Respiratory model-based methods require datasets containing enough dynamics to ensure model identifiability for development and validation. Rapid expiratory occlusion has been used identify elastance resistance within a single breath. Currently accepted practice rapid involves 100 ms of the pathway. This article presents low-cost modular shutter attachment enable identification passive respiratory mechanics. Shuttering faster than creates without added muscular response closure, by...
Current positive airway pressure devices cost NZ$800-$2500, posing a financial barrier for the estimated 1 billion individuals worldwide with sleep apnea and those researching respiratory diseases. Increasing diagnoses research interest in area necessitate low-cost, easily accessible alternative. Thus, mePAP, high-quality, multipurpose, low-cost (∼NZ$250) device, was designed prototyped specifically disease research, particularly apnea. The mePAP allows user customization provides...
Respiratory disease is a major contributor to healthcare costs, as well increasing morbidity and early mortality. The device presented used simulate the effects of Chronic Obstructive Pulmonary Disease (COPD) in healthy people. intended use provide data equivalent COPD measured from those who are ill for initial validation respiratory mechanics models. It would thus eliminate need test unhealthy and/or fragile subjects, or invasive costly equipment based methods. conjunction with an...
Abstract In the majority of fractured oil and gas wells, conventional perforating is typical approach choice to provide primary connectivity fractures wellbore, in horizontal wells very discrete nature this connection assumes a significantly higher importance. multi-fractured drives ability efficiently place fracture treatments during pumping efficiency with which can subsequently be produced. Consequently, selection most appropriate technique absolutely key many aspects successful...
Respiratory disease is a growing health care crisis, and as result, so the requirement for mechanical ventilation (MV). Mechanical settings are historically determined by clinical judgement. However, use of respiratory modelling has potential to better determine improve patient-specific settings. model validation requires invasive methods and/or testing on vulnerable unhealthy people. Simulating non-invasively in healthy people would reduce need these methods. This paper presents simulation...
Resting breathing data was collected from 80 smokers, vapers, asthmatics, and otherwise healthy people in the low-risk clinical unit at University of Canterbury. Subjects were asked to breathe normally through a full-face mask connected Fisher Paykel Healthcare SleepStyle SPSCAA CPAP device. PEEP (Positive End-Expiratory Pressure) support increased 4 12 cmH2O 0.5 increments. Data also during resting ZEEP (0 cmH2O) before after trial. The trial conducted under Canterbury Human Research Ethics...
(1) Background: Technically, a simple, inexpensive, and non-invasive method of ascertaining volume changes in thoracic abdominal cavities are required to expedite the development validation pulmonary mechanics models. Clinically, this measure enables real-time monitoring muscular recruitment patterns breathing effort. Thus, it has potential, for example, help differentiate between respiratory disease dysfunctional breathing, which otherwise can present with similar symptoms such as breath...
Respiratory data was collected from 20 subjects, with an even sex distribution, in the low-risk clinical unit at University of Canterbury. Ethical consent for this trial granted by Canterbury Human Research Ethics Committee (Ref: HREC 2023/30/LR-PS). were collected, each subject, over three tests consisting of: 1) increasing set PEEP a starting point ZEEP using CPAP machine; 2) test 1 repeated two simulated apnoea's (breath holds) PEEP; and 3) forced expiratory manoeuvres ZEEP. Data custom...
The breathing dataset presented is collected from 20 healthy individuals at the University of Canterbury using a device to simulate pressure and flow profiles obstructive pulmonary disease. Specifically, expiratory non-linear resistance, which generates characteristic pressure-flow loop lobe seen in Ethical consent for trial was granted by Human Research Ethics Committee (Ref: HREC 2022/26/LR).

Neonatal mechanical ventilation (MV) is complex and its efficiency limited due to leakage of air around the endotracheal tube (ETT). Adult ETT cuffs cannot be used in neonatal patients block reverse flow as they cause damage delicate throat tissues. A novel design testing method for a non-contact cuff was developed validated. The goal minimise surface area contact, while creating resistance airflow using turbulence reduce ventilator increase efficacy treatment patients. Several designs were...
