Vital Signs Flashcards
homeostasis
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
-The bodies “steady state” is maintained by adaptive responses that promote healthy survival
How many types of feedback mechanisms are there?
Two.
Negative
Positive
True or false
The bodies feedback processes are predominantly positive
False. Mostly negative.
Mechanisms for Homeostasis
-heartbeat
-blood pressure
-body temp
-respiratory rate
-electrolyte balance
What are the vital signs?
-body temp
-pulse rate
-blood pressure
-respiratory rate
-mental state
-sensorium
What is normal temperature?
97.7-99.9
What are normal respirations for an adult?
12-20 breaths per minute
What are normal respirations for a child?
20 to 30 breaths per minute
What is normal pulse rate for an adult?
60 to 100 BPM
What is a normal pulse rate for a child?
70 to 120 BPM
What is normal blood pressure?
Systolic lesser than or equal to 120 mmHg
Diastolic lesser than or equal to 80 mmHg
What does the negative feedback Loop do?
Reduces changes to bring body back to normal
What does a positive feedback loop do?
Increase changes until specific goal is reached (childbirth, blood clot)
What gland plays a role in preservation of heat (shivering) and regulation of heat loss (diaphoresis)
Hypothalamus
What are the different ways of measuring body temperature?
-oral
-axillary
-tympanic (close to rectal measurement)
-temporal
-infrared
-rectal (1° higher than oral)
What is the temperature that signifies hypothermia?
Below 97.6°F. It increases metabolic rate.
What is the temperature that signifies hyperthermia?
Oral temperature higher than 100°F
What is the temperature that signifies hyperthermia?
Oral temperature higher than 100°F
What is the normal respiration rate for newborns?
30 to 60
During inspiration the diaphragmatic muscles;
-move downward
-Push abdominal content
-Expand chest cavity
-Allow relaxation and air rushes in into lungs
What is normal pulse rate for a newborn?
100-160 BPM
In certain circumstances, where is the last place you can feel the pulse?
Carotid artery
During CPR, typically pulse is measured at _______________
Carotid artery
In critical care settings, pulse rate may be measured with a ___________ _____________.
Pulse oximeter
