Q

Thoracentesis procedure

A

Client must be very still, no coughing or deep breaths
The fluid/blood/exudate is being removed from pleural space
As the fluid is removed, the lung should reexpand
Since you’re removing fluid, the client could go into a fluid volume deficit, so check vitals

Q

How is the chest tube secured to the client?

A

Sutured to the chest wall and a Vaseline or air tight dressing is applied around the chest tube exit site. The chest tube is then connected to a closed chest drainage unit

Q

What is the purpose of the CDU?

A

Q

Tidaling

A

Fluctuation of rise and fall of water in the water seal tube as the client breathes. Normal, if it stops, it usually means the lung has reexpanded, there is a kink/clot in tubing, or a dependent loop is present

Q

What happens when air exits the water seal chamber?

A

It enters the third chamber called the suction control chamber. This allows any air to be vented out through the air vent found at the top of the suction control chamber

Q

Dry suction system

A

Water is not used to regulate the pressure and therefore has no bubbling. A dial is used to set the desired negative pressure. Increasing the vacuum wall suction will not increase the pressure.

Q

What level should the CDU be at?

A

Below level of chest

25
Connections of CDU
Tape them, it must be a closed system
26
What do you do if the CDU tubing becomes d/c
Keep another sterile connector at bedside, reconnect as fast as you can
27
What do you do if the CDU falls over and the water leaks out or shifts to the drainage compartment?
Do whatever you can to reestablish the water seal. Set the CDU upright, check all the chambers, and fill the water seal chamber to 2cm of water Have client deep breathe and cough in case any air went into pleural space If there is not water in the water seal chamber then air can collapse the lung
28
What if the chest tube is accidentally pulled out?
Sterile vaseline gauze taped down on 3 sides. Otherwise, every time they take a breath, they will pull air into pleural space
29
When is chest tube bubbling normal?
Chest tube connection to suction, gentle continuous bubbling is expected in the suction chamber If a client with a pneumothorax is coughing, sneezing, or just taking a deep breath and exhaling, you may see intermittent bubbling in the water seal chamber As long as there is intermittent bubbling, the client needs the chest tube bc air is still leaking out of the pleural space
30
When is chest tube bubbling a problem?
If there is continuous bubbling in the water seal chamber, then you have an air leak in the system Never clamp a chest tube without an order. It could lead to a tension pneumothorax
31
Chest tube removal
Have client take a deep breath and hold (valsalva) and place an occlusive petroleum dressing over the site
32
Patho of hemo/pneumothorax
Blood or air has accumulated in the pleural space | The lung has collapsed
33
S/S of hemo/pneumothorax
``` SOB Increased HR Diminished breath sounds on affected side Less movement on affected side Chest pain Cough Blood or air on CXR Subq emphysema is air trapped in tissue (usually face, neck, chest) ```
34
Never do what to a penetrating object?
Pull it out
35
Tx of hemo/pneumothorax
Thoracentesis, chest tubes, daily CXR
36
If a pneumothorax is present and the client has a chest tube, what type of bubbling would be expected in the water seal chamber?
Intermittent bubbling
37
Patho of tension pneumothorax
Pressure has built up in the chest/pleural space and has collapsed the lung. Pressure pushes everything to the opposite side. (mediastinal shift)
38
What can cause a tension pneumothorax?
Trauma, PEEP, clamping chest tube, taping an open pneumothorax on all four sides without an air valve
39
S/S of tension pneumothorax
Subq emphysema, absence of breath sounds on one side, asymmetry of thorax, respiratory distress Can be fatal as accumulating pressure compresses vessels and decreases venous return which decreases CO
40
Tx of tension pneumothorax
Large bore needle is placed into the 2nd intercostal space by doc to allow excess air to escape. Then the cause is found, and the chest tubes are inserted
41
Open pneumothorax
"Sucking wound" | Opening through chest allows air into pleural space
42
Tx of open pneumothorax
Have client inhale and hold or valsalva or hummmmm to increase the intra-thoracic pressure so no more outside air can get into the body Then, place a piece of petroleum gauze over the area. Tape down 3 sides, 4th side acts as air vent/flutter valve Have client sit up if possible to expand lungs Trauma clients stay flat until evaluated for other injuries
43
S/S of ribs and sternum
Pain/tenderness Crepitus (bones grating together) Shallow respirations Respiratory acidosis
44
Tx of fx ribs/sternum
Non-narcotic analgesic Nerve block to assist w/ productive coughing Support injured are with hands Not recommended to immobilize with chest binder and straps bc it could lead to shallow breathing, atelectasis and pneumonia Observe for complication such as pneumothorax, hemothorax, and flail chest
45
Multiple rib fx
Flail chest
46
S/S of flail chest
``` Pain Paradoxical chest movement To assess chest symmetry, always stand at food of bed to observe how the chest is rising and falling Dyspnea, cyanosis Increased pulse ```
47
Paradoxical chest movement
"See-saw chest" | Chest sucks inwardly on inspiration and puffs out on expiration
48
Tx of flail chest
Stabilize area, intubate, ventilate | PEEP
49
PEEP
Client is on vent On end expiration, the vent exerts pressure down into the lungs to keep alveoli open Improves gas exchange and decreases the work of breathing Expands and realigns ribs so they can start growing back together
50
PEEP can treat what?
Flail chest, pulmonary edema, sever hypoxemia, ARDS
51
BiPAP
Bi-level Positive Airway Pressure Used for ARDS in clients with COPD, heart failure, sleep apnea Exerts different levels of positive pressure support, along with oxygen
52
CPAP
Continuous Positive Airway Pressure | Pressure is delivered continuously during spontaneous breathing, for both inspiration and expiration
53
What is CPAP used for?
Obstructive sleep apnea
54
What is the priority nu assessment with PEEP, CPAP, or Bi-PAP?
Bilateral breath sounds
55
Causes of pulmonary embolism
If a client becomes dehydrated, has venous stasis from prolonged immobility or sx, birth control pills, clotting disorders or heart arrhythmias like A-Fib (All these things make blood thick. Clot forms, travels to lungs. Usually comes from legs)
56
S/S of PE
``` #1: hypoxemia Decreased PaO2, give 100% O2 SOB, cough, increased RR Increased D-dimer, tells if there is a clot located anywhere in the body, not just lungs Positive VQ scan: most widely used test (ventilation/perfusion scan used to detect an embolus, done in radiology. Looks at blood flow to lungs. Dye is used, remove jewelry from chest area) Positive spiral CT or CT angiography Hemoptysis (coughing up blood) Increase pulse bc hypoxic Chest pain: sharp, stabbing CXR shows atelectasis increased BP in lungs-pulmonary HTN ```
57
Tx of PE
Prevent with ambulation and hydration, SCDs, isometric exercises to decrease stasis Oxygen ABGs Decrease pain Heparin sodium, warfarin, enoxaparin Bleeding precautions Sx Bedrest Elevate extremities to increase venous blood return, decrease pooling TED hose to increase venous return and decrease pooling: often used with SCDs, with a known clot: use TEDs or SCDs on the unaffected extremity or not at all Warm, moist heat to decrease inflammation
58
Normal aPTT
30-40 seconds
59
Normal PT
11-12.5 seconds
60
Therapeutic INR
2-3
61
Can you be on heparin and warfarin at the same time?
Yes
62
Why don't you put cold on a vein with PE
Excessive vasoconstriction
63
Why don't you put hot on a vein with PE
Excessive vasodilation
64
How often do you remove TED hose?
Twice a day/once per shift
