Download A/a Gradient on PC

A/a Gradient is a Education application developed by Satish Deopujari, but with the best Android emulator-LDPlayer, you can download and play A/a Gradient on your computer.

Running A/a Gradient on your computer allows you to browse clearly on a large screen, and controlling the application with a mouse and keyboard is much faster than using touchscreen, all while never having to worry about device battery issues.

With multi-instance and synchronization features, you can even run multiple applications and accounts on your PC.

And file sharing makes sharing images, videos, and files incredibly easy.

Download A/a Gradient and run it on your PC. Enjoy the large screen and high-definition quality on your PC!

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"
