estimated PaO2=13.3 - (age/30) kPa or PaO2=100 - (age/4) mmHg
Cockroft-Gault formula to estimate creatinine clearance:
Creatinine Clearance (ml/min) = (140-age) x Weight (Kg) x Constant
Serum Creatinine (μmol/L)
Constant for males = 1.23, Constant for females = 1.04
Perioperative outcome described as mortality that is death within 30 days of the surgical procedure and/or morbidity which involves anesthetic or surgical complications that occur also within 30 days.

estimated MAC(age) = a x 10bx
x = Age – 40 years
b = − 0.00269
a = MAC at age 40 years ( halothane 0.75%, isoflurane1.17%, enflurane1.63%, sevoflurane1.8%, desflurane 6.6%)
Early mobilization, physiotherapy and occupational therapy facilitate post op recovery.
Slowly progressing loss of mental abilities which exceeds the normal age – related decline of brain efficiency
