Extubation is a crucial step in the weaning process of critically ill mechanically ventilated patients. Some patients may develop postextubation respiratory failure that may lead to the need for re-intubation, which is associated with increased morbidity and mortality. This review comprehensively explores postextubation respiratory support strategies, focusing on the efficacy of high-flow nasal cannula (HFNC) oxygen therapy and noninvasive ventilation (NIV) in reducing re-intubation rates among various patient populations. ⋯ NIV, alternatively, appears to provide substantial advantages in reducing the rates of re-intubation and respiratory failure, especially in patients with obesity and patients with hypercapnia. Therefore, the indiscriminate application of these support strategies without consideration of individual patient characteristics may not improve outcomes, highlighting the need for careful patient selection and tailored therapeutic strategies based on specific risk factors and clinical conditions. By aligning postextubation respiratory support strategies with patient-specific needs, we may improve the success rates of extubation, enhance overall recovery, and reduce the burden of reintubations in the intensive care setting.

The growing prevalence of heat stroke as a public health issue, exacerbated by climate change and increasing global temperatures, demands an immediate and strategic response to prevent weather-related morbidity and mortality. Heat stroke results from the body's inability to cope with excessive heat, leading to systemic inflammatory responses, cellular apoptosis, and potential multiorgan dysfunction or failure. However, little information explicitly outlines how to perform cold-water immersion in the emergency department (ED), including potential patient selection, how much water or ice to use, target temperatures, when to stop, and complications or challenges with the process. ⋯ Additionally, the article addresses challenges and lessons learned during the protocol's implementation, emphasizing the importance of multidisciplinary collaboration, staff education, and the adaptation of ED infrastructure to support this lifesaving treatment based on its use during the last 3 years. The successful resolution of the presented cases, along with the protocol's potential for widespread adoption, illustrates the critical role of cold-water immersion in enhancing ED responses to heat stroke, offering a blueprint for future research and the development of similar protocols across health care settings. This work contributes to the evolving landscape of emergency medicine and aligns with the global effort to combat the adverse health effects of climate change.

Feasibility of estimating tidal volume from electrocardiograph-derived respiration signal and respiration waveform.
Estimating tidal volume (VT) from electrocardiography (ECG) can be quite useful during deep sedation or spinal anesthesia since it eliminates the need for additional monitoring of ventilation. This study aims to validate and compare VT estimation methodologies based on ECG-derived respiration (EDR) using real-world clinical data. ⋯ Although EDR-based VT estimation is promising, current methodologies are limited by noisy ICU ECG signals, but controlled environment data showed significant short-term correlations with measured respiration waveforms. Future studies should develop reliable EDR extraction procedures and improve predictive models to broaden clinical applications.

Detailed reports are scarce on minimally-invasive tracheostomy (MIT) techniques for critically ill patients with challenging anatomy or complex coagulopathies. In such high-risk patients, conventional percutaneous dilatational tracheostomy (PDT) may lead to severe complications. ⋯ The use of our refined care bundle enabled swift minimally-invasive tracheostomy in high-risk patients without the occurrence of serious complications.
