Transthoracic ultrasonographic evaluation of diaphragmatic excursion in patients with chronic obstructive pulmonary disease

The Egyptian Journal of Bronchology, 2018
Background Chronic obstructive pulmonary disease (COPD) is a multisystem disorder that mainly besides the lungs also affects the muscle mass. The force generated by the respiratory muscles decreases, resulting in a negative effect on ventilation and ...

Retrospective Report of the Use and Outcome of High‐Velocity Nasal Insufflation in Cats (2019–2022): Eight Cases

Journal of Veterinary Emergency and Critical Care, EarlyView.
ABSTRACT Objective To describe the use and feasibility of high‐velocity nasal insufflation (HVNI) in cats. Design Retrospective descriptive study from 2019 to 2022. Setting University teaching hospital. Animals Eight cats that failed traditional oxygen therapy and, based on clinical evaluation, required more aggressive oxygen supplementation ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Sex differences in loop gain measured via superimposed end‐expiratory breath holds and inspired steady‐state hypoxia

Experimental Physiology, EarlyView.
Abstract Acute low oxygen exposure (hypoxia) elicits a hypoxic ventilatory response (HVR), which increases ventilation and mitigates hypoxaemia. During sustained exposure to hypoxia, ventilatory acclimatization increases peripheral chemoreflex (HVR) sensitivity or chemoreflex loop gain (LG).

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Maximal strength and voluntary activation of adductor pollicis after a single session of acute intermittent hypercapnia or acute intermittent hypoxia

Experimental Physiology, EarlyView.
Abstract Acute intermittent hypoxia (AIH) can increase maximal strength of limb muscles in people with incomplete spinal cord injury (SCI), but it is mostly untested in people without SCI. Acute intermittent hypercapnia (AIC) may engage similar respiratory circuits to AIH, but the effects of AIC on human limb motor output are unknown.

Comparative Evaluation of Incentive Spirometer and Diaphragmatic Breathing Exercise on Pulmonary Function and Functional Capacity in Drivers Exposed to Air-Conditioned and Non-Air-Conditioned Environments

International Journal of Physiotherapy
Background: Incentive spirometer (IS) and diaphragmatic breathing exercise (DBE) are simple, non-invasive interventions known to improve lung expansion, enhance ventilation, and strengthen respiratory muscles.

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

The Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...
