Does the Valsalva manoeuvre improve outcomes for SVT in the prehospital setting?
There is a lack of evidence supporting the efficacy of the Valsalva manoeuvre for SVT in the prehospital setting, necessitating future prehospital studies.
This review has shown that a standard of performance of the VM technique is defined within the medical literature, but no evidence exists to determine its efficacy or use in the prehospital setting. A prehospital study is therefore required to affirm the VM as part of prehospital clinical practice guidelines for SVT.
Smith et al. (Mon,) studied this question.
