Blood Pressure
Force exerted against the blood vessel walls
What is systolic and diastolic?
120/80 mmHg
Systolic- force of blood against blood vessel wall during ventricular contraction 100-120

Albuterol
Glucose
Asprin (325 mg)
Oxygen
What is the use of the epinephrine?
Used for:
* severe allergic reactions
* anaphylaxis
* acute asthmatic episode ( to reduce bronchospasm)
Epinephrine causes?
vascocontriction that increases BP, heart rate and force of contaction, bronchial dilation and reduces the release of histamine.
Epinephrine can be ineffective if ?
Patient is taking beta blocker
What are adverse effects of Epinephrine?
- Cardiovascular: Tachyarrhythmias and hypertension
- Central nervous: Agitation, headache and tremors
- endocrine system : increase blood glucose
- Pregnant Female: Can decrease placental blood flow
Dose for Epinephrine?
Adult: .3mg
Child: .15mg
What is the function of Epinephrine?
Reduces hypotension, bronchospasm, laryngeal edema, prevents
additional release of histamine and other chemical mediators
What should Epi not be used with?
- ischemic heart disease
or severe hypertension
Where should Epi be administered?
Thigh
What is Diphenhydramie/chlorpheneramine?
Antihistamine or Intramuscluar histamine blocker
What is Diphenhydramie used for?
Slow to moderate allergic reactions
When the airway is not compromised
What is the difference btween Diphenhydramie/chlorpheneramine?
Chlorpheneramine does not cause as much
drowsiness
Nitrogylcerin Indications
Angina pectoris
Heart attack or heart failure
What is Nitrogylcerin?
Potent coronary vasodilator: opens up the coronary circulation
When not to give nitroglycerine?
- When the pt has viagra or levitra with 24 hrs
- Cialis within the last 48 hrs
- PT is on vasodilator ( because adding nitroglycerine will critically decrease BP)
How to administer nitroglycerine?
Adminster sublingually
* should not administer of Systolic BP is less than 90
Nitrogylcerin is given with pain of angina because what happens?
because there is a mismatch b/ oxygen demand and oxygen supply in the coronary circulation.
What are the risk of nitrogylcerine?
- If Pt is already on vasodilator and adding nitrogylcerin as another vasodilator will critically decrease the blood pressure
who are the most importanty people to ask if they are taking nitrogylcerine?
- Patients suffering from pulmonary hypertension
- on vasodilator or blood pressure management medications
How to use nitroglycerin in the forms of spray and tablet?
Tablet: Adults-1 tablet placed under the tongue or between the cheek and gum at the first sign of an angina attack,
1 Tablet every 5 mintes as needed for up to 15min.
Spray: spray in mouth, shelf life two yeats
How to administer nitroglycerine?
Administer sublingually
Administer at five minute intervals- uo to three doses
Should not administer if systolic BP is less than 90 mmHg
Oxygen is used to?
For all emergencies except for hyperventilation
Asprin
- Reduces overal mortality from MI (heart attack)
- Prevents progression of cardiac ischemia to cardiac injury or tissue death
- Check medical hx for allergy first
When such asprin not be used?
