The stages of anesthesia are:
- Stage 1 - Induction - It is the stage between the administration of the medicine and the loss of consciousness.
- Stage 2 - Excitement stage - After the loss of consciousness, the breathing becomes erratic, pupils dilate, and the patient’s breathing becomes irregular.
- Stage 3 - Surgical anesthesia - This is when the surgery begins. The muscles relax and the breathing is depressed.
- Stage 4 - Overdose - When too much drug is administered, the respiratory and cardiovascular system collapse.
