A capnograph system may be used together with a ventilation system for a patient. The capnograph system may include a capnography module with a carbon dioxide detector, which may generate a carbon dioxide signal responsive to an amount of carbon dioxide detected within an air path of the ventilation system. A monitoring circuit may further detect a pressure within the air path. A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.

A cardiopulmonary resuscitation (CPR) training valve assembly well-suited for use with a CPR training mask or CPR mask. In one embodiment, the assembly includes a first housing member, a second housing member, and an air filter. The first housing member may be a tubular structure having a proximal end and a distal end, the proximal end being dimensioned for insertion into a user's mouth. The second housing member may be a tubular structure having a proximal end and a distal end, the distal end being dimensioned for insertion into, for example, a port of a CPR training mask. The second housing member and the first housing member may be repeatedly coupled to and uncoupled from one another. The air filter is disposed within one of the first and second housing members and is positioned to be removable therefrom when the first and second housing members are uncoupled from one another.

An artificial respiration apparatus for first aid is provided, and relates to the field of medical first-aid supplies. The artificial respiration apparatus comprises an adhesive film, wherein a fixing block is provided on an upper end of the adhesive film; a first adhesive strip is provided on a lower end of the adhesive film; a second adhesive strip is also provided on the lower end of the adhesive film; and a blowing device is inserted in the fixing block. An intraoral ventilation pipe is inserted into the mouth of a person to be rescued, then the adhesive film is applied to the mouth and nose of the person to be rescued, and finally air is blown into a blowing port such that the blown air enters the body of the person to be rescued through a ventilation pipe, and the intraoral ventilation pipe.

Described herein are various embodiments of a broad spectrum optical device, system and method for monitoring blood-borne chromophores. In one embodiment, a system comprises a broad-spectrum light source to probe multiple blood-borne chromophores associated with a physiological condition; a spectrometer operable to acquire an optical signal resulting from the broad-spectrum illumination; and a digital data processor operable to process the broad-spectrum response to at least partially spectrally resolve respective spectral responses to output a health-related indicator.

A rescue tube comprising a tube having a first and second end, a one-way valve and a ported double swivel elbow; wherein the one-way valve and ported double swivel elbow are connected to one another, and the one-way valve is attached to the tube.

A CPR training device is disclosed comprising a first member including a mouthpiece portion and a first engaging portion, a second member including an output portion and a second engaging portion, and an air passageway. The first engaging portion and the second engaging portion cooperates to form a filter seating arrangement at a filter seat position when assembled together to secure a filter within the CPR training device. The air passageway is open to air outside of the CPR training device only through the mouthpiece portion and the output portion. The filter is disposed in the air passageway at the filter seat position.

Devices and methods for delivering air to a patient are provided. A device includes a first portion having a first airflow inlet and a sensor configured to sense airflow, the first portion defining a first airflow path, and a second portion comprising a second airflow inlet, an impeller, and an outlet for communicating airflow to a patient, the second portion defining a second airflow path. The device includes means for coupling the first portion and the second portion, such that the sensor sensing airflow in the first portion causes corresponding movement of the impeller, wherein the impeller is configured to impel air through the second airflow inlet and out of the outlet to the patient, upon movement of the impeller.

Among other things, we describe a system that includes a first medical device for treating a patient at an emergency care scene, the first medical device including a processor and a memory configured to detect a request for a connection between the first medical device and a second medical device for treating the patient at the emergency care scene, the request for connection including an identifier of the second medical device, responsive to receiving the request for connection, enabling a wireless communication channel to be established between the first medical device and the second medical device based on the identifier of the second medical device and an identifier of the first medical device; and enabling transmission and/or exchange of patient data between the first medical device and the second medical device via the wireless communication channel. Such communications with more than two devices may also be possible.

A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about 7 cm H.sub.2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.
