ABSTRACT
Objective To study the rhythmic changes of 24 h ambulatory blood pressure in pre-eclampsia(PE)patients and come up with coping strategies. Method The levels and circadian variations of blood pressures in 240 pre-eclampsia patients were monitored and observed with 24 h ambulatory blood pressure monitoring. Results Among the 240 PE cases,121 were diagnosed as mild PE and 119 as severe PE.There were significant differences in the average of 24 h circadian variation,the average of date time variation,decreased blood pressure at night time between the two groups(all P<0.05). Conclusion Through ambulatory blood pressure monitoring,nurses can monitor the rhythmic changes of 24 h ambulatory blood pressure,make reasonable arrangements for the treatment and care operations,reduce the factors that induce eclampsia and ensure the safety of mother and baby .
ABSTRACT
Objective To resolve the problems of comprehensive evaluation on pilot's situation cognition basing on studying the mission situation. Methods The model of fuzzy comprehensive evaluation on pilots' situation cognitive was established on the basis of researches on concepts and methods of environmental quality evaluation in environment science.Results On the basis of theoretical consideration and analysis of experiments, the state of pilot's situation cognition was revealed preliminarily.Conclusion It is showed that the fuzzy comprehensive evaluation method on pilot's situation cognition can provide real and complete flight cognitive information. It is reliable basis for pilot's efficacy of training and flight safety.
