RESP refers to respiration, and RESP on the ventilator refers to the respiratory rate of a normal person. Normal human respiratory rate is the same as the physiological value, about 12-20 times / min, if the respiratory rate between 12-20 times / min is basically normal, lower than 12 times / min is called slow breathing, higher than 20 times / min is called hyperventilation. After these abnormalities appear to find the cause, these indicators suggest that there is a hidden disease behind the change in breathing range, so when the indicators are found to be abnormal should actively look for the cause.
