vital capacity

Examples of vital capacity in the following topics:

• Lung Capacity and Volume

  • Lung volumes and capacities refer to phases of the respiratory cycle; lung volumes are directly measured while capacities are inferred.
  • The two most often used measurements are FVC (forced vital capacity) and FEV1 (forced expiratory volume in one second).
  • Vital Capacity (VC) is the maximum amount of air that a person can exhale after inhaling as much air as possible.
  • The most widely used diagnostic application for lung capacities is the ratio between forced expiratory volume (FEV1) and forced vital capacity (FVC).
  • Differentiate among tidal volume, inspiratory reserve volume, expiratory reserve volume, and vital capacity of lungs

• Asbestos-Related Diseases

  • This manifests as a reduction in lung volumes, particularly the vital capacity (VC) and total lung capacity (TLC).

• Amyotrophic Lateral Sclerosis

  • As the diaphragm and intercostal muscles (rib cage) that support breathing weaken, measures of lung function such as forced vital capacity and inspiratory pressure diminish.

• Chronic Obstructive Pulmonary Disease (COPD)

  • Spirometry also measures the forced vital capacity (FVC), which is the greatest volume of air that can be breathed out in a whole, large breath.

• Introduction to Blood Pressure

  • Blood pressure is a vital sign, reflecting the pressure exerted on blood vessels when blood is forced out of the heart during contraction.
  • Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs.
  • Blood pressure and pulse, or the vital signs, are measured as indicators of several aspects of cardiovascular health.

• Sodium, Electrolytes, and Fluid Balance

  • Electrolytes play a vital role in maintaining homeostasis within the body.
  • Electrolytes play a vital role in maintaining homeostasis within the body.

• Functions of the Diencephalon

  • Distinct parts of diencephalon perform numerous vital functions, from regulating wakefulness to controlling the autonomic nervous system.
  • The hypothalamus performs numerous vital functions (e.g., regulation of certain metabolic processes), most of which relate directly or indirectly to the regulation of visceral activities by way of other brain regions and the autonomic nervous system.

• Oxygen Transport

  • Hemoglobin is the primary transporter of oxygen with an oxygen binding capacity between 1.36 and 1.37 ml O2 per gram Hgb.
  • It has an oxygen binding capacity between 1.36 and 1.37 ml O2 per gram Hgb.
  • This also means that the approximate carrying capacity for oxygen in hemoglobin has been reached and excess oxygen won't go into hemoglobin.
  • The carrying capacity can be increased if more hemoglobin is added to the system, such as through greater red blood cell generation in high altitude, or from blood transfusions.

• Pelvimetry

  • Cephalo-pelvic disproportion (CPD) exists when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal.
  • Transverse diagonal measurement has been proposed as a predictive method to determine pelvic capacity.

• Functions of the Brain Stem

  • The brainstem regulates vital body functions such as cardiac and respiratory functions and acts as a vehicle for sensory information.
