Vital signs are an important source of information for patients in healthcare modeling, for many reasons:

• They are easy to collect.
• They are typically available at the beginning of the clinical encounter.
• They are objective.
• They are numerical indicators of patient health.

The vital signs included in this dataset are temperature, pulse, respiratory rate, blood pressure (systolic and diastolic), oxygen saturation percentage, and whether they are on oxygen. Height and weight are commonly also categorized as vital signs, but they are not included in our data. Let's take a look at each vital sign in turn.
