Combined Unilateral Blockade of Cholinergic, Peptidergic, And Serotonergic Receptors in The Ventral Respiratory Column Does Not Affect Breathing in Awake Or Sleeping Goats [PDF]

, 2015
Previous work in intact awake and sleeping goats has found that unilateral blockade of excitatory inputs in the ventral respiratory column (VRC) elicits changes in the concentrations of multiple neurochemicals, including serotonin (5-HT), substance P ...

Optimization techniques in respiratory control system models [PDF]

, 2016
One of the most complex physiological systems whose modeling is still an open study is the respiratory control system where different models have been proposed based on the criterion of minimizing the work of breathing (WOB).

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.

PEMBERIAN HIGH FLOW NASAL CANNULA PADA PASIEN DENGAN ACUTE LUNG OEDEMA DENGAN MASALAH KEPERAWATAN POLA NAPAS TIDAK EFEKTIF [PDF]

, 2023
Background: Acute lung edema is an emergency condition that requires action as soon as possible because it will be fatal due to disruption of the gas exchange process in the alveoli, if not treated quickly it will have an impact on death.

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.

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.

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).
