The system comprising airflow sensors configured to obtain data indicative of airflow in the patient's airway and physiological sensors configured to obtain information regarding airflow in the patient's lungs. The system further including a monitoring device communicatively coupled to the airflow sensors and the physiological sensors. The patient monitoring device comprising at least one processor coupled to memory and configured to: provide a user interface on a display and assist the rescuer in determining proper placement of an endotracheal tube, receive the data indicative of the airflow in the patient's airway, receive the physiological information regarding the airflow in the patient's lungs, and determine whether the tube is properly placed based on the received physiological information, and present an output of the determination of whether the ET tube was properly placed.

Provided is an article for protection configured with at least one perforable, modifiable access point positioned to allow airway management procedures. Also provided is a method for maintaining the sterile environment during airway management procedures by covering a subject in need thereof with the article for protection.

A respiratory device for providing respiratory support to a patient includes an expandable bag and a rigid valve housing portion. The expandable bag includes an air intake valve, an adjustable predetermined tidal volume and a hinge configured to maintain the expandable bag in a predetermined tidal volume in an uncompressed configuration. The rigid valve housing portion in fluid communication with the expandable bag, the valve housing portion includes a peak inspiratory pressure (PIP) mechanism, an adjustable dial configured to adjust both the tidal volume of the expandable bag and a value of the PIP mechanism, a two-way valve configured to allow air to move from the expandable bag in a first direction through a first portion and directs air in an opposing direction through a second portion to create positive end-expiratory pressure (PEEP), and a PEEP controller comprising a PEEP dial configured to select a predetermined PEEP value provided by the two-way valve. The valve housing portion is capable of connecting to a patient breathing interface.

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.

A device and method for adjusting a tidal breath delivered to a patient. The device includes a moving frame which is configured to move over a stationary frame that is nested within the moving frame itself. Disposed between the moving frame and the stationary frame is a compressible bellows which delivers a tidal breath to the patient each time the moving frame is passed over the stationary frame. The specific volume of the tidal breath that is delivered may adjusted according to the estimated weight of the patient, thereby preventing over inflation of the patient's lungs while undergoing treatment. To adjust the tidal breath volume, the user quickly changes the relative position of a slide adjuster which dictates the range of possible movement between the moving frame and the stationary frame, thereby limiting the volume of air/oxygen which may be drawn into the bellows.

Respiratory diseases affect a large part of world population, especially in developing world. In this invention, we present a breathing support system to provide life-saving support to such patients. The system automates and regulates the use of a bag valve mask (commonly known as an ambu bag). The system uses mechanical actuators, sensors and a smart feedback control mechanism to automate and regulate the operation of the ambu bag to implement core functions of mechanical ventilation for life-saving applications. The system can also be used to provide better breathing support to newborns (e.g. to prevent hypoxia). The system can be used to save hundreds of thousands of lives in the developing world, in emergencies and during transportation globally.

An assistance apparatus for carrying out a first emergency care procedure, such as chest compressions or pulmonary ventilation, is configured to cooperate with a second assistance apparatus for carrying out a second emergency care procedure. The assistance apparatus comprises a communication device designed to receive, from the second assistance apparatus, data relating to the second emergency care procedure. The data comprises at least one item of information, a parameter or an instruction. A signal-processing device is configured to process the at least one signal measured according to the received data relating to the second emergency care procedure. An assistance system, comprising a compression assistance apparatus and a ventilation assistance apparatus, and an assistance method associated with the assistance system are also disclosed.

A ventilation monitoring system for assisting in proper placement of an endotracheal tube in a subject includes: a capnography sensor configured to be placed in fluid communication with the endotracheal tube and to provide information representative of the subject's breath; and a processor in communication with the capnography sensor. The processor is configured to provide an indication of proper endotracheal tube placement when (1) a first indication of the subject's breath and a positive result of a first auscultation are identified within a first predetermined time period, and (2) a second indication of the subject's breath and a positive result of a second auscultation are identified within a second predetermined time period. The first auscultation includes auscultation of a subject's left lung, right lung, left axillary region, right axillary region, or abdomen. The second auscultation includes auscultation of another region of the subject different from the first auscultation.

A mechanical compressor system is provided for actuating a bag of a bag valve mask. Rotatable track supports are shaped so as to define respective non-circular closed-loop tracks. Each of one or more mechanical compressors includes two pins that protrude from two sides of the mechanical compressor and engage one of the closed-loop tracks. The mechanical compressors are slidingly coupled to one or more vertical sliders configured to limit the movement of the mechanical compressors to a vertical translational pattern. A bag-coupler is configured to couple the bag to the mechanical compressor system in contact with the mechanical compressors. A motor or a manual crank is arranged to rotate the rotatable track supports, such that the pins move along the closed-loop tracks, causing vertical motion of the mechanical compressors along the one or more vertical sliders, which controls a volume of the bag. Other embodiments are also described.

The specific volume of the tidal breath that is delivered may adjusted according to the estimated weight of the patient, thereby preventing over inflation of the patient's lungs while undergoing treatment. To adjust the tidal breath volume, the user quickly changes the relative position of a slide selector which dictates the range of possible movement for the bellows to be compressed, thereby limiting the volume of air/oxygen which may be delivered by the bellows.
