Estimation of Work of Breathing from Respiratory Muscle Activity In Spontaneous Ventilation: A Pilot Study

Applied Sciences, 2019
Work of breathing (WOB) offers information that may be relevant to determine the patient’s status under spontaneous mechanical ventilation in Intensive Care Unit (ICU).

The Effects of Chest Wall Loading on Perceptions of Fatigue, Exercise Performance, Pulmonary Function, and Muscle Perfusion

Sports, 2020
Background: Load carriage (LC), which directly affects the chest wall and locomotor muscles, has been suggested to alter the ventilatory and circulatory responses to exercise, leading to increased respiratory muscle work and fatigue.

Measurement of Work of Breathing in Infancy [PDF]

Pediatric 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

Clinical use of Heliox in Asthma and COPD

Monaldi Archives for Chest Disease, 2016
Heliox is a low density gas mixture of helium and oxygen commonly used in deep diving (> 6 ATM). This mixture has been also used for clinical purposes, particularly in the critical care setting.

Respiratory muscle work influences locomotor convective and diffusive oxygen transport in human heart failure during exercise

Physiological Reports, 2020
Introduction It remains unclear if naturally occurring respiratory muscle (RM) work influences leg diffusive O2 transport during exercise in heart failure patients with reduced ejection fraction (HFrEF).

Imposed Work of Breathing for Flow Meters with In-Line versus Flow-Through Technique during Simulated Neonatal Breathing. [PDF]

PLoS ONE, 2015
The ability to determine airflow during nasal CPAP (NCPAP) treatment without adding dead space or resistance would be useful when investigating the physiologic effects of different NCPAP systems on breathing.

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

Journal 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 ...

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

Türk 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.
