25
venturi mask
most reliable and accurate method of delivering precise concentrations of O2 - deliver precise high flow rates of O2 - dial settings on a flow adaptor setting should match wall O2 can be humidified
26
Aerosol masks
face mask with corified tubing provides a lot of humidification some have condisation bag
27
Trach collars
not as accurate O2 delivery attaches to neck with strap delivers O2 via tracheastomy - does not attach snuggly
28
T- pieces
connects to trach very accurate O2 delvery allow an inline catheter (Ballard catheter) to be connected for suctioning - tight fit allows for better O2 and humidity delivery - empty as necessary
29
Oral airways | artifical airways
indications for patient that is breathing spontaneously keep tongue clear of airway trauma or seziure post up need to be unconcious - measure from jaw to back angle below ear - airway should reach from oepning of mouth to the back angle of the jaw - tip of the nose to the earlobe
30
insertion
patient on back with neck hyper extended insert with curved tip pointing up to roof of mouth rotate 180 degrees as it passes uvula - do not tape
31
nasal airway
``` nasopharynegeal airway (nasal trumpet) inserted through nare and protrudes into back of pharynx - can bypass nasal nucosa great for NG suctioning ```
32
BiPAP, CPAP, PEEP
- all involve positive pressure helps move air down to the treachea - all are aimed at keeping the airways open - side effects of positive pressure - decreased venous return and blood pressure due to increased pressure - edema so such pressure pushes fluid out of cells - subcutaneous emphysema - barotraumas-when you blow out a lung
33
BiPAP
Bilevel positive airway pressure - pressure set for inspiration and expiration - higher during inspiration and lower with expiration - nasal or mask - keep air tight seal - CO2 retentation these work great
34
CPAP (continuous positive airway pressure)
- continuous pressure - pressure delivered continusouly during spontaneous breathing nasal or mask or via mechanical ventilation keep air tight seal - sleep apnea
35
PEEP (positive end expiratory pressure)
end expiratory pressure usually via mechanical ventiation especially useful in treatment of patients with ARDs
36
Oxygen toxicity
never without O2 from someone who needs it: administer and assess
37
O2 toxicity
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
what physiologic changes occur as a result of O2 toxicity
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
what are the other signs and symptoms related to O2 toxicity
pulmonary edema hypoxemia shunting of blood
40
symptoms of o2 toxicity
``` 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
prevention of 02 toxicity
use lowest effective concentration of oxygen | PEEP or CPAP prevent or reverse atelectasis and allow lower oxygen precetages to be used
42
CO2 Narcosis
- occurs in pt with extremely high CO2 levels | - what patients whould be at risk for CO2 narcosis- copd, drug over, dose, mederate sedation
43
What is the main S/S associated with CO2 narcosis
decreased level of conciousness, lungs cant fix a problem in lung
44
Decrease CO2 , increase H, and Decrease pH (decrease O2)
increased RR and TV over time COPD patients develop a tolerance to high CO2 levels
45
Tracheostomies assessment and suctioning
suction when needed, listen to lungs and assessment
46
Thracheostomies oxygenation
hyperoxygenate before and after suctioning
47
Tracheostomies patient safety
- 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
Tracheostomies emergency care
have another trach tube and obturator at bedside do not manipulate immediately after surgery (usually 24 hrs) comes out oxyenate and replace it
49
suctioning
importance of assessment - based on need not routine - suctioning and trach are
50
patient safety principles
delegation issues - stable predictable, patients LPNs can suction - asepsis - do not suction on way down
51
LPN
Stable patients only - assess the need for suctioning - suctioning - evaluate wheather status is improved after suctioning - trach care - not the first suction
52
NAP
provide oral care suction oropharynx (after being trained) report need for suctioining to RN
53
types of suctioning
oropharyngeal- mouth - clean nasotracheal- nose - sterile endotracheal- if patient is vented- sterile
54
chest surgeries
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
Thorocotomies
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
Lobectomies and resections
taking out portion of lung - 2 different chest tube 1 for air and 1 for fluid - lung expands some to facilitate
57
Pneumonectomies
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
mediastinal
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
59
Indication
fluid or air remval to re-expand lung | may be from trauma, pneumothorax, hemothorax, surgery
60
insertion
patient prep adequate exposure Local anesthetic
61
Maintenance and nursing care
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
Basic intervention
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)
63
specimen collection
small gage needle into tubing self healing tubing
64
facilitate drainage
no dependent loops below chest level fluid levels and suction no clamping kinks in tubing
65
Suction verses water seal
water seal no suction gravity
66
ambulation and transfer
place to water seal maintain integrity of system positioning
67
Dressing care
occlusive airtight vaseline based if not occlusive air leaks can occur - reinforced as needed - asepsis - suture care
68
equipment troubleshooting
bubbling in the H2O seal compartment continous bubbling leak
69
no tidaling
tube may be blocked
70
sudden decrease in drainage
king or clog
71
Emergency care
unit spills over- change divice disconnected- from patient put in saline and create water seal removed from patient occulsiive dressing (vaseline) on 3 sides
72
MDI
small hand held pressurized device deliver measured dose of drug with activation - dosing usually 1-2 puffs Shake inhaler breath out all the way - hold inhaler or spacer chamber in mouth, slowly breathe in through mouth and press inhaler one time, breathe slowly and deeply in
73
DPI
``` dry powedered medication that is breath activated aerosol created during inhalation no propellent is used less manual dexterity than MDI no needed to to coordiante puffs with inhalation quick deep breath for 10 seconds no spacer counter avoid humidity may club ```
74
Nebulizer
delivers a suspension of pine particles of liquid in gas take medication in an aerosle form by O2 or compressed air sit upright breath slowly and deep diapgramtic breathing clean
75
mucolytics
break down mucus change characteristics of mucus , increase or liquefy respiratory secretions and aid in clearing of airways (mucomist should be given with a bronchodialter)
76
expectorants
increase cough reflex increase productive cough to clear airways enhances the output of respiratory tract fluids by reducing the adhesiveness and surfance tension of these fluids allowing easier movement of the less vicous secretions - humabid
77
Bronchodilators
let air in - b2 adrenergic agonists, anticholinergic agents methylaxtines - stimulate sympathetic nervous system to cause bronchodilation - short and long acting
78
short acting
used to relieve acute bronchospams "rescue" medication onset with mins and last for 4-8 hrs cause bronchodilation and increase mucociliary clearance - albuterol - short term more than 4 x a week build up tolerance
79
long acting
usinig with inhaledcorticcosteriods for long term control of asthma used only once ever 12 hrs , they are affective for 12 hrs not to be used for quick relief of bronchospasm ex- salmeterold, formoterol
80
combination therapy
inhaled corticosteriod and a long acting b2 adregneric agent ex advair and symbicort
81
anticholinergic
work on parasympathetic system to block bronchoconstriction - cause broncodilation - slower onset peak 30 min duration 4-6 hrs
82
theohyllines (methlxanthines)
PO or IV bronchodilator with mild anti inflammatory effects montior serum blood levels for toxicity narrow margin of saftey therapeutic levles 10-20 (drs usually give 5-10)
83
antihistamines
allergic reactions -hyperactivity of airway block the release or action of histamine that increases secretions and narrows airways allergra claritin zyrtec benadryl
84
corticosteroids
PO IV and MDI/DPI forms anti inflammatory med reduce bronchial hyperresponsiveness - example prednisone, pulmocort, flovent increase blood sugar increase risk of infection may take 2 weeks taper dose
85
leukotrine modifers
block action of leuktrines (potent bronchoconstrictors can cause airway edema and inflammation) singulair maitience not very good alone mointor liver fuction - can affect comodin warfirin
86
tb therapy
compliance huge issue 6-9 month therapy - isoniazid- can cause peripheral neourpathy, can react ith teptiromy, GI upset - rifampin- red discoloration of body fluids an drecrease effectiveness of birth control - metabolized in liver no drinking monitor liver enzymes
