Q:l Gerontologicl Considerations:Effectsl ofl Agingl onl Respiratoryl System

Answer:

•Structurall changes-l barrel-shapedl chest,l musclel strengthl declines,l lungsl arel harderl tol inflate.l Functionall alveolil decreases,l lessl elastic.

•Defensel mechanisms-l lessl forcefull cough,l lessl functionall cilia,l mucousl membranesl tendl tol bel drier.

•Respiratoryl control-l graduall responsel tol changesl inl bloodl oxygenl orl carbonl dioxidel level.

Q:l Manifestationsl associatedl withl geriatricl population?

Answer:

-ALOC -CNSl depression

Q:l Arteriall Bloodl Gassesl (ABGs)

Answer:

•ABGsl arel measuredl tol determinel oxygenationl statusl andl acid-basel balance.-Representsl homeostasis

Q:l ABGl analysis

Answer:

PaO2,l PaCO2,l acidityl (pH),l bicarbonatel (HCO3-),l andl SaO2.

Q:l pHl level

Answer:

7.35-7.45 2 / 4

Q:l PaCO2l normall range

Answer:

35-45l mml Hg

Q:l Bicarbonatel (HCO3)

Answer:

22-26l mEq/L

Q:l Respiratoryl Acid-Basel Imbalance

Answer:

-Respiratoryl Acidosis -Respiratoryl Alkalosis

Q:l Respiratoryl Acidosis

Answer:

•CO2l retentionl froml hypoventilation •Decreasedl plasmal pH

•Examplel ABG:

-pHl 7.31 -PaCO2l 54l mml Hg

•Potentiall Causes:

-↓RRl (Resp.l acidosis) -Atelectasis -Opioidl abusel (causingl resp.l depression)

Q:l Respiratoryl Alkalosis 3 / 4

Answer:

•CO2l excretionl froml hyperventilation •Increasedl plasmal pH •

•Examplel ABG:

-pHl 7.52 -PaCO2l 27l mml Hg

•Potentiall Causes:

-↑RRl (Resp.l alkalosis) -Anxiety,l fear -Sepsis -Pain

Q:l Metabolicl Acidosis

Answer:

•Decreasel inl plasmal pH •Decreasedl HCO3

•Examplel ABG:

-pHl 7.29 -HCO3l 18l mEq/L -

•Potentiall Causes:

-Diarrheal -Starvation -DKA

Q:l Metabolicl Alkalosis

Answer:

•Increasedl plasmal pH •Increasedl HCO3 •
