To review and illustrate the most common medical devices seen in critically ill patients using portable chest radiography in the ICU. To recognize and evaluate the correct position and common complications associated with these medical devices.

Chest radiographs are the most common imaging investigations undertaken in intensive care units because of their importance in evaluating the cardiorespiratory system; and obtaining a daily chest radiograph is standard practice in critically ill patients. Besides, any change in the patient’s condition, an intervention, as well as immediate imaging for all patients who have undergone placement of different devices can lead to several more studies. Therefore, the development of intensive care units and the advances in the treatment of those patients, have greatly increased the...

VASCULAR SUPPORT DEVICES: Cardiac devices CCD (Cardiac conduction devices) Pacemaker: A pacemaker is a device that regulates the heart rate using electrical impulses delivered through electrodes to the myocardium. They improve cardiac function, reduce the severity of clinical symptoms, and reduce mortality and morbidity.[Fig 2][Fig 3] Epicardial electrodes. Single-chamber pacemaker. Dual-chamber pacemaker. Cardiac resynchronization therapy (biventricular pacemaker): CRT usually involves atrial synchronized ventricular pacing to optimize atrioventricular timing with biventricular pacing to promote ventricular synchrony and improve ejection fraction, left ventricular size, and mitral regurgitation....

Chest radiography is an essential tool to evaluate medical devices in critically ill patients, and the radiologist must be able to recognize its proper placement, to understand its purpose, and to identify complicationsassociated with its use.
