Table 1 Subjective EMT assessment of efficacy and ease of handling for LT and BVM ventilation after pre-study training using a 10-point scale regarding efficacy (1 = very low, 10 = very high) and ease of handling (1 = impossible, 10 = very easy)

From: EMT-led laryngeal tube vs. face-mask ventilation during cardiopulmonary resuscitation - a multicenter prospective randomized trial
