An adaptor for generating flow includes an adaptor housing body. The distal end of the body has an oxygen inlet that extends extending into an interior of a distal air intake portion. The oxygen inlet has a nozzle with at least two apertures for directing oxygen into an interior of a distal air intake portion. The distal air intake portion includes at least one air inlet port to allow air to be drawn into the interior of the distal air intake portion, and a flow-resisting media covering at least a portion of the at least one air inlet port.

Respiratory fluid flow control device and method of using same

A ventilation system having a mask, a blowing assembly, and a processor. The mask has a mask body and a pressure sensor operatively associated with the mask body and configured to measure pressure within the mask. The mask body defines an inlet opening and a plurality of leak openings. The blowing assembly is positioned in fluid communication with the inlet opening of the mask body and configured to direct air to the inlet opening of the mask body. The processor is positioned in operative communication with the blowing assembly and the pressure sensor of the mask. The processor is configured to selectively control the blowing assembly based upon at least the measured pressure within the mask.

Ventilation devices and systems and methods of using same

A system and method for reducing the risk of fire in an oxygen delivery system. The system may include an oxygen delivery device with a controller in communication with a flow control valve to control a flow of oxygen through a tubing from an oxygen source to a patient interface. The controller may be programmed to close the flow control valve for a predetermined time period at a predetermined time interval to cause a periodic oxygen pause, the periodic oxygen pause to remove oxygen that may serve as an oxidizer when a fire is present inside at least one of the patient interface and the tubing.

Electronic firebreak systems and methods for use with oxygen delivery device

A connector for connecting an oxygen delivery device to a patient interface. The connector includes a housing with a first lumen for delivering oxygen and a second lumen to allow pressure to be measured. A third optional lumen may allow for gas sampling. The housing surrounding the first and second lumen has a portion that includes encoding for determining the type of patient interface being used, as well as a depth indicator sensor.

Apparatus for connecting oxygen delivery control instrument to patient delivery device

A method and apparatus deliver a variable flow of oxygen to a patient. The apparatus may include a flow control valve, a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values and to determine when a patient is inhaling. When the processor determines the patient is inhaling, the processor calculates an optimal oxygen flow rate to deliver to a patient, which may depend on a pre-selected flow rate and an oxygen backlog, and the processor sends a signal to the flow control valve to deliver the optimal oxygen flow rate to the patient.

System and method for delivery of variable oxygen flow

A system for detecting manual ventilation and selectively delivering a high flow of oxygen. The system comprises a source of compressed oxygen coupled to a first lumen of a nasal cannula, with an oxygen flow control valve coupled to a processor to control the flow of oxygen to the nasal cannula. A second lumen of the nasal cannula is in connection with a pressure sensor and the pressure sensor in connection with the processor. The processor may receive the pressure values and be programmed to determine when manual ventilation has occurred, and send a signal to the oxygen flow control valve to send a high flow of oxygen in response to manual ventilation.

Apparatus and method for oxygen delivery to a patient during manual ventilation

A system and method for prompting a patient experiencing ventilatory depression to breathe includes at least one sensor for detecting ventilatory depression by detecting inadequate breathing or lack of breathing in the patient. The system also includes one or more sensors for determining the type of breathing problem experienced by the patient. A sensor for detecting motion of the patient is used to determine whether the patient is moving. If inadequate or a lack of breathing is detected and the patient is not moving, the system provides verbal prompts or tactile stimuli to prompt the patient to breathe to improve patient ventilation.

System and method for detecting ventilatory depression and for prompting a patient to breathe

A positive pressure ventilation (PPV) appliance module includes an adapter that couples to a port on an NIV mask and an appliance for performing a respiratory care procedure. The adapter is configured to form a PPV seal with the port of the PPV mask and also form a PPV seal with the appliance. The PPV appliance module allows clinicians to perform procedures through the NIV mask without disrupting the therapeutic pressure.

Positive pressure ventilation appliance modules and related systems and methods

A system is configured to determine one or more breathing parameters of a subject, such as one or both of end-tidal carbon dioxide concentration and/or breath rate. The system is configured to make a plurality of preliminary determinations of an individual breathing parameter according to a plurality of different algorithms. A final determination of the breathing parameter is obtained by selecting one of the preliminary determinations based on therapy parameters, gas parameters, and/or other parameters that impact the accuracy and/or precision of the different algorithms.

System and method for determining one or more breathing parameters of a subject

A method and apparatus to identify the source of oxygen delivery failure to a patient. The apparatus includes a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values. When the oxygen flow rate value is greater than a predetermined threshold value, the processor is programmed to compare the breathing pressure values to the ambient pressure value and output an apnea alarm or an oxygen delivery device displacement alarm.

System and method for detection of oxygen delivery failure

A gas concentration monitoring system () may include a processor () configured to detect a concentration of a selected gas in a sample gas flow obtained from a physical interface () to a patient (); form a dataset including a plurality of data points, each data point corresponding to the detected concentration of the selected gas within the sample gas flow during a sampling time; group the data points according to a frequency of occurrence of the data points within the sampling time; and/or determine at least one of a signal confidence and signal quality based on relative characteristics between the groups of data points.

System for performing histogram analysis of the time-based capnography signals and method of operation thereof

A capnography system (), comprising: a controller () configured to obtain a sample gas flow from a physical interface () for a patient (); determine a change in a characteristic of the sample gas flow during a sampling time interval; determine whether the change in the characteristic of the sample gas flow during the sampling time interval is equal to or greater than a corresponding threshold value; determine that supplemental oxygen is provided when it is determined that the change in the characteristic of the sample gas flow is equal to or greater than the threshold value; and determine that supplemental oxygen is not provided when it is determined that the change in the characteristic of the sample gas flow is less than the threshold value.

Capnometry system with supplemental oxygen detection and method of operation thereof

A system is configured to perform capnometry/capnography, and/or other compositional analysis on a non-invasively ventilated subject. As such, the system determines amounts of a molecular species of gas (e.g., carbon dioxide, oxygen, etc.) excreted by the subject on a per-breath basis. Determinations of amounts of the molecular species of gas excreted are adjusted to reflect amounts of the molecular species of gas leaked from the non-invasive interface used to communicate with the airway of the subject.
