The MAP is the average blood pressure in a person's blood vessels during a single cardiac cycle. It is important to calculate the MAP during the management of patients with acute conditions where there is a concern for appropriate organ perfusion.
\( MAP = DBP + (SBP - DBP)/3 \)
Note: DBP = diastolic blood pressure; SBP = systolic blood pressure
E.g., if the SBP is 120mmHg, and the DBP is 80mmHg, then the MAP is:
80 + (120-80)/3
[1] 93.33333
With this shiny app, you can easily calculate the MAP based on two inputs:
No more wasting time doing manual calculations while you're managing your acute patients!
The calculated MAP will also be accompanied by a corresponding comment, depending on its value:
library(knitr)
library(kableExtra)
text_tbl <- data.frame(MAP = c("<60 mmHg", "60-100 mmHg", ">100 mmHg"), Comment = c("Too low","Normal","Too high"))
kable(text_tbl) %>%
kable_styling(full_width = F)
| MAP | Comment |
|---|---|
| <60 mmHg | Too low |
| 60-100 mmHg | Normal |
| >100 mmHg | Too high |

How to use the app:
Enter the systolic blood pressure and diastolic blood pressure readings into the side bar. Click 'Calculate' to obtain the resulting MAP.
