2. Acknowledgement, I would like to express my special thanks of gratitude to our director (Amirak sir),Chaiman(Mrs Santosh mam) and my teacher(Vishal sir) as well as our school (NALANDA HERITAGE SCHOOL) who gave me the golden opportunity to do this wonderful project on the topic (Oximeter and RT-PCR Test) which also helped me in doing a lot of research and I came to know about so many new things ian really thankful to them.This project would not have been completed without their enormous help and worthy experience.Their suggestion and instruction have served as the major contributor toward the completion of the project. Secondly I would also like to thanks my parents and friends who helped me a lot in finalizing this project within the limited time frame. Date-18/07/2021

3. What is oximeter ▶ Oximeter measures how much oxygen is in someone’s blood. It is a small device that clips onto a finger, or another part of the body. They are used often in hospitals and clinics and can be bought to use at home. ▶ If someone has COVID-19, a pulse oximeter may help them keep watch over their health and to know if they need medical care. However, while a pulse oximeter may help someone feel like they have some control over their health, it does not tell the whole story. Oxygen level measured by a pulse oximeter is not the only way to know how sick someone is. Some people may feel very sick and have good oxygen levels, and some may feel OK, but have poor oxygen levels.

6. The normal oxygen reading in the human body is usually between 95 and 100. However, your readings may vary depending on your exercise routine, time of the day, physical activities, body posture and more. Just make sure that you are using a good device to check the readings.

7. Is it painful to use a pulse oximeter? One of the biggest advantages of this mini device is that it is painless. So, you will not feel any discomfort while measuring blood oxygen levels. The cavity can easily fit fingers of almost all sizes. What is the normal reading in an oximeter? The normal oxygen reading in the human body is usually between 95 and 100. However, your readings may vary depending on your exercise routine, time of the day, physical activities, body posture and more. Just make sure that you are using a good device to check the readings.

8. Which finger is the best for a pulse oximeter? The index finger is usually said to be the best one for ensuring accurate readings while using a pulse oximeter. However, for medical needs, doctors and medical staff might check using other fingers as well in some cases. Avoid having too long nails or nail paint while checking your blood oxygen levels.Which Who can use a pulse oximeter in India? A pulse oximeter can be used by people of almost all age groups. The only condition behind it is that the finger must fit in the cavity of the fingertip pulse oximeter. Most of these devices do not need an expert to operate and can easily be used at home .

9. RT-PCR Test(Reverse transcription polymerase chain reaction ):- Reverse transcription polymerase chain reaction is a laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction. It is primarily used to measure the amount of a specific RNA. A PCR test for COVID-19 is a test used to diagnosis people who are currently infected with SARS-CoV-2, which is the coronavirus that causes COVID-19. The PCR test is the “gold standard” test for diagnosing COVID-19 because it’s the most accurate and reliable test.

10. Who should get tested for COVID-19? If you have symptoms of COVID-19. If you have been within six feet of someone for 15 minutes or more who has tested positive for Covid-19. (Note: some testing sites don’t offer testing if you’ve been exposed but don’t have symptoms) The nose swab PCR test for COVID-19 is the most accurate and reliable test for diagnosing COVID-19. A positive test m e a n s y o u l ik el y h a v e C O V I D -19 . A ne g a t i v e t e st m e a n s y o u probably did not have COVID-19 at the time of the test. Get tested if you have symptoms of COVID-19 or have been exposed to someone who tested positive for COVID-19.

11. How does a COVID-19 PCR test work There are three key steps to the COVID-19 PCR test: 1) sample collection 2) extraction, and 3) PCR. Sample Collection:-Sample collection is done using a swab to collect respiratory material found in your nose. A swab contains a soft tip on a long, flexible stick that is inserted into your nose. There are different types of nose swabs including nasal swabs that collect a sample immediately inside your nostrils and nasopharyngeal swabs that go further into the nasal cavity for collection. Either type of swab is sufficient for collecting material for the COVID-19 PCR test. After collection, the swab is sealed in a tube and then sent to a laboratory. When a laboratory technologist receives the sample, they perform a process called e x t r a c t io n , w h ic h i s o l a t e s g e ne t i c m at e r i a l f r o m t h e s a m p l e i n c lu d i n g g e ne t i c material from any virus that may be present. The PCR step then uses special chemicals and a PCR machine, called a thermal cycler, which cause a reaction to occur that makes millions of copies of a small portion of the SARS-CoV-2 virus’s genetic material. During this process, one of the chemicals produces a fluorescent light if SARS-CoV-2 is present in the sample. This fluorescent light is a “signal” that is detected by the PCR machine and special software is used to interpret the signal as a positive test result.

12. What do COVID-19 PCR test results mean? A positive test result means that it is very likely that you have COVID-19. Most people have mild illness and can recover safely at home without medical care. Contact your healthcare provider if your symptoms get worse or if you have questions or concerns. A negative test result means you probably didn’t have COVID-19 at the time you took your test. However, it is possible to be infected with SARS-CoV-2 but not have enough virus in your body to be detected by the test. For example, this may happen if you recently became infected but you don’t have symptoms, yet; or it could happen if you’ve had COVID-19 for more than a week before being tested. Keep in mind that a negative test doesn’t mean you are safe for any length of time. You can be exposed to COVID-19 after your test, get infected and spread the SARS-Cov-2 virus to others.

13. What are the advantages of a COVID-19 PCR test? The main advantages of COVID-19 PCR test are its accuracy and reliability. It is the most accurate test available for COVID-19 detection. Are there downsides to a COVID-19 PCR test? Because the test is able to detect very small amounts of virus material, it can continue to detect fragments of SARS- CoV-2 virus even after you’ve recovered from COVID-19 and are no longer contagious. So you may continue to test positive if you have had COVID-19 in the distant past, even though you can’t spread the SARS-CoV-2 virus to others.
