BLOOD GASES AND PH

WHAT IS THE NORMAL AVERAGE PH RANGE?

WHAT IS THE NORMAL AVERAGE PH RANGE?

7.35-7.45

AVERAGE FOR ARTERIAL BLOOD

7.4

THIS CONTRIBUTES TO THE NORMAL METABOLIC PROCESS AND PHYSIOLOGY OF VARIOUS CELLS AND TISSUES

BLOOD PH

TRUE OR FALSE. SLIGHT DEVIATION IN THE PH OF THE BLOOD WON’T HAVE ANY SIGNIFICANT CAUSE IN OUR BODY

FALSE

ACIDIC OR ALKALINE:

A PH OF <7.35

ACIDIC

ACIDIC OR ALKALINE:

A PH OF >7.45

ALKALINE

IN WHAT LEVEL OF PH RANGE COULD BE INCOMPATIBLE TO LIFE AND LEAD TO FATALITY?

PH OF LESS THAN 6.8 AND HIGHER THAN 8.0

PH IN OUR BODY IS MONITORED BY?

BUFFER AND ORGANS

THIS SERVES AS THE 1ST LINE OF DEFENSE AGAINST PH CHANGE

CHEMICAL BUFFERS

THIS IS THE FASTEST TO RESPOND (SECONDS TO MINUTES) AFTER DEVIATION OF PH TO OCCUR

CHEMICAL BUFFERS

BICARBONATE CARBONIC ACID IS AN EXAMPLE OF?

CHEMICAL BUFFERS

2ND LINE OF DEFENSE AGAINST PH CHANGE

RESPIRATORY MECHANISMS

2ND TO RESPOND (MINUTES TO HOURS) AFTER DEVIATION OF PH TO OCCUR

RESPIRATORY MECHANISMS

SLOWEST TO RESPOND (HOURS TO DAYS) AFTER DEVIATION OF PH TO OCCUR

RENAL MECHANISMS

IN ACID-BASE BALANCE, WHEN CO2 REACTS WITH WATER THE ENZYME THAT WILL CATALYZE IS?

CARBONIC ANHYDRASE

IN ACID BASE BALANCE, WHICH WILL DIFFUSE IN THE PLASMA?

HCO3-

IN ACID BASE BALANCE, WHICH WILL HOLD TO DEOXYGENATED HEMOGLOBIN

H+

TRUE OR FALSE. IN ACID BASE BALANCE, HCO3-, THE NEGATIVE CHANGBE INSIDE THE RED CELL WILL INCREASE

FALSE

WHICH IS RESPONSIBLE FOR THE INSPIRATION OF O2 WHEREIN IT WOULD DIFFUSE FROM THE ALVEOLI TO THE BLOOD

LUNGS

WHICH IS RESPONSIBLE IN THE DIFFUSION OF CO2 INTO THE TUBULE AND REACTS WITH H2O TO REFORMS WITH H2CO3

KIDNEYS

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. LACTATE

INCREASE HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. ACETATE

INCREASE HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. HCO3

INCREASE HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. IV INFUSION

INCREASE HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. DIURETICS

DECREASED HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. REDUCED REABSORPTION

DECREASE HCO3

[KIDNEYS] INCREASE HCO3 OR DECREASE HCO3. CHRONIC NEPHRITIS

DECREASE HCO3

IF ACIDOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HYDROGEN ION SECRETION

INCREASE

IF ACIDOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HYDROGEN ION EXCRETION

INCREASE

IF ALKALOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HYDROGEN ION SECRETION

DECREASE

IF ALKALOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HYDROGEN ION EXCRETION

DECREASE

IF ACIDOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HCO3- REABSORPTION AND ADDITION OF NEW HCO3 TO THE PLASMA

INCREASE

IF ALKALOSIS OCCURS IN OUR BODY, THE RENAL RESPONSE IS THERE WILL BE AN (INCREASE, DECREASE) IN HCO3- REABSORPTION AND ADDITION OF NEW HCO3 TO THE PLASMA

DECREASE

WHAT ARE THE BLOOD BUFFER?

BICARBONATE AND CARBONIC ACID, PLASMA PROTEIN, HEMOGLOBIN, INORGANIC PHOSPHATE
