When the ratio gets above or below 0.8, it is considered abnormal ventilation-perfusion coupling, also known as a ventilation–perfusion mismatch. [3] Lung diseases, cardiac shunts, and smoking can cause a ventilation–perfusion mismatch that results in significant symptoms and diseases; treatments include bronchodilators and oxygen therapy.
In respiratory physiology, the ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the ventilation-perfusion coupling and thus the matching of two variables: V – ventilation – the air that reaches the alveoli; Q – perfusion – the blood that reaches the alveoli via the capillaries
This is a list of games for the PlayStation 5. Physical games are sold on Ultra HD Blu-ray and digital games can be purchased through the PlayStation Store. The PlayStation 5 is backwards compatible with all but six PlayStation 4 games. [1] This list only includes games that are released natively for PlayStation 5. PlayStation VR2 and backwards ...

This is a non-diffusing subcategory of Category:PlayStation 5 games. It includes titles that can also be found in the parent category, or in diffusing subcategories of the parent. This category is for games that have been or will be released exclusively on the PlayStation 5 .
The ventilation/perfusion ratio (V/Q ratio) is higher in zone #1 (the apex of lung) when a person is standing than it is in zone #3 (the base of lung) because perfusion is nearly absent. However, ventilation and perfusion are highest in base of the lung, resulting in a comparatively lower V/Q ratio.
The game began development in 2016, and was announced through a demo released on itch.io a year later. [5] This demo was very well received by users, surpassing 100,000 downloads on the platform. The studio continued with the development of the video game and finally in 2021 announced its launch for PC through a trailer.
Ventilation Scan is abnormal but perfusion scan is normal indicating abnormal airway suggesting COPD or asthma. Ventilation Scan is normal but perfusion is abnormal indicating any obstruction to the blood flow (perfusion), may be because of the pulmonary embolism obstructing the flow. Both scans are abnormal. It may be found in pneumonia or COPD.
