The air gap sign.
An elderly female aspirated a donut and subsequently had loss of consciousness and cardiopulmonary arrest. Family members performed chest compressions until emergency medical services arrived and resuscitated the patient with an adequate heart rate and blood pressure. On hospital admission, the patient was nonresponsive on a mechanical ventilator. Cardiac auscultation revealed distant heart ton...
متن کاملUnder-water unidirectional air penetration via a Janus mesh.
Under-water and unidirectional air penetration, viz. air "diode", was effectively achieved on the basis of a composite mesh with Janus wettability. In the aqueous solution, the air bubbles can only pass through the mesh from the hydrophilic side to the superhydrophobic side, whereas they will be blocked from the opposite direction.
متن کاملChemical Characterization of the Indoor Air Quality of a University Hospital: Penetration of Outdoor Air Pollutants
For healthcare centers, local outdoor sources of air pollution represent a potential threat to indoor air quality (IAQ). The aim of this study was to study the impact of local outdoor sources of air pollution on the IAQ of a university hospital. IAQ was characterized at thirteen indoor and two outdoor locations and source samples were collected from a helicopter and an emergency power supply. V...
