Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

A ventilator, for the automated ventilation of a patient, includes a breathing gas delivery unit, at least one volume flow sensor for detecting a volume flow of the breathing gas, at least one breathing gas sensor for detecting a carbon dioxide concentration in the breathing gas, at least one pressure sensor for detecting a pressure of the breathing gas, as well as at least one computer. The computer is configured to actuate the breathing gas delivery unit as a function of the detected pressure and of a preset desired pressure value. The computer is further configured to perform an adaptation of the desired pressure value and an adaptation of a ventilation rate as a function of the detected volume flow and as a function of the detected carbon dioxide concentration.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.

Disclosed herein are systems and methods for producing an illumination pattern in a gas tube of a facially-fitting device, which is used in conjunction with a capnograph. The illumination pattern is determined by at least one illumination parameter, derived at least from measured CO.sub.2 data, such that the illumination pattern is indicative of at least one breath-related/physiological parameter and/or one or more of the respiratory/physiological conditions determined/assessed based at least on the CO.sub.2 data.

A fluid supply warning and communication system including a digital regulator in fluid tight engagement with a primary fluid reservoir. A method of using the fluid supply warning and communication system by flowing a fluid from a primary fluid reservoir to an end use appliance and detecting flow rate and pressure of the fluid with a digital regulator. A gas supply warning and communication system including an oxygen flow monitor that monitors SpO2, flow rate, pulse rate, and battery levels. A method of using the gas supply warning and communication system by flowing oxygen from a primary gas reservoir to an end use appliance, and measuring SpO2, flow rate, pulse rate, tank status, and battery levels.

A passive oxygen mask and vacuum regulation system disposed in fluid communication with a vacuum scavenging array includes a passive oxygen mask dimensioned to fit over a patient's nose and mouth and having a gas inlet port and an expired gas outlet port. A vacuum regulation assembly has a vacuum regulator which includes an expired gas discharge tube disposed in fluid communication between the passive oxygen mask and the vacuum regulation assembly, and a vacuum suction tube disposed in fluid communication between the vacuum regulation assembly and the vacuum scavenging array. The vacuum regulation assembly further comprising a vacuum attenuation port through a portion of a regulator housing, wherein the vacuum attenuation port is at least partially defined by an attenuation port diameter dimensioned to reduce a vacuum suction pressure in the expired gas discharge tube to a predetermined vacuum suction pressure.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The flow outlet airline is configured to be connected to an invasive ventilator circuit or a noninvasive ventilator circuit. The breath detection airline includes airline inlet. The airline inlet is separated from the airline outlet of the flow outlet airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

To provide a mask capable of reducing a load of a patient while suppressing lowering of accuracy at which a subject's exhaled air is measured. A mask to be put on a subject's face includes a mask body portion demarcating an internal space in a state of covering part of the subject's face and a cup-shaped nasal cup covering a subject's nose in a state of being arranged inside the internal space, in which the nasal cup includes a first wall portion covering the subject's nose, a second wall portion arranged under the subject's nostrils, and an exhaled air discharge portion guiding an exhaled air from the subject's nose to an exhaled air sensor, and at least part of the exhaled air from the subject's nose is guided toward the exhaled air discharge portion by the second guide portion in a state where the nasal cup covers the subject's nose.
