Table 1.
Differences in the main demographic clinical and functional parameters between the two groups of patients. Values are expressed as mean ± standard deviation. SAPS: simplified acute physiology score, ABG: arterial blood gases, NIV: noninvasive ventilation, RICU: Respiratory Intensive Care Unit, LTOT: long term oxygen therapy, and HMV: home mechanical ventilation.
