Performance of a new single-use bronchoscope versus a marketed single-use comparator: a bench study

BMC Pulmonary Medicine

Table 2 Primary endpoint: “mucus” mass suctioned in 30 s in Task 2 (N = 15)

Comparison of aScope 4 size versus EXALT Model B size	Mean mass of “mucus” suctioned in 30 s (g)		P value
Comparison of aScope 4 size versus EXALT Model B size	aScope 4	EXALT Model B	P value
Large versus Regular^a	41.5 ± 5.7	41.8 ± 8.3	0.914
Slim versus Slim	1.5 ± 0.6^b	4.3 ± 1.3	< .001
Regular versus Regular	15.4 ± 2.9	41.8 ± 8.3	< .001
Large versus Large	41.5 ± 5.7	72.9 ± 9.0	< .001

^aBased on a preliminary experiment, the study hypothesis was that the EXALT Model B regular scope would suction significantly more “mucus” than the aScope 4 large scope (not confirmed)
^bThere were 14 observations for aScope 4 Slim because one physician was called away for patient care and could not complete this task
