Electrical impedance tomography to determine optimal positive end-expiratory pressure in severe chronic obstructive pulmonary disease

Table 1 Measurements of lung mechanics at different PEEP levels

	ZEEP	50 % iPEEP	80 % iPEEP	100 % iPEEP	150 % iPEEP
Set PEEP (cmH₂O)	0	5	8	10	15
PEEP tot measured (cmH₂O)	10	10	11	11	15
Plateau pressure (cmH₂O)	18	21	20	19	21
Expired tidal volume (ml)	505	515	515	500	372
Static compliance (ml/cmH₂O)	63	47	57	62.5	62
