Monitoring Critically Ill Patients

Vital basics on vital signs and other signs that are vital.

Our goal in medicine is to gather and organize data, interpret that data and ultimately make decisions in the prevention, diagnosis, and management of disease.  The initial part of this system is to ensure that adequate and correct data is collected and interpreted with knowledge of the process and shortcomings that the data was collected with.

Discussion includes vital signs, pulse oximetry, blood gases, capnography/end-tidal C02 (ETC02) and more.  It is important to recognize where vital signs can trick you, how to deal with pulse oximetry latency and how blood gases and ETC02 can be interpreted in the setting of shock.

    Is there more information for that picture?

    • Brandon Parker says:

      yea, sorry I will discuss this concept in the podcast and in the notes. Essentially what it is showing is that ETC02 is a depiction of ventialation more than perfusion in pts with normal CO but with declining CO those parameters swap and after a drop of 40% the ETC02 is a measurment of CO.

    thanks! Learned a lot
