What should you know about Koko Legend spirometer?

You breathe through a mouthpiece while the equipment records airflow. A clinician may ask you to breathe normally, take a full breath, and then exhale forcefully for as long as instructed. The readings can help assess airflow limitation and compare breathing before and after an inhaled medicine. The device does not by itself name a disease; your symptoms, examination, medical history, and test quality all affect interpretation.

Spirometry may be used when a clinician is assessing asthma, chronic obstructive pulmonary disease, persistent breathlessness, or an unexplained cough. The test can feel effortful because the result depends on a strong, well-sealed blow.

Follow the testing centre’s instructions about eating, smoking, exercise, and inhalers. Wear clothing that does not restrict your chest or abdomen. Tell the clinician if you have recently had chest pain, an operation, a respiratory infection, or trouble producing a forceful breath. During the test, keep your lips sealed around the mouthpiece and follow each breathing instruction closely; a repeat attempt may be needed if the first blow is interrupted or the seal leaks.

Arrange medical review for breathlessness that is new, worsening, or limiting ordinary activity, or for a cough that does not settle. Seek urgent help for severe difficulty breathing, blue or grey lips, fainting, confusion, or chest pressure that does not ease. A spirometry appointment should not delay emergency assessment.

Ask what the test is intended to clarify, whether you should change any inhalers beforehand, whether the results were technically reliable, and what follow-up is needed. You can also ask whether another test or a bronchodilator comparison would add useful information.
