Table 1 Situations in which NIV should be encouraged or avoided in hematology patients

From: Non-invasive mechanical ventilation in hematology patients: let's agree on several things first

Avoid NIV

   Acute respiratory failure-associated septic shock

   Nonhyperbaric deterioration of consciousness

   Deep hypoxemia with criteria for ARDS (PaO2/FiO2 <200)

   Multiple organ dysfunction

   Persistent tachypnea after the first hour under NIV (respiratory rate >35)

Encourage NIV

   NIV in patients with isolated respiratory failure and no sign of respiratory distress and no deep hypoxemia

   NIV in hematology patients with chronic respiratory failure

   NIV in hematology patients with pulmonary edema

   NIV in hematology patients to secure fiberoptic bronchoscopy

   NIV in hematology patients who declined tracheal intubation

  1. ARDS, acute respiratory distress syndrome; NIV, non-invasive mechanical ventilation; PaO2/FiO2, ratio of partial pressure of arterial oxygen to the fraction of inspired oxygen.
