SpletThe target PCO2 chosen will vary with clinical circumstances. In the trauma patient free of head injury, the target PCO2 will likely be around the normal value of 40 mmHg, whereas a lower value (eg, 30 mmHg) might be chosen to reduce intracranial pressure in … SpletMean PaCO2 was 36.5 mmHg (4.87 kPa) with PC and 36.1 mmHg (4.81 kPa) with PRVC (p = 0.38). There were less fluctuations in ICP (p = 0.02) and PaCO2 (p = 0.05) with PRVC ventilation. Conclusions: Mean ICP and PaCO2 were similar for PC and PRVC ventilation in TBI patients, but PRVC ventilation resulted in less fluctuation in both ICP and PaCO2.
