Means ventilation/perfusion mismatch
A cause of hypoxemia, pulmonary capillary blood, which flows by alveoli that are not ventilated, does not pick up and O2 and thus returns to the systemic circulation unchanged.
Causes hypoxemia, is abnormalities in the lung structure that slow the diffusion of O2 from the inhaled gas through the alveolar-capillary membrane.
Hypoxemia caused by low breathing
A patient with lung disease will usually have hypoxemia due to both ______ and ______.
V/Q mismatch and hypoventilation
hypoxemia can be cause by breathing in____ or from a faulty machine?
Normal value of SaO2
is an index of actual amount of O2 bound to Hb and is expressed as a percentage of the total capacity.
True reliable SaO2 can only be calculated by a?
PaO2 and SaO2 have a non-linear relationship. True or false?
Normal value of HbCO.
is a reflection of quantity of CO bound to the Hb molecules and can be obtained only from the co-oximeter
is a highly diffusable, odorless, and colorless gas that has an inffiinty for Hb 200 to 250 times that of O2.
Inhalation of gas containing CO will result in shifts of the oxyhemoglobin curve dissociation curve. It will curve to the ____?
Presence of CO does what to the CaCO2?
CO promoted Tissue
It reduces the O2 carrying capacity of the Hb and inhibits unloading of O2 at the tissue.
Occurs when the respiratory system fails to oxygenate arterial blood adequately.
Large P(A-a)O2 indicates?
severe respiratory abnormality.
Hypoxemia occuring with a normal P(A-a)O2 may be the result of?
if the sum of PaO2 and PaCo2 is 110 - 130 mmHg then the cause of hypoxemia is?
if the sum of PaO2 and PaCO2 is less than 110 mmHg then the cause of hypoxemia is?
defects in the lung's ability to oxygenate the blood.
if the sum of PaO2 and PaCO2 is greater than 130 mmHg than the cause of hypoxemia is?
is on supplimental breathing or an error.
Assessment if the Hb concentration from either the complete blood cell count or co-oximetry measuremtn is crucial for identiofying the potential for?
A reduction of CaO2 can occur with?
is identified when trhe O2 level drops below 90%
Cyanosis is not recognized in patients with ____.
remove a small amount of acid but help restore the buffer capacity of the body fluids by adding HCO3.
Resp. and renal disfunction may cause.
is an abnormal condition in which there is a primary reduction in alveolar ventilation relative to the rate of CO2 production. It indicates that ventilation is inadequate.
in acute respiratory acidosis Plasma HCO3 increases ____ for every 10-15mmHg that PaCO2 increases.
In chronic respiratory acidosis plasma HCO3 increases ____ for every 10-15 mmHG that PaCO2 increases.
is an abnormal condition in which there is a primary increase in alveolar ventilation relative to the rate of CO2 production.
Acute Resp. Alkal. will result in a decrease of HCO3 of ____ for every 5mmHg of PaCO2 decreases.
Chronic resp. alkal. will result in a decrease of HCO3 of _____ for every 10mmHG of PaCO2 decreases.
is a generic term that includes spirometry, flow volume loop, before and after bronchodialtor inhalation, lung volume studies, and diffusion capacity testing.
Pulmonary function testing.
is the most important factor influencing lung size and predicted values.
Weight is not a factor in predicting lung volume until the BMI is.
Average Tidal Volume?
Normal VE is?
