Lines and tubes (chest radiograph)

Lines and tubes are important components in chest radiographic evaluation.

Nasogastric (NG) tube

See: nasogastric tube positioning

Correct position
Endotracheal tube (ETT)

See: evaluation of endotracheal tube position.

Correct position
  • ETT tip 5 cm +/- 2 cm above carina
  • selective intubation (contralateral lung collapse/hyperinflation of ipsilateral lung/pneumothorax)
  • tooth aspiration
Central venous line/catheter (CVL/CVC)
Correct position
Intercostal tube/catheter (ICC)

See: intercostal catheter

Correct position
  • intercostal tube tip lies between visceral and parietal pleura
  • placement into lung parenchyma, interlobar fissure or subcutaneous tissue
  • mediastinal or abdominal visceral trauma
  • re-expansion pulmonary edema
Correct position
  • single chamber: electrode tip in right atrial appendage (atrial pacing) or right ventricular apex (ventricular pacing)
  • dual chamber: electrode tips in right atrium and right ventricular apex
  • biventricular: electrode tips in right atrium, right ventricle and coronary sinus
  • implantable converter defibrillator: electrode tip in apex of right ventricle
  • lead malposition (dysrhythmias)
  • pneumothorax
  • myocardial perforation
  • lead fracture
