Other general symptoms and signs (R68)

Clinical Information for Other general symptoms and signs (R68)

Chills - The sudden sensation of being cold. It may be accompanied by SHIVERING.

Air Pressure - The force per unit area that the air exerts on any surface in contact with it. Primarily used for articles pertaining to air pressure within a closed environment.

Anthropogenic Effects - Environmental alterations resulting from human activities.

Arterial Pressure - The blood pressure in the ARTERIES. It is commonly measured with a SPHYGMOMANOMETER on the upper arm which represents the arterial pressure in the BRACHIAL ARTERY.

Atmospheric Pressure - The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned.

Atrial Pressure - The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).

Blood Pressure - PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS.

Blood Pressure Monitors - Devices for continuously measuring and displaying the arterial blood pressure.

Central Venous Pressure - The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.

Cerebrospinal Fluid Pressure - Manometric pressure of the CEREBROSPINAL FLUID as measured by lumbar, cerebroventricular, or cisternal puncture. Within the cranial cavity it is called INTRACRANIAL PRESSURE.

Cerebrovascular Circulation - The circulation of blood through the BLOOD VESSELS of the BRAIN.

Financial Stress - Stress arising from personal financial concerns. (https://www.cancer.gov/publications/dictionaries/cancer-terms/def/financial-stress).

Gravity Suits - Double-layered inflatable suits which, when inflated, exert pressure on the lower part of the wearer's body. The suits are used to improve or stabilize the circulatory state, i.e., to prevent hypotension, control hemorrhage, and regulate blood pressure. The suits are also used by pilots under positive acceleration.

Hydrostatic Pressure - The pressure due to the weight of fluid.

Intracranial Hypertension - Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.

Intracranial Pressure - Pressure within the cranial cavity. It is influenced by brain mass, the circulatory system, CSF dynamics, and skull rigidity.

Intraocular Pressure - The pressure of the fluids in the eye.

Maximal Respiratory Pressures - A respiratory function test that includes the maximal inspiratory pressure and maximal expiratory pressure. It is determined by SPIROMETRY that measures the patient's RESIDUAL VOLUME and TOTAL LUNG CAPACITY and assesses the strength of RESPIRATORY MUSCLES.

Osmotic Pressure - The pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. It is proportional to the osmolality of the solution.

Partial Pressure - The pressure that would be exerted by one component of a mixture of gases if it were present alone in a container. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)

Peer Influence - The effect or sway that a PEER GROUP exerts on the beliefs, value systems and behavior of each member of a group. The social expectations for individuals to conform to peer group influence is known as peer pressure.

Pneumocephalus - Presence of air or gas within the intracranial cavity (e.g., epidural space, subdural space, intracerebral, etc.) which may result from traumatic injuries, fistulous tract formation, erosions of the skull from NEOPLASMS or infection, NEUROSURGICAL PROCEDURES, and other conditions.

Pneumothorax - An accumulation of air or gas in the PLEURAL CAVITY, which may occur spontaneously or as a result of trauma or a pathological process. The gas may also be introduced deliberately during PNEUMOTHORAX, ARTIFICIAL.

Population Dynamics - The pattern of any process, or the interrelationship of phenomena, which affects growth or change within a population.

Portal Pressure - The venous pressure measured in the PORTAL VEIN.

Positive-Pressure Respiration - A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange.

Pressure - A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)

Pressure Ulcer - An ulceration caused by prolonged pressure on the SKIN and TISSUES when one stays in one position for a long period of time, such as lying in bed. The bony areas of the body are the most frequently affected sites which become ischemic (ISCHEMIA) under sustained and constant pressure.

Pulmonary Wedge Pressure - The blood pressure as recorded after wedging a CATHETER in a small PULMONARY ARTERY; believed to reflect the PRESSURE in the pulmonary CAPILLARIES.

Transducers, Pressure - Transducers that are activated by pressure changes, e.g., blood pressure.

Vapor Pressure - The contribution to barometric PRESSURE of gaseous substance in equilibrium with its solid or liquid phase.

Venous Pressure - The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.

Ventricular Pressure - The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., DOPPLER ECHOCARDIOGRAPHY). The information is useful in evaluating the function of the MYOCARDIUM; CARDIAC VALVES; and PERICARDIUM, particularly with simultaneous measurement of other (e.g., aortic or atrial) pressures.

Body Odor - Strong or unusual odor related to the body. Occasional abnormal body odor may be a temporary effect of a metabolic change.

Cri-du-Chat Syndrome - An infantile syndrome characterized by a cat-like cry, failure to thrive, microcephaly, MENTAL RETARDATION, spastic quadriparesis, micro- and retrognathia, glossoptosis, bilateral epicanthus, hypertelorism, and tiny external genitalia. It is caused by a deletion of the short arm of chromosome 5 (5p-).

Crying - To utter an inarticulate, characteristic sound in order to communicate or express a feeling, or desire for attention.

Veins - The vessels carrying blood away from the CAPILLARY BEDS.

Peer Group - Group composed of associates of same species, approximately the same age, and usually of similar rank or social status.

Portal Vein - A short thick vein formed by union of the superior mesenteric vein and the splenic vein.

Shivering - Involuntary contraction or twitching of the muscles. It is a physiologic method of heat production in man and other mammals.
