It is a common misconception that the pressure-target setting cannot be exceeded during pressure-targeted ventilation.A cough by the patient can cause the pressure to rise above the set value.This is why it is vital that a safe upper pressure limit,or maximum safety pressure,be set at approximately 10 cm H₂O above the pressure-target setting during pressure ventilation.
