Abstract: A rescue breathing apparatus and methods of operation for the rescue breathing apparatus are disclosed. The apparatus is an automatic rescue breathing unit (ARBU) device that includes a reservoir that is filled and/or drained according to alternative operations that may operate automatically or manually. One operation for filling and/or draining the reservoir is automatically controlled by a pneumatic logic circuit operating in combination with valves before and after the reservoir. A manual operation for filling the reservoir is controlled by a switch controlling flow into the reservoir.

Abstract: A rescue breathing apparatus and various components for use with the rescue breath apparatus are disclosed. The apparatus is an automatic rescue breathing unit (ARBU) device that includes at least two sub-systems—an airway device and a ventilation unit. In some instances, a compression pad is implemented with the ARBU device to prevent breaths during chest compressions. A breath pause button may be added to the ARBU device to pause breaths as controlled by personnel operating the ARBU device (e.g., a practitioner). A rescue breath kit with individual ARBU devices for different types of patients is also disclosed.

Abstract: A rescue breathing apparatus is disclosed. The apparatus is an automatic rescue breathing unit (ARBU) device that includes two sub-systems—an airway device keying mechanism and a ventilation unit. The keying mechanism may trigger and determine breath profile and parameters delivered by the ventilation unit. The ARBU device may connect to an air/oxygen source via a pressure regulator. The ARBU device may include a manifold, a keying chamber, an adult channel for providing breath to adult patients, a child channel for providing breath to child patients, and an infant channel for providing breath to infant patients. The ARBU device may also include a constant flow channel.

Abstract: Methods and apparatus for automated detection of an airway device coupled to an automatic rescue breathing unit (ARBU) are disclosed. The automatic detection apparatus includes a keying system that utilizes color adapters coupled to specific airway devices to indicate to a controller that the airway device is a particular size and has a particular airway protection classification (e.g., protected or unprotected). The controller may then determine the proper rescue breath rate and volume (e.g., tidal volume) based on knowing the size and classification of the airway device. In some instances, the controller may also receive information on chest compressions applied to the patient. Automatic detection of the size and classification of the airway device, along with chest compressions, may improve the process of providing automated rescue breaths to a patient.

Abstract: A ventilator system and method can deliver artificial respirations to a person receiving cardiopulmonary resuscitation. The system and method may provide intermittent breath delivery (e.g., with interruptions), so that activation of the device gives a specific predetermined number of breaths, interspersed with a set time period of no breath. This pattern may be by default, manually triggered where one activation gives a set number of breaths followed by a pause until the next activation for breath (one activation gives one breath cycle), or one activation results in continuous cycle of intermittent breaths). In some embodiments, a signaling mechanism may deliver signals to a rescuer relating to timing of chest compressions of the person. The timing of the chest compressions for the signals may be based on a time of delivery of the artificial respirations. In certain embodiments, different sized masks each include a gas flow restrictor which is unique for the size of mask.

Abstract: Provided is a method that includes automatically providing air/oxygen at a pre-selected maximum pressure limit, breath volume and respiratory-rate. The pre-selected maximum pressure limit, breath volume, and respiratory-rate are automatically set as a function of a size of a mask coupled to an air/oxygen supply system. Further provided is a ventilator system that includes a ventilator mask, a ventilator supply system, and a mask conduit. The ventilator mask is configured in a size that will fit upon a selected range of sizes of human faces. The ventilator supply system includes an air/oxygen source and an air/oxygen regulator system configured to regulate air/oxygen flow parameters as a function of the size of the mask. The mask conduit is configured to couple the ventilator supply to the ventilator mask.
