Intro to Pathophysiology Flashcards
Pathophysiology
-Study of disease and injury
-Changes in physiology of the body
Patho =
abnormal
Disease
-Disruption in homeostasis
Physically, Mentally, and socially
Homeostasis
-Tendency to maintain equilibrium
-Steady state of internal chemical and physical conditions
Normal Temp
98.5 F (97.1-99.5F)
Normal oxygen saturation
90-100% ??
Normal RR
12-20 RR
What 3 factors make up disease?
- Conductive Environment
- Susceptible Host
- Pathogen
Intrinsic factors of disease
- Genes (mutations)
- Immunity
- Age (older or very young)
- Gender (PSA vs Uterine)
Extrinsic factors of disease
- Bacteria
- Viruses
- Injury
- Behaviors (smoking, drinking)
- Stressors
- Fungi
What is the process of disease?
- Identification- S/S (Objective vs Subjective)
- Occurrence- How often vs When
- Diagnosis- Identification
- Etiology- Cause
- Prognosis- Likelihood of recovery
Stages of disease
- Exposure-Where the person got sick
- Onset- How quickly signs & symptoms occurred
- Remission-Disease no longer active
- Convalescence- Recovering from disease
Sudden
Woke up and symptoms there when healthy the night before
Insidious
-Slow and gradual
-Common in chronic or slow to develop diseases
-Unaware until disease progresses
Ex. GI bleed
Latent
Not active but lies in weight
Ex. Chicken pox turns into shingles
Prodromal
Presymptoms
Ex. Chills before Flu
Manifestations
Signs and Symptoms
Idiopathic disease
-We don’t know what the cause is
-Unknown
-We might have ideas or theories
Ex. Heart Failure
Latrogenic diesease
-Caused by some treatment
-A medical cause
-Ex. Hospital acquired infections, pressure ulcers, med errors, surgical errors
Exacerbation disease
-Worsening of a disease
-Acute decline in a persons chronic disease
Ex. Asthma
Hypo-

Hyper-
Above, over
-penia
lack of, deficiency
-cytosis
refers to cells, increase
-osis
-process or condition
-production or increase
-invasion or infection
-itis

-pathy
disease or suffering
