Methods of evaluating a patient for PEEP therapy

摘要

Methods of automatically evaluating a patient for positive and expiratory pressure (PEEP) therapy include providing respiratory assistance to the patient with a mechanical ventilator. The patient is provided PEEP therapy at a first PEEP. A first end expiratory lung volume (EELV) is measured from the patient. PEEP therapy is provided to the patient at a second PEEP. A second EELV is measured from the patient. A difference from the first EELV and the second EELV is calculated. A value indicative of the patient's response to PEEP therapy is calculated from the difference between the first EELV and the second EELV.
