24
Q
type 2 failiure cause
A
- low oxygen (hypoxemia) and high carbon dioxide (hypercapnia) levels in the blood.
- The primary problem is alveolar hypoventilation, where the body is unable to adequately clear CO₂ from the blood
- COPD - emphysema and chronic bronchitis can cause airflow obstruction, leading to CO₂ retention and difficulty in exhaling enough air.
- fatigue
- kyphoscoliosis- structural problems with the chest can limit lung expansion and cause CO₂ retention.
- drigs- opiates - centeral respiratory depression impairs ventilation leading to C02 retention
- nueromuscular disorders- Conditions such as muscular dystrophy or Guillain-Barré syndrome can weaken the muscles required for breathing, resulting in inadequate ventilation.

type 1 respiratory failure causes
* low levels of oxygen (hypoxaemia) in the blood, with a normal carbon dioxide level (PaCO₂).
* It usually occurs due to ventilation/perfusion (V/Q) mismatch – the volume of air flowing in and out of the lungs is not matched with the flow of blood to the lung tissue.
**Reduced ventilation and normal perfusion**
* pneumonia- Infection in the lungs that leads to inflammation and impaired gas exchange
* pulmonary odema- Fluid in the lungs, often due to heart failure, that impairs oxygenation
**Reduced perfusion with normal ventilation**
* pulmonary embolus- A blood clot that blocks a pulmonary artery, preventing proper oxygen exchange
```
```
* pneumothorax
* acute asthma- A severe asthma attack that significantly reduces the lung's ability to oxygenate blood, often with normal or low CO₂ levels.
* acute respiratory distress syndrome- A condition characterized by widespread inflammation and fluid accumulation in the lungs, reducing oxygen absorption
* Atelectasis – Collapse of lung tissue, which can obstruct oxygenation.
* fibrosis- Interstitial lung diseases – Conditions such as pulmonary fibrosis that cause scarring of lung tissue, reducing its ability to absorb oxygen.
* COPD
* COVID
