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?
97.6-100
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)
-temporal
-infrared
-rectal (1° higher than oral)
