Jonathan Vrban is a medical professional who has handled workplace safety and workers' compensation issues. Jonathan Vrban is well-versed in interpreting the results of a variety of diagnostic procedures, such as spirometry.
Spirometry is a common test for measuring an individual’s lung capacity. It is often used to determine the presence or degree of respiratory illnesses, including COPD, pulmonary fibrosis, asthma, chronic bronchitis, or emphysema. Doctors also use spirometry tests to determine the effectiveness of medications on these conditions.
A spirometry test, which lasts about 15 minutes, involves breathing into a tube attached to a device that measures airflow. Patients are generally seated, with their nostrils clipped shut. The person administering the test will instruct the patient to inhale deeply and then blow out as strongly as possible. In order to obtain reliable results, patients must keep their lips tightly sealed around the tube while exhaling.
The doctor interpreting the test results generally requires three similar results close together in time to ensure accuracy. If there are significant discrepancies, the patient may have to repeat the test. The top reading out of three comparable attempts is considered the final result. Doctors trying to determine whether medication will improve a patient’s breathing may obtain an initial result, administer a bronchodilator, repeat the test a little later, and compare the two outcomes.
An avid cook in his free time, Dr. Jonathan “Jon” Vrban is currently involved in writing cookbooks and making videos to promote his recipes. Dr. Jonathan Vrban strives to optimize the quality of his videos for the benefit of his online viewers.
Home videographers know that a professional appearance plays a key role in positive audience response. The home videographer does not need advanced equipment to do so, however; he or she simply needs a plan and a well-thought-out shot list. Good shot lists allow the videographer to vary the angle and focus of the shots and to emphasize closer shots, which give a video an air of professionalism.
Professional-looking video also requires good sound, so the home videographer should know how to check sound levels. Headphones make it easier for the person holding the camera to monitor the incoming audio. Good lighting is also essential; any indoor shots should involve as much natural light as possible, as well as external light when necessary. This keeps the image clear and improves contrast. Finally, the videographer should have a command of editing software or in-camera editing functions that will enable him or her to execute fades, cut-aways, and other elements that add visual interest.
Jonathan Vrban, who currently lives in Hawaii, enjoys spending his free time cooking and gardening. In addition to participating in these and other activities, Jonathan (Jon) Vrban is interested in blogging and posting cooking videos to the Internet.
While the Internet is a great resource, particularly for those who want to explore a new hobby, it is important to keep in mind that not everything posted online is true and accurate. For many people, determining the truthfulness or reliability of online information can be difficult. When deciding whether or not to trust something on the Internet, there are a number of things a person should keep in mind.
First of all, check the source links for online articles or blog posts. Webpages often include a link that a person can use to determine where the information on the page originated. By reading the information on the source page, an Internet user can get a better idea of the type of information that is being presented. In particular, it can help the reader determine whether or not the information is a fact, or just one person’s opinion.
Finally, be aware of anecdotal evidence a person might use the back up an idea. This type of evidence is generally not reliable, since it is based off one person’s unique perception or impression of an event or idea. More reliable information can be backed up or proved by hard evidence, not anecdotes.
