produces surfactant - ✔✔Lower airway and tracheobronchial tree
___ are hair cells that line airway system which sweeps out bacteria and pathogens -
✔✔Mucociliary clearance
What population doesn't have mucociliary clearance? - ✔✔Smokers
___ reduces the surface tension between the moist membranes and prevents alveoli from
collapsing - ✔✔Surfactant
___ lobes are auscultated on the back of the patient - ✔✔posterior
The ___ lobe is auscultated anteriorly - ✔✔middle
The ___ is a thin layer of tissue that covers the lungs and lines the interior wall of the chest
cavity - ✔✔pleura
The ___ makes pressure change easier in the lungs and allows them to expand and keeps
them 'slippery' - ✔✔Serous membrane
The ___ pleura covers the lungs and the ___ pleura lines the thoracic cavity - ✔✔Visceral;
parietal
,___ is the active phase of breathing and the diaphragm flattens and allows air to rush into the
lungs - ✔✔Ventilation
___ is the passive phase of breathing when the diaphragm flattens and air moves out of the
lungs - ✔✔Expiration
True or false: the thorax is a positive pressure space - ✔✔False - its negative
Patients who have a change in surface area available due to water/fluid in the lungs -
✔✔COPD, chronic asthma pts
Factors influencing diffusion of gases in lungs - ✔✔- change in surface area available (EX:
edema)
- Thickening of alveolar capillary membrane (EX: chronic asthma)
- Partial pressure (EX: pressure change due to elevation and less oxygen, making alveolar less
expandable)
- Solubility and molecular weight of the gas (EX: smoke inhalation)
___ of the lungs can be altered by elevation. What does it do to the alveoli/ - ✔✔partial
pressure. Makes alveoli less expandable
What type of patients have problems with solubility and molecular weight of the gas in the
lungs? - ✔✔Burn patients and smokers
___ measures how accurately oxygen is carried in the body - ✔✔Hemoglobin
What is oxygen carried in the body? - ✔✔via plasma and RBC
What are the RBC's that oxygen is carried called? - ✔✔oxyhemoglobin
What are the RBC that carry CO2? - ✔✔carboxyhemoglobin
, ___ is an inadequate amount of oxygen available to the cells - ✔✔hypoxia
___ is difficulty breathing - ✔✔dyspnea
In ___ the heart cells are dead and the damage is irreversible; whereas in ___ the cells still
have an opportunity to oxygenate - ✔✔ischemia; hypoxia
When checking for hypoxia, what are the 2 places on a patient you should look at? - ✔✔Nail
beds and gum lines
In patients with COPD, tissue swelling, asthma, and an excessive amount of secretions and
inflammation they are experiencing ___ - ✔✔dyspnea - difficulty breathing
Patients with ___ use accessory muscle which looks like belly breathing - ✔✔dyspnea
In ___ there is a decreased rate or depth of air movement into the lungs which may be caused
by giving patients too much narcotics - ✔✔Hypoventilation
True or false: Some people may show no symptoms if they are having a heart attack and
women usually show less signs - ✔✔True
___ is dead of cardiac tissue (myocytes) due to enough decreased oxygenation -
✔✔Myocardial ischemia
Factors affecting cardiopulmonary functioning and oxygenation - ✔✔- level of health
- developmental considerations
-medication considerations
-lifestyle considerations
- environmental considerations
- psychological health considerations
