About A/a Gradient APK
Description
The variables in this App. are :RQ :Respiratory Quotient (approx 0.8 at normal physiological state)
PB : Atmospheric pressure.(760 mm Hg at sea level.)
FiO2 : Fraction of Inspired Oxygen. (0.21 at room air.)
PAO2 : Alveolar Oxygen tension
PaO2 : Arterial oxygen tension
These can be independently changed and the reflection of these changes can be seen in the alveolar – arteriolar gradient and PaO2 / FiO2 ratio.
A-a oxygen gradient : The alveolar arterial (A–a) oxygen gradient is a measure of oxygen transfer across alveolar capillary membrane (“A” denotes alveolar and “a” denotes arterial oxygenation). It is the difference between the alveolar and arterial oxygen tension.
A-a oxygen gradient = PAO2 - PaO2.
PaO2 is derived from ABG while PAO2 is calculated.
PAO2 = (FiO2 x [PB - PH2O]) - (PaCO2 ÷ RQ)
[PH2O is the partial pressure of water (47 mm Hg)] & PaCO2 is partial pressure of Carbon di oxide in arterial blood.
A-a gradient varies with age and can be estimated from the following equation, assuming the patient is breathing room air.
A-a gradient = 2.5 + 0.21 x age in years.
A-a gradient increases with higher FiO2.
PaO2/FiO2 ratio : It is a measure of Oxygen transfer across the alveolar capillary membrane. Normal PaO2/FiO2 ratio is 300 to 500 mmHg. Values less than 300 mmHg indicating impaired gas exchange and values less than 200 mmHg indicates severe hypoxemia.
"Alveolar arterial membrane is depicted in this App. as a BLACK LINE (This is purely a conceptual representation of ventilation-perfusion relationship).The thickness of this Black Line is shown to vary depending on the variations in A-a gradient"

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
