deadspace_equipment_ml: Calculate equipment deadspace in ventilator breathing circuit

In jackwasey/physiology: Calculate physiologic characteristics of awake and anesthetized adults, children and infants

Calculate equipment deadspace in ventilator breathing circuit

Description

There are minor brand variations between these airway devices. For the purposes of rough physiologic calculations, this function gives values based on real, widely-used equipment.

Usage

deadspace_equipment_ml(
  humidifier = c("adult", "infant", "none"),
  elbow = TRUE,
  flexible = c("none", "compressed", "extended"),
  min = 0
)

Arguments

humidifier	Single value, if TRUE, the default, then we assume the adult humidifier. If humidifier is set to the character string "adult", the results is the same as for TRUE. Alternatively, "infant" refers to the lower volume, higher resistance device.
elbow	Single logical value, default is TRUE
flexible	Single logical value or character string. If FALSE, the default, no additional flexible tubing is added. If TRUE, the volume of typical extended flexible tubing is added. If "compressed" or "extended" are given, the volume of flexible tubing in the given state is used.
min	numeric, giving the minimum number of obligatory milliliters of deadspace. The default is zero to allow calculation of additional airway elements.
