A/a Gradient 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"

Is A/a Gradient safe for my device?

Open up

Yes, A/a Gradient follows the Google Play content guidelines to ensure safe use on your Android device.

What is an XAPK file, and what should I do if the A/a Gradient I downloaded is an XAPK file?

Open up

A file with .xapk extension is a compressed package file. It is a container file format that incorporates APK and additional associated files required for the installation. The XAPK format was introduced to package the APK file and OBB file together for a seamless delivery and installation process. XAPK format can help reduce the package size of application. On mobile phones, users need to install the XAPK installer first, and then install XAPK files through that installer. You can find the installer here:https://apkcombo.com/how-to-install/. But on PC client, you just need to put the file on LDPlayer.

Can I play A/a Gradient on my computer?

Open up

Yes, you can play A/a Gradient on your computer by installing LDPlayer, an Android emulator. After installing LDPlayer, simply drag and drop the downloaded APK file into the emulator to start playing A/a Gradient on PC. Alternatively, you can open the emulator, search for the game or app you want to play, and install it from there.
