Table 6 Participant comments

Model I: BronchoBoy manikin

Bronchoscopic airway inspection: “The anatomy is good, but too easy to navigate”; “It can be used for basic training, but it cannot be used for evaluations”.

BAL: “Not room enough for fluids”.

Biopsy: “This is a plastic model… It is not good for biopsy as one cannot grab the tissue”.

When asked about the friction, color, and surface structure of the model: “The friction is ok, but it is a bit too stiff”. “It feels sticky, but similar to the Koken manikin”; “The mucosa does not look like human tissue”. “It is more pink, it looks artificial”.

Model II: Koken manikin

Bronchoscopic airway inspection: “It is possible to visualize the segments, but they cannot be entered”.

Biopsy: “It is not possible to acquire a sample in a plastic model”; “It is ok, but there should be something to grab”; “It is not as good as the porcine lung for simulation of tissue sampling”.

BAL: “It is acceptable with the balloons”.

When asked about the friction, color and surface structure of the model: “It feels sticky, it does not feel like in a patient”. “Not mucosal look”.

Model III: Human cadaver

Bronchoscopic airway inspection: “Seems darker”; “Easy to navigate this model”.

Biopsy: “There is no blood and no vessels. Sampling is easier without blood”.

When asked to advance the bronchoscope into the lung: “It looks like a bulla”.

Model IV: Preserved porcine lung

Bronchoscopic airway inspection: “Less friction compared to plastic manikins, so it is useful for basic bronchoscopy”; “Different anatomy”; “Good for training despite the different anatomy”.

When asked about the friction, color and surface structure of the model: “The human lung is more red, and you can see the vessels”.
