Chest Tubes & Pulmonary Disorders Flashcards
Describe Kussmaul’s Breathing.
Air hunger - marked by increase in depth and rate of breathing.
Define Cheyne-Stokes breathing.
Periodic breathing characterized by rhythmic waxing and waning of the depth of respirations.
Define Rhonchi
Rhonchi - Low-pitched, coarse, loud, moaning/snoring sounds heard primarily on expiration, that arise from the large airways (i.e., trachea or bronchi).
What is the implication of a chest drainage tube that is clamped, kinked or has pressure applied to it?
Kinking, looping or pressure on the drainage tubing can produce back pressure, which may force fluid back into the pleural space or impede its drainage.
Fluctuation of the water level in the water seal chamber (aka tidaling) is normal during respiration (rises with inspiration and returns to Norma upon expiration), in which situations does tidaling stop?
1) When the lung has re-expanded
2) When the tubing is obstructed (by clots, fibrin or a kink)
3) When a loop of tubing hangs below the rest of the tubing
4) When motor or wall suction is not working properly.
Distinguish between the 3 following types of Pneumothoraxes:
1) Simple Pneumothorax
2) Traumatic Pneumothorax
3) Tension Pneumothorax
1) Simple Pneumothorax - When air enters the pleural space via a ruptured bleb or a bronchpleural fistula.
2) Traumatic Pneumothorax - When air enters the pleural space via chest wall wound or a laceration in the lung itself (air escapes from the the lungs and into the pleural space with each breath).
3) Tension Pneumothorax - When air enters the pleural space but cannot escape, causing tension on the lungs and collapsing it. This also causes the great vessels and the trachea to shift toward the unaffected side of the chest (mediastinal shift) .
Describe Subcutaneous Emphysema.
This is when air escapes into the tissue under skin takes on a misshapen, swelling and puffy appearance. It produces a crackling sound upon Palpation. It is usually self limiting as the air is absorbed spontaneously over time.
When is it ok to clamp the drainage tubing momentarily? What does clamping the tube put the patient at risk for?
1) When checking for air leaks
2) When changing the draining apparatus
* Clamping puts the patient at risk for a Tension Pneumothorax
Differentiate between the 3 following terms:
1) Hemothorax
2) Hydrothorax
3) Empyema
4) Fibrothorax
1) Hemothorax - Blood in the pleural space
2) Hydrothorax - Water in the pleural space
3) Empyema - Pus in the pleural space
4) Fibrothorax - Fibrosis of the pleural space surrounding the lung
What size tube is used and where is it placed (anatomically) in order to remove the following from the pleural space:
1) Air
2) Fluid
1) Air - 28 to 32 French chest tube place anteriorly in the 2nd intercostal space.
2) Fluid - 32 to 40 French chest tube placed mid-axillarily between the 7th and 8th intercostal space
Define Fremitus
Fremitus is a vocal vibration detected on palpation, it is often presenting patients with pneumonia.
What is the difference between Hypoxia and Hypoxemia?
1) Hypoxia - Deceesed oxygen supply to the tissues.
2) Hypoxemia - Dcrease of oxygen content in arterial blood.
What is the FiO2 available delivered to the patient at the following rates:
1) Room Air
2) 1L/min
3) 2L/min
4) 3L/min
5) 4L/min
6) 6L/min
1) Room Air - 21%
2) 1L/min - 24%
3) 2L/min - 28%
4) 3L/min - 32%
5) 4L/min - 36%
6) 5L/min - 40%
* Each additional liter of oxygen flow is approximately and addition of 4% FiO2.
What are the 5 mentioned complications of Severe Acute Asthma?
1) Rib fractures
2) Pneumothorax
3) Pneumomediastimun
4) Atelectasis
5) Pneumonia
What is Pulsus Paradoxus?
Pulsus Paradoxus (a sign of Asthma) is an abnormally large decrease in systolic BP and pulse wave amplitude during inspiration.
