    Thus, by analyzing the VO2 and VCO2 we can notice how quickly the patient reaches the AT. This is very important, I think, because if the AT assessment is done within 10 min in CPET and the patient reaches the AT within 3 minutes, then the patient following a major surgery for 2 hours since anaesthesia induction until extubation, will have around 12 independent chances to be acidotic at any stage of the surgery without the rate of those chances over time to be known due to uncertainty. However, the metabolic demand would be constant intraoperatively and then postoperatively for long and therefore that patient will need advanced haemodynamic and AGB monitoring especially the first 24 hours postoperatively. However, these numbers have no sense unless they have been compared with the patient profile and past medical history. Last but not least, I think that pre-habilitation with improvement even 0.5 min increase in AT, might save the patient’s life and/or keep their postoperative wellbeing.
