Description

Calculates the cvri, and further described in following publication ... [clinmon: An R package for calculation of clinical monitoring indices (2019)] Cvr formel - https://europepmc.org/article/pmc/pmc6054990 CVR = mean BP/mean MCAv

Usage

CVRi(df, del_1, del_2, trigger, blocksize, freq, blockmin, output)

Arguments

df

Data imported with 2 columns: time (in seconds), physiological measurement (raw measurement).

del_1

Deleter periods for pressure with two columns, first column is start of deletion period and last column is end of deletion period, every row is a deletion period. (dataframe)

del_2

Deleter periods for pressure with two columns, first column is start of deletion period and last column is end of deletion period, every row is a deletion period. (dataframe)

trigger

Trigger periods with two columns, first column is start of analysed period and last column is end of analysed period, every row is a period for analysis. (dataframe)

blocksize

Size of blocks created in seconds, default is 3 s. (numeric)

freq

Frequency of recorded data, default is 1000 Hz. (numeric)

blockmin

Minimum measurements ratio in every block, default is 0.5 (numeric)

output

select the resolution of output, either 'period' or 'block' (boolian)

Value

Returns a dataframe with the results, with either every period or block as a rows, depending on the chosen output
