Q

What is cystic fibrosis?

A
  • Chromosome (gene) mutation, inherited
  • Body produces thick sticky mucus in the lungs and blocks pancreas which stops the body from properly absorbing food- malnourished, weaker immune system. May impact liver and cause cirrhosis
  • Avg. life expectancy 32 years
  • Results in airway dehydration
133
Q

What could airway dehydration cause in those with cystic fibrosis?

A
  • Produces thick mucous
  • Adheres to airway surfaces
  • Leads to infection, inflammation, obstruction

134
Q

What is cystic fibrosis characterized by?

A

recurrent respiratory tract infections and progressive respiratory insufficiency

135

Inhalers

Pills

OT: managing and working around it during ADLs

144

Vocational modification or rehabilitation

145
Q

What are the 3 graft sites for a CABG

A

saphenous vein from leg

radial artery from the arm

internal mammary artery from the chest wall

146
Q

What is a bypass pump?

  • also called heart-lung machine
  • Does the work of the heart and the lungs when the heart is stopped for a surgical procedure to maintain blood circulation and oxygen content of the body
  • may be used in a CABG
147
Q

A

Slows heart rate and surgeons developed ways to stabilize a beating heart

148
Q

Where are the CABG incisions located?

A
  • minimally invasive: 2-3in incision in chest wall between ribs
  • traditional CABG: 6-8in incision made down center of sternum
149
Q

Purpose of precautions following CABG

A
  • used to help protect sternum
  • to prevent the sternum from coming apart from an injury
  • prevent pain and bleeding
150
Q

Sternal precautions include..

A
  • Limit horizontal abduction/Limit bilateral arm extension
  • No lifting greater than 10lbs
  • Hold a pillow when moving, sneezing or coughing
151
Q

What are parameters vital signs?

A

MD may specify certain parameters for BP or HR during activity (IE no activity is BP is >180/100)

152
Q

How do you calculate how much 02 is left in an O2 tank?

A
  • Minutes remaining = PSIG x F/ LPM
  • PSIG = pounds per square inch gauge
  • F = factor
  • LPM = liters per min (Rx)

-So, if there’s 400 PSIG left in an E tank (.28 factor) and the patient is on 4 LPM
(400 * 0.28)/4= 28 minutes of O2 remaining in the tank
