Basic diaphragm ultrasound training: Curriculum implementation and learning trajectory among diaphragm ultrasound naive trainees

Table 1 Patient characteristics (n = 65), n (%)/mean ± SD

Characteristics
Age (years)	57.5 ± 14.0
Gender	Male: 49 (75.4); female: 16 (24.6)
BMI (kg/m2)	26.2 ± 9.3
Primary diagnosis	Gastrointestinal bleed: 1 (1.5); IHD/cardiac failure: 6 (9.2); ischemic stroke: 23 (35.4); intracranial events other than ischemic stroke (CVT, ICH, abscess, status epilepticus): 12 (18.5); myasthenia gravis: 2 (3.1); metabolic abnormality (hypokalaemia, myxoedema coma): 2 (3.1); polytrauma: 1 (1.5); pneumonia: 17 (26.2); urosepsis: 1 (1.5)
Presence of neuromuscular condition	4 (6.2)1
Respiratory rate (median, range)	20 (13-39)
Ventilation modes	Nil ventilation 26 (40); non-invasive ventilation 5 (7.7); invasive ventilation 34 (52.3)

¹Neuromuscular condition was defined as patient having a concomitant neuromuscular disease (2 had myasthenia, 1 had both myasthenia and facioscapulohumeral muscular dystrophy, 1 had critical illness myopathy).

In total, we imaged 52 patients. Some patients had repeated imaging, and so we had 65 separate occasions in which the 13 trainees received training. The data presented in Table 1 refers to the 65 different data points upon which the trainees were assessed. BMI: Body mass index; IHD: Ischemic heart disease; CVT: Cerebral venous thrombosis; ICH: Intracranial haemorrhage.
