The normal value of P0.1 is 2 to 4 cmH2O.P0.1 respiratory central drive is a measure of the intensity of neural excitation required for the diaphragm to undergo contraction.
P0.1 has become a common method of assessing central function and an important reference index to help determine deconditioning, and its normal value is usually 2 to 4 cmH2O.The measurement of P0.1 is not interfered with by mechanical factors, such as airway resistance, and reflects respiratory central excitability and respiratory drive.
P0.1 greater than 6 cmH2O can not be off the machine, may be because of the respiratory muscle mechanical load is too heavy, the respiratory center compensatory activity is enhanced or the respiratory muscle function has not been fully restored, to produce a certain contraction force needs to be larger central drive. P0.1 too low suggests that the respiratory drive is reduced.
During the process of mechanical ventilation, the physiological functions of the patient should be strictly detected, including vital signs and the functions of important organs, especially the monitoring of respiratory function.
When discomfort occurs, please consult the hospital in time to avoid delaying the condition.
