[Ten-year evolution of mechanical ventilation in acute respiratory failure in the hematogical patient admitted to the intensive care unit].

Objective: A comparison was made between invasive mechanical ventilation (IMV) and noninvasive positive pressure ventilation (NPPV) in haematological patients with acute respiratory failure.

Design: A retrospective observational study was made from 2001 to December 2011.

Setting: A clinical-surgical intensive care unit (ICU) in a tertiary hospital.
