27 Cards in this Set

  • Front
  • Back
Pa02 or pO2
80-100 mm Hg
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
