Chronic IMR occurs as a late...
INTRODUCTION: Pneumothorax is abnormal collection of air in the pleural space occuring
when there is discontinuity between visceral and parietal pleura. When communication between bronchi,
alveololi and pleural cavity occurs, atsmopheric and intrapleural pressure are being equalized, which lead
to decrease in lung compliance thus causing collapsed...

Severe hypokalemia is a potentially life-threatening disorder and is associated with variable degrees of skeletal muscle weakness, even to the point of paralysis. On rare occasions, diaphragmatic paralysis from hypokalemia can lead to respiratory arrest. There may also be decreased motility of smooth muscle, manifesting with ileus or urinary retent...
An emergency department providing critical care will have an effect on outcome and intensive-care-units' resources by avoiding unnecessary or futile intensive-care admissions and thereby save hospital expenses. The study focussed on this result.
The study employed a retrospective analysis of prospectively collected data of out-of-hospital cardiac a...
Accurate and timely diagnosis of carbon monoxide (CO) poisoning is difficult because of nonspecific symptoms. Multiwave pulse oximetry might facilitate the screening for occult poisoning by noninvasive measurement of carboxyhemoglobin (COHb), but its reliability is still unknown. We assess bias and precision of COHb oximetry compared with the crite...
