Real time ultrasound is a useful way of assessing the diaphragm movement in real time. Real time ultrasound can be used to assess the amount of diaphragm contraction and mobility and also to visually demonstrate this to the patient. This can be extremely useful in situations where a patient’s problems may be realted to the way in which they are recruiting their diaphragm in certain activities. This can also be useful to detect abnormal diaphragm motion during respiration in patients who are critically ill.
