FIELD: medicine. ^ SUBSTANCE: group of inventions refers to medicine, namely to resuscitation and intensive therapy, and can be used in executing cardiopulmonary resuscitation (CPR). That is ensured by chest compressions with using a device comprising a bar with an anteroposterior chest size scale, a force transfer contact element representing a strain-free support plate adjusted on a patient's chest, a sound-and-light indicator generating a sound and light signal of fixed frequency 100 times a minute a case of which comprises the bar to be mounted and fastened thereon, a contact element horizontal position sensor comprising a laser pointer, and a nomograph to determine an optimum excursion depth in length units. The nomograph has points 14 to 24 cm corresponding to the anteroposterior chest size, and dial graduations are provided in the form of steps formed by upper borders of nomograph columns which have height equal to 2.247xi cm where xi is a number of dial graduation specifying the anteroposterior chest size. The laser pointer is fixed on the support plate and directs a light ray in a field of the nomograph columns. Chest compression is executed in a projection of the middle one-third of breast bone by pressing through the strain-free flat surface of the contact element at frequency 100 in a minute at an excursion depth, with first 2-3 pressings made 50-70 % of the specified excursion depth. Compression is accompanied with sound and light signals radiated at pressing frequency, and the contact element is followed visually by projecting with a ray its position in a nomograph column field within upper and lower limits of the corresponding column. ^ EFFECT: invention allows providing the most effective CPR ensured by creating optimum artificial blood-groove volume in great vessels with simultaneous simplification of technical compression control facilities, and higher correct chest compression data reliability. ^ 2 cl, 12 tbl, 4 dwg |
