what are the five most common reasons for a medical emergency call? - Answers 1. hypoxia
2. Hypotension
3. Altered conscious state
4. tachycardia
5. Tachypnoea
The most common underlying causes of medical emergency call are attributed to - Answers 1. Sepsis
2. Cardiogenic
3. Pulmonary oedema
4. Arhythmias
What is clinical hypotension - Answers it is considered to be a 20% reduction in the patients
normal/baseline blood pressure OR 40mmHg reduction blood pressure
At what rate is systolic blood pressure hard to read - Answers systolic blood pressure less than
100mmHg are difficult to accurately measure both manually and via electronic devices
What is Mean Arterial Pressure(MAP)? - Answers is the perfusion pressure within the arteries during the
cardiac cycle- provides a better indication of perfusion to organs
what is the calculation for MAP? - Answers MAP= SBP + (2x DBP)/ 3
four cardiovascular properities are necessary to maintain adequate tissue perfusion for cellular
metabolism - Answers 1. sufficient CO (CO=SV x HR)
2. Uncompromised vascular tone (vasodilated or vasoconstriction)
3. Sufficient blood volume and blood pressure
4. Tissue are able to utilise oxygen
What is the calculation of pulse pressure (PP) - Answers PP= SBP-DBP
what is the pulse pressure? - Answers difference between systolic blood pressure and diastolic pressure
What is the pulse pressure proportional too? - Answers Stroke volume
What can low pulse pressure show? - Answers Insufficient preload, heart failure, shock state
