Respiratory system TERMS TO KNOW Spirometer- measures respiratory volumes Spirogram- Inspiratory reserve volume (IRV )-amount of air that can be forcefully inhaled after a normal tidal volume inhalation (3100ml) Tidal volume (TV)- amount of air inhaled or exhaled with each breath under resting conditions (500ml) Expiratory reserve volume (ERV)- amount of air that can be forcefully exhaled after a normal tidal volume exhalation (1200ml) Residual volume- volume remaining in the lungs after a maximum expiration. Total lung capacity Inspiratory capacity Vital capacity= TV+IRV+ERV maximum volume which can be ventilated in a single breath. (restrictive disorder)

Unformatted text preview: Functional residual capacity Minute respiratory volume (MRV)- respiratory output MRV= R*tidal volume Alveolar ventilation rate (AVR)- volume per minute ventilating the alveoli AVR= Rate*Tidal volume Forced Expiration Volume (FEV1)-measurement of an exhaled breath in the first second (obstructive disorders) Arteriovenous oxygen difference Barometric pressure Boyle’s law – the volume and pressure of a gas are inversely proportional Dalton’s law- of partial pressures states that the partial pressure of a gas in a mixture is calculated by multiplying the fraction occupied by the gas time the total pressure of the mixture...
