Respiratory Flashcards
Chest tube insertion
What has happened that the client needs a chest tube? Lung has collapsed.
If the chest tube is placed in the upper anterior chest, (2nd intercostal space) then it is for removal of air.
If the chest tube is placed laterally in the lower chest, (8th or 9th intercostal space) then it is for drainage.
Can the client have both? Yes
They are y-connected together and attached to a closed chest drainage unit
(CDU).
The chest tube is 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.
What is the purpose of the CDU?
It is to restore the normal vacuum pressure in the pleural space. The CDU does this by removing all air and fluid in a closed one-way system until the problem is corrected.
Thoracentesis
a. Pre-procedure:
• X-RAY and baseline vitals
• Positioning:
Sitting up leaning over the bedside table.
Sit in a chair backwards, propped up over the back of the chair. Can’t sit up? Lie on unaffected side with HOB at 45o.
b. Procedure:
• Client must be very still, no coughing or deep breaths.
• The fluid is being removed from the pleural space.
• As the fluid is removed the lung should reexpand.
• Since you are removing fluid, the client could go into a fluid volume deficit.
• Therefore, you should be checking the vitals.
c. Post-procedure:
• Another X-ray.
Chest tube chambers
1) Drainage collection chamber:
• The chest tube connects to a 6 foot connection tube that leads to the drainage collection chamber.
• What if this chamber fills up? Tension pneumothorax. Get a new one before full.
2) Water seal chamber:
• What is the purpose of the water seal?
To promote one way flow out of the pleural space which will prevent air from moving back up the system and into the chest.
• The drainage chamber and water seal chamber are connected by a straw- like channel that allows the drainage to remain in the first chamber and the air to go down into the water of the water seal chamber.
This chamber contains 2 cm of water which acts as a one-way valve. In other words we are preventing backflow.
• You may see bubbling when client coughs, sneezes, or exhales.
• You will see a slight rise and fall of water in the water seal tube as the
client breathes.
This fluctuation is called tidaling and is normal. If tidaling stops it usually means that the lung has re-expanded.
• Any air exits the water seal chamber and 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.
3) Suction Control Chamber:
• If the client needs suction to remove air and fluid, this chamber controls the amount of pressure applied.
• Sterile water is placed in this chamber up to the 20 cm line. This is the usual prescribed amount.
• Turn on the wall vacuum suction until you have slow gentle continuous bubbling.
***If a dry suction system is used, water is not used to regulate the pressure, therefore no bubbling. A dial is used to set the desired negative pressure. Once again increasing the vacuum wall suction will not increase the pressure.
Assessment of chest tube
• Assess dressing
It must be kept tight and intact. Reinforce if needed
• Listen to lung sounds bilaterally.
• Monitor pulse oximetry and report anything < 90.
• Record drainage every hour for 24 hours and then every 8 hours .
• Notify physician of 100 mL of drainage or greater in 1st hour, and if there is a change in color to bright red.
• Deep breathe, cough, and use incentive spirometer.
• Watch for fever, ↑WBCs, and drainage because they could develop an infection at insertion site.
• Watch daily chest x-rays for reexpansion.
Maintaining chest tube.
Keep below level of chest
If you lift it to high→fluid will go back in.
Want gravity drainage.
Keep tubing straight and free of kinks and dependent loops.
Tape connections, it must be a closed system.
Monitor the water levels in the system.
Want to see tidaling (fluctuations)with respirations
Fluctuations will stop when the lung has re-expanded, or if there is a kink/clot in tubing, or a dependent loop present in the system.
a. What do you do if the tubing becomes disconnected?
1) Another sterile connector at bedside.
2) Reconnect as fast as you can.
b. What if my CDU falls over and my water leaks out or shifts to the drainage compartment?
Do whatever you can to reestablish the water seal.
Set CDU upright, and fill water seal chamber to 2 cm of water.
If there is not water in the water seal chamber then air can do what? Collapse the lung.
• What if the chest tube is accidentally pulled out?
Sterile vaseline gauze taped down on 3 sides
c. When is bubbling normal?
Chest tube connected 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.
d. When is 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.
Chest tube removal
• Have client take a deep breath and hold (Valsalva) and place Vaseline gauze over the site.
Chest trauma
Hemo/pneumothorax
a. Pathophysiology:
• Blood or air has accumulated in the pleural space.
• What has happened to the lung? Collapsed
b. S/S:
• SOB
• Increased HR
• Diminished breath sounds on the affected side.
• Less movement on the affected side.
• Chest pain
• Cough
• What will show up on the chest x-ray? Air or blood
• Subcutaneous emphysema is air trapped in the tissue (usually neck and face).
c. Tx:
• Thoracentesis, chest tubes, daily CXR
• 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
Tension pneumothorax
• Trauma, PEEP, clamping a chest tube, or taping an open pneumothorax on all 4 sides without an air valve can cause a tension pneumothorax.
a. Pathophysiology:
• pressure has built up in the chest/pleural space and has collapsed the lung→pressure pushes everything to the opposite side (mediastinal shift).
b. S/S:
• Subcutaneous emphysema, absence of breath sounds on one side, asymmetry of thorax, respiratory distress.
• Can be fatal as accumulating pressure compresses vessels→ decreases venous return→ decreases CO.
c. Tx:
• Large bore needle is placed into the 2nd ICS (by the physician) to allow excess air to escape, find the cause, chest tube.
Open pneumothorax
Sucking wound
a. Pathophysiology:
• Opening through chest that allows air into the pleural space.
b. Tx:
• Have the client inhale and hold or Valsalva (take a deep breath and hold) or hummmmm.
Both of these will 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 how many sides? 3
Fourth side acts like an air vent
• Have client sit up if possible to expand lungs.
Trauma clients stay flat, until evaluated for other injuries.
Fractures of the ribs and sternum
• Most common injuries from chest trauma.
a. S/S:
• Pain & tenderness
• Crepitus (bones grating together)
• Shallow respirations>resp acidosis
b. Tx:
• Non-narcotic analgesic so they can breath
• Nerve block to assist with productive coughing.
• Support injured area with hands.
• Not recommended to immobilize with chest binders and straps, this could lead to pneumothorax and flail chest.
Flail chest
Multiple rib fractures a. S/S: • Pain • Paradoxical chest wall movement (see-saw chest); chest sucks inwardly on inspiration and puffs out on expiration. To assess chest symmetry always stand at foot of bed to observe how the chest is rising and falling. • Dyspnea, cyanosis • Increased pulse
b. Tx:
• Stabilize the area, intubate, ventilate.
• Positive pressure ventilation stabilizes the area.
1) PEEP: Positive End Expiratory Pressure
• On end expiration the vent exerts a pressure down into the
lungs to keep the alveoli open.
• Improves gas exchange and decreases the work of breathing.
• It expands and realigns the ribs so they can start growing back together.
• PEEP may also be used to treat pulmonary edema or severe hypoxemia.
• The classic reason to use PEEP is Adult Respiratory Distress Syndrome (ARDS).
2) BiPAP: Bi-level Positive Airway Pressure
• Used a lot with COPD, heart failure, and sleep apnea.
• Exerts different levels of pressure on inspiration and expiration.
3) CPAP: Continuous Positive Airway Pressure
• Constant pressure is used for inspiration and expiration.
• Used for obstructive sleep apnea.
• Anytime you see PEEP, CPAP, or Bi-PAP, your priority nursing assessment is to check bilateral lung sounds q2 hrs.
Pulmonary embolism
S/S
- Cause:
• This can occur if a client becomes dehydrated, has venous stasis from prolonged immobility or surgery, or has been taking birth control pills.
• Clotting disorders or heart arrhythmias like A-Fib. - S/S
• Hypoxemia #1
• PO2? Decreased
• Short of breath, cough, ↑RR
• Increased D-dimer (increased with pulmonary embolus)
Will tell if a clot is located anywhere in the body (not just in the lungs). Shows up in post op Pts
• Positive VQ scan (a ventilation/perfusion scan that can detect an embolus; done in radiology)
Looks at blood flow to the lungs, dye is used, remove jewelry from chest area so that it will not give false results.
• A positive spiral CT or CT angiography
• Hemoptysis coughing blood
• Pulse increases
• Chest pain (sharp, stabbing)
• CXR will show atelectasis
• BP in lungs increases. pulmonary hypertension
Pulmonary embolism treatment
Prevent! Ambulate and hydrate. Oxygen ABGs Ventilator Decrease pain Heparin sodium, Warfarin (Coumadin®), Enoxaparin (Lovenox®)
