They can be directly measured from the ventilator waveforms using occlusion maneuvers. Time constant is the product of compliance and resistance and represents the dynamic respiratory mechanics which is very useful at the bedside. In volume control mode, flow curve displays the ventilator settings, ...
This application note provides an overview of ventilator systems with a focus on system design for precision measurement and reliable protection. It discusses the four key components of a pneumatic ventilation system: gas supply, gas flow mixture, inhalation and exhalation systems. Within each of the...
Ventilator waveforms interpretation helps to understand the patient respiratory mechanics and optimize the ventilator settings. Ventilator waveforms combine curves and loops. Pressure and flow curves should be interpreted together using different time scale. They represent the interaction between the ventilator ...

Removal of carbon dioxide is affected by changing the minute ventilation, the product of the tidal volume and respiratory rate over a minute. In prescribing ventilator settings, it is important to match the respiratory rate and tidal volume to the underlying physiology...
In more severe cases, people with COVID may require hospitalization for advanced care. This may involve breathing supplemental oxygen or, if patients can’t breathe on their own, the use of a ventilator machine. There are three approved antiviral medications for COVID: nirmatrelvir/ritonavir (Pa...

Understanding pulmonary mechanics, elastic and resistive forces (compliance and resistance), and its influence on the inspiratory and expiratory time constant, and the mechanisms of gas exchange are necessary to choose the best mode of ventilation and adequate ventilator settings to minimize lung injury...
The cardiopulmonary interactions are reviewed in great detail, such as the alveolar air equation. A comprehensive review of mechanical ventilation as well as common initial ventilator settings are reviewed.doi:10.1007/978-3-319-31605-5_2Joseph Varon MD, FACP, FCCP, FCCM, FRSM...
