T7-8 interspace - ANSWER-location for most thoracentesis

visceral pleura - ANSWER-serous membranes that cover the outer surface of each lung
parietal pleura - ANSWER-serous membrane that covers the inner rib cage and upper surface of the
diaphragm
T/F there are no pain receptors in the visceral pleura - ANSWER-TRUE
how lungs function - ANSWER-- inhale: air enters lungs
- oxygen from air moves into blood
- CO2 moves from blood to lungs and is exhaled
diaphragm - ANSWER-major muscle, separates thoracic cavity from abdominal
inhalation - ANSWER-- diaphragm contracts, gets smaller, decreases pressure in thoracic cavity -->
air able to come in
,exhalation - ANSWER-diaphragm expands, gets bigger, moves up --> air out
pursed lip breathing - ANSWER-- allows for slower release of air with expiration
- improves ventilation
- releases trapped air in lungs by slowing breathing
- keeps airways open longer and decreases work of breathing
- prolongs exhalation and slows breathing rate
- relieves feeling of SOB
when can you see pursed lip breathing - ANSWER-can be seen in COPD, asthma (to help with
dyspnea) normal breathing (relaxation/mediation)
deviated trachea - ANSWER-caused by abnormal pressure in chest cavity or neck
causes of deviated trachea - ANSWER-- PTX (most common)
- trauma to chest wall/lungs/neck
- tumors
- mediastinal lymphoma
- pleural effusion
symptoms associated with deviated trachea - ANSWER-cough, difficulty breathing, wheezing, chest
pain
- using accessory muscles, having retractions
deviated trachea pulled towards pathology - ANSWER-- generally occur with problems inside lungs
- ex: atelectasis (collapse), fibrosis (thickening/scarring), pneumonectomy
deviated trachea pushed away from pathology - ANSWER-- occur outside lungs
- ex: massive pleural effusion, tension PTX, mass (neck or mediastinal in location)
chest expansion - ANSWER-- evaluating for symmetrical movement of the chest wall with inspiration
- more concerned with decreased movement which signifies that the lung is not expanding as normal
when will asymmetry be noted - ANSWER-tumor, pleural effusion, bronchial obstruction
what part of the stethoscope do you use to auscultate lungs - ANSWER-diaphragm
limitations to percussion - ANSWER-- penetrates 5-7 cm deep
- determine if air filled, fluid filled or solid
- this technique will miss deep seated lesions
- sometimes unable to penetrate due to body habitus
"percussion is not about how ______ you strike it but ______ on fingers" - ANSWER-hard, pressure
what can be beneficial when percussing - ANSWER-- have pt lean forward and slightly cross arms
- separates scapular and opens up the available intercostal spaces
resonant - ANSWER-normal, healthy lung
dull/flat - ANSWER-- fluid or solid tissue replace air-filled lungs
- pathological cause: pleural effusion, lobar pneumonia, hemothorax, tumor
hyper-resonate - ANSWER-- increase air in lungs
,- pathological cause: unilateral- PTX, bulla (increased air where not expected)
generalized: COPD or asthma
tympanic - ANSWER-- excessive air in chest
- pathological cause: large PTX
diaphragmatic excursion - ANSWER-- assesses functionality of diaphragm
- evaluate one side to another
- normal excursion: 3-5.5 cm
-decreased: pleural effusion, atelectasis, phrenic nerve paralysis
what does positive egophony signify - ANSWER-consolidation, as the sound transmits through the
area where air-filled space has been replaced with fluid/solid space, it changes the sound heard
what does positive bronchophony signify - ANSWER-air-filled lung space replaced by fluid or solid-
space and this allows sound to be transmitted better
what does positive whispered pectoriloquoy signify - ANSWER-sound has better transmission and
sound is detected
