Disclosed herein are embodiments describing nonrebreather facemasks for efficiently and comfortably delivering oxygen to patients. One embodiment describes a cup-shaped pliable facemask that is suited to cover and seal a patient's nose, mouth, and cheeks within the cup-shaped facemask. Certain other embodiments describe an inlet tube outwardly extending from the facemask at an angle in line with the pathway of a patient's nostrils to better provide oxygen directly into a patient's nose. Other embodiments envision varying facemask's stiffness for improved comfort and sealing against the patient's face. While other embodiments envision a reduction in dead space of a facemask when worn by a patient to improve oxygen efficiency used by the patient.

The invention concerns a Venturi device (1) for delivering oxygen or an air/oxygen mixture comprising a main body (10) with an inner compartment (11) and a Venturi nozzle (20); a rear member (30) with an oxygen inlet (31), air inlets (32) and a mixing chamber (33) for mixing oxygen and air. The rear member (30) is mobile with respect to the main body (10) between a closed position wherein the rear member (30) provides oxygen to the Venturi nozzle (20), and an open position wherein the rear member (30) provides an air/oxygen mixture to the Venturi nozzle (20). The rear member (30) is mobile at least in rotation with respect to the main body (10) for allowing a user to manually select a desired open or closed position, preferably according to a helicoidal motion. Installation (100) for providing oxygen or an air/oxygen mixture to a patient comprising a gas reservoir (101), a flexible hose (103), a respiratory interface (104), a connecting hollow body (102), and such a Venturi device (1).

Systems and methods are provided for portable and compact nitric oxide (NO) generation that can be embedded into other therapeutic devices or used alone. In some embodiments, an ambulatory NO generation system can be comprised of a controller and disposable cartridge. The cartridge can contain filters and scavengers for preparing the gas used for NO generation and for scrubbing output gases prior to patient inhalation. The system can utilize an oxygen concentrator to increase nitric oxide production and compliment oxygen generator activity as an independent device. The system can also include a high voltage electrode assembly that is easily assembled and installed. Various nitric oxide delivery methods are provided, including the use of a nasal cannula.

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.

Disclosed is a nasal ventilation mask having separate ports to monitor end-tidal CO.sub.2 expulsion integrated into the mask in order to monitor end-tidal CO.sub.2 expelled nasally or orally. Also disclosed is a CPR mask for nose-to-mouth and/or mouth-to-mouth resuscitation, having a body shaped to cover the nose and/or mouth of a victim, the mask including a CO.sub.2 absorber for eliminating at least in part rescuer's exhaled CO.sub.2 delivered to the victim.

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.

Abstract: A traumatic brain injury (“TBI”) guideline system employing a patient monitoring sensor (30) and a patient monitoring device (10). In operation, the patient monitoring sensor (30) generates data for monitoring a TBI parameter of a patient (e.g., systolic blood pressure, blood oxygen saturation or carbon dioxide expiration of the patient), and the patient monitoring device (10) generates a TBI indicator derived from a comparison of the TBI parameter data to parameter guideline data associated with a poten -tial TBI of the patient. The patient monitoring device (10) may include a patient data monitor module (17a) to monitor the TBI parameter data, and a TBI monitor module (17b) to generate the TBI indicator. The TBI indicator is informative of a TBI status of the patient (e.g., a hypotension status, a hypoxia status or a ventilation status of the patient), and/or a TBI treatment for the patient (e.g., a ventilation treatment for the patient).

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.

An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen-depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen-enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.
