Valvular heart lesions have deleterious effects on hemodynamics in parturients during pregnancy. Cesarean section with an opioid-based general anesthesia is used to alleviate the adverse effects. We described a case of a 28-year-old primigravida at 37 weeks’ gestation with a diagnosis of severe mitral regurgitation, tricuspid regurgitation, and pulmonary hypertension in active labor. Cesarean s...

BACKGROUND A table of the approximate ranges of inspired oxygen delivered at given oxygen flow rates is often given on the packaging of oxygen masks. A study was carried out to check the inspired oxygen concentration given by one of the new masks, which has been designed to be used with or without the Venturi attachment as a result of the proposal to use it without the Venturi attachment as a g...

OBJECTIVE Exposure to organophosphates (OP) may lead to a life threatening cholinergic crisis with death attributed to a rapidly progressive respiratory failure. In a toxicological mass casualty event involving organophosphate exposure, many of the victims may depend on immediate short-term ventilation to overcome the respiratory distress which may exhaust life supporting resources. In addition...

Lung function measurement is difficult in unsedated infants; tidal breathing parameters are a useful non-invasive surrogate, but even these measurements cause disturbance from applying a facemask. We investigated a novel volumetric vest system (FloRight), which measures volume changes of the respiratory system from changes in the magnetic fields induced by current-carrying coils around the enti...

The COVID-19 pandemic has sparked passionate debate worldwide on matters of public health. A portion this been dedicated to the efficacy masks prevent spread COVID-19. While majority health officials agree that wearing a mask is efficacious, there widespread movement against masks. “anti-mask” often characterized for spreading misinformation about and its overlap with anti-vaccine movement. Thi...

Background Liberal oxygen therapy might increase the mortality rate of patients. Non-rebreathing masks (NRM) are a high-flow, non-invasive device that can provide concentration up to 95%. This study aimed determine impact using NRM in patients with respiratory failure. Methods retrospective cohort was conducted four medical institutions Taiwan from January 2010 December 2016. The association be...
