SaO2 or sO2
|
97-100%
|
|
PCO2
|
35-45 mm Hg
Respiratory |
|
HCO3
|
22-26
Metabolic |
|
Respiratory acidosis
|
PH low, PCO2 high
hypoventilation-shallow breathing CO2 retention Kidneys compensate by holding on to HCO3 |
|
Respiratory alkalosis
|
PH high, PCO2 low
hyperventilation...too much CO2 blown off Kidneys compensate by excreting HCO3 |
|
Metabolic acidosis
|
PH low, HCO3 low
Ketoacidosis-accumulation of acids Lungs compensate by hyperventilating ..blowing off CO2 |
|
Metabolic alkalosis
|
PH high, HCO3 high
accumulation of HCO3 Lungs compensate by hypventilation |
|
Hypoventilation AKA bradypnea
|
less than 16 breaths per minute.
|
|
Hyperventilation AKA tachypena
|
more than 20 breaths per minute.
|
|
Hyperpnea
|
increased depth of repsirations
EX. Kussmaul respirations |
|
Hypopnea
|
Shallow breathing
|
|
Apnea
|
no respirations at all
|
|
Cheyne-strokes
|
irregular breathing seen in some comatose patients
|
|
Hemoptysis
|
coughing up of blood
|
|
Hypoxemia
|
reduced oxygenation of arterial blood
|
|
Lower than normal V/Q
|
caused by less ventilation
ex...collapsed lung |
|
Higher than nomral V/Q
|
less perfusion
ex...pulmonary embolus |
|
Restrictive lung diseases
|
Inhalation problems
|
|
chest wall restriction
|
deformed...kyphosis
obese neuromuscular |
|
Acute epiglottis
|
inflammation of epiglottis
inspiratory stridor drooling |
|
pleural effusion
|
extra fluid in pleural space..pain upon deep breaths
|
|
Pneumothorax
open and closed |
presence of air in pleural space....disrutption of negative normal pressure.
|
|
Pulmonary fibrosis
|
excessive amount of fibrous connective tissue caused by scarring.
|
|
Pneumonia
|
acute infection of the lower respiratory tract by bacteria, viruses, fungi, or parasites.
infiltrates accumulate in alveoli..infiltrates cause atelectasis when portions of lung tissue collapse. |
|
Tuberculosis
|
sealed off portions of bacteria
|
|
Obstructive lung diseases
|
asthma,bronchitis, emphysema, copd, and systic fibrosis
|
