Adrenaline Flashcards
What is Adrenaline?
naturally occurring hormone
symp-atho-mimetic drug,
it mimics the effects of naturally occurring adrenaline.
What are the three main types of adrenergic receptors?
The three main types of adrenergic receptors are Alpha 1, Beta 1, and Beta 2.
What does Alpha 1 activation do?
vasoconstriction, increasing systemic blood pressure.
What does Beta 1 activation do?
increases heart rate, contractility, and automaticity.
What does Beta 2 activation do?
bronchodilation, improving oxygen exchange.
What is the outcome of Alpha 1 activation?
Increased systemic blood pressure, enhancing blood flow to the heart and brain.
What is the outcome of Beta 1 activation?
Increased heart rate and contractility,
improving the chances of heart restarting during cardiac arrest.
What is the outcome of Beta 2 activation?
Enhanced bronchodilation, facilitating better oxygenation of vital organs.
Why is adrenaline administered for Alpha 1 activation?
To increase systemic blood pressure.
Why is adrenaline administered for Beta 1 activation?
To enhance heart rate and contractility.
Why is adrenaline administered for Beta 2 activation?
To improve oxygen delivery and gas exchange.
What does ‘perfused’ mean?
Adequate blood flow and oxygen supply.
What is ‘gaseous exchange’?
The exchange of O2 and CO2 in the lungs.
What is ‘contractility’?
The ability of heart cells to contract.
What is ‘automaticity’?
The ability of heart cells to spontaneously contract.
What are adrenergic receptors?
Receptors affected by adrenaline and related medications.
Why is understanding adrenaline important in paramedic practice?
Understanding the role of adrenaline in cardiac emergencies is crucial for effective paramedic practice.
