Objectives:
The purpose of this study was to test the reliability of the Resuscitation Predictor Scoring (RPS) Scale1 (Appendix A), a survival prediction nomogram designed to aid resuscitation termination decisions during a resuscitation attempt.
Method:
Bivariate comparisons of predictors of survival and survival rates between the primary RPS Scale data set (1993-2000) and a secondary data set (2000-2003). A total of 2121 patients were included in the study.
Results:
Comparisons of the two sets of data showed an increase in resuscitation attempts for patients > or =80 years (p<0.001); an increase in pulseless electrical activity (PEA) (p=0.01) and an increase in the duration of arrests (p=0.012). However, in relation to the RPS Scale there were no statistical differences in survival between any of the sub groups demonstrating the reliability of the nomogram.
Conclusion:
The final updated RPS Scale demonstrates predicted survival rates 15 min into a resuscitation attempt. These can be poor and suggest that it is an acceptable point at which to first consider termination (where there has been no ROSC). The RPS Scale has demonstrated reliability and validity, but can only be a guide for the cessation of resuscitation.

01:20Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
