Appropriateness of currently recommended chest compression depth based on mean depth from skin landmark to maximum left ventricular diameter in cardiopulmonary resuscitation in Thai people: a multicenter retrospective study

this study was performed to evaluate the appropriateness of the mean depth from a skin landmark to the maximum left ventricular diameter (LV max) with a 5- to 6-cm depth by comparing the HCF using mathematical methods with contrast-enhanced chest CT in Thai people.
