Complete obstruction of the airway represents a medical emergency. During such crisis, caretakers may attempt back blows, abdominal thrust, or the Heimlich maneuver to dislodge the inhaled object and reestablish airflow into the lungs. [21]
A resuscitative thoracotomy is indicated when severe injuries within the thoracic cavity (such as hemorrhage) prevent the physiologic functions needed to sustain life.The injury may also affect a specific organ such as the heart, which can develop an air embolism or a cardiac tamponade (which prevents the heart from beating properly).
The term pulmonary edema literally means wet lungs. This term actually refers to a pathological condition of the lungs, frequently demonstrated by chest X-ray. Edema of the lungs should be thought of as the result of a disease such as congestive heart failure and not a disease in and of itself. In this case it would be a cardiac disease and not ...
Many official guides recommend continuing a cardiopulmonary resuscitation until emergency medical services arrive (for trying to keep the patient alive, at least). [26] The same guides also indicate asking for any emergency defibrillator (AED) near, to try an automatic defibrillation as soon as possible before considering that the patient has died.
In contrast, tension pneumothorax is a medical emergency and may be treated before imaging – especially if there is severe hypoxia, very low blood pressure, or an impaired level of consciousness. In tension pneumothorax, X-rays are sometimes required if there is doubt about the anatomical location of the pneumothorax. [16] [18]
Subcutaneous emphysema can be caused by medical procedures and medical conditions that cause the pressure in the alveoli of the lung to be higher than that in the tissues outside of them. [4] Its most common causes are pneumothorax or a chest tube that has become occluded by a blood clot or fibrinous material.

Normal atmospheric air contains approximately 21% oxygen when inhaled. After gaseous exchange has taken place in the lungs, with waste products (notably carbon dioxide) moved from the bloodstream to the lungs, the air being exhaled by humans normally contains around 17% oxygen. This means that the human body utilises only around 19% of the ...
