Flashcards in Thorax and Lungs Deck (17)
Difficulty breathing when supine
Paroxysmal Nocturnal Dyspnea
Awakening from sleep with SOB and needing to be upright to achieve comfort.
a grating sound or sensation produced by friction between bone and cartilage or the fractured parts of a bone.
presence of air or gas in the cavity between the lung and chest wall causing lung atelectasis
Ask the patient to repeat the words "ninety nine". If clear, you can suspect increased lung density as with Pneumonia, edema, or pulmonary fibrosis. The lungs are being pushed on.
Ask the patient to say "eee" as you listen to the lungs. "eee" becomes an "aaaa" in the compressed of consolidated lung and indicated pathology.
Ask the patient to whisper "1,2,3" if you can clearly hear the words, this indicated even slight compression or consolidation.
Forced Expiratory Time
The number of second that it takes for ta person to exhale from total lung capacity to residual volume
Forced vital capacity
Measure with spirometer. The total volume of air exhaled
The forced expiratory volume in 1 second.
Ratio between FVC and FEV1
75% or better for healthy
noninvasive method to assess arterial oxygen saturation (SpO2) The healthy persons SpO2 is usually around 99-100% Need to be evaluated in the context of the persons hemoglobin level, acid base balance, and ventilatory status.
6-minute walk test
6 MWT, safer, simple, inexpensive, clinically significant, Aging adult. This is to see how far the person can go in 6 minutes. If they can walk 300 meters or more they are more likely to engage in activities of daily living.
AP-transverse diameter ratios (child/adult)
Child: Increased until about 6yo (after indicated chronic asthma or cyctic fibrosis)
Adult: 1:2 ratio
Obligate nose breathers. Primary Muscle of inspiration is the diaphragm, intercostal muscles are not developed yet. There will be abdominal expansion
Little to no thoracic expansion.
High pitched, inspiratory, crowing sound. Indication of foreign body obstruction, croupe, and epiglottitis
