Clin Skills 5 Basic Airway Flashcards
Used to prevent gastric distention that can accompany intubation and ventilation.
Technique:
Apply slight pressure anteriorly over cricoid cartilage.
Closes off esophagus.
Sellick’s Maneuver
aspiration of HCl is called __ syndrome
Mendelson’s syndrome
Must generate vacuum levels of at least __mm Hg and flow rate of __liters per minute.
300
30
limit each attempt of suctioning to:
10 seconds
Nasal cannula delivers oxygen at what flow rate?
1 to 6 liters/minute
For use with patients:
With mild to moderate hypoxia.
Who are prone to carbon dioxide retention.
Who feel frightened or suffocated by a mask.
Who are experiencing nausea or vomiting.
Nasal cannula
Simple face mask:
Delivers 40 to 60% oxygen at what flor rate?
8-12 liters/min
Nonrebreather mask
Can deliver 60 to 100% oxygen at what flow rate?
10 to 15 liters/minute
How long it takes a blood gas to change, to see how well O2 therapy is working:
no history of lung ds: 10 minutes
COPD patients: 20 minutes
Oxygen device For use with patients suffering from: Severe hypoxia. Respiratory compromise. Shock. Acute myocardial infarction. Trauma. Carbon monoxide poisoning.
NRB
Venturi Mask flow rate?
2-15L/min
start at 2, work your way up to 15.
Made up of oxygen tubing, face mask
Room air entrained into the mask by calibrated device which mixes it with oxygen.
Used for COLD patients requiring exact oxygen concentrations.
Venturi mask:
How to calculate ideal body weight
If pt needs continued vent’n, consider your lungs are fit to your ideal body weight.
So must calculate ideal body-weight? How to do it???
for 5 feet: 45.5kg for women; 50 kg for men… + 2.3kg for each additional inch of the remaining height.
Cm/2.54 into inches. Convert inches into first 5 feet, and then the inches above 5 feet.
For me (5’10”): 50kg + 2.3 x 10 = 73kg
how to calculate tidal volume
10 X IBW, then round it to nearest 50.
ex for me: 10 x 73kg = 730…round down to 700 cc’s.
Most patients who need this will prob have a high CO2, so when picking resp rate..you’d choose it towards the higher end (20 breaths/min) to reduce the resp acidosis.
*Know the oxy-hemoglobin association curve.
X axis: increased H+ concentration
It’s better for a patient to be acidotic than aklalotic, b/c if alkalotic they can’t deliver O2 to tissues b/c they’re holding onto it too tightly.
What do you set positive expiratory pressure at? _ cm of water.
Say: 5cm of water. (Caveat to this: patient who is still hemodyanimically unstable (hotn) – the increased intrathoracic pressure will decrease venous return to heart. It also causes intraventricular paradoxical motion.)
