Stack #121975
| Question | Answer |
|---|---|
| Ventilation | inflow, outflow of air between the atmosphere and the lung alveoli |
| respiration | gas exchange between air and blood |
| oxygen transport | diffusion of O and CO2 between capillary wall and interstitial fluid |
| tidal volume | volume of air inspired an expired with normal breath. average 700. don't count dead space |
| inspiratory reserve volume IRV | extra volume of air beyond tidal volume (3000 ml) |
| expiratory reserve volume ERV | amt of air that can still be expired after normal tidal volume (1000 ml) |
| residual volume RV | air still remaining in lungs after the most forceful expiration (1500 ml) |
| KNOW dead space | air in throat area that does nothing to benefit lungs because doesn't go to lungs |
| IC=? | TV + IRV (3500 ml) |
| functional residual capacity (FRC) = ? | erv + rv |
| total lungl capacity (TLC) | maximum volume to which the lung can be expanded w/ the greatest inspiratory effort |
| vital capacity (VC) =? | IRV + TV + ERV (4500 ml) |
| respiration | gas exchange |
| oxygen transport | via blood through capillaries. |
| airway resistance caused by | obstruction, asthma, mucous chronic bronchitis, pneumonia |
| diffusion | breathing |
| perfusion | oxygen into capillaries |
| Neurologic control of respiratory center | pons and medulla oblingata |
| gerontologic changes | alveolar loses surface tension |
| steroid oral & IV | blue in face, bad skin, increase in sugar. Solumedrol is given IV |
| steroid | antiinflammatory. rinse mouth after inhalation steroids to prevent thrush |
| thorcic excursion | thorax is going out |
| percussion | inhale and hold, percuss down one side of back, pen mark, exhale and hold, percuss, pen mark. this marks the diaphragm location |
| interventions | oxygen, ascultate, meds, cough and deep breath, pulse ox, accessory muscles, neck veins, sternal retraction (can see costal spaces) |
| nursing diagnosis | impaired gas exchange, ineffective breathing pattern, tissue perfusion |
| albuterol | beta antagonist. It stops the SNS which constricts the lungs so this drug DIALATEs, opens the airways |
| COPD | chronic bronchitis & emphysema |
| tracheostomy | hole in trachea for proper ventilation for longterm |
| who has chest tubes | open heart, pneumothorax (air in pleural space) & hemothorax (blood in pleural space) which collapes the lung |
| pleurothorax is air in pleural space where? | in upper lung |
| hemothorax blood in pleural space where? | in lower lung |
| right lung lobes | 3 lobes. when listening to breath sounds, ICS 4 and 6 (not lateral) must be heard to listen to right |
| left lung lobes | 2 lobes because the heart is there |
| trachea | from trachea, lungs split into R/L bronchi. Right is straighter so |
| oxygen transport | via blood, capillaries. |
| alveoli | gas exchange |
| oxygen transport | breath, to alveoli crosses alveoli capillary membrane to blood, pulmonary artery is deoxygenated to lungs to pulmonary vein to left atrium to mitral valve to left ventricle to aorta |
| atelectasis | alveoli not opening |
| airway resistance | obstruction, asthma, obstruction, chronic bronchitis, pneumonia |
| non-compliant lungs | lungs not compliant |
| tital volume | amount of air in and out on a normal breath. 10ml/kg |
| dead space | from nose and mouth to trachea. air that does not contribute at all |
| FEV1 | forced expiratory volume in one SECOND. In pulmonary function tests. Key to determine COPD |
| COPD test | FEV1 is decreased, very important value |
| perfusion | (getting oxygen into capillaries |
| V/Q scan measures what? | measures ventilation (air in) vs air getting into blood stream (perfusion) |
| V/Q scan test for what? | Pulmonary emboli (PE) |
| V/Q scan how? | scan, breath radioactive gases, scan |
| oxygen content | FiO2. 21% is in room air. |
| oxyhemoglobin | Sat O2 and PaO2. eg Sat O2 of 90%= PA (arterial) O2 of 60%. Hemoglobin ox sat is very low is ox sat is low |
| neurologic | resp center is in brain, stroke, C2 fracture will stop breathing |
| alveoli | loses elasticity as we age |
