Doesn't have the Rho D
Universal recipient

AB+
Universal donor

O-
Normal Heartrate

60-80 bpm
Bradycardia

less than 60 bpm
Tachycardia

greater than 100 bpm
Lub
- AV Valves closing
- Immediately following QRS
Dub
- Semilunar valves closing
- Just before the T wave
Systolic
- 120
- contraction signifies pressure in the heart during contraction
Diastolic
- 80
- relaxation- signifies pressure in the heart during relxation
Flow of blood
- Body--> R. Atrium--> Tricuspid--> R. Ventricle--> Pulmonary---> Lungs
- Lungs--> L. Atrium--> Bicuspid--> L. Ventricle--> Semilunar---> Body
Electrical activity of the Heart

SA node (Sinoatrial)--> AV(atrioventricular) node--> Bundle of His--> Purkinje Fibers
Restrictive pulmonary disorders
- Occurs at the level of the alveoli which become fibrotic (hardened)
- Ability to breathe normally is difficult
- Force of air out is unaffected--> results in Lower VC, but normal Forced Expiratory Volume
Obstructive pulmonary disorders
- Occurs at the level of the bronchioles due to bronchoconstriction/mucous secretions
- Ability to breathe normally is normal however ability to force air out is affected--> normal VC but lower Forced Expiratory Volume
Respiratory acidosis
- Hypoventilation
- Increase CO2
- Increase in plasma HCO3-
- Decrease in pH--more acidic
Respiratory alkalosis
- Hyperventilation
- Decrease in CO2
- Increase in plasma HCO3
- Decrease in pH--> more acidic
