25
pulse pressure
difference between systolic and diastolic pressures (should be between 30-50mmHg)

27
systole
S1, when the ventricles are at maximal contraction (lub)
28

32
what are 5 factors that affect pulse rate?

33
define tachycardia
>100 BPM
34
define elevated pulse
90-99BPM
35
define bradycardia
36
define a bounding pulse
hyperkinetic or strong pulse, does not "fade out", documented as a 3+, 4+ in terms of pulse amplitude
37
diaphargmatic respiration
occurs when diaphragm is contracted (eupnea)
38
abdominal respiration
same as diaphragmatic, occurs when diaphragm is contracted, expansion of the abdomen, rather than chest
39
thoracic respiration
achieved using intercostal muscles, breathing into the chest
40
hyperapnea
increase rate, increased depth
41
apnea
absence of respiration
42
Cheyne-Stokes respiration
periodic breathing, increased AND decreased rate and depth with periods of apnea. brain damage, drug-induced respiratory compromise
43
tachypnea
persistant RR >20/min
44
bradypnea
RR>12
45
hyperventilation
can be due to tachyapnea or hyperpnea (increased rate, increased depth)
46
hypopnea
abnormal, shallow respirations
47
paradoxic breathing
lower thorax is drawn in during inspiration, lower thorax is let out during expiration (may occur w/ negative intrathoracic pressure, or in the event of upper airway obstruction)
48
Kussmaul breathing
deep, labored, rapid breathing, type of hyperpnea, associated with metabolic acidosis
49
what type of breathing is associated with metabolic acidosis?

what are some words that are used to describe visceral nocicpetive pain?
dull, squeezing, deep, sickening
71
define neuropathic pain and name the two different types

72
define central neuropathic pain
neuropathic pain associated with damage to the CNS (e.g. phantom limb pain)
73
define peripheral neuropathic pain
