Spirometer

Introduction

♦ Spirometer is used to measure the amount of the air that is inbreathed, breathed out and the rate that air is expelled from the lung. In anyone’s breath cycle, the amount of air inbreathed and breathed is called tidal volume. It is about 0.5L. There is extra amount of air breathed after normal breathing, which is called intake reserve and exhalation retention.

Usage

♦  Assemble the Spirometer and connect it to datalogger and computer. Open SWR iLab to create new experiment, new page and set experiment time and acquisition interval.

♦  Sit regularly or stand still when using the product. Do not look at the data being collected if possible. It will not change the way you breath subconsciously.

♦  Attach the airflow head to your lips.

♦  Pinch your nose to make sure all the air breathed out coming from your mouth if necessary (normally not necessary except the result is qualitative).

♦  Breath calmly in order to get used to the sensor when breath becomes stable. The gas exhaled from lung is positive airflow and the gas inhaled is the negative airflow.

♦  During using interval, place the Spirometer on the surface of workbench. Try to avoid the heat of your hand affecting the result.

Notes

♦  The product can only be used for teaching. Follow the local safety behavior policy when using this product. The instructor has responsibility to confirm the user has the medical history of respiratory or cardiovascular and cerebrovascular diseases.

♦  The airflow header provided contains a filter, which can filter most of virus, fungus and bacteria.

♦  Every student should only use their own airflow header to prevent cross-infection.

♦  The fixed airflow header is not required to replace every time as long as the outlet is protected by the airflow header. If the fixed airflow header is used carelessly by someone, it should be replaced immediately.

♦  When using the Spirometer, the tester should not be nervous. Teacher should make sure students under testing are healthy and has no medical history of the cardiovascular disease, or has no respiratory problems (such as asthma). The Spirometer may possibly make some testers feel uncomfortable when it is used. Calm testers as much as possible. If the tester feels really uncomfortable, stop experiment immediately.

♦  Make sure the airflow head is well sealed when it touches to user’s lips. Keep your tongue flat so that the product will not mess up with ventilation opening.

♦  Cleanliness: The outer casing can be cleaned by a soft and wet cloth and the cloth should be painted with the disinfectant at the standard medical level or the Milton hypochlorite solution (refer to the explanatory packaging on the bottle). Do not use alcohol. Otherwise it may break the plastic.

♦  In any cases, do not immerse the Spirometer or other airflow header into any cleaning solution. Do not disinfect or sterilize it with hot water, steam or hot air.

Typical experiment

♦  Measure vital capacity

Others

♦  Measure lung capacity
