“…With the least amount of patient cooperation, the exhaled breath waveform recording can be performed. The data recording can therefore be repeated without being altered (Godoy et al, 2023;Tiller et al, 2021). Using a nasal cannula and monitoring equipment, the system is simple to set up and straightforward to be carried out.…”

The goal of the exhaled breath waveform used in ventilation monitoring is to improve COVID-19 illness detection. Using exhaled breath patterns to differentiate between COVID and non-COVID healthy individuals, an algorithm for valid exhaled breath waveform segmentation and feature computation is created to identify the COVID-19 infection. A two-minute exhaled breath pattern was recorded using a device and a nasal cannula sampling tube, resulting in the collection of exhaled breath waveforms from each subject. The developed algorithm is utilized to evaluate the valid exhaled breath waveforms and compute the features classified to distinguish between individuals who contracted COVID-19 infection and this who are healthy. Slope e2, activity e2 and intersection angle of expiration and inspiration phase showed p-value of 0.000, denoting the strong significance difference between COVID-19 patients and non-COVID healthy individuals. The statistical analyses revealed p-values of 0.039, 0.008, and 0.024 for area e2, mobility of e2 and complexity e3, indicating its significance in differentiating COVID-19 patients with non-COVID healthy individuals. The slope, area, and intersection angle as significant features showed good predictive power for compliance with p-value analysis with area under the receiver operating characteristic curve with 0.667, 0.693, and 0.775. Slope of e2, area of e2, intersection angle of expiration and inspiration phases are identified as the promising features to be chosen in discriminating COVID and non-COVID individuals.

“…Furthermore, promoting positive beliefs and attitudes among patients vis à vis treatment and debunking any misconceptions or fears they harbour could also serve to enhance adherence to treatment. Elsewhere, Godoy et al investigated the combination of awake prone positioning with HFNO in a systematic review of 13 studies totalling 1242 patients [79]. They concluded that there was an encouraging pathophysiological rationale for the use of this combination of techniques to improve oxygenation, but they suggest that consensus remains warranted regarding the criteria for timing, management and, above all, discontinuation before this approach could be generalized.…”

The emergence of the new SARS-CoV-2 in December 2019 caused a worldwide pandemic of the resultant disease, COVID-19. There was a massive surge in admissions to intensive care units (ICU), notably of patients with hypoxaemic acute respiratory failure. In these patients, optimal oxygen therapy was crucial. In this article, we discuss tracheal intubation to provide mechanical ventilation in patients with hypoxaemic acute respiratory failure due to SARS-CoV-2. We first describe the pathophysiology of respiratory anomalies leading to acute respiratory distress syndrome (ARDS) due to infection with SARS-CoV-2, and then briefly review management, focusing particularly on the ventilation strategy. Overall, the ventilatory management of ARDS due to SARS-CoV-2 infection is largely the same as that applied in ARDS from other causes, and lung-protective ventilation is recommended. The difference lies in the initial clinical presentation, with profound hypoxaemia often observed concomitantly with near-normal pulmonary compliance.

“…A high flow of heated and humidified air can be utilized either independently or in conjunction with oxygen in order to produce varying levels of inspiratory oxygen fractions (FiO 2 ) that span from 0.21 to 1 [2]. HFOT demonstrated serious advantages in improving gas exchange and enhancing patients' tolerance to oxygen therapy, sometimes reducing the rate of re-intubation [3].…”

High-flow oxygen therapy (HFOT) is a respiratory support system, through which high flows of humidified and heated gas are delivered to hypoxemic patients. Several mechanisms explain how HFOT improves arterial blood gases and enhances patients’ comfort. Some mechanisms are well understood, but others are still unclear and under investigation. HFOT is an interesting oxygen-delivery modality in perioperative medicine that has many clinical applications in the intensive care unit (ICU) and the operating room (OR). The purpose of this article was to review the literature for a comprehensive understanding of HFOT in the perioperative period, as well as its uses in procedural sedation. This review will focus on the HFOT definition, its physiological benefits, and their mechanisms, its clinical uses in anesthesia, and when it is contraindicated.
