You realize that it's been just a little too quite tonight when the radio suddenly cackles to life: 'Teenage girl. In the current age of hospital overcrowding, intubated patients are spending an increasingly longer period of time in the ED at times, they are even weaned and extubated in the ED before a bed becomes available upstairs.
