  1. Afebrile
    Normal body temperature in a patient ( orally ranges between 36.5 C/97.6 F and 37.5 C/99.6 F).
  2. Core temperature
    The temperature inside the body (remains relatively constant).
  3. Tachycardia
    Fast heart rate ( Adult pulse rates above 100 bpm).
  4. Bradycardia
    Abnormally slow pulse rate ( in adults, a pulse rate below 60 bpm).
  5. Tidal Volume
    The amount of air moving in and out with each breath.
  6. Pulse deficit
    When some of the ventricular contractions do not perfuse, a difference exists between the apical and peripheral pulses.
  7. Tachypnea
    An abnormally fast respiratory rate ( usually above 20 breaths per minute in the adult).
  8. Bradypnea
    Is an abnormally slow respiratory rate ( usually less than 12 breaths per minute in the adult).
  9. Apnea
    The absence of respiration's, is often described by the length of time in which no respirations occur ( e.g., a 10-second period of apnea).
  10. Eupnea
    Refers to normal respiratory rhythm and depth.
  11. Dyspnea
    Describes respiration's that require excessive effort.
  12. Stridor
    Is a harsh inspiratory sound that may be compared to crowing. It may indicate an upper airway obstruction.
  13. Wheezing
    Is a high pitched musical sound. It is usually heard on expiration but may be heard on inspiration. It is associated with partial obstruction of the bronchi or bronchioles, as in asthma.
  14. Blood pressure
    Is the force that blood exerts against the walls of the blood vessels.
  15. Systolic Blood Pressure
    The blood pressure measured during ventricular contraction ( cardiac systole).
  16. Diastolic blood pressure
    During ventricular relaxation (cardiac diastole), blood pressure is due to elastic recoil of the vessels the pressure is measured.
  17. Pulse pressure
    The mathematical difference between the measured systolic and diastolic blood pressures.
  18. Stroke Volume
    The amount of blood each ventricle pumps with each heart beat.
  19. Biot's
    Cyclic breathing pattern characterized by shallow breathing alternating with periods of apnea.
  20. Cheyne-Stokes
    Cyclic breathing pattern characterized by periods of respirations of increased rate and depth alternating with periods of apnea.
  21. Kussmaul
    Increased rate ( about 20 beats/min) and depth of respirations.
  22. Autonomic Nervous system
    Influences heart rate, cardiac contractility, systemic vascular resistance, and blood volume.
  23. Paradoxical blood pressure
    Exaggerated decreases in systolic blood pressure with inspiration.
  24. Korotkoff sounds
    5 distinct phases when deflating the bp cuff
  25. Auscultatory gap
    Is the absence of Korotkoff sounds between phases I and II.
  26. Hypertension
    The condition in which blood pressure is chronically elevated.
  27. Prehypertension
    For adults of any age, with a blood pressure between 120/80 and 139/89 mm Hg.
  28. Hypotension
    Is blood pressure below 100/60 mm Hg.
  29. Orthostatic hypotension
    Inadequate reflex composition upon position change.
