Factors that Affect Pulse Pressure (3)
- *1. Stroke volume**
- Stroke volume PRIMARILY affects (and is proportional to) systolic blood pressure
- Increased stroke volume = increased systolic pressure
- Decreased stroke volume = decreased systolic pressure
- *2. Systemic vascular resistance (SVR)**
- SVR PRIMARILY affects (and is proportional to) diastolic blood pressure
- Increased SVR (vasoconstriction) = increased diastolic BP
- Decreased SVR (vasodilation) = decreased diastolic BP
- *3. Aortic compliance**
- If the aorta has good vascular compliance (like in younger, healthy patients), the systolic pressure will be lower during systole
- If the aorta is noncompliant/“stiff” (like in older patients), systolic pressure will be much higher during systole
- In other words, systolic pressure (and thus pulse pressure) is inversely proportional to aortic compliance

Estimated Weight Loss (EWL)
Estimated Weight Loss And Dehydration
- Notice how younger children can better tolerate volume loss (i.e., they it takes a higher overall volume loss before they are considered “dehydrated”
- This is due to the fact that younger have higher circulating blood volumes (per kg), so water takes up a larger portion of their total body weight (i.e., they have more water to lose) - Older children can’t tolerate as much volume loss (in mL/kg), because water takes up a lower percentage of their total body weight (i.e., they don’t have as much water to lose)
- Dehydration can lead to hypotensive (non-hemorrhagic) shock

Back to “Evaluate, Identify, Intervene” (EII)
Steps to Diagnose and Follow in Each Scenario
- Start out with the initial ABCs (Appearance, Breathing, Circulation)
- Check responsiveness
- If unresponsive, check pulse, activate EMS, & start resuscitation - Start the primary assessment (ABCDEs) with C-A-B
- Check signs of perfusion (color, capillary refill, strength of pulse, temperature, etc)
- Verbalize “monitors, IV, oxygen (if needed)”
- Also remember to auscultate and check for breathing difficulty - Finish the primary assessment by completing the “D & E” steps
- Get a glucose/check pupils/AVPU
- Look over the child for any bodily abnormalities (i.e., signs of trauma) - Intervene (start therapy) at the earliest appropriate time during the primary assessment
- For instance, the “monitors, IV, oxygen” count as an intervention - Reevaluate by performing the secondary and diagnostic assessments while your initial intervention is going on
- In other words, “what happened?” How did the child get to this state?”
- Verbalize “SAMPLE” the H’s & T’s (more for cardiac arrest patients)
- Get labs and diagnostic tests (CXR, ultrasound, etc) - Intervene again, based on the additional information
- Fluids, breathing treatments, etc - Frequently reassess the patient to determine the next step
- Determine if the child’s condition is improving based on the initial interventions
- Determine whether or not additional interventions are necessary - Intervene again and continually reassess after every intervention
