Q

do not give COPD patients O2 greater than ____ because_____

A

> 2 lpm
because poor gas exchange
–body accommodate
–a stimulus to breathe ( high CO2 ) goes away which means lower O2 > will cause resp rate to drop > CO2 narcosis/toxicity

Q

low-dose o2 for chronic bronchitis

A

normally, low O2 sends a signal to baroreceptors to prevent CO2 fr accumulating

high dose will prevent that pathway and will try to increase CO2 retention.

low dose won’t interfere w the pathway

25
normal lung sounds
1 vesicular 2 bronchial 3 bronchovesicular
26
vesicular
low pitch, soft | -peripheral lung
27
bronchial
loud, high pitch | -trachea, larynx
28
bronchovesicular
medium pitch, blowing sounds | -major bronchi
29
adventitious lung sounds
- extra breathing - wheezing - crackles - rhails
30
crackles
air passing thru fluid
31
wheeze
air passing thru constriction (may be due to swelling, narrowing, secretion, tumor) -musical
32
lub
beginning of systole | S1
33
dub
end of systole, beginning of diastole, relaxation of ventricles S2
34
spirometer is used for...
preventing atelecstatis and pneumonia
35
administering cardiopulmonary resuscitation
CAB chest compression (check pulse, if none, initiate compressions) airway (tilt head lift chin, check breathing, resp tract must be open) breathing victim d defribillation apply AED asap
36
chest physiotherapy is great for patients w sputum such as
cystic fibrosis
37
Respiratory Rate | INFANTS
20-40 breaths/min
38
``` Respiratory Rate Early Child (1-5) ```
25-32 breaths/min
39
``` Respiratory Rate Late Child (6-12) ```
18-26 breaths/min
40
Respiratory Rate | Adult
12-20 breaths/min
41
``` Respiratory Rate Older Adults (65+) ```
16-24 breaths/min
42
Pursed-lip breathing and its effect
``` 1 Slows + prolongs expiration 2 DECR airway narrowing 3 Prevents collapse of sm airways 4 Improved airways 5 DECR dyspnea 6 relaxation/decr panic ```
43
pursed lip breathing is for
1 COPD 2 dyspnea 3 anxiety attx
44
how to perform pursed lip
1 Sit upright 2 Inhale thru nose while counting to 3 3 Exhale slowly + evenly thru pursed lips while tightening abs 4 Count to 7
45
if the chest tube becomes disconnected from the drainage unit...
submerge the end in water to create a water seal (air can escape) until a new drain unit can be attached. -This is done instead of clamping to prevent another pneumothorax
46
illnesses that may cause crackles
congestive HF, fluid overload, pneumonia, bronchitis
47
Na normal range
135 - 145 mEq/L
48
K normal range
3.5m- 5.0 mEq/L
49
Ca normal range
9-10.5 total serum
50
Cl normal range
96-106 mEq/L
51
hyperkalemia on heart
bradycardia
52
relationship of calcium + phosphate
INVERSE
53
relationship of magnesium + potassium
DIRECT
54
HYPOcalcemia vs HYPERcalcemia
HYPO=incr muscular excitability HYPER=decr musc excite
55
HYPOmanesemia vs HYPERmagnesemia
HYPO=incr muscular excitability HYPER=decr musc excite
56
Biot’s
abnormal pattern of breathing characterized by groups of regular deep inspirations followed by regular or irregular periods of apnea.
57
Kussmaul
Deep, rapid breathing (hyperventilation) | -Expels co2 in DKA to fix acidosis
58
Oxygen use at home
- No petroleum - No synthetic fabrics like polyester - No wool - Wear cotton
59
wheezes can be heard in
asthma, tumors, buildup in secretion
60
COPD requires a ______ diet
high protein + high calorie | 1.9-2.9L water
61
water intake for patients w heart failure and hyponatremia
1.5L water
62
Chest tube
used to suction pleural space - fluid (pleural effusion) - air (pneumothorax) - blood (hemothorax)
63
Chest tube locations
air is higher in the chest | fluid is lower because it settles at bottom of lungs
