Chap 30- Respiratory System Flashcards
body’s oxygen supply; eliminates waste in the form of carbon dioxide.
respiratory system
Basic Questions subjective assessment
Hx of respiratory illness
Former or Current Smoker?
Any exposure to irritants?
CO2 exposure?
Lung/CHest Sx?
Any medications (inhaler) or drugs like opioids?
S&S of Respiratory Distress
SOB
Cyanosis
Skin Mottling
Tachypnea, Rapid, Shallow Breathing
Leaning forward when sitting
Use of Accessory Muscles
What infections are a person who just undergone general anesthesia more prone to?
Atelectasis or Pneumonia
Must do’s patients should do post op to lessen risk of infections
Get up/ Be mobile
Deep Breathing
Cough
Incentive Spirometer
Upper Respiratory composes of
Mouth, Nose, and Pharynx
Lower Respiratory Tract composes of
Trachea, Bronchi, Lungs
Final destination of breathing ends in the ____
alveoli
WHy is it important to keep secretions moving in the chest?
Loosening secretions reduces risk of build up and infections
Most common way to lose alveoli?
Can alveoli regenerate?
Smoking;
Alveoli cannot be regenerated
inspiration and exhalation aka
ventilation
inspiration and exhalation is regulated by _______
The brainstem
Low CO2 does what to your breathing?
CO2 slows your breathing
Breathing does not require neuromuscular ability. T or F
False- Breathing DOES require nueromuscular ability.
PAO2 is
Partial Pressure of Oxygen
PACO2 is
Partial pressure of Carbon Dioxide
PAO2 is ________ in alveoli. Why?
PAo2 is higher in alveoli. It is good for diffusion between O2 and Blood (high to low concentration)
PACO2 is ________ in alveoli.
PAO2 is lesser in alveoli
Explain Transport mechanism in respiratory system
O2 crosses from alveoli into blood.
Blood takes O2 to tissue and organs
WHich gas regulates ventilation/ breathing?
CO2 regulates the depth and frequency of breathing
If patient has high CO2 level, how would they present and why?
Rapid, shallow/ deep breathing as they are trying to rid excess CO2
Low CO2- patient would breathe slower
Major fx of Upper respiratory tract is
to warm and humidify oxygen
Upper resp tract is Protective
Major fx of lower resp tract
- Filter and clean incoming air
- Lined w/ cilia to push unwanted things up and out
Reflexes that protect airways and lungs, reducing risk of infection
Sneeze - irritants trapped in nose stimulate sneezing, clearing nasal passage
Cough- clears lower airways
Where do secretions/mucus live?
Lower respiratory tract
Normal breathing for adult
12-20 breath per min
Exhalation takes longer than inhalation. T or F
True
Normal breaths per min for newborn- infant
30-60 breath per min
Normal breathing rate for Older adults (60 y+)
16-25
