ROX Index Versus MROX Index to Predict Treatment Outcome for High Flow Nasal Cannula And/or Noninvasive Ventilation in Patients with Respiratory Failure

Respiratory Failure (RF) is a condition where there's insufficient oxygenation in the body tissue, whether acute, chronic or acute on chronic; occurring due to decreased oxygen or excessive carbon-dioxide in the blood . There are four types of respiratory failure; Hypoxemic respiratory failure (Type1), hypercapnic respiratory failure (Type2), ) . Causes of RF are varied and accounted for any abnormality related upper respiratory tract, lower respiratory tract, central and peripheral nervous system or muscles of respiration . However, in the last three decades, the most common causes of RF is acute myocardial infarction (AMI), acute respiratory distress syndrome (ARDS), RF related to corona virus (Covid-19) and acute exacerbation of chronic obstructive lung disease (COPD).
