1. too little oxygen in the inhaled air
2. inadequate ventilation (=the chest muscles and diaphragm moving air in and out of the lungs)
3. ventilation/perfusion (=blood flow) mismatch
4. Shunting (venous, unoxygenated blood flows through completely unventilated areas of the lung and mixes with oxygenated blood from functional areas of the lung going into the body - a severe form of no. 3, which doesn't improve much by giving oxygen)
5. inadequent diffusion of oxygen and carbon dioxide across the membrane between the air-filled alveoli and the blood (as in severe pneumonia or pulmonary edema)
(6. "venous admixure effect" does not cause, but does worsen hypoxia - when the blood flowing into the lungs contains too much carbon dioxide (CO2) for the lungs to clear, as in acute heart failure or septic shock)

∙ 15y agoA hypoxic-ischemic injury is the result of a lack of oxygen, which causes damage to brain cells and the spinal cord. This type of brain injury is most common before, during, or after childbirth, with statistics citing that two to four of 1,000 births result in hypoxic-ischemic injury. But while this type of brain injury is relatively rare, it can cause permanent brain damage and even death. Causes:
While the exact causes of hypoxic-ischemic injury are unknown, some studies have linked placenta issues, maternal blood pressure problems, maternal uterine rupture, and umbilical cord complications to the injury. Symptoms include seizures and other signs of brain damage following childbirth.

∙ 11y agoHypoxia is a medical condition in which oxygen is no longer sufficiently reaching your cells. It can be caused in a number of ways:
- If your airway is closed, such as when you're choking on food or you're drowning, your lack of breathing will cause hypoxia
- Toxins in the blood, such as carbon monoxide, can prevent blood from absorbing oxygen
- Stagnant hypoxia can result from high G-forces, such as when a fighter pilot pulls a turn or you go through a spiral in a roller coaster. This type of hypoxia specifically affects the brain
- Severe bleeding can lead to hypoxia if there isn't enough blood to transport oxygen
- Other medical conditions can cause your cells to prevent oxygen transport across the cell membrane. Genetic conditions are rare but poisons and toxins can cause this
