Monitoring the critically ill equine patient

Measurements of physiologic parameters, such as blood pressure or lactate concentration, are useful to detect occult derangements, such as tissue hypoxia and dysoxia. These tools are also useful in determining the effects of therapy. Monitoring techniques are now widely available for the intensive management of critically ill horses and foals. A number of these have evolved into noninvasive or minimally invasive devices and procedures and provide information that can be used for earlier and more dynamic therapeutic intervention. The goal of increased monitoring is to improve the level of care in the ICU; L ultimately. increased survival of critical patients is the motivation behind enhanced monitoring of physiology, with particular attention being paid to trends or alterations over time. This review highlights practical and informative monitoring tools and techniques and provides normal reference values from the literature.
