High pitched musical sound heard on exhale. Usually in asthma or COPD. Indicates bronchial constriction.
Wheezing
True or false: Oxygen requires a doctor order
True
Nose bleed
Epistaxis
Dipenhydramine
Cetirizine
Loratadine
H2 receptor antagonist
Administer 1000 mL lactated ringers q 10 hrs.
? mL/hr
1000 mL / 10 hrs = 10 mL/hr
Wet sounds. Indicated fluid in the lungs. Heard in pneumonia and Congestive heart failure.
Rales/ Crackles
Site of oxygen/ CO2 exhange
Alevoli
A chronic inflammatory disease of the airways that causes hyper responsiveness, mucosal edema, and mucous production
Asthma
Albuterol, metaproterenol, salmeterol, terbutaline
bronchodilators
Administer D5 1/2 NS at 30 mL/hr. The drop factor is 60 drop/mL
?drops/min.
1 mL 1 hr 60 min 60
= 30 gtts/min
Airway obstruction. This is an emergency!
Stridor
Most common method of oxygen delivery, likely at 2 LPM
Nasal cannula
Cough and sputum production for at least 3 months in each of 2 consecutive years
Ciliary function is reduced, bronchial walls thicken, bronchial airways narrow, and mucous may plug airways
Alveoli become damaged, fibrosed, and alveolar macrophage function diminishes
The patient is more susceptible to respiratory infections
Chronic bronchitis
beclomethasone, budesonide, fluticasone, prednisone, prednisolone, methylprednisolone
corticosteroid
Administer 250mL in 90 minutes.
?mL/hr
?mL/hr: 250mL 60 mins
______ x ________ = 15000//90
90 mins 1 hr
= 166.66 = 167 mL/hr
Rhonchi
Too much oxygen will cause a patient with this condition to suppress their drive to breath.
COPD (Chronic Obstructive Pulmonary Disease)
Abnormal distention of air spaces beyond the terminal bronchioles with destruction of the walls of the alveoli
Decreased alveolar space causes an increase in “dead space” and impair oxygen diffusion
Reduction of the pulmonary capillary bed which increases pulmonary vascular resistance and pulmonary artery pressure
Hypoxemia
Increased pulmonary artery pressure causes heart failure
Emphysema
ethambutol, isoniazid, pryazinamide, rifampin
TB medications
Administer D5LR at 75 mL/hr. The drop factor is 10 drops/ml
? drops/min
?gtts/min: 10 gtts 75 mL 1 hr
______ x _____ x _____
1 mL 1 Hr 60 min

No sounds
Concentration of 50% or more over long periods of time.
Symptoms- sub sternal discomfort, paresthesia, dyspnea, restlessness, fatigue, malaise, progressive resp. difficulty, difficulty, hypoxemia, atelectasis, and alveolar infiltrates on X-ray
Oxygen toxicity
Closure or collapse of the alveoli. Can be acute or chronic
Atelectasis
ipatropium, tiotropium
anticholinergic
Administer IVPB 50mL in 30 minutes.
? mL/hr
?mL/hr = 50 mL 60 min
