Venturi Mask
most acurate O2 delivery method
Non-rebreather
60-100% oxygen delivery
Simple face mask
8-10 liters, at least 5L to flush out own carbon; 40-60%
Nasal Cannula
1-6 liters ; 20-40%
Partial rebreather
6-15 liters/minute ; 70-90%
Inspiration
diaphram contracts and flattens out, increasing the length of the thoracic cavity, intercostal muscles contract, elevating the ribs and increasing the diameter of the thoracic cavity.
Expiration
diaphram and intercostal muscles relax; decrease in size of the thoracic cavity increases pressure, and air moves out of the lungs.
Bronchial sounds
heard over the sternum, last longer during expiration than inspiration; loud, high pitched, tubular, hollow-like sounds.
Bronchovesicular sounds
heard over the anterior one-third of the chest near the sternum and around the scapula posteriorly; medium pitch and intensity with inspiration- expiration being equal in duration.
Vesicular sounds
heard over the majority of the lungs; soft, low-pitched sounds, heard best during inspiration and may be audible during expiration.
Normal breath sounds
bronchial, bronchovesicular, vesicular.
Abnormal breath sounds
fine crackles, coarse crackles, sonorous wheezes, sibilant wheezes, pleural friction rub, stridor.
