Stack #122223
a MCPHS- Provider I- Ch 21 Assessment of Respiratory Function
| Question | Answer |
|---|---|
| Lower Respiratory Tract function | Gas exchange |
| Lobes r/t Left lung | Left lung has Less lobes(2) |
| Respiration | Gas exchange b/w air and blood, Gas exchange b/w blood and cells |
| Diffusion | oxygen-carbon dioxide exchange |
| Causes r/t Increased airway resistance | Bronchial contraction(asthma), Thickened mucosa(chronic bronchitis), Obstruction, Decreased lung elasticity(emphysema) |
| Pulmonary perfusion | Blood flow thru pulmonary circulation |
| Tidal volume | Volume of air inhaled/exhaled w/each breath |
| Expiratory reserve volume | Max volume exhaled forcibly after normal exhalation |
| V/Q imbalances d/t | Inadequate ventilation, Inadequate perfusion, Both |
| 2 ways O is carried in blood | Dissolved in plasma, Hemoglobin |
| PaO normal values | 80-100 mm Hg |
| Respiratory function r/t Aging | Reduced surface area, elasticity & vital capacity, Increased dead space |
| Major S/Sx r/t Respiratory disease | Dyspnea, Sputum production, Chest pain, Clubbing, Hemoptysis, Cyanosis |
| Acute vs. Chronic lung diseases r/t Dyspnea severity | Acute are more severe |
| Sudden dyspnea r/t Immobilized Pt's | Pulmonary embolism |
| Orthopnea found in Pt's w/ | Heart disease, COPD |
| Dyspnea w/expiratory wheeze | COPD |
| Wheezing r/t Asthma | Present during inspiration and expiration |
| Other disorders that may cause dyspnea | Cardiac disease, Anaphylactic reactions, Severe anemia |
| Relief of dyspnea r/t Resting Pt's | High Fowler's(head elevation), Oxygen administration |
| Cough d/t | Irritation of mucous membranes in respiratory tracts |
| Cough in morning w/sputum | Bronchitis |
| Purulent sputum d/t | Bacterial infection |
| Frothy, pink sputum d/t | Pulmonary edema |
| Hemoptysis | Expectoration of blood |
| Late indicator of hypoxia | Cyanosis |
| Barrel chest d/t | Emphysema |
| PaCO r/t Hyperventilation | Decreased levels |
| Hyperventilation r/t Severe acidosis | Kussmaul's respiration |
| Alternating episodes of apnea w/periods of deep and shallow breathing | Cheyne-Stokes respiration |
| Wheezes d/t | Bronchial wall oscillation, Changes in airway diameter |
| Wheezes usually heard during | Expiration |
| More conclusive- ABG vs. Pulse oximetry | ABG |
| Pt cannot be discharged from recovery area until | Cough reflex & Respiratory status return |
