Impact of Adjusted Cardiopulmonary Resuscitation Process on Return of Vital Signs and Spontaneous Circulation in Cardiac Arrest Patients in Emergency Unit

Objective: To study how effectively an adjusted cardiopulmonary resuscitation process (CPR)
could restore vital signs and spontaneous circulation in cardiac arrest patients treated in an emergency
unit.
Design: Quasi-experimental with a two group design.
Methodology:Thesampleconsistedof60cardiacarrestpatientsreceivingCPRinanemergency
unit of Kamphaengphet Hospital. The participants were divided equally and assigned to an unadjusted
CPR group and an adjusted CPR group. Data were collected through the patients’ medical records
and the CPR speeds recorded by the emergency unit’s video. The patients’ baseline characteristics
were analysed using descriptive statistics. The CPR time differences were compared using an
independent T-test, whilst the patients’ rates of return of vital signs and of survival were compared
using an Exact Probability test.
Results: There was no signifcant difference in baseline characteristics between the two groups.
However, the CPR process conducted by the adjusted CPR group was signifcantly faster than that
by the unadjusted CPR group. In the adjusted CPR group, chest compression, defribillation, tracheal
intubation, and adrenalin injection were completed in a signifcantly shorter time (p < 0.05) than in
the unadjusted CPR group. In addition, the patients in the adjusted CPR group displayed signifcantly
higher rates of return of vital signs and of spontaneous circulation (hence survival) than their unadjusted
CPR counterparts did (p < 0.05).
Recommendations: Adjustment of the CPR process by defning the working area, building
good teamwork, and systematically managing the equipment and medications can enhance the
effectiveness of CPR. With a faster speed, the adjusted CPR process is likely to increase cardiac
arrest patients’ chance of regaining vital signs and survival. It is recommended, therefore, that the
concept of CPR process adjustment be applied to emergency unit management.
