1

what % of aduts are overweight or obese

65%

2

what % of pop are obese

30

3

Mortality is almost ___x's greater in obese than non-obese

4

4

****** how to calculate IBW (KG)

Men- height(cm)-100
women- height (cm)- 105
*** 1 inch = 2.54 cm****

5

calculate IBW for a 6 foot 1 inch man and a 4 foot 11 inch woman

MAN:
6'1"= 73 inches= 182.88cm
182.88cm-100= 82.88kg
82.88kg= 182.336 lbs
Woman:
4'11"=59 inches= 149.86cm
149.86cm-105=44.86kg=98.69lbs

6

how many cm in an inch??/

2.54cm = 1 inch

7

**** how to calculate BMI***

Weight (kg)/hgt (M^2)
recorded of kg/m2

8

how many inches in 1 meter

39.4

9

Calculate BMI for a 6'9" man who weight 300 lbs

ht/m^2
HGT- 6'9'=81 inches x 0.0254=2.0574m
2.0575^2=4.23289476m^2
WGT-300=136.363636363636
BMI=136.36/4.2328947=32.21
BMI=32.21
damn!!!!!!!!

10

BMI's
Overweight-
Obese-
extremly Obese-
Super obese-
super super obese-

Overweight- BMI > or = to 25
Obese- BMI > or = to 30
extremly Obese- BMI > or = to 40
Super obese- BMI > or = to 50
super super obese- BMI> or = to 60

11

morbid obesity is calculated as what?

More than twice IBW

12

A&P of obesity head and neck with problems

-large face and neck=OSA
-thick neck, redundant tissue in airway = difficult intbation

13

A&P of obesity mobility with problems

limited mobility= increased DJD/OA

14

A&P of obesity stomach with problems

full stomach = increased aspiration and GERD

15

A&P of obesity lungs with problems

-decreased FRC, respiratory compliance and resistance, =increased hypoxemia and atelectasis
- increased blood volume O2 consumption,CO2 build up = decreased total body water

16

what does excess body mass do to CV system

- INCREASED metabolic demand and workload
-INCREASED O2 consumption
-INCREASED CO2 (chronic),
-LVH
-INCREASED SV
-cardiomegaly
-HTN
-CHF
-INCREASED Pulmonary blood flow and hypoxic pulmonary constriction
-Pulm HTN,
-COR pulmonale
- Right Heart failure

17

what does excess body mass do to respiratory system in r/t -metabolic need of excess adipose and increased work of breathing

-hypercapnia (CO2 retention)
-hypoxia (O2 consumption)

18

what does excess body mass do to the pulmonary system r/t restrictive lung disease

DECREASED FRC
DECREASED ERV
DECREASED TLC

19

clinical manifestations of obesity on CV

HTN
cardiomegaly
CHF
CAD
Pulmonary HTN
CO2 increase

20

CO2 increases by how much for each kg of adipose tissue perfused

0.1L/min

21

clinical manifestations of obesity on Pulmonary system

decreased lung volumes and capacities
arterial hypoxemia
decreased chest wall compliance
OHS-pickwickian syndrome (obesity hypoventilation syndrome)
OSA

22

S/S of pickwickian syndrome (advanced OSA)

-hypercapnia
-polycythemia
- right sided heart failure
- resp acidosis
- daytime solmnolence
- hypoventilation

23

clinical manifestations of obesity on liver

-abnormal LFTs
-fatty liver infiltration
-cirrhosis
- hepatomegaly

24

clinical manifestations of obesity on endocrine/metabolic

insulin resistance (DM)
hypercholesterolemia

25

clinical manifestations of obesity on GI system

-hiatal hernia
-gastroesophageal reflux
-gallstones
-pancreatitis

26

clinical manifestations of obesity on Pharmacology are caused by what changes

Volume of distribution
protein binding
lipophilicity
increased blood volume
decreased total body water
increased CO2

27

****what to remember about lipophilic drugs and obesity

-require higher doses (prevent under dosage)
-1st dose should be by TBW

28

***** ex on lipophilic drugs

propofol
fentanyl
midazolam
succinycholine

29

************** what to remember about water soluble drugs

- require lower dosages (prevent over dosing)
-IBW for initial dose

30

** ex of water soluble drugs

NMBD (VEC and ROC)
