|
The purposes of breathing are to provide ? for tissue perfusion so that cells have enough oxygen to metabolize and generate ? and to remove ? the waste created by metabolizm.
|
oxygen,
energy, CO2 |
|
|
The upper airway consist of the ?, the ?, the ? and the ?
|
nose,
sinuses, pharynx, larynx |
|
|
The nose is the organ of ? with receptors from cranial nerve ? the olfactory nerve.
|
smell,
one |
|
|
The source of Oxygen for all body cells is the ? we breathe into our lungs.
|
air
|
|
|
Some health problems reduce the body's ability to ? when oxygen need is greater than basic(basal) levels required.
|
compensate
|
|
|
In a person with asthma the ? needs to compensate more to increase delivery of the set amount of oxgen taken in because the lungs can't keep up.
|
heart
|
|
|
When a person has a cardiac problem and the HR alone cannot increase O2 delivery during exercise, the ? rate would have to increase more than usual to keep oxygen delivery in balance with oxygen need.
|
respiratory
|
|
|
The best way to eliminate pneumonia, which could take days is ? therapy. Other ways involve reducing O2 need to the lowest possible level by having the pt ? and improving O2 intake by increasing the % of O2 in the air with ? therapy.
|
drug,
rest, oxygen |
|
|
breathing; the exchange of air between the lungs and the environment, including inhalation and exhalation is ?
|
ventilation
|
|
|
PCO2 > 45 mm Hg indicates alveolar ?
|
hypoventilation
|
|
|
• PCO2 < 35 mm Hg indicates alveolar
|
hyperventilation
|
|
|
In acute respiratory failure a blood gas is
necessary to assess the ? to determine if inadequate ventilation contributed to the hypoxemia. |
PaCO2
|
|
|
Conditions altering ventilation include Decreased ? production, ?, Obesity, ? Restrictive disorders
Pulmonary vascular ? Air, blood or excess fluid in pleural space. |
surfactant,
atelectasis, musculoskelatal, engorgement |
|
|
There is no problem with ventalatioin with a PE there is a problem with ? and ?
|
diffusion,
perfusion |
|
|
? is the blood supply to an area. Blood carries gases so that they can be ? in and out of the pulmonary ?
|
Perfusion,
diffused, capillaries |
|
|
Narrowing of airways can include increased ? and ?
Also Obstructive Disorders such as B-A-S-E-F. |
secretions,
bronchospams, Bronchitis, Asthma, Sleep Apnea, Emphysema, Foreign body |
|
|
Ventilation and Perfusion Occur ?
|
Simultaneously
|
|
|
Movement of gases between the alveoli,
plasma, and red blood cells is ? |
Diffusion
|
|
|
Diffusion of oxygen from alveoli to
capillary determines the patient’s ? status |
oxygenation
|
|
|
? is assessed by PaO2 and oxygen saturation (SaO2)
|
Diffusion
|
|
|
CO2 is 20 times more diffusible than ? so a diffusion
problem causing hypoxemia does not result in the same problem with ? retention (hypercapnia) |
02,
CO2 |
