Estimate breathing rate

Estimates rate from complete inter-trough breath periods or from the dominant respiratory-band spectral peak.

Usage

breathingRate(
  x,
  channel = NULL,
  method = c("peaks", "spectral"),
  band = c(0.1, 0.6),
  min_period_sec = 1,
  sr = NULL,
  assay_name = NULL
)

Arguments

x, channel, band, min_period_sec, sr, assay_name

As in respiratoryOnsets().

method

"peaks" for breath intervals or "spectral" for the dominant respiratory frequency.

Value

A data frame with one row per selected channel and columns channel, method, rate_bpm, n_breaths, and sd_bpm.

Examples

sr <- 10
signal <- sin(2 * pi * 0.25 * (0:599) / sr)
breathingRate(signal, sr = sr)
#>   channel method rate_bpm n_breaths sd_bpm
#> 1       1  peaks       15        14      0
