Convert Lung Volume from ATPS to BTPS

Source: R/btps.R

This function converts several lung volume parameters at ATPS (Ambient Temperature and Pressure Saturated) to lung volume at BTPS (Body Temperature, Pressure, water vapor Saturated).

lung_vol_atps_btps(
  temp = NA,
  FEV1 = NA,
  FVC = NA,
  PEF = NA,
  TV = NA,
  IC = NA,
  EC = NA,
  VC = NA
)

Arguments

temp

(Numeric) Room Temperature in celsius when gas was collected.

FEV1

(numeric) Forced Expiratory Volume in 1 second (L).

FVC

(numeric) Forced Vital Capacity (L)

PEF

(numeric) Peak Expiratory Flow (L/min)

TV

(numeric) Tidal Volume (L)

IC

(numeric) Inspiratory Capacity (L)

EC

(numeric) Expiratory Capacity (L)

VC

(numeric) Vital Capacity (L)

Value

A Tibble

Examples

lung_vol_atps_btps(temp = 30, FEV1 = 5, FVC = 10, PEF = 4, TV = 9, IC = 10, EC = 12, VC = 10)
