Open pneumothorax

Treatment:

VTS

A

Opening through chest to allow air into pleural space. Also known as sucking chest wound.

Treatment:
Valsalva and hummm- increases thoracic pressure outside air cant get inside

Tape petroleum gauze on 3 sides 4th side acts like an airvent

Sit up to expand lungs. But Trauma clients stay flat for it to be evaluated for other injuries

Q

Chest tube is needed because

Placement of chest tube

Can both be placed?

Other placement

A

Collapsed lung

Upper anterior chest or 2nd intercostal space for air

Laterally in lower chest or 8th or 9th intercostal space for fluid/drainage

Air rises and fluid or drainage settles. Chest tube is sutured to chest wall with an AIR TIGHT DRESSING.

Yes. With y connected and attached to closed CDU( chest drainage unit )

Mid axillary one tube for air while other for drainage. Anterior chest tube is not usually used because it requires prolonged healing

Q

Drainage chamber

A

First chamber

The drainage is connected by a 6 foot tube to allow patient to move and turn around.

And if the chamber fills up, get another CDU but make sure to get one before it fills up. It usually holds 2000 mL of of fluid so it rarely gets full.

18
Q

Water seal chamber

A

Promotes one way flow out of the pleural space which prevents air from going back to pleural space.

Small tube is connected to the first chamber that allows drainage to remain in first chamber while air goes to water seal chamber.

Contains 2 cm of water which acts as one way valve

Bubbling is normal when client is coughs,sneezes or exhales.

Tidaling is normal. It is the rise and fall of water. If it stops, the lung has re-expanded.

19
Q

Suction Control Chamber

A

Third chamber.
When suction is needed, this chamber controls the amount of suction pressure applied

Sterile water is used and maintained at 20 cm.

Suction must be slow,gentle and continuous bubbling.

Pressure is not controlled by wall suction but is controlled by WATER LEVEL so always maintain prescribed water level.

20
Q

If dry suction system is used

A

There is no water therfore no bubbling.

Dial is used to control suction not the wall suction even if the wall suction is increased.

21
Q

Management priorities of closed chest drainage system

PEEP

A

Promote comfort
Ensure integrity of system
Ensure CT patency
Prevent complications

22
Q

Assessment of CDU

Dressing
Listen
Oximetry
Palpate for
Record
Notify
DBE
Wbc
Daily
A

Assess dressing if it is intact and tight
Listen for breath sounds in both lungs. Compare good vs bad lungs.
Report anything <90% of pulse oximetry
Palpate chest tube site for subcutaneous emphysema, this could indicate poor tube placement
Record chest drainage every hour for 24 hours and then q8 hours
Notify physian if >200 ml in one hour and > 100 ml any hour after first hour. Change in color like yellow and bright red
Deep breathe cough and incentive spirometer
Infection should be monitored at insertion site so monitor wbc and fever
Dail chest x-ray for lung re expansion

23
Q

Where would you obtain chest drainage for wbcs? Drainage collection chamber or chest tube?

A

Chest tube. Because the tube is self sealing.

24
Q

Maintaining CDU

Level
Straight
Tape
Dye
Clamp
A

System must be below the chest. If too high, fluids or air will go back to pleural space. Gravity drainage is promoted.
Tubing should be straight and free of kinks and dependent loops.
Tape all systems, must be closed.
Monitor for water level in the system. Dye is done to make it easier to see.
Never clamp a chest tube without prescription. It could lead to tension pneumothorax.

25
Q

When is bubbling a problem?

Fluctuations upon respiration stops?

A

If there is continuous bubbling in the water seal chamber then there is air leak. First check connection sites before calling primary health provider. May order you to clamp to determine air leak. Dont clamp for too long and dont leve client when clamping is done

If tidaling stops it means the lung has re expanded or there is a kink or clot (in hemothorax) in tubing or a dependent loop is present.

26
Q

If tubing becomes disconnected?

If cdu falls over and leaks out or shifts to the drainage compartment?

If water is not present in water seal chamber?

A

Keep another sterile connector at bedside
Reconnect as fast as you can.

Re establish water seal.
Set cdu upright and check water levels. Fill water seal chamber to 2cm
Have client deep breathe or cough in case air went into pleaural space

Air can collapse the lung

27
Q

What if chest tube is accidentally pulled out?

In removing chest tube…

A

Occlusive sterile dressing is placed or taped down on 3 sides. If occlusive dressing is not present, cover with your hand and call someone to bring you one, otherwise every time they take a breath they will pull air into pleural space.

Have client valsalva or hummmmm and place occlusive dressing.

28
Q

Fractures of ribs and sternum

S/S

CRePS

A

Most common injuries in chest trauma, usually ribs 5 to 9 which are least protected by chest muscles.

Crepitus ( bones grating together )
Respiratory acidosis
Pain and tenderness
Shallow breathe

29
Q

Treatment for fractures of ribs and sternum

Complications
Incentive
Immobilizing chest
Non narcotic
Nerve block
Support area
A

Complications are observed such as hemo and pneumo thorax and flail chest

Incentive spirometry to preventrespirstory acidosis and pneumonia

Immobilizing chest is not recommended as it leads to shallow breathing and pneumonia

Non-narcotic analgesic just enough for client to cooperate

Nerve block to assist with productive cough

Support injured area with hands or pillow

30
Q

Flail chest

S/S

SAD PIC

A

Occurs with multiple fractures

SEE-SAW chest. Paradoxical chest wall movement. Chest sucks inwardly on inspiration and outwardly on expiration.
Anxious and shortness of breath
Dyspnea

Pain
Increased pulse
Cyanosis

31
Q

Treatment for flail chest

V SHIPP

A

Ventilate

Stabilize the area
Humidified oxygen
Intubate
Pain management
PEEP stabilizes the area and promotes lung expansion
32
Q

2 types of PEEP

A

Invasive and non-invasive

33
Q

Invasive PEEP

Ventilator
Alveoli open
Gas exchange
Expands
Classic for
A

Client is assisted with ventilator
At the end of expiration ventilator puts pressure on alveoli to keep it open
Improves gas exchange and decrease work of breathing
Expands and realigns ribs so they can start to grow back together
Used to treat classic ARDS, pulmonary edema and severe hypoxemia

34
Q

Non-invasive PEEP has 2 types

Apply

Used for

A

CPAP and BiPAP

Continuous positive airway pressure

Bilateral Positive airway pressure

Pressure to the lungs and improve oxygenation and ventilation

Both are used for sleep apnea, ards, copd and pulmonary edema

Clients may be moved to these devices when they are weaned from the ventilator

35
Q

CPAP

BiPAP

Priority assessment

A

Continuous pressure is delivered on expiration and inspiration. Used for obstructive sleep apnea and infants with underdeveloped lungs.

Pressure is applied on two different settings. One pressure on inhalation and a LOWER pressure upon expiration. Used on non-obstructive sleep apnea because it is tolerated better since they dont need to exhale against a high pressure

Anytime PEEP, CPAP BiPAP is used always assess for bilateral lung sounds every 2 hours. They could pop due to high pressure on lungs.

36
Q

Pulmonary Embolism

Causes

BOCH DV - these things make blood thick or promote stasis

A

A thrombus or blood clot, can also be air, fat or amniotic fluid in maternity client

Birth control pills
Obesity
Clotting disorders
Heart arrythmias like A-Fib

Dehydration
Venous stasis from prolonged immobility or surgery

37
Q

DVT
PE
VTE

A

Deep vein thrombosis is thrombosis in deep veins of the legs or arms

Pulmonary embolism is thrombosis that is broken off into lung artery

Venous thromboembolism that happens when you have both PE or DVT

38
Q

S/S of PE

HH PaPePu CCRAPS 
Hypoxemia
Hemoptysis
Partial oxygen
Petchiae
Pulse
Cyanosis
Chest pain
Restlessness
Atelectasis
HPN
SOB
A

Hypoxemia is number 1 sign. Death can occur within an hour of hypoxemia.
Hemoptysis or coughing up blood

PaO2 is low
Petechiae over Chest
Pulse increased

Cyanosis
Chest pain which is sharp and stabbing
Restlessness
Atelectasis on chest xray
Pulmonary HPN or cor pulmonale
Shortness of breath
39
Q

Patho of PE

Priority assessment

A

Blood clot leads to no gas exchange and backed up blood increases blood pressure in lungs that results in pulmonary HPN aka cor pulmonale this affects the Right ventricle leading to Right sided HF

Check CVP

40
Q

Diagnosis of PE

D-dimer
CTA
VQ scan
Angiography

A

D-dimer will be increased. This will tell clot anywhere in the body not just in the lungs

Computerized tomography angiogram is the most frequently used test to diagnose PE. Dye is used so check for renal function.

VQ scan is positive. This is done in radiology. Measures both airflow and blood flow to the lungs.

Pulmonary angiography is the most sensitive and specific test but is very expensive and invasive.

41
Q

Prevention of PE

Position
Stasis
Walk
Fluids
Compression
A

Change position every 2 hrs
Prevent stasis by flexing and extending feet, hips and knees every 2 to 4 hrs
Walking is needed 4 to 6 times a day
Hydrate by forcing fluids
Pneumatic compression devices will not be used if DVT is suspected because it can lead to PE

42
Q

Treatment for PE

Rest
Oxygen and pain
Anticoagulants
Precautions
Fibrinolytics
Surgery
A

Bed rest and affected leg may be elevated to promote blood flow and prevent stasis
Administer oxygen according to ABGs and Decrease pain
Administer anticoagulants. It has 3 types.
1.Vitamin K antagonists like warfarin
2.Thrombin inhibitors like heparin, enoxaparin(Lovenox) or dabigatran (pradaxa)
3. Factor Xa inhibitors like rivaroxaban(xarelto) or fondaparinux (arixtra)
These drugs prevent clot from getting bigger. Limit green leafy vegetables while on warfarin(coumadin)

Bleeding precautions
Fibrinolytic agents to help dissolve embolus
Pulmonary embolectomy is done when fibrinolytic is not used.
Inferior vena cava filtration device is used to prevent clots from going into pulmonary system

43
Q

Can a patient take warfarin and heparin at the same time?

A

Yes. Heparin is being tapered down while increasing warfarin.

Warfarin takes 48 to 72 hours to work and several more days to get to a therapeutic level
