Buffers

Respiratory

resp system controls the Co2 and O2 in the lungs. If the Co2 rises it could lead to kusmaul resp.

alkalosis - hyperventilation, pH increases, Co2 directly decreases your carbonic acid.

Acidosis - Co2 increase and directly increase the carbonic acid. RR decreases and the depth decreases

Renal

RAS system holds back water or sends it into waste, depending on how much sodium. It will also reabsorb bicarb or excrete based on the pH level. The kidneys can also produce bicarb levels if too low. Impaired in renal disorders.

Buffer System

combine or release the hydrogen ions to make the ph stable.
First line of keeping stable ABGs/VBGs
there is a natural way to maintain homeostasis

The other systems - bicarb is a buffer, but the renal system is controlling. Co2 in the resp system.

3 different chemical buffer systems
- protein - attracts depending on the charge - or +
- phosphate - internal of all cells. there is a weak acid and a weak base, the latter can bind the hydrogen to hcl to form the weak acid and NacL.
- resp and renal

RBC and hemoglobin - if we do not have enough then we will have issues with hemoglobin getting into the cells.

un-compensation

body is trying to adjust to create homeostasis
see normal values
you keep doing this until your body tires out.
it can be simple, too much Co2 breath faster - YOUR BODY is DOING it

compensation

jleavitt5 — 2022-08-30 19:49:53 UTC

when body is in this, you are not able to regulate and can not keep in ranges so you will see abnormal ranges
intervention needs to occur
*Remember the system MUST compensate for the ABNORMAL value

Normal Values

jleavitt5 — 2022-08-30 19:54:56 UTC

pH 7.35-7.45
Co2 35 - 45
HCo3 22-28

2022-08-30 19:55:28 UTC

Ph 7.35-7.45

jleavitt5 — 2022-08-30 19:56:54 UTC

< 7.35 --> acidosis, increase of hydrogen ions in the body

> 7.45 --> alkalosis, decrease of hydrogen ions in the body or an increase of bicarb.

PCo2- 35-45

jleavitt5 — 2022-08-30 19:58:11 UTC

< 35 --> alkalosis

>45 --> acidosis

Hco3 22-28

jleavitt5 — 2022-08-30 19:58:46 UTC

< 22 --> acidosis
>28 --> alkalosis
