  1. Related test-series with changes in one or maximal two parameters are grouped in one row. Numbers are values of the set parameters and do not reflect measured results. ID, internal diameter; Tinsp = inspiration time; I:E = inspiration to expiration time ratio; PEEP = positive end expiratory pressure; Pinsp, = set inspiratory airway pressure; VT = tidal volume; Paed, paediatric; std, standard; BIPAP = biphasic intermittent positive airway pressure; IPPV = intermittent positive pressure ventilation; ASB = assisted spontaneous breathing; CPAP, continuous positive airway pressure;
