Calculate physiologic characteristics of awake and anesthetized adults, children and infants

A variety of formulae are provided for estimation of physiologic characteristics of infants, children, and adults. Calculations include: body surface area, ideal weight, airway dead-space, the alveolar gas equation, and GFR. Each formula is referenced to the original publication. Future functions will cover more material with a focus on anaesthesia, critical care and peri-operative medicine.

Future functions will cover more material with a focus on anaesthesia, critical care and peri-operative medicine.

Functions are provided for estimation of a range of physiologic characteristics of infant, child and adult humans.

  • Height, weight and fluid compartments.
  • Henderson-Hasslebalch
  • Alveolar gas equation
  • Airway dead-space

Each formula is referenced to the original publication. Warnings can be given for estimation based on input data outside of normal ranges. Future functions will cover more material with a focus on anaesthesia, critical care and peri-operative medicine.

Contributions welcome.
