Outcome measures
Primary outcome
Continuity of diaphragm thickness in the mid-axillary line in craniotomy-caudal direction, expressed through the intra-class correlation coefficient and bland-altman plot.
Secondary outcome
-)Continuity of diaphragm thickness in the posterior axillary and mid-clavicular line in cranio-caudal direction, expressed through the intra-class correlation coefficient and bland-altman plot.
-)Average absolute diaphragm thickness in mm in each line of measurement (i.e. posterior- and mixaxillary line, midclavicular line)
Background summary
Diaphragm thickness is usually measured in the zone of apposition, generally between the 8th and 10th intercostal spaces on the midaxillary line. In clinical practice, external factors such as surgical dressings or mechanical ventilation can limit this view however, necessitating deviation in crania-caudal or ventro-dorsal directions. With this in mind, we set out to evaluate the continuity of diaphragm thickness in cranio-caudal direction on three ventro-dorsal lines.
Study objective
Diaphragm thickness is constant throughout the zone of apposition in craniotomy-caudal direction
Study design
Measurements will be performed using a Philips CX 50 machine. Measurements will be taken once the volunteer is instructed and has performed the various breathing patterns.
Intervention
Ultrasound measurements of the right and left hemi-diaphragm
Inclusion criteria
Healthy volunteers >18 years able to follow respiratory commands
Exclusion criteria
Diaphragm paralysis or paresis in past medical history
