Q

T or F
patient can lie on chest tube

Q

Arterial line
Goal
PT concern

A

ABG, hemodynamic monitoring
no hip flexion over 90 degrees (femoral)
disconnection → hemorrhage
keep the patient wrist at the right curve for good readings
if discontinued → wait for 3-6 hours before mobilizing the patient

20
Q

Increase in CVP meaning T and F
increased vascular volume
increased ventricular function
global heart failure
decreased pulmonary vascular resistance
systemic vasodilatation
positive end expiratory pressure

A

increased vascular volume
decreased R ventricular function
global heart failure
increased pulmonary vascular resistance
systemic vasoconstriction
positive end expiratory pressure

21
Q

Decrease in CVP T or F

A

hypovolemia
posture, legs lowered to the floor
with inspiration

22
Q

PICC line
goal
PT concern

A

-alternative to central venous line with less complication and can be left for months + can be done by patient
-should not lift more than 10lb with arm and avoid strenuous repetitive activity with arm
-exercise on the side of PICC not contraindicated
-don’t do a lot of movements and don’t go full ROM (caution bending elbow beyond 45 degrees

23
Q

port a cath
goal
PT concern

A

-Implanted surgically, pectoral portal + catheter
-patient can resume regular activities (exercise, swimming,…)
-avoid manual technique over device and contact sport

24
Q

Swan Ganz
Goal
Pt concern

A

measure PULMONARY ARTERY PRESSURE (directly on the heart)
ambulation not typically done, HOWever, study show no complication
- sit to stand beside bed possible
if it’s femoral you can’t mobilize and pt will be bed rest for 4-6h when its removed

25
Q

Pulmonary artery wedge (occlusion) pressure
Goal
PT concern

A

pulmonary artery catheter with BALLON INFLATED
Provide information on filling pressures of L side of heart (end diastolic L ventricular pressure: pressure of capillaries pushing blood into the pulmonary tissue)
5-12 mm hg normal
12-18 optimal filling pressur e
18-30 interstitial edema
30 and more pulmonary alveolar edema

26
Q

Nasograstric (NG) tube
goal
PT concern

A

provides nurtrition and removes gastric content
can disconnect for mobilisation
pt position never flat or head down, head of the bed elevated to 45 degrees

27
Q

What is PEG and PEJ

A

feeding tube directly to the stomach or intestin
no chest expansion limitation and the patient can eat with it

28
Q

urinary catheter ?

A

make sure its mobilize with him

29
Q

ECG purpose

A

monitor HR and find arrythmias

30
Q

Intra-aortic balloon pump
goal
PT concern

A

increase cardiac output
don’t mobilize and wait 24h before mobilize

31
Q

Epidural goal and PT concern

A

Decrease pain
be careful to hypotension

32
Q

intracranial pressure monitoring
goal + PT concern

A

measure intracranial pressure
level of the captor shouldn’t be moved (aligned with head of pt)
so if mobilize ask nurse to clamp system

33
Q

hemodialysis catheter
goal
PT concern

A

removed waist from the blood when kidney doesn’t work
can walk and stand
no manual technique on catheter

34
Q

CVVH
goal
PT concern

A

removed waist from blood when pt can’t tolerate hemodialysis
depends where the catheter is putted
if Upper body - can move in room
if Lower body - move in bed

35
Q

PAo2 and SpO2 for none hypoxemia and for severe

A

Pao2 and Spo2 none: 80-110 and 95-100
Pao2 and Spo2 severe: less than 40 (mmHg) and less than 75-80 (%)

36
Q

Nasal Cannula

A

Fio2: 24-44%
amount of Fio2 depends on pt flow rate and breathing pattern - not an exact measure
flow: 1L/min
approximative FiO2: 24%
every increase of 1L/min = 4% increase of approximative Fio2

37
Q

simple mask

A

Fio2: 40-60%
minimum flow rate: 5 - 6 L/m
not an exact measurement again same reason nasal canula

38
Q

oxymizer

A

higher fio2 than nasal canula for the same flow
24-44%
reduce o2 losses during exhalation

39
Q

non breathing mask

A

Fio2: 70-11%
flow 15L/min
best choice for emergency

40
Q

venturini mask

A

Precise measures
24 - 50%
Depends on color of piece attached

41
Q

high flow venturini mask

A

with humidity
28-98%

42
Q

optiflow FIo2
flow

A

Fio2: 30-100%
40-60 ml

43
Q

Pulse oxymeter what does it measure

A

Its a lecture of how much % of light is absorbed oxygenated vs deoxygenated hemoglobin
Spo2= blood saturation

44
Q

Factors that could influence Spo2 reading? 5

A

pulsatil measure so everything that affect perfusion of the hand could modify Spo2 measures

45
Q

Where do we take Spo2 1st choice, 2nd choice and 3rd

A

3 to 4 finger
ear lobe
forehead

46
Q

criteria of Po2 to have O2 at home?

A

Pao2 ≤ 55 mm Hg

47
Q

Criteria for nocturnal oxygen alone Spo2?

A

SpO2 < 90% for > 30% of recording time

48
Q

Benefit of of supplemental O2 short term

A

decrease dyspnea patient with COPD and ILD
increase exercise tolerance

49
Q

Benefit of of supplemental O2 long term

A

When whe give O2 is not for the lungs its for the heart
Because if desaturation below its going to make the heart work harder meaning risk of core pulmonale at long term
