An inspiratory resistor valve system (IRV) to regulate intrathoracic pressure during positive pressure breathing, spontaneous inspirations, and CPR may include an inspiratory port. The IRV system may include patient port. The IRV system may include a separate expiratory port. The IRV may include a plurality of atmospheric pressure sensitive valves. The plurality of atmospheric pressure sensitive valves may isolate the expiratory port and the inspiratory port from one another.

Methods for using a manually actuated, self-inflating resuscitator device provides users with a positive pressure ventilation device that reliably provides a proper tidal volume to the patient and controls the rate of ventilation of the patient. The resuscitator device is lightweight, compact, durable, and quickly deployable in the field. The resuscitator device is preferably operable with one hand and can be configured for use in low-light environments.

A diagnostic tool can include a face mask, a casing, a plurality of sensors, and processing circuitry. The face mask can include an air-intake port, a first check valve integrated into the air-intake port, an air-exhaust port, and a second check valve integrated into the air-exhaust port. The casing can be coupled to the face mask having an air-intake chamber coupled to the air-intake port and an air-exhaust chamber coupled to the air-exhaust port. The processing circuitry can be communicatively coupled to the plurality of sensors. The processing circuitry can include computing logic for handling information detected by the plurality of sensors.

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.

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.

A resuscitation training device attaches to an air delivery ventilation device to determine if there is a proper mask seal between a live training subject or a training manikin. A pressure sensor attached to the resuscitation training device provides instant feedback to determine if there is a proper seal. The resuscitation training device includes a tubular member having an air metering orifice in fluid communication with the mask and the pressure sensor.

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.

A ventilator adaptor for switching between ventilator devices while maintaining respiratory support to a patient is described. The ventilator adaptor has a first movable element with a first inlet and a second inlet, and a second movable element movably attached to the first movable element and with an outlet. The outlet has an inner diameter of 14.5-15.5 mm, preferably 15 mm, and the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, preferably 15 mm. The outlet is in fluid communication with the first inlet in a first position or with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet with the first inlet or the second inlet. The outlet may be attached to an endotracheal tube in order to form a ventilation assembly.

A ventilation system for ventilation of a patient includes a patient interface device for attaching to the patient and a measuring and analysis device for measuring and analyzing breathing of the patient. The measuring and analysis device includes a connector housing defining a passage. A first portion of the connector housing is connected to the patient interface device. The measuring and analysis device further includes an air flow sensor and a pressure sensor disposed in the connector housing for measuring an air flow rate through the connector housing and a pressure in the connector housing respectively. The present device also includes a processor configured for data acquisition, data storage, data processing, and data output based on the air flow rate and the pressure, whereby the ventilation system is operable with real-time feedback based on the data output. A method for administering cardiopulmonary resuscitation is also provided.

There is provided a respirator for supplying clean air for a wearer. The respirator comprises a face assembly comprising an oronasal mask configured to seal against and cover a nose region and a mouth region of the wearer. The face assembly may be configured to be interchangeable on the respirator between a half-face assembly and a full-face assembly. The respirator comprises a securing headgear releasably securable with the face assembly, the securing headgear assembly configured to secure the respirator on a head of the wearer. The respirator comprises a facepiece assembly for supplying the wearer with air for inhaling and releasing air exhaled by the wear, the facepiece assembly releasably securable with the face assembly. One or more of the face assembly, the facepiece assembly, or the securing headgear are configured to be released from the respirator, sterilized, and releasably resecured with the respirator.
