a patient was admitted to the hospital because of hypoxia and shortness of breath. his hemoglobin was 7.4 and has a history of 

cerebral vascular accident due embolism to cerebral artery. Atrial fibrillation, primary osteoarthritis of both knees, postherpetic neuralgia, ovarian cyst, degenerative disc disease, urge incontinence of urine, dyspnea on excursion.

what is the pathophysiology of hypoxia (on a cellular level) and how his medical history contributed to developing hypoxia?

The pathophysiology of hypoxia refers to a situation in which the body tissues do not receive enough oxygen supply. It means that the body tissues are starved of oxygen supply

Step-by-step explanation

Hypoxia intercedes cell injury and can lead to the death of cells through oxidative stress, acidosis, inflammation, and apoptosis which contributes to the end of cells

The cerebral vascular accident may be caused by a leaking artery or a blocked artery.

Atrial fibrillation influences the atrial up-regulation of hypoxic.

Primary osteoarthritis of both knees leads to a low supply of oxygen in the body tissues.

Postherpetic neuralgia dysphonia on excursion also leads to an inadequate supply of oxygen in the blood tissues.

The medical history lowered the supply of oxygen to the blood tissues leading to hypoxia.
