56
New cards

BNP

= brain natiritic peptide

  • hormone released from the heart when under stress in respinse to increased venticlar pressue and volume

  • high BNP = heart failure with pulomary edema (but NOT with ARDS)

57
New cards

medical management of ARDS

  • Intubation, mechanical ventilation with Positive End Expiratory Pressure (PEEP) to keep alveoli open (normally alveoli deflate with breathing out, this keeps them open during expiration to increase gas exchange ie: o2 in and Co2 out)

  • Treat hypovolemia to keep hemodynamically stable

  • Turn patient to Prone position

    • is best for oxygenation,

    • the weight of the heart, abdominal organs, and diaphragm is shifted away from the lungs,

    • allowing for better ventilation of the dorsal (back) lung regions that have collapsed d/t atelectasis.

    • Also Increases end-expiratory lung volume

    • Improves bronchial draining

    • Improves functional residual capacity

    • Improves gas exchange

    • Opens collapsed alveoli

  • frequent repositioning to safeguard integumentary system. Improves oxygenation

  • CPAP: pushes O2 in using single continuous pressure

    • improves oxygenation (does not remove co2)

    • used for sleeo apnea

  • BIPAP: helps move air in and out

    • high pressure on inhalation, lower pressure on exhaltion

    • helps remove CO2

    • used for COPD

60
New cards

  • PaCO2 >50 MM HG  (norm values 35-45 mmHg)

  • Vital capacity <10ml/kg  (norm 50 ml/kg)   

    • (reduced vital capacity= weakness of respiratory and diaphragm muscles to have enough force to draw air in and out of lungs)

  • Negative inspiratory force (NIF) < - 25 cm H2O (norm NIF is - 60 to  -100 cm H20)

    • The NIF= measures the strength of respiratory muscles and diaphragm, by quantifying the maximum negative pressure generated during inhalation effort

    • FEV <10ml/KG ( Forced Expiratory Volume)

sarcoidosis - pleural involvement

  • Sarcoidosis is an immune disorder meaning the immune system is dysfunctional and forms granulomas.

  • What is a granuloma?

    • A granuloma is a small clump of immune cells that forms when the body tries to wall off something it sees as foreign but can’t get rid of.  Granulomas are made up of macrophages and other immune cells.

    • Think of it as the body building a fence around a problem

• Sarcoidosis is an interstitial lung disease that is inflammatory multisystem, granulomatous

79
New cards

why are granulomas a problem?

take up space in the lungs, make lung tissue stiff, restricting lung expansion and impair gas exchange

  • cause: unknown

  • occurs between ages of 20-40

80

  • positioning

    • elecate HOB 30-45 desgrees

    • change position from back to side frequently

  • self care

    • arm and shoulder exercises

    • pain relief pedalities

    • acticity - rest balce

    • avoid bronchial irritats

    • follow up care

    • smoke cessation

nursing care wth chest tube

•Pain Control**

•Narcotics/ Local for tube placement 

•NSAIDS for tube duration

•Anxiety treatments prn

•Nurses are responsible for keeping tubing connections patent and ensuring they are not compressed or kinked - position your patient well

•Ensure the drainage system is always below the level of the client’s chest to use gravity to drain air and fluid from the pleural space.

•Monitor the levels of fluid in water seal and suction control chambers – sterile water may need to be added prn

•Vital signs, pulmonary assessment, insertion site evaluation

•Daily x-rays

•Q Shift (or sooner) measurements of drainage

•Document the quality of drainage – sanguineous, serosanguinous, yellow, clear or opaque

  • encourage IS and ROM with arms

chest tube complications

  • bubbling in water seal chamber of chest tube system —> indicates air leak

  • subQ emphysema or crepitis —> leakage of air into the sub Q tissue

89
New cards

chest tube emergency care

  • if drainage system spills over —> encoruage p to take a few deep breaths with forceful exhalations and coughs

  • sett up a new system and change pt over

  • should the drainage system break, submerg the distal end of tubing into a bottle of sterile water (kept at bedside)

complications of chest tubes

infection at insertion site

PNA from poor pulmonary toilet

frozen shoulder

systemic hypotesion with rapid high volume drainage

91
New cards

chest tube removal

  • Suction usually discontinued, patient on water seal for 6-24 hours prior to removal

  • Chest x-ray prior

  • Lungs re-expanded; pleural drainage ceased

  • Pre-medicate*

  • Pre-educate about upcoming events

  • Sutures holding tube in place are cut, as patient exhales a deep breath the tube is   removed.

  • Occlusive dressing placed over the wound

  • Pleura self-seals usually – wound heals in several days – offer NSAIDS prn

92
New cards

blunt chest trauma

•involves forceful impact from dull objects (like car crashes, falls) causing compression/shearing, leading to bruises, fractures, internal damage without skin break

93
New cards

penetrating chest trauma

pierces the skin with sharp objects (knives, bullets) creating open wounds, causing direct tissue damage, infection risk, and potential organ perforation, with mechanisms differing in energy transfer and injury pattern.

94
New cards

pulmonary contusion and rib fractires

•Contusion causes alveolar hemorrhage/edema; rib fractures cause pain and hypoventilation leading to atelectasis.

•Manage with pain control, pulmonary hygiene, and respiratory support as needed.

95
New cards

Flail Chest

  • multiple contiguous rib fractures causeing paradoxical chest wall motion - creating a loose, disconnected piece of bone that moves opposite way you breathe

  • ribs are floating

    • paradoxical movement - making it hard to breathe

    • inhale = chest moves out

    • exhale = chest moves in

  • high risk for resp failure

open pneumothorax

penetrating thoracic injury that causes air to enter from the outside in

<p>penetrating thoracic injury that causes air to enter from the outside in </p>
97
New cards

closed pneumothorax

air enters the pleura space without an outside wound

causes:

  • traumatic impact (MVA) or

  • spontaneous rupture of lung tissue

    • primary spontaneous: without history of lung diease

    • secondary: with history of lung disease

tension pneumothorax

complication of open and closed

  • worsening pneumothorax where air connot escape

  • increaing intrathoracic pressure

  • pressure starts to displace heart, good lung, and trachea

    • —> tracheal deviation*

  • emergceny situation

99
New cards

diagnosis & CXR findings

  • absent lung parkings, visceral pleural line of CXR, ultrasounds shows “lung point” (location of chest wall)

  • ct more sensitive for small pneumothorax

  • ABG

    • decrease in PaO2

    • increase in PaCO2
