Calculating the work of breathing during mechanical ventilation
Journal of Mechanical Ventilation, 2021 Left figure: Passive patient esophageal pressure (Pes) in cmH2O on x-axis versus tidal volume in ml on y-axis. Green dashed line represents the chest wall compliance Right figure: same patient actively breathing on pressure support ventilation. (Pes) in

Characterizing and Modeling Breathing Dynamics: Flow Rate, Rhythm, Period, and Frequency
Frontiers in Physiology, 2022 The characterization of breathing dynamics provides researchers and clinicians the ability to differentiate respiratory compensation, impairment, disease progression, ventilator assistance, and the onset of respiratory failure.

Delivery of high flow oxygen through nasal vs. tracheal cannulas: A bench study
Frontiers in Medicine, 2023 BackgroundThe use of high flow oxygen therapy (HFOT) has significantly escalated during the COVID-19 pandemic. HFOT can be delivered through both dedicated devices and ICU ventilators. HFOT can be administered to a patient via a nasal cannula (NC).

Components of aircraft life support systems interact with each other and the user
Frontiers in Physiology, 2022 The life support system in a tactical aircraft provides necessary supplemental oxygen to the aircrew. However, interactions among its various components may generate unexpected breathing loads.

Physical Properties of Helium and Application in Respiratory Care
Encyclopedia, 2023 Helium is a low-density, inert, monoatomic gas that is widely used in medical applications. In respiratory care, Helium is mainly used as an adjunct therapy for patients with severe upper airway obstruction and asthma.

Inspiratory threshold loading negatively impacts attentional performance
Frontiers in Psychology, 2022 RationaleThere are growing concerns over the occurrence of adverse physiologic events (PEs) occurring in pilots during operation of United States Air Force and Navy high-performance aircraft. We hypothesize that a heightened inspiratory work of breathing

An Improved Dynamic Model for the Respiratory Response to Exercise
Frontiers in Physiology, 2018 Respiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ventilation.
