Extracorporeal lung support can be achieved using extracorporeal membrane oxygenation (ECMO) and extracorporeal CO2 removal. The ECMO systems allow a total lung support, providing both blood oxygenation and CO2 removal. Unlike ECMO, extracorporeal CO2 removal refers to an extracorporeal circuit that provides a partial lung support and selectively extracts CO2 from blood. ⋯ This is possible thanks to the continuous development of technology together with the customization of sedative protocols. Awake extracorporeal support is a specific approach in which the patient is awake and potentially cooperative while receiving ECMO. The present analysis aims to synthesize the main results obtained by using extracorporeal circuits in patients with respiratory failure, particularly in those patients with hypercapnia.

A Comparative Analysis of Ideal Body Weight Methods for Pediatric Mechanical Ventilation.
A universal method for determining ideal body weight (IBW) for the application of appropriate tidal volumes in children on mechanical ventilation is elusive. We sought to compare 3 commonly used IBW methods for subjects between ages 2 and 20 y. ⋯ The majority of the subjects demonstrated a clinically important error between the actual body weight and the IBW. The percent error increased in subjects > 25 kg actual body weight. These data underline the importance of obtaining height measurements and calculated IBW in pediatric patients who are mechanically ventilated.
