According to a preferred embodiment of the present invention there is provided a bite block assembly adapted for capnography and oxygen delivery to a subject, the bite block assembly (50) including a first capnography passageway adapted for passage therethrough of exhaled breath from the subject to a capnograph and a second oxygen delivery passageway, separate from the first passageway, adapted for passage therethrough of oxygen from an oxygen source to the mouth of the subject.

This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.

The invention provides an oral airway device that comprises three channels, which extend from the proximal to the distal end. The first channel is for supplying oxygen, the second is for the suctioning of fluids, and the third is for measuring carbon dioxide. The device allows for the patient's spontaneous respirations and provides other utility. The device is placed through the patient's mouth until the proximal end contacts the outside surface of the patient's lips, so that the distal end of the device reaches an area in the patient's throat above the trachea and the epiglottis. The device reduces the possibility for nasal mucosa inflammation, the risk of infection, and other medical complications. The device also allows the healthcare provider to insert it without first using a lubricant or spray. The device remains firmly in the correct position without the use of a strap.

A multi-functional oropharyngeal airway device designed to be inserted into the peripheral portion of a patient's oral airway to establish and maintain that airway. The components comprising the invention are a non-compressible, hollow cylinder body with at least three different and commonly used medical connectors incorporated into the proximal end of the body, and a flexible tube incorporated into the distal end of the body. The specific geometry and inclusion of the components of the airway device are arranged to be inserted and affixed into a peripheral position in a patient's mouth.

A respiratory support ventilator apparatus mechanically supports the work of respiration of a patient. The ventilator apparatus is highly portable and optionally wearable so as to promote mobility and physical activity of the patient, and to improve the overall health of the patient. The respiratory support ventilator may monitor a physical activity level and overall health status of the patient, and process this information. The information is used to track efficacy of the ventilation therapy relative to activity level and quality of life, and or to titrate or optimize the ventilation parameters to improve, maintain or optimize the physical activity level and overall health status of the patient.

An airway device for being inserted into an operative position in the upper respiratory tract extending from a patient's mouth to the patient's hypopharyngeal space is disclosed. The airway device forms a bore through which various medical and/or surgical implements may be inserted into the patient's airways. The airway device is contoured to approximately match the contour of the upper respiratory tract.

According to an embodiment of the present invention, a ventilation monitoring device comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured with the at least one processor to cause the ventilation monitoring device to determine whether an intubated subject's tracheal tube is properly placed by receiving an indication of a subject's breath from at least one sensor.

A device for measuring a concentration of a component in a target sample includes a flow chamber with a first channel that receives a reference sample having a known concentration of the component. The flow chamber also includes a second channel that receives the target sample having an unknown concentration of the component. A pump operates to pump the reference sample and the target sample at a same volume flow rate through the first and second channels, respectively. A thermal mass flow meter measures a thermal conductivity of the reference sample, a thermal conductivity of the target sample, or both.
