  1. Non-adjusted model adjust for: None
  2. Model I adjust for: mortality
  3. Model II adjust for: Gender, ASA classification, procedure length, Combined PASP and RVSP, mortality, Intrathoracic, systemic hypertension, Venous thromboembolism, Asthma, Renal failure (serum creatinine > 1.5 mg/dl), and Heart Rate
