AI Article Synopsis
- - The study investigates the relationship between voluntary respiratory control and EEG signals, focusing on how brain activity correlates with different intensities of voluntary breathing.
- - Data from 11 participants showed that during voluntary respiration, there is an increase in low-frequency EEG power in specific brain regions, along with a decrease in sample entropy, indicating a strong correlation between breathing and brain activity.
- - The findings suggest potential for developing methods to identify voluntary respiratory consciousness and to monitor respiratory intentions noninvasively using brain-computer interfaces (BCIs).
Article Abstract
The perception of voluntary respiratory consciousness is quite important in some situations, such as respiratory assistance and respiratory rehabilitation training, and the key signatures about voluntary respiration control may lie in the neural signals from brain manifested as electroencephalography (EEG). The present work aims to explore whether there exists correlation between voluntary respiration and scalp EEG. Evoke voluntary respiration of different intensities, while collecting EEG and respiration signal synchronously. Data from 11 participants were analyzed. Spectrum characteristics at low-frequency band were studied. Computation of EEG-respiration phase lock value (PLV) and EEG sample entropy were conducted as well. When breathing voluntarily, the 0-2 Hz band EEG power is significantly enhanced in frontal and right-parietal area. The distance between main peaks belonging to the two signals in 0-2 Hz spectrum graph tends to get smaller, while EEG-respiration PLV increases in frontal area. Besides, the sample entropy of EEG shows a trend of decreasing during voluntary respiration in both areas. There's a strong correlation between voluntary respiration and scalp EEG. Significance: The discoveries will provide guidelines for developing a voluntary respiratory consciousness identifying method and make it possible to monitor people's intention of respiration by noninvasive BCI.

In-silico simultaneous respiratory and circulatory measurement during voluntary breathing, exercise, and mental stress: A computational approach.

Voluntary breathing (VB), short-term exercise (STE), and mental stress (MS) can modulate breathing rate (BR), heart rate (HR), and blood pressure (BP), thereby affecting human physical and mental state. While existing experimental studies have explored the relationship between VB, STE, or MS and BR, HR, and BP changes, their findings remain fragmented due to individual differences and challenges in simultaneous, BR, HR, and BP measurements. We propose a computational approach for in-silico simultaneous measurements of the physiological values by comprehensive prediction of the respiratory and circulatory system responses to VB, STE, or MS.

Article Synopsis
- The study assessed the safety of the Lmeca.A1000 automatic suction device compared to manual suctioning in ICU patients suffering from acute lung injury and respiratory failure.
- A multicenter, randomized trial involving 117 critically ill adults showed no significant differences in mucosal injury or pneumonia rates between the two methods.
- The findings suggest that the automatic suction device is safe and could reduce the workload for healthcare professionals without compromising airway management effectiveness.

Exercise-induced bronchoconstriction (EIB), a reversible airflow obstruction triggered by exercise, should be considered in patients presenting with symptoms of dyspnea, cough, wheeze, and chest tightness during or after vigorous exercise. Over the past several years, various diagnostic modalities have been developed and evaluated for the diagnosis of EIB, giving the clinician multiple options for diagnostic testing. Here, the authors present a review of the various testing options that can be used in the diagnosis of EIB, with a discussion of testing protocols and considerations for choosing the appropriate diagnostic test.
