaled tidal volume of the subject based on the measured flow rate and determine whether the exhaled tidal volume is within the first tidal volume range. When it is determined that the exhaled tidal volume is not within the first tidal volume range, the apparatus is further configured to perform a first tidal volume warning.

A CPR apparatus includes a chest compression unit and a means for mounting the chest compression unit on a patient. The chest compression unit includes a plunger disposed in a housing. At its one end extending from the housing the plunger has a compression member. The plunger is driven in a reciprocating manner by a reversible electromotor via a mechanism for translating rotational motion to linear motion or by a linear induction electromotor. The chest compression unit includes an electromotor control unit including a microprocessor, a first monitor for monitoring the position of the plunger in respect of the housing and a second monitor for monitoring the position of the plunger in respect of the mechanism for translating rotational motion to linear motion or the rotor of the linear induction electromotor. The monitored positions are communicated to the electromotor control unit. Also disclosed is a corresponding CPR method.

Embodiments of the present invention include a system having at least one sensor configured to monitor a muscle oxygen saturation (SmO2) level of a patient who is undergoing cardiac arrest and to generate a signal representing SmO2 level; a user interface device; a processor communicably coupled to the user interface device, the processor configured to cause the user interface device to present an array of two or more possible nodes of a clinical decision support tree, wherein at least one of the nodes indicates cardiopulmonary resuscitation (CPR) treatment of the patient with no ventilation, and wherein at least another of the nodes indicates CPR treatment of the patient with active ventilation; determine which of the two or more possible nodes should be emphasized based on the SmO2 level; and update the array of the two or more possible nodes based on the determination.

Method of treating an individual following a period of ischemia are provided. The methods include administering inhaled agents postconditioning to the individual and optionally simultaneously performing cardiopulmonary resuscitation. The inhaled agents include at least one noble gas.

An external defibrillator system is provided. The system includes: a graphical display; one or more sensors for obtaining data regarding chest compressions performed on a patient; and a controller configured to display on the graphical display numeric values for depth and/or rate of the chest compressions based upon the data from the one or more sensors. A method for using an external defibrillator including the steps of: obtaining data regarding chest compressions performed on a patient; and displaying on a graphical display screen of the defibrillator numeric values for depth and/or rate of the chest compressions based upon the data is also provided.

A feedback device for an acute care provider includes: at least one motion sensor; a haptic output component for providing feedback having a varying haptic pattern to the acute care provider regarding performance of a resuscitation activity; and a controller. The controller can be configured to receive and process a signal representative of performance of the resuscitation activity from the at least one motion sensor, compare the acute care provider's performance of the resuscitation activity to a target performance of the resuscitation activity, and cause the haptic output component to provide haptic feedback to the acute care provider by changing the haptic pattern based, at least in part, on the signal from the at least one motion sensor and the comparison of the acute care provider's performance to the target performance of the resuscitation activity. The device can be adapted to be wrist-worn by the acute care provider.
