get_metabolic_rate: Calculate Metabolic Rate

In Lightbridge-KS/rslab: Functions for Respiratory System Physiology Lab

Description

This function compute metabolic rate (Cal/m2/hr) from Harvard Spirometer tracing, subject's weight and height, and environmental condition i.e., barometric pressure and temperature. The output printed to console will show each step of calculation which is suitable for educational purposes.

Usage

get_metabolic_rate(
  x,
  y,
  paper_speed = 25,
  baro,
  temp_c,
  wt_kg,
  ht_cm,
  cal_eqi_oxygen = 4.825
)

Arguments

x	Displacement of tracing in x-direction (in millimeter).
y	Displacement of tracing in y-direction (in millimeter).
paper_speed	Paper speed of the kymograph (in millimeter/minute), 25 ml/min by default.
baro	(If condition = "STPD") Barometric pressure at the recording site.
temp_c	(If condition = "STPD") Temperature in celsius at the recording site.
wt_kg	(Numeric) Weight of the subject in kilogram
ht_cm	(Numeric) Height of the subject in centimetre
cal_eqi_oxygen	(Numeric) Caloric equivalent of Oxygen (default is 4.825, at RQ = 0.82)

Value

Report printed to console, return metabolic rate in Cal/m2/hr, invisibly

Examples

get_metabolic_rate(x = 20, y = 10,
                   baro = 760, temp_c = 25,
                   wt_kg = 80, ht_cm = 180)
