gas exchange - N220L Flashcards
hypoxia
lack of oxygen at cellular / tissue level
hypoxemia
lack of oxygen in the arterial blood
hypoventillation
decreased minute volume (inc CO2); resp. rate abnormally low; depth of ventilation depressed; hypercarbia may occur; resp. insufficient to prevent CO2 retention
respiratory failure
acute or chronic loss of pulmonary function that results in hypoxemia or hypercarbia
respiration measurement can be affected by?
exercise, smoking, pain, anxiety, meds, body position, neurological injury, hemoglobin fn
Cheyne-Stokes respiration occurs when
there is a decreased blood flow or injury to the brain stem
Cheyne-Stoke resp characteristics
respiratory rate and depth are irregular; alternating apnea and hyperventillation
Kussmaul’s respiration
respirations are abnormally deep, regular and increased in rate
Biot’s respiration
respirations are abnormally shallow for 2-3 breaths followed by apnea
acceptable range of respiratory rate for newborn
35-40 breaths per minute
infant/ 6 mo resp rate
30-50
toddler / 2 yrs resp rate
25-32
child resp rate
20-30
adolescent resp rate
16-20
adult resp rate
12-20
