Document Summary
Crackles: sort popping, crackly sounds caused by fluid in small airway or alveoli: occurs during inspiration, expiration or both. Wheezes: course, rumbling, low pitched: heard on expiration. Cyanosis: a blueish discoloration of the skin from poor circulation. Hyperventilation: the condition when you start to breathe very quickly. Hypoxia: a decrease in oxygen in the blood. Mechanics of respiration: four functions, supply oxygen to the body, remove co2, maintain homeostasis, maintain heat exchange, control of respirations. Involuntary control of respiration is controlled by the respiratory center in the brainstem. Vital signs: temperature, pulse notice rate and rhythm, respirations, blood pressure. Inspect the anterior and posterior chest: notice rate and rhythm of breathing, notice shape and configuration of spinous processes, note lifts and heaves, anterior-posterior vs transverse ratio. Palpation - posterior: assesses for symmetric posterior chest expansion at the level of t9 or t10.
