Detection of COVID-19 Using Heart Rate and Blood Pressure: Lessons Learned from Patients with ARDS [PDF]

arXiv, 2020
The world has been affected by COVID-19 coronavirus. At the time of this study, the number of infected people in the United States is the highest globally (7.9 million infections). Within the infected population, patients diagnosed with acute respiratory distress syndrome (ARDS) are in more life-threatening circumstances, resulting in severe ...

Brainstem involvement and respiratory failure in COVID-19

Neurological Sciences, 2020
Respiratory failure is the most worrisome problem of COVID-19. Patients may develop severe pneumonia requiring invasive mechanical ventilation and a significant proportion of them dies.

Mechanisms of Respiratory Failure

, 2006
A. In an adult, the limits of normality are a PaO 2 of >60 Torr (8 kPa). B. In the newborn, the oxygen tension needed to maintain the arterial saturation above 90% varies between 40 and 60 Torr (5.3–8 kPa) depending upon the proportion of hemoglobin that is fetal and the arterial pH (a drop in pH of 0.2 eliminates the left shift produced by 70% of the ...

Home Non Invasive Ventilation (NIV) treatment for COPD patients with a history of NIV-treated exacerbation:a randomized, controlled, multi-center study [PDF]

, 2016
BACKGROUND: In chronic obstructive pulmonary disease, the prognosis for patients who have survived an episode of acute hypercapnic respiratory failure due to an exacerbation is poor.

Endothelial biomarkers (Von willebrand factor, BDCA3, urokinase) as predictors of mortality in COVID-19 patients: cohort study

BMC Pulmonary Medicine
Background SARS-CoV-2 is a systemic disease that affects endothelial function and leads to coagulation disorders, increasing the risk of mortality.

Facilitating 1.5T MR‐Linac adoption: Workflow strategies and practical tips

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background MR‐guided radiotherapy (MRgRT) offers new opportunities but also introduces workflow complexities requiring dedicated optimization. Implementing magnetic resonance linear accelerator (MR‐Linac) technology comes with challenges such as prolonged treatment times and workflow integration issues.

Monitoring and Control System Development and Experimental Validation for a Novel Extrapulmonary Respiratory Support Setup [PDF]

arXiv, 2021
This paper presents a novel mechatronic setup intended for providing respiratory support to patients suffering from pulmonary failure. The setup relies upon the circulation of an oxygenated perfluorocarbon (PFC) through the abdominal cavity. Such circulation provides a potential pathway for the transport of oxygen to the bloodstream.

Non-Ventilator Management of Respiratory Failure: The Ventimask [PDF]

, 1973
This paper will detail the conservative management of acute respiratory failure in patients with chronic respiratory failure due to chronic bronchitis and emphysema. It is important to recognize that this is a very specific group of patients.

Outcome of lung cancer patients with acute respiratory failure requiring mechanical ventilation [PDF]

, 2004
To assess the weaning outcome of lung cancer patients with acute respiratory failure (ARF) requiring mechanical ventilation, we retrospectively analyzed the database of the respiratory intensive care unit at a university-affiliated tertiary care hospital.

Design and validation of a novel dosimetry phantom for motion management audits

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background We present a novel phantom design for conducting end‐to‐end dosimetry audits for respiratory motion management of two anatomical treatment sites. The design enables radiochromic film measurements of the dose administered to the target throughout the respiratory cycle (motion‐included) and the dose delivered to the time‐averaged ...
