It has been widely accepted that the most effective way to mitigate airborne disease transmission in an indoor space is to increase the ventilation airflow,measured in air change per hour(ACH).However,increasing ACH did not effectively prevent the spread of *** better understand the role of ACH and airflow large-scale patterns,a comprehensive fully transient computational fluid dynamics(CFD)simulation of two-phase flows based on a discrete phase model(DPM)was performed in a university classroom setting with people *** investigations encompass various particle sizes,ventilation layouts,and flow *** findings demonstrated that the particle size threshold at which particles are deemed airborne is highly influenced by the background flow strength and large-scale flow pattern,ranging from 5µm to 10µm in the cases *** effects of occupants are significant and must be precisely accounted for in respiratory particle transport *** enhanced ventilation design(UFAD-CDR)for university classrooms is introduced that places a premium on mitigating airborne disease *** to the baseline design at the same ACH,this design successfully reduced the maximum number density of respiratory particles by up to 85%.A novel airflow-related parameter,Horizontality,is introduced to quantify and connect the large-scale airflow pattern with indoor aerosol *** underscores that ACH alone cannot ensure or regulate air *** addition to the necessary ACH for air exchange,minimizing horizontal bulk motion is essential for reducing aerosol transmissibility within the room.

Phrenic nerve block: the key to managing acute biliary pain?

World Journal of Emergency Medicine 2024年第1期15卷 62-63页

Over the past two decades,the USA has witnessed a steep rise in the incidence of acute cholecystitis(AC),[1]even among children,[2]with over 200,000 cases annually.[3]Patients with AC often present to the emergency department(ED)experiencing severe distress,with most describing their pain level as“intolerable.”[4]Furthermore,there is usually a considerable delay before surgery,with a median time from diagnosis of AC to surgery of 28.5 h,[5]and a substantial percentage of patients wait as long as 10 d.[6]Prolonged delays before surgery lead to increased opioid use,which is associated with extended hospital stays and higher rates of readmission after cholecystectomy.[7]Furthermore,opioids can lead to vomiting,respiratory depression,delirium,and ultimately addiction.[8]We propose a novel regional anesthesia technique for managing AC:right phrenic nerve *** method could offer improved pain control and a more favorable risk profile in selected patients when compared to current ED practices.
