What is the target ETCO2 level during hyperventilation?

The target ETCO2 level during hyperventilation is aimed at maintaining a carbon dioxide level that is lower than the normal physiological range. The typical normal range for ETCO2 levels in a healthy adult is approximately 35-45 mmHg. During hyperventilation, the goal is to reduce the ETCO2 levels to help manage conditions such as severe respiratory distress or certain types of metabolic acidosis.

Setting the target at 30-35 mmHg allows the clinician to effectively decrease the CO2 levels to mitigate the effects of hypercapnia (excessive carbon dioxide in the bloodstream) while still ensuring that the patient does not become overly alkalotic, which can occur if the levels drop too low. This range thus represents an effective balance between reducing CO2 accumulation and avoiding adverse effects associated with excessively low levels of carbon dioxide, such as respiratory alkalosis.

The other options are either too low or too high compared to the established target during hyperventilation, highlighting the importance of maintaining a controlled and appropriate level of carbon dioxide in the management of trauma patients.
