This spirometer, built by Geoffrey Kaye for demonstration purposes, features a large, rectangular panel of wood with a wooden needle and a dial numbered from 000 to 3000 in increments of 100, which would have measured a patient's lung capacity as they breathed into a tube which is no longer present. The panel is attached to a wooden frame, which also supports a red Stenco brand pulley attached to a metal canister and a counterweight. There are two taps on the bottom of the canister. There is an elongated U-shaped glass tube affixed to a wooden plank to the right of the canister, beneath the pulley.spirometer, spirometry, machine, diagnostic machine, diagnostic machinery, respiration, lung capacity, tidal lung capacity, geoffrey kaye
