Severe chest pain that radiates to the arm or the jaw and doesn’t go away should be an emergency 911 phone call, London says. ... Chest pressure. ... Shortness of breath.
Causes may include heart failure, kidney failure, narcotic poisoning, intracranial pressure, and hypoperfusion of the brain (particularly of the respiratory center). The pathophysiology of Cheyne–Stokes breathing can be summarized as apnea leading to increased CO 2 which causes excessive compensatory hyperventilation, in turn causing decreased CO 2 which causes apnea, restarting the cycle.
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
Dyspnea can come in many forms, but it is commonly known as shortness of breath or having difficulty breathing. People presenting with dyspnea usually show signs of rapid and shallow breathing, use of their respiratory accessory muscles, and may have underlying conditions causing the dyspnea, such as cardiac or pulmonary diseases.

It is also known as expired air resuscitation (EAR), expired air ventilation (EAV), rescue breathing, or colloquially the kiss of life. It was introduced as a life-saving measure in 1950. [5] Mouth-to-mouth resuscitation is a part of most protocols for performing cardiopulmonary resuscitation (CPR) [6] [7] making it an essential skill for first ...
At rest, there is a negative intrapleural pressure. This provides a transpulmonary pressure, causing the lungs to expand. If humans didn't maintain a slightly negative pressure even when exhaling, their lungs would collapse on themselves because all the air would rush towards the area of lower pressure. Intra-pleural pressure is sub-atmospheric.
Noninvasive positive pressure ventilation is the delivery of positive pressure ventilation through a tight-fitting mask that covers the nose and mouth. It assists patients who can spontaneously breathe. Noninvasive positive pressure ventilation delivers end-expiratory pressure with a volume control setting.
