Q

Oxygen toxicity

A

never without O2 from someone who needs it: administer and assess

37
Q

O2 toxicity

A

may occur with high PO2 levels usually for extended periods of time. The key is to administer oxygen as needed, maintain PO2 levels within normal limits
- assessment is key ecause of physiologic changes in the alveoli, the patient may experience cough and sore throat

38
Q

what physiologic changes occur as a result of O2 toxicity

A

decreased surfactant production, alveoli colapse, fibrosis

  • causes severe inflammatory response because of oxygen radicals and damages alveolar capillary membrane
  • lead to acute respiratory distress syndrome
39
Q

what are the other signs and symptoms related to O2 toxicity

A

pulmonary edema
hypoxemia
shunting of blood

40
Q

symptoms of o2 toxicity

A 
cough
sore throat
substernal chest pain
nausea vomiting
paresthesia- numbness
malaise- fatigue
- if allowed to continue O2 toxicity may eventually lead to endstage fibrosis. this decreases lung complicance and creates major respiratory problems
41
Q

prevention of 02 toxicity

A

use lowest effective concentration of oxygen

PEEP or CPAP prevent or reverse atelectasis and allow lower oxygen precetages to be used

42
Q

CO2 Narcosis

A
  • occurs in pt with extremely high CO2 levels

- what patients whould be at risk for CO2 narcosis- copd, drug over, dose, mederate sedation

43
Q

What is the main S/S associated with CO2 narcosis

A

decreased level of conciousness, lungs cant fix a problem in lung

44
Q

Decrease CO2 , increase H, and Decrease pH (decrease O2)

A

increased RR and TV
over time COPD patients
develop a tolerance to high CO2 levels

45
Q

Tracheostomies assessment and suctioning

A

suction when needed, listen to lungs and assessment

46
Q

Thracheostomies oxygenation

A

hyperoxygenate before and after suctioning

47
Q

Tracheostomies patient safety

A
  • no residue on cannula including excess liquid
  • hold onto faceplate when ties are removed (do not remove old ties until new ties are in place, dislodgement)
  • make sure the trach cannula is locked into place
  • get help if needed
  • do not cut the trach dressing- use precut dressing
  • cuff pressure- just enough (use minimum amount of air required to obtain airway seal think blood supply)
  • suction before deflating cuff- even nasosuction
  • during which part of respiration should the nurse deflate the cuff - expiration air and particles go out into mouth
48
Q

Tracheostomies emergency care

A

have another trach tube and obturator at bedside
do not manipulate immediately after surgery (usually 24 hrs)
comes out oxyenate and replace it

49
Q

suctioning

A

importance of assessment

  • based on need not routine
  • suctioning and trach are
50
Q

  • asepsis
  • do not suction on way down
51
Q

LPN

A

Stable patients only

  • assess the need for suctioning
  • suctioning
  • evaluate wheather status is improved after suctioning
  • trach care
  • not the first suction
52
Q

NAP

provide oral care
suction oropharynx (after being trained)
report need for suctioining to RN

53
Q

types of suctioning

A

oropharyngeal- mouth - clean
nasotracheal- nose - sterile
endotracheal- if patient is vented- sterile

54
Q

some patients may require a chest tube
position side laying or head down
head down is not to be used on patients with chest trauma or head injury

55
Q

incision into thoracic cavity may or may not involve lungs
- major surgery cuts into bone muscle cartilage mediam sternotomy and lateral thoractomies
median sternotomy open heart surgery
anterolateral thoracotomy front side
posterolateral thoractomy back side
- pain meds assess incision, splinting cough, chest tube care

56
Q

Lobectomies and resections

A

taking out portion of lung

  • 2 different chest tube 1 for air and 1 for fluid
  • lung expands some to facilitate
57
Q

Pneumonectomies

A

removal of entire lung

  • only time you will see a clamped tube
  • positioning is very important turned from back to operative side to prevent fluid from filling good lung
    • risk assessment and postoperative pulmonary toilet what time of history would predispose patients have more complications post op chest surgery smoking COPD asthema
58
Q

mediastinal

A

space that lies between the right and left thoracic cavities and contains large blood vessels heart mainstem bronchus and thymus gland. If fluid accumulates here the heart can become compressed and stop beating , causing death

fluid or air remval to re-expand lung

may be from trauma, pneumothorax, hemothorax, surgery

60
Q

insertion

A

patient prep

61
Q

Maintenance and nursing care

A

lung sounds- crackles, deminished lung sounds
drainage- amount color consistancy, decrease in amount in a few days
pain - so htey can cough and deep breath
deep breathing and resp status
CXR- reports , do daily
Subcutaneous emphysema- air under skin, should dissolve on their own

62
Q

Basic intervention

A

pulmonary toilet help chest to expand to help with removal

  • no milking or stripping increases pressure
  • check connection
  • 3 compartments
  • collection fluid drainage from pleural space collects - fluid drainage from pleural space collects here - amount color consistancy
  • water seal - acts as 1 way valve and creates a seal so that evaluated air connect re enter pleural space
  • check for continous bubbling (bad)
  • tidaling ball makes up and down (good)
  • suction
  • continous bubbling (good)
  • monitor suction control chamber it evaporates (keep at 20)
