| Respiratory rate slower than 12 per minute (in adult) |
bradypnea |
| This respiratory pattern is rapid, deep, and labored, and is the eponymic description applied to respiratory effort associated with metabolic acidosis. |
Kussmal breathing |
| This respiratory pattern is characterised by abnormally shallow respirations (e.g. when pleuritic pain limits excursion) |
hypopnea |
| A regular periodic pattern of breathing, with intervals of apnea followed by crescendo/decrescendo seqence of respiration. |
Cheyne-Stokes |
| This is increasing difficulty in expelling air from lungs, respiration rate becomes increased and effort more shallow. |
air trapping |
| Irregular respirations varying in depth and interrupted by intervals of apnea, but lacking the repetitive pattern of periodic respiration. |
biot respirations |
| Respiratory pattern with significant disorganization with irregular and varying depths of respiration. |
ataxic respirations |
| This respiratory abnormal action suggests an obstruction to inspiration at any point in the respiratory tract; as intrapleural pressure becomes increasingly negative, the musculature "pulls back" in an effort to overcome blockage. |
retractions |
| When an obstruction is high in the respiratory tree (with tracheal and laryngeal involvement) this characteristic sound is heard. |
stridor |
| Seeing unilateral retractions without involvement of substernal notch is indicative of what? |
foreign body in one or the other of the bronchi |
| This crackly or crinkly sensation, which can be both palpated and heard indicates air in the subcutaneous tissue from a rupture somwhere in the respiratory system or by infectin with a gas producing organism. |
crepitus |
| A palpable, coarse, grating vibration, usually on inspiration suggests this, caused by inflammation of the pleural surfaces. |
pleural friction rub |
| Explain how to evaluate thoracic expansion, posteriorly, during palpation. |
Thumbs along spinous processed at the level of the 10th rib, with palms slightly in contact with the posteriolateral surfaces. Watch thumbs diverge during quiet and deep inspiration. |
| Where should thumbs and palms be placed during anterior palpation to assess thoracic expansion for symmetry? |
thumbs on costal margin and xiphoid process, palms touching the anterolateral chest |
| This is the palpable vibration of the chest wall that results from speech or other verbalization. |
Tactile fremitus |
| Where is fremitus best assessed on the chest? |
parasternally at the level of the 2nd intercostal space, at the level of the bifurcation of the bronchi. |
| Under what conditions would you expect to see decreased fremitus? |
emphysema, pleural thickening or effusion, massive pulmonay edema, or bronchial obstruction |
| Under what conditions would you expect to see increased fremitus? |
the presence of fluids or a solid mass |
| Hyperresonance may be indicative of what conditions? |
emphysema, pneumothorax, or asthma |
| Dullness of flatness on percusion may be associated with? |
atelectasis, pleural effusion, pneumothorax, or asthma |
| Descent of diaphagmatic excursion may be limited by what conditions? |
pulmonary, as a result of emphysema, abdominal, as in massive ascites or tumor, or superficial pain. |
| What is the normal diaphragmatic excursion? |
3-5cm |
| Total or partial collapse of the lung or a congenital condition characterized by the incomplete expansion of the lungs at birth |
atelectasis |
| The best place to listen to the middle lobe is in this location? |
axilla |
| This type of breath sound is low-pitched, low-intensity sound heard over normal lung tissue? |
vesicular |
| These sounds are heard over the major bronchi and are typically moderate in pitch and intensity. |
bronchovesicular |
| These sounds are high in pitch and intensity and are usually heard over the trachea. |
bronchial |
| sweet and fruity breath usually seen in what condition. |

| This sound of percussion is loud, low pitch, long, and hollow |

dull |
| This sound of percussion is loud, high pitched, medium duration, and drumlike. |
tympanic |

| This adventitious breath sound is characterised by high-pitched, discrete, discontinuous crackling. |
fine crackles |
| Persistent or progressive dilation of the bronchi or bronchioles as a consequence of inflammatory disease, obstruction, or congenital abnormality. |

Coarse crackles |
| This is a loud, low, coarse sounds like a snore most often on expiration; coughing may clear. |
Rhonchi |
| This musical like noise sounding like a squeak is most often heard during both inspiration and expiration; usually louder on expiration. |
Wheeze |
| This is a dry, rubbing, or grating sound, usually caused by inflammatin of pleural surfaces; heard during both inspiration and expiration. |

Bronchophony |
| More extreme bronchophony, where even a whisper can be heard clearly upon ausculation. |
