- apnea
Answer absence of breathing
- bradypnea
Answer slow rate or depth of breathing
- dyspnea
Answer difficult or labored breathing
- hyperventilation
Answer increased rate and depth of respirations
- hypoventilation
Answer decreased rate and depth of respirations
- hypoxemia
Answer deficient oxygenation of blood
- hypoxia
Answer inadequate amount of oxygen available in to the cells
- orthopnea
Answer 1 / 3
type of dyspnea when lying flat; patient can only breath when sitting up or in tripod position
- tachypnea
Answer rapid rate of breathing
- ventilation
Answer inspiration and expiration
- ventilation is determined by
- increased CO2 in arterial blood stimulates...
Answer compliance airway resistance accessory muscles force exhalation
Answer increased inspiration
- diffusion
Answer movement of O2 and CO2 between alveoli and capillaries (from higher pressure to lower pressure)
- perfusion
Answer delivery of oxygenated blood to body tissues
- O2 transport is affected by
Answer amount of O2 entering lungs (ventilation) pulmonary circulation
adequacy of diffusion amount of hemoglobin to carry O2 2 / 3
cardiac output to transport blood to body tissues peripheral circulation
- problems with ventilation, diffusion, or perfusion lead to...
Answer hypoxia
- acute hypoxia
Answer dyspnea increased BP
increased RR increased HR pallor cyanosis anxiety restlessness confusion drowsiness
- chronic hypoxia
Answer effects seen in all body systems- headache chest pain clubbing weakness muscle pain decreased urinary output (dehydration) constipation anorexia
- cardiac output
- stroke volume
Answer amount of blood ejected from left ventricle/min (normal= 5L/min) CO= stroke volume x heart rate
Answer amount of blood ejected with each heart beat
affected by preload (volume), afterload (resistance), myocardial contractility
- purpose of surfactant
