Measurement of Work of Breathing in Infancy [PDF]

open access: yesPediatric Research, 1981
Assessment of lung function in young children is extremely difficult unless sedation is given. If tidal exchange and intrathoracic pressure swings can be recorded, the severity of the respiratory problem can be measured by construction pressure-volume loops and calculating the work of breathing. The system we have used to measure tidal thoracic volumes

Comparison Between Dead Space/Tidal Volume and Work of Breathing in Predicting Extubation Failure in Critically Ill Children

open access: yesJournal of Pediatric Emergency and Intensive Care Medicine, 2018
Introduction: It was aimed to compare dead volume-to-tidal volume ratio (VD/VT) with work of breathing (WOBp) in predicting extubation failure in critically ill children undergoing mechanical ventilation treatment in pediatric intensive care unit ...

Assessment of respiratory flow cycle morphology in patients with chronic heart failure [PDF]

open access: yes, 2016
Breathing pattern as periodic breathing (PB) in chronic heart failure (CHF) is associated with poor prognosis and high mortality risk. This work investigates the significance of a number of time domain parameters for characterizing respiratory flow cycle

No effect of arm exercise on diaphragmatic fatigue or ventilatory constraint in Paralympic athletes with cervical spinal cord injury [PDF]

open access: yes, 2010
Cervical spinal cord injury (CSCI) results in a decrease in the capacity of the lungs and chest wall for pressure, volume, and airflow generation. We asked whether such impairments might increase the potential for exercise-induced diaphragmatic fatigue ...

Quantum Breathing Mode of Interacting Particles in a One-dimensional Harmonic Trap

open access: yes, 2012
Extending our previous work, we explore the breathing mode---the [uniform] radial expansion and contraction of a spatially confined system. We study the breathing mode across the transition from the ideal quantum to the classical regime and confirm that ...

Effect of resistive load on the inspiratory work and power of breathing during exertion. [PDF]

open access: yesPLoS ONE, 2012
The resistive work of breathing against an external load during inspiration (WR(I)) was measured at the mouth, during sub-maximal exercise in healthy participants.

Management of Mechanical Ventilation in Decompensated Heart Failure. [PDF]

open access: yes, 2016
Mechanical ventilation (MV) is a life-saving intervention for respiratory failure, including decompensated congestive heart failure. MV can reduce ventricular preload and afterload, decrease extra-vascular lung water, and decrease the work of breathing ...

Does Tube Resistance Compensation Change Metabolic Parameters When Added to Pressure Support Mode During Weaning?

open access: yesTürk Yoğun Bakim Derneği Dergisi
Objective: We postulated that adding tube resistance compensation (TRC) to pressure support ventilation (PSV) would have beneficial effects on metabolic parameters in patients scheduled for weaning.

Physiological effects of nasal high flow therapy during exercise in patients with chronic obstructive pulmonary disease: A crossover randomised controlled trial

open access: yesPulmonology
Background Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.Research question What is the effect of NHF during exercise ...
