Blowing
Blowing
Blowing (/ˈbloʊɪŋ/), from the Old English blāwan, is the act of creating a current of air by expelling it through the mouth. It is a common action in various medical procedures and tests.
Medical Usage
In the medical field, blowing is often used in a variety of diagnostic tests and therapeutic procedures. Some of these include:
- Spirometry: A common pulmonary function test where the patient is asked to take a deep breath and then blow into a device as hard as possible. This test measures how much and how quickly you can move air out of your lungs.
- Peak Flow Meter: A device used to measure how well air moves out of your lungs. During an asthma attack, the airways in the lungs usually narrow. This device allows for early detection and management of asthma.
- Cardiopulmonary Resuscitation (CPR): A life-saving technique that combines chest compressions and blowing air into the mouth to help a person start breathing again and restore blood circulation.
- Respiratory Therapy: A healthcare profession where therapists teach patients how to improve their breathing. They may teach a patient exercises involving blowing to increase lung capacity, improve endurance, and promote better breathing.
Etymology
The term "blowing" comes from the Old English blāwan, which means "to blow, breathe, make an air current; kindle; inflate; sound a wind instrument". It is related to the Old High German blāen, the Dutch blazen, and the German blasen.
