ATLS 80/70/60 Rule for Palpable Blood pressure
ATLS’ 80/70/60 rule On the basis of location of pulse palpable, minimum systolic blood pressure can be predicted as follows: Radial/Dorsalis pedis/Popliteal pulse: >80 mmHg Femoral pulse: >70 mmHg Carotid pulse: >60 mmHg Overestimation of SBP by Pulses Pulse characteristics are an unreliable sign and “should be used only as…

Dental eruption : Mnemonic
Primary teeth begin eruption at around 6 months and Permanent teeth at around 6 years. In general, lower tooth erupts before it’s upper counterpart with few exceptions (lower before upper rule). Age of 6-12 years is a period of mixed dentition (eruption of permanent 1st molar to eruption of 2nd…

Developmental Milestones : Mnemonic
Principles of development Development proceeds from the head downward (cephalocaudal principle). Development proceeds from the center of the cody outward (proximodistal development). Development depends on maturation and learning. Development proceeds from the simple to the more complex. Growth and development is a sequential and continuous process. Growth and development proceed…
