IGGY: Respiratory & Oxygen Flashcards
Alveoli to blood = (Gas exchange/ Perfusion)
Delivery of oxygen to tissue = (Gas exchange/ Perfusion)
Alveoli to blood = Gas exchange
Delivery of oxygen to tissue = Perfusion
Pharynx or (throat) is divided into these 3 areas
Starting at the top
Naso
Oro
Laryngopharynx
Where does gas exchange take place
Between alveoli and Lung capillaries
NOT AIRWAYS
Which side of the heart recieves oxygen poor blood
Which side pumps oxygen rich blood to the body?
Which side pumps oxygen poor blood to the lungs
Poor = Right
Rich = Left
Pumps to lungs = Right
Hemoptysis is most often seen in…
Chronic bronchitis
Lung cancer
Tracheal shift
Pneumothorax, Pleural effusion, medistinal mass, neck tumor PUSH TRACHEA WHICH SIDE
Pneumonectomy, fibrosis, Atelectasis PUSH TO WHICH SIDE
Pneumothorax, Pleural effusion, medistinal mass, neck Tumor = AWAY Affected Area
Pneumonectomy, fibrosis, Atelectasis = Towards affected area
AP Diameter:
Normal
Abnormal
Reason why Abnormal
1:1.5
1:1
Emphysema/ COPD (Barrel chest)
Crepitus (air under skin) is felt as….
Crackling
Pneumothorax
Tactile fremitus (vibration) is a normal find
Reduced fremitus is associated with…
Pneumothorax/ pleural effusion
Air / Fluid trapped in the space
Percuss the lungs
What is a normal lung sound
Resonance
Abnormal breath sounds are called
Adventitious
Breath sound heard over trachea/ larynx
Bronchial
Normal breath sound heard over Major Bronchi
Bronchovescular
Normal breath sound heard over peripheral field of lungs- air flows from smaller bronchioles to alveoli
Vesicular
Nurse role in patients with a CT scan
Sensitivity to contrast material
Allergy to Iodine & Shellfish
IV contrast materials is nephrotoxic
Kidney function
Type II diabetes?
Taking Metformin
Fever & heavy exercise will have this affect on acid/Base balance
Acidosis
Increased CO²
Benzocaine topical anesthetic can cause this serious reaction
Methemoglobinemia (Cyanosis & Chocolate Brown blood)
Call rapid
Assess how often after endoscopic test
15 min for first 2 hrs
Prescription needed for ___ L or more of oxygen
4L/ min
Type of oxygen delivery mask used for hypercapnia
Venture
Humiditfy oxygen at this level
4L/min
Nasal Cannula, simple face mask, partial rebreather, and non-rebreather
This type of oxygen delivery system
Low-Flow
Requires patient to breath in room air also
Nasal Cannula provides these many liters of oxygen
1 L 24% - 6 L 44%
Simple face mask oxygen amount delivered
5L 40% - 8L 60%
Non-rebreather mask
Valves should be (closed / open) during Inhalation & (closed / open) during exhaling
Caution:
Closed = Inhalation
Open = exhaling
Suffocation can occur with kinks in the bag/ oxygen source disconnects
Partial rebreather mask
Oxygen rates
6 - 11 L/min
60 - 75%
Venturi mask, aerosol mask, face tent, tracheostomy collar, T-piece
This type of oxygen delivery system
High flow
___ mask works by pulling in a proportional amount of room air for each liter flow of oxygen
Venti (most accurate)
Which high flow mask type uses humidity
All but venturi
Face tent, aerosol mask, trach collar, T piece
Type of mask for burn victims
Face tent
CPAP effect is to…
Used with these types of patients
Open collapsed alveoli / Hold open upper airways
Atelectasis, cardiac-enduced pulmonary edema, COPD, SLEEP APENA
No Valsalva maneuver, no sniff / blow nose, don’t sneeze with mouth closed
No NSAIDS
For this problem…
Broken nose
For Epitaxis this position
Upright & forward
Prevent blood from aspiration/ enter stomach
Apply dirext lateral pressure to the nose for Epitaxis for 10 minutes
Then apply ice
