Duration of prone position sessions: a prospective cohort study

open access: yesAnnals of Intensive Care, 2020
Background Prone position (PP) is highly recommended in moderate-to-severe ARDS. However, the optimal duration of PP sessions remains unclear. We searched to evaluate the time required to obtain the maximum physiological effect, and to search for ...

Bronchiectasis associated with severe COPD: Clinical, functional, microbiological and tomographic features

open access: yesLung India, 2022
Background: Bronchiectasis is frequently identified in patients with COPD, especially in severe patients, but the relevance of this finding remains unclear.

Monitoring Expired CO2 Kinetics to Individualize Lung-Protective Ventilation in Patients With the Acute Respiratory Distress Syndrome

open access: yesFrontiers in Physiology, 2021
Mechanical ventilation (MV) is a lifesaving supportive intervention in the management of acute respiratory distress syndrome (ARDS), buying time while the primary precipitating cause is being corrected.

Monitoring Dead Space in Mechanically Ventilated Children: Volumetric Capnography Versus Time-Based Capnography [PDF]

open access: yesRespiratory Care, 2015
BACKGROUND: Volumetric capnography dead-space measurements (physiologic dead-space-to-tidal-volume ratio [V D /V T ] and alveolar V D /V

Volumetric but Not Time Capnography Detects Ventilation/Perfusion Mismatch in Injured Rabbit Lung

open access: yesFrontiers in Physiology, 2018
Whereas time capnography (Tcap) is routinely displayed during mechanical ventilation, the volumetric representation (Vcap) is seldom used. We compared the diagnostic value of indices derived from Tcap and Vcap following ventilation to perfusion ratio ...

Volumetric capnography and chronic obstructive pulmonary disease staging [PDF]

open access: yes, 2020
Spirometry is difficult for some COPD patient to perform. Volumetric capnography could be a second choice test to evaluate the severity of functional disturbances. The aim of this work is to test this hypothesis.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

open access: yesExperimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

MEASUREMENT OF LUNG DEAD SPACE VOLUME BY CAPNOVOLUMETRY

open access: yesПаёми Сино, 2020
The article provides information on the lung dead space – a part of the respiratory volume that does not participate in gas exchange. The anatomical and alveolar dead spaces jointly together form the physiological dead space.

Lung function and stress echocardiography in pulmonary arterial hypertension: a cross-sectional study

open access: yesSão Paulo Medical Journal, 2021
BACKGROUND: The mechanism of exercise limitation in idiopathic pulmonary arterial hypertension (IPAH) is not fully understood. The role of hemodynamic alterations is well recognized, but mechanical, ventilatory and gasometric factors may also contribute ...

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4223-4234, 1 September 2026.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...
