Define Open Pneumothorax
- air pressure in the pleural space equals barometric pressure
- b/c air that is drawn into the pleural space during inspiration is forced back out during expiration
Hypoxemia and cyanosis are generally caused by
- lesions that cause right ventricular outflow tract obstruction
- defects involving mixing of saturated and unsaturated blood
- transposition of the great arteries
- deoxygenated blood flowing into systemic circulation
indicates there was trauma to the chest resulting in the collapse of the lung
Secondary pneumothorax
artery travels in the coronary sulcus between the left atrium and the left ventricle?
Circumflex
caused by cell death and necrosis secondary to trauma or pressure-induced oxygen deficiency

Cyanosis definition
- bluish discoloration of the skin & mucous membranes,
- caused by increasing amounts of desaturated or reduced hemglobin in the blood.
A 42 year old female presents with dyspnea, rapid, shallow breathing, inspiratory crackles, decreased lung compliance, and hypoxemia. tests reveal a fulminate form of respiratory failure characterized by acute lung inflammation and diffuse alveolocapillary injury.
