RN, DrPh,Associate Professor Chika Nishiyama

Critical care nursing means providing the utmost care to severely ill patients in critical periods regardless of location, whether the ER, ICU, surgery ward or elsewhere. Life-threatening crises, however, can happen not only in hospital setting but anywhere, at any time, and to anybody in daily life. Therefore a conception including prehospital care is essential to critical care nursing. We are engaged in researching the inclusion of prehospital care which can be brought back to the emergency setting so as to save as many lives as possible.

Research and Education

  1. Overview
    We conduct our research using epidemiological methods with the goal of contributing to the development of emergency medical care and resuscitation science. Our major research themes are CPR education and the prevention of sudden cardiac death. We provide evidence from our epidemiological studies to real emergency settings and validate it in the real world to strengthen its reliability. We also conduct lectures and training sessions based on our study results for healthcare professionals and paramedics, and teach CPR to ordinary citizens and healthcare providers.
  2. Guiding Principles of our Research
    1) To form research questions conforming to the real/clinical setting and resolve them
    2) To maintain close cooperation with the real/clinical setting
    3) To generate evidence that can be utilized in policy and guidelines
    4) To return the research results to the general public and medical personnel
