Correlation of Respiratory Physiologic Parameters in Mechanically Ventilated Coronavirus Disease 2019 Patients

Critical Care Explorations, 2021
Acute respiratory distress syndrome secondary to severe acute respiratory syndrome coronavirus-2 pneumonia or coronavirus disease 2019-related acute respiratory distress syndrome is the primary cause of mortality in coronavirus disease 2019. Some studies

Components of dead space and volumetric capnography.

, 2021
The expired tidal volume on the Y axis is plotted against the partial pressure of expired CO2 on the X axis in order to express the curve of ‘Volume = VCO2/FCO2’. Phase I represents CO2-free and pure dead space, phase II represents the transition between

Recombinant tissue plasminogen activator treatment for COVID-19 associated ARDS and acute cor pulmonale

International Journal of Infectious Diseases, 2021
Existing literature highlights the fact that patients with COVID-19 exhibit alterations in the coagulation process and are associated with respiratory and cardiovascular diseases, including acute respiratory distress syndrome and acute cor pulmonale.

The prognostic value of rapid shallow breathing index and physiologic dead space for weaning success in intensive care unit patients under mechanical ventilation

Journal of Research in Medical Sciences, 2019
Background: Mechanical ventilation (MV) is a life-saving intervention that should be considered for patients with respiratory failure. This study was conducted to evaluate the predictive value of physiologic dead space for weaning success and compare it ...

The effect of acute ventilation-perfusion mismatch on respiratory heat exchange in a porcine model.

PLoS ONE, 2021
BackgroundRespiratory heat exchange is an important physiological process occurring in the upper and lower respiratory tract and is usually completed when inspired gases reach the alveoli.

Is COVID-19 different from other causes of acute respiratory distress syndrome?

Journal of Intensive Medicine, 2023
Coronavirus disease 2019 (COVID-19) pneumonia can lead to acute hypoxemic respiratory failure. When mechanical ventilation is needed, almost all patients with COVID-19 pneumonia meet the criteria for acute respiratory distress syndrome (ARDS).

The effect of weightlifting training with added respiratory dead space on buffering capacity and blood lactate in weightlifters [PDF]

فیزیولوژی ورزش و فعالیت بدنی
Background and Purpose: Improvements in performance based on buffering capacity has been of great interest, where beneficial effects have been reported by using added respiratory dead space (ADRS) in endurance training.

Reductions in dead space ventilation with nasal high flow depend on physiological dead space volume: metabolic hood measurements during sleep in patients with COPD and controls

, 2018
Nasal high flow (NHF) reduces minute ventilation and ventilatory loads during sleep but the mechanisms are not clear. We hypothesised NHF reduces ventilation in proportion to physiological but not anatomical dead space.11 subjects (five controls and six ...

Contribution of Respiratory Muscle Oxygen Consumption to Breathing Limitation and Cyspnea

Canadian Respiratory Journal, 1997
During exercise, the sustainable activity of large muscle groups is limited by oxygen delivery. The purpose of this study was to see whether the oxygen consumption of the respiratory muscles reaches a similar critical value under maximal resistive ...

Estimation of dead space fraction can be simplified in the acute respiratory distress syndrome [PDF]

, 2010
Acute lung injury and acute respiratory distress syndrome are characterized by a non-cardiogenic pulmonary edema responsible for a significant impairment of gas exchange.
