semester 2 vocab 1 Flashcards
apical pulse
the pulse felt or heard at the apex of the heart, which is the tip at the bottom of the heart
apnea
(without breathing)
a pause in breathing that can occur during sleep or in infants longer than 15-20 seconds
arrhythmia
an irregular heartbeat, when the heart beats too fast too fast, too slow, or with an irregular rhythm
aural temperature
the temperature measured in the ear canal
axillary temperature
the body temperature measured in the armpit
blood pressure
the force of blood pushing against the artery walls, and is measured in millimeters of mercury (mmHg)
bradycardia
abnormally slow heartbeat/ rate usually under 60 beats per minuet
bradypnea
abnormally slow breathing for a person’s age and activity level
character
quality of pulse or breath
Cheyne-stokes
an abnormal breathing pattern characterized by alternative periods of deep, rapid breathing (hypernea) and shallow or absent breathing (apnea)
clinical thermometers
a temperature measuring device used to measure only the body temperature
cyanosis
a bluish purple discoloration of the skin, lips, and nail beds caused by a low level of oxygen in the blood
diastolic
lower blood pressure during heart relaxation
dyspnea
difficulty breathing
electronic thermometers
digital temperature measuring device
fever
elevated body temperature
homeostasis
body’s stable internal environment
hypertension
high blood pressure
hyperthermia
abnormally high body temperature
hypotension
low blood pressure
hypothermia
abnormally low body temperature
temporal temperature
temperature measured on forehead using Infared
vital signs
key health indicators; temperature pulse, respiratory blood pressure
noncontact infrared thermometer
temperature measured without physical contact
oral temperature
temperature measured via mouth
orthopnea
difficulty breathing when laying down
pain
physical or emotional discomfort
pulse
rhythmic expansion of arteries
pulse deficit
difference between heartrate and pulse rate is that heartrate
pulse oximeter
device measuring blood oxygen levels
pulse pressure
difference between systolic and diastolic pressure
pyrexia
elevated body temperature (fever)
rales
abnormal lung sounds (crackling)
rate
speed of heartbeat or breathing
respirations
taking in oxygen and releasing carbon
rhythm
regularity of heart or breathing cycles
sphygmomanometer (sfig-mohrma-nam-en-ter)
a device for measuring blood pressure
sthethoscope
instrument for listening to body sounds
systolic
top number of a blood pressure reading which indicates arterial pressure when the heart contracts
tachycardia
rapid heart rate over 100 bpm
tachypnea
rapid breathing rate above 25 breaths per minute
temporal
temples right by the eyes in front of the ear
wheezing
high-pitched sound during breathing often caused by obstruction
vital signs
measurable external signs that tells what’s going on inside the body
supine position
patient lies face up
skin signs
skin color, temperature, moisture and capillary refill; reflects the status of the heart, circulation and respiration
