Respiratory Lecture part 3 Flashcards
We do percuss in those 6 spots and it’s a technique to find whether there is a solid mass or density in there
You want to not hear anything you want it to be hollow because air is in the lungs…air is coming…air is going out…its hollow its exactly what you want…its normal
Pleural effusion is fluid in the lungs
Lets say we have a heart failure patient and they have accumulated fluid in their lungs and maybe there is more fluid in the left than there is on the right so you may have fluid halfway up on the left and none on the right…your going to percuss and your going to hear the dullness in the lower and middle lobes as to how much fluid is in there and again that is important because then we are going to prescribe diuretics to pull that fluid off and treat that heart failure exacerbation
Dullness for dense mass in the lungs
Starting upper left then upper right and follow down right…left…left…right…the whole point of this is your comparing side to side…your trying to figure out is there symmetry or not…notice where his lung fields end…here’s the scapula…your just a little bit lower than the scapula…this is not lower back people this is middle back and the lower lobes of the lungs
At each location it’s a full deep breathe in through them the mouth. The mouth needs to be opened…this is not nose breathing….you need a full deep breath in and deep breath out to hear that air come in and out….wheeze and crackles
Don’t need to know rhonchi
____________=listening to someone repeat the letter E when your listening to their lungs and it resonates back to the letter A so based on how the air goes through the lungs it changes the sound
Egophany
Wheezing is what happens in those bronchi…constriction…so that’s typically in our asthma folks
___________ are more of fluid…if you have fluid going into those alveoli as air comes in its popping and that’s what you hear is those crackles…it sounds like wrinkling cellophane and crinkling paper
Crackles
_____________:Created when air is forced through bronchial passageways narrowed by fluid, mucus, or pus or by the popping open of previously deflated alveoli; can be a sign of infection, inflammation of congestive heart failure (CHF); short,popping sounds
Crackles
______________:airway narrowing, usually a sign of asthma but can also occur w/other causes of airway narrowing, such as COPD and bronchitis; high-pitched musical sounds
wheezes
In spirometry we are measuring forced vital capacity so that’s the total volume of air that can be exhaled after a deep inhalation in a normal forced vital capacity is 4 to 5 liters…you are essentially taking in the biggest deepest breath possible and your blowing it into this machine until you can’t blow out anymore air…as much air as you can get out….____to _______liters is what is normal
4 to 5 litters
Forced expiratory volume in one second…so that is as your breathing out as hard and as fast as you can its that first second of air that volume typically that’s more than 80% of the forced vital capacity
