Document Summary
Normal breath sounds: bronchial: loud, high pitch, trachea. Vesicular: soft and low, soft blowing, over the lesser bronchi. Adventitious breath sounds: crackles/rales: fine are deflated alveoli popping sounds, coarse air bubbles louder upon inspiration. O2 therapy: nasal cannula: 1-6l/min, 24-44% those with copd = 1-2l. Face mask rebreather: 5+ l/min, 40-60%, they can rebreathe trapped co2. Face mask non-rebreather: 6-10l/min, 60-100%, minimizes rebreathing co2. Venturi mask: controlled concentrations, you can gradually increase/decrease concentrations. for copd. Define: apparent life threatening event: sudden, frightening event where an infant experiences a combo of apnea, changes in color, changes muscle tone and choking/gagging/coughing, that requires significant interventions. Brief resolved unexplained event: new term for alte, an event that lasts less than a minute, usually seen in infants; stops breathing, has a change in muscle tone, turns pale or blue in color, or is unresponsive.
