Upper respitaroty system
composed of
considered
Composed of:
nose,
sinuses,
pharnyx,
larynx,
trachea
Considered the Air movement passage way
lower respiratory system
composed of
largest component
pulm art/veins
Composed of:
lungs
,bornhi,
brochioles
Largest component- Lungs
pulmonary arteries-deliver deox blood to lungs
pulmonary veins -delvier ox blood to heart
why are lungs subdivide into lobes
alveoli are responsible for
lungs subdivided in lobes- right-3, left -2 ,so that if one is damges lungs cans till work
Alveoili are responsible for air supply.the air sacs fill up and passes through alveolar walls for co2 and o2 gas exchange
art of reparation
c02 travels from blood into alveolar cells and then exhaled
02 travels from alveolar cells into blood and is circulated into tissues
factors affecting respirations
Volume & Capacity-
Air Pressure –
O2, Carbon Dioxide & Hydrogen Ion Concentrations –
Surfactant-
Airway Resistance, lung compliance & elasticity-
volume and capacity are affected by
gender
age
weight
health
why is air pressure necessary
necessary to maintain expanded lungs
Inhalation- airflow into lungs -diaphragm contracts downwards
Exhalation- airflow out of lungs-diaphragm relaxes upward and intercostal spaces relax, reduces space forces air out
how does 02,co2 and hydrogen ion work
rate and depth is controlled by respiratory centers, brain detects changes in co2 and alters breathing accordingly
how does surfactant work
reduces surface tension in lung fields, helps expands lungs by keeping alveoli open
how does airway resistance
lung compliance
elsacticty
as resistance increases, gas flow decreases.
Compliance is the distenbiality and is reliant in the lungs .
Decrease elasticity impairs respirations (emphysema)
assessing repsitaroy function

Physical Assessment
Inspection & Palpate –bulgings or retrations
Auscultation –all fields listgen to anteriot and posterior, clear, diminished, rub,wheezes
Percussion –dullness could mean pneumonia,atalecasis
hypernemisis- emphanima or asthma/pnemothorax
Lab values low rbc= decreased tissue oxygenation-could be confused
Vital Signs
vital signs
what is spo2 measuring
Spo2 is measuring amont of hemoglobin that is carrying oxygen in the blood
Pulse ox measures using light sensors by measure how much blood is carrying o2
Viral Upper Respiratory Infections
known
peaks
Knowns as URIs or common cold-highly contagious-
peaks during sep to jan
viral uri
Patho
over__
spreds
contagious
inflammation
mucus
over 200 strains,
droplet spreads through sneezing coughing or direct contact. spreads when hands and fingers pick It up
Contagous prior to and after symptom devlopemnt.
Inflammation is when the body is trying to trap the organism and kill off-
mucus secretions trap invading organism by being hyperactive
viral uri manifesations
nasal mucus passway swells
, sneezing,
coughing-loose,wet or non productive,
sweating
fever,
sore throuat-initial symtpom
. Nasal mebranes red and swollen,
clear secretions leading to coryza(nasal inflammation and discharge)
viral uri diagnosis
self care
Diagnosis H&P, presentation of symptoms, wbc count, cultures of purulent discharge.
Self care is appropriate. Trearmetn is required when sinitus or ottitus media devlop
how to manage uri
nursing interventions
adequate Rest,
maintain high fluid intake ,
pain/fever meds
,cough managmaent, covering when coughing and sneezing
hygiene,
avoiding crowds,
washing hands,masks.
Nursing Interventions C&DB-prevents pneumonia-know of effective by listening to lung sounds, monitor pulse ox, assess repirory rate
Auscultate lung sounds, monitoring pulse ox, assessing respiratory rate
medications uri
other therapies
Decongestants, antihistamines, nasal sprays
Complementary Therapies
Herbal tea,
,essential oils,
vitamin c,
zinc
accumputure,
garlic,,
essential oils such as basil, cedarwood, eucalyptus, frankincense, lavender, marjoram, peppermint, or rosemary can reduce congestion and promote comfort and recovery.
health promotion and continuity of care uri
promotes-breathing,airways clearance,reduce infections
Avoid Crowds, rest, hand hygiene, stress
promots effective breathing-monitor rr , pace activies for rest,elevate hob,//
promote aireay clearance, cough and seceretions, hydration and increase humidity and inspired air,teach cough tehcniques//sleep qlait-sleep patters//
reduce risk of infection—standarg precatiuiins, control secretions by mainating distance,, droplet precations,mask and priv room
decongestants
Phenylephrine (Neo-synephrine),
pseudoephedrine (Sudafed),
oxymetazoline (Afrin)
decongestants
vasoconstriction
reducing inflammation and edema within head and relieves congestion. Habit forming and can cause rebound congestion. Can lead to chroninc congestion and inflammtion
what need to know as rn
decongestants
pt education
Cardiac contraindications asses for hypertion and heart disease. Will increase hr and bp
Medication interactions maoi inhibitors and antihypertensive drugs
pt education decongestants
safe dose,
cardiac history,
nasal spray–not to use for more then 5 days, can cause jittery and hyper and can cause insomnia/sleeplnesness
antihistamines
Diphenhydramine (Benadryl),
Cetirizine (Zyrtec),
Loratadine (Claritin)
antihistamines
what do
OTC allergy and cold medications
Relieve histamine dry secretions up.
what need to know as rn and pt education antihistamines
Assess for asthma or lower respiratory disease
Effects drying. Sedative some are more then others.
Activity tolerance and safety and sleepiness
Patient Education no alcohol due to sedation
respiratory syncytial virus
primary cause
who gets
Primary cause of respiratory illness In Young children and infants
Older children and adults more likely to present
Elderly and immunocompromised more susceptable
trasnmissopn of rsv
similar to ur. Can get through
droplet
object,
coughing and sneezing
via contaminated hands or objects
manifestations RSV
rhinorrhea,
common cold
,and cough
children can progres to pneumonia or brovnciolitis
treatment of rsv
supportive care, similar to ur.
Intubation only necessary when in lower lungs and hypoxia
develops hydration and mobilizing secreations.
diagnosis/meds for rsv
Diagnosis is
history/clinical findings,
wbc count
Meds-ribravian in older adults

Reduce risk of infection-standerd precaution-instruct patients to maintain distance of 3 feet, droplet precautions, priv room and masks
sinitus
what is
any process
follows
inflammation of mucus membranes-develops when swell
Any process that impairs drainage from the sinuses may precipitate sinusitis. Examples include nasal polyps, deviated septum, rhinitis, tooth abscess, and swimming or diving trauma
Follows an URI, influenza-seceations collect in cavities. Draws serum and loekoctyes and causes increases swelling and pressure
manifestations and complications of sinitus
manifestions
Pain/Tenderness across infected sinus
Heachache
Fever
malaise
Pain in leaning forward and up teeth
Nasal congestion, discharge/bad breath
complications
menengitis,
brain abcess
Discomfort in neck may mean spreading issues
Periorbital Abcess,cellulitis,sepsis or intracranial pain
how diagnose sinitus
Presentation of symptoms h and p
Imaging x ray- normally translucent, cloudy and pink
Ct and mri may be needed to rule out chroninc sisues
how is sinitus treated
antibiotic therapy-10-14 days w/ amxocillan or ciroflaxon
steroids/decogestants-dry secretions, not as effective
saline-promotes drainage
no response = surgery
nursing care sinitus
manage pain scale, ice pack, elevate hob//
nutrition
clear liquid diet
I and o
elevate hob//
tonsillitis

caution in children
‘
tonsillectomy
Ice collar, cool fluids, ice chips, warm saline, liquid diet/semi liquid,assess pain, adnminster analgesucs
Take caution with asprin in children. Don’t eat acidic or citrus foods/drinks. No forcful gagling. Can cause blleding—can only do gentle saline gargles
Laryngeal Infection: Epiglottitis

includes
inflammation=
Located between upper airway and lungs and protects lower repertory tract from inhaled subatacnes and allows speach
Includes the epiglottis
Inflammation of these structures = epiglottis or laryngitis
epiglottitis
type of infection
