These are common presenting symptoms of chronic and cardiogenic pulmonary edema due to left ventricular failure. The development of pulmonary edema may be associated with symptoms and signs of "fluid overload" in the lungs; this is a non-specific term to describe the manifestations of right ventricular
Acute respiratory distress syndrome : a potentially life-threatening condition where the alveoli are damaged thereby letting fluid leak into the lungs which makes it difficult to exchange gases and oxygenate the blood. [3] It is the general practice of the medical community to use the Berlin criteria to diagnose ARDS.
Basic airway management is a concept and set of medical procedures performed to prevent and treat airway obstruction and allow for adequate ventilation to a patient's lungs. [1] This is accomplished by clearing or preventing obstructions of airways. Airway obstructions can occur in both conscious and unconscious individuals.
NPPE develops as a result of significant negative pressure generated in the chest cavity by inspiration against an upper airway obstruction. These negative pressures in the chest lead to increase venous supply to the right side of the heart while simultaneously creating more resistance for the left side of the heart to supply blood to the rest of the body ().

The alveoli of the lungs fill with edema fluid, causing dyspnoea, cough and frothy or bloodstained sputum. Gas exchange is affected, and as hypoxia increases there may be a loss of consciousness. Oxygenation in divers may be affected by breathing gas mix and partial pressure reduction due to ascent.
In the lungs, the extra fluid accumulates into the air sacs within the lung, causing difficulties in oxygen getting into the blood. This results in low blood oxygen levels and shortness of breath. In the arms and legs, the fluid accumulates in the tissues, causing swelling. This is most prominent in the legs due to the effects of gravity.
Crackles or wheezing (while breathing) in at least one lung field; Central blue skin color; Tachypnea (rapid breathing) Tachycardia (rapid heart rate) Acute mountain sickness and high altitude cerebral edema may also be present in conjunction with HAPE, however these symptoms may be subtle or not present at all.
