Understanding Spirometers And Why Should You Use A Spirometer

What is a Spirometer?

A spirometer is a device used to measure the volume of air inhaled and exhaled by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, namely obstructive and restrictive. There are various types of spirometers which use a number of different methods for measurement (pressure transducers, ultrasonic, water gauge, etc.). A person breathes into the spirometer, forcefully and with all their strength. The spirometer then measures the amount of air exhaled by the lungs and also the speed at which it was exhaled.

It lets the user know whether there is an obstruction in the lungs or the airways. It can detect the presence of a lung disease and also lets the user know the severity of the lung disease. One should always contact a doctor based on the readings and should not assess the problem on their own.

What Does A Spirometer do?

It diagnoses certain types of lung diseases such as asthma, bronchitis, and emphysema. It is also used to find the cause of shortness of breath and measure whether exposure to chemicals at work affects lung function. It is used to check lung function before someone goes through a surgery, assess the effect of the medication, and to measure the progress of the treatment.

Why is a Spirometer Used?

A spirometer is used for the following reasons:

  • Diagnose certain types of lung disease
  • Find the causes of shortness of breath
  • Measure whether exposure to chemicals affects the lungs
  • Check lung function
  • Asssess the effect of some medications
  • Measure progress in disease treatment

Types of Siprometers

There are six different types of sprometers based on the location where they are placed and the techniques they use to measure the lung function:

  • Whole Body Plethysmograph - It gives the most accurate measurements since it is taken in an enclosed space.
  • Pneumotachometer - Determines the flow rate of gases. The best part is that the user can breathe fresh air during the test.
  • Fully Electronic Spirometer - The household spirometers these can be used to measure the basic lung function easily and without any hassle.
  • Incentive Spirometer - Used to help patient improve their lung function. Such as - AirLife Incentive Spirometer 
  • Peak Flow Meter - It is used to measure how well a person’s lungs expand.
  • Windmill-type Spirometer - It is used for measuring the forced vital capacity without using water.

What is an Incentive Spirometer?

An incentive spirometer is a device used to help patients improve the functioning of their lungs. It is given to patients who have had any surgery that might put in danger the respiratory function, particularly surgery to the lungs themselves. It is also commonly given to patients recovering from cardiac or other surgery involving extended time under anesthesia and prolonged in-bed recovery. The incentive spirometer is also issued to patients recovering from pneumonia or rib damage to help minimize the chance of fluid build-up in the lungs. It can be used as well by wind instrument players, who want to improve their air flow.

What are my Options?

There are a number of options. For example the CareFusion AirLife Airx Flow Incentive Spirometer is disposable and designed for exercising and measurement of volume flow. It helps preoperative and postoperative patients increase their lung volume by keeping the instruments inhalation-sensitive ball suspended with their inhalation. Smiths Medical Portex Flow Based Incentive Spirometer is a small hand-held tool with a breathing tube and air chamber that is used to measure the air taken into and exhaled by the lungs. It is used when recovering from surgery to help keep lungs active. Voldyne 2500 mL Incentive Spirometer is the ideal choice for patients requiring post-operative physiotherapy. It delivers a reliable measurement of inhaled lung volumes to maximize clinical outcomes. The volume measurement up to 2500 mL accommodates smaller inspired volumes. CareFusion AirLife Pediatric Volumetric Incentive Spirometer With One-Way Valve simplifies deep breathing therapy with an intuitive design that prompts patients to correctly perform and monitor their own breathing exercises, even without direct supervision. A patient goal indicator can be adjusted and allows patients to monitor their own progress.
