Ch.14 Flashcards
Hypotension
decrease of systolic pressure and diastolic pressures below normal.
Another word for fever
Febrile or pyrexia
Hyperventilation
Rate and depth of respirations increase
Vasodilation
Widening of blood vessels
Bradycardia
Pulse rate less than 60 beats per minute for an adult.
Hypertension
140/90 mm Hg for two or more readings
Tachypnea
Rate of breathing abnormally rapid
Hypothermia
Decreased body temperature
Apnea
No respirations for several seconds
Bradypnea
Rate of breathing abnormally slow
Eupnea
Normal breathing
Auscultatory gap
Temporary disappearance of sounds between korotkoff sounds
Diaphoresis
visually evident perspiration, usual on forehead, upper chest, and arms. Body temps lowers diaphoresis.
Antipyretics
drugs that reduce a fever.
afebrile
when the temperature breaks and becomes an acceptable range.
Vital signs are recorded where?
On a graph or flow sheet.
Decreasing hemoglobin levels will __ respiratory rate?
increase
The expected SpO2 level is?
greater than 90%.
Heat stroke
a dangerous heat emergency, defined as body temperature of 104 F degrees or more; dizziness, confusion, delirium, excess thirst, nausea, muscle cramps and visual disturbances.
Tachycardia
abnormally elevated heart rate more than 100 beats per min.
Dysrhythmia
abnormal rhythm (a regular interval interrupted by an early beat, late beat or missed beat.
Pulse deficit
An inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse site. *ask colleague to asses the radial pulse while you asses the apical rate, compare rates, and if there is a difference you have found a pulse deficit. Frequently associated with dysrhythmias.
Adult heart/pulse rate?
60-100 beats per min.
Pulse pressure
the difference between the systolic and diastolic pressure. EX 120/80 mmHg = 40 mmHg
Orthostatic hypertension
occurs when changing positions from lying down to standing up; blood vessels are already constricted or unable to constrict; volume deficit from decreased blood volume, dehydration or blood loss, prolonged bed rest, anemia or anti hypersensitive medications.
Perfusion
the distribution of red blood cells to and from the pulmonary capillaries.
Ventilation
the mechanical movement of oxygen and carbon dioxide between the alveoli and red blood cells. *asses ventilation by determining respiratory rate, respiratory depth, and respiratory rhythm.
How do you asses perfusion and diffusion?
by determining oxygen saturation.
breath per min normal adult range?
12-20 breaths per/ min
