The Evidence for Evolution02:55

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.
The Scientific Method01:32

The Scientific Method

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...
The Scientific Method02:40

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
The Scientific Method03:50

The Scientific Method

Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.
Psychology as a Science01:13

Psychology as a Science

Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.
The scientific method in psychology involves six critical steps: making observations, formulating hypotheses, conducting tests, analyzing...
Scientific Nature of Social Psychology01:30

Scientific Nature of Social Psychology

Social psychology is a scientific discipline dedicated to understanding how individuals think, feel, and behave in social contexts. Unlike common sense, which relies on anecdotal experiences and intuition, social psychology employs systematic research and empirical methods to ensure objectivity and reliability. This distinction is fundamental in distinguishing scientifically supported findings from mere speculation.Four fundamental scientific values guide a structured approach to research in...

Summary

Evidence-based medicine (EBM) integrates clinical expertise with research evidence and patient values. For respiratory care, EBM supports noninvasive ventilation and lung-protective strategies while questioning weaning parameters and certain other therapies.

Area of Science:

  • Respiratory Medicine
  • Evidence-Based Practice

Background:

  • Evidence-based medicine (EBM) is crucial for clinical decision-making.
  • A hierarchy of evidence guides the strength of clinical recommendations.
  • Systematic reviews and guidelines are key to efficient evidence retrieval.

Purpose of the Study:

  • To evaluate the evidence supporting various respiratory therapies.
  • To highlight therapies with strong, equivocal, or no supporting evidence.
  • To underscore the value of EBM principles in respiratory care.

Main Methods:

  • Literature review focusing on systematic research and clinical practice guidelines.
  • Assessment of evidence strength for specific respiratory interventions.
  • Categorization of therapies based on supporting evidence levels.

Main Results:

  • Strong evidence supports noninvasive ventilation, lung-protective ventilation, and ventilator discontinuation protocols.
  • Evidence does not support weaning parameters, albuterol for ARDS, or adult high-frequency oscillatory ventilation.
  • Airway clearance, aerosol device selection, and PEEP for ARDS have equivocal evidence.

Conclusions:

  • EBM provides a valuable framework for respiratory care practice.
  • Clinical decisions should be guided by the best available research evidence.
  • Not all EBM tenets are universally accepted, but its principles remain important.
