|---|---|---|---|---|---|
| Difference of pediatric airways? | 1. smaller jaw 2.larger tongue 3.narrowest part of the pediatric airway is cricoid cartilage 4. epiglottis is rounder and floppier
🗑
|
||||
| what is the definition of RESPIRATION? | the exchange of gases between living orginisms and its environment
🗑
|
||||
| what is the definition of VENTILATION? | the mechanical process that moves air into and out of the lungs
🗑
|
||||
| normal ranges for PaCO2? | 35-45 torr (average 40)
🗑
|
||||
| does hyperventilation lower or raise CO2 levels? | hyperventilation LOWERS CO2 levels due to increased respiratory rates/deeper respirations.
🗑
|
||||
| will a patient with PaCO2 of 30 be alkalotic or acidic? | pt will be alkalotic thus decreasing respiratory rate
🗑
|
||||
| baroreceptors in carotid body regulate? | BP
🗑
|
||||
| chemoreceptors are regulated by? | PaCO2,pH,CSF
🗑
|
||||
| Hering-Breuer Reflex? | triggered to prevent over-inflation of the lungs. Pulmonary stretch receptors present in the smooth muscle of the airways respond to excessive stretching of the lung during large inspirations.
🗑
|
||||
| Normal Respiratory rates? (adult,pediatric,infant) | adult 12-20 pediatric 18-24 infant 40-60
🗑
|
||||
| Dead space volume definition? (VD) | amount of gases in tidal volume that remains in the airway. (approximately 150 ml in adult male)
🗑
|
||||
| Total lung capacity definition? (TLC) | maximum lung capacity (average male 6 liters)
🗑
|
||||
| Tidal volume definition? (TV) | average volume of gas inhaled or exhaled in one respiration cycle (avergae adult male 500 ml)
🗑
|
||||
| Inspiratory reserve volume definition? (IRV) | the amount of air that can be maximally inhaled after normal inspiration
🗑
|
||||
| Most common cause of airway obstruction? | the tongue
🗑
|
||||
| Kussmaul's respiration | Deep,slow or rapid, gasping (common in DKA)
🗑
|
||||
| Cheyne-Stokes respirations | Progressively deeper,faster breathing alternating gradually with shallow,slower breathing (indication brain stem injury)
🗑
|
||||
| Agonal respirations | shallow,slow,or infequent breathing (indicating brain anoxia)
🗑
|
||||
| Airway sounds | stridor,wheezing,rales,rhonchi,snoring,crackles
🗑
|
||||
| Esophageal detector device test (bulb) | 1. if the bulb does NOT refill then incorrect placememnt. 2. if the bulb refills easilyupon release,indicates proper placement
🗑
|
||||
| OPA placement | insert with tip facing palate & rotate airway 180 degrees into position.
🗑
|
||||
| Cricothyrotomy anatomical landmarks | between the cricoid cartilage and the thyroid cartilage
🗑
|
||||
| cricothyrotomy Needle size | 14 G
🗑
|
||||
| cricothyrotomy procedure | make a 1 cm horizontal incision through the cricothyroid membrane
🗑
|
||||
| O2 regulator specs | green,chrom,white, 2:5 pin index
🗑
|
||||
| Chronic Bronchitis | Pathophysiology: results from increased mucus-secreting cell in respiratory tee. Alveoli relatively unaffected. Decreased alveolar ventilation. Physicla exam: often overweight,RHONCHI present,JVD, ankle edema, hepatic congestion, "BLUE BLOATER"
🗑
|
||||
| Chronic Bronchitis TX | maintain airway,position of comfort,monitor,IV,Meds (bronchodilators & corticosteroids)
🗑
