An example of delayed cycling during pressure-support ventilation of a patient with COPD, on a Puritan Bennett 7200 ventilator, which has a flow-termination of 5 L/min during pressure-support ventilation at 12 cm H2O. An example of delayed cycling during pressure-support ventilation of a patient with COPD, on a Puritan Bennett 7200 ventilator, which has a flow-termination of 5 L/min during pressure-support ventilation at 12 cm H2O. The ventilator cycles at 18 L/min. The pressure increase above the set pressure-support level causes the ventilator to pressure-cycle in response to the patient's active exhalation.
