Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

Source: David Guo, College of Engineering, Technology, and Aeronautics (CETA), Southern New Hampshire University (SNHU), Manchester, New Hampshire A wing is the major lift-generating apparatus in an airplane. Wing performance can be further enhanced by deploying high-lift devices, such as flaps (at the trailing edge) and slats (at the leading edge) during takeoff or landing. In this experiment, a wind tunnel is utilized to generate certain airspeeds, and a Clark Y-14 wing with a flap and slat...

Cardiac Exam I: Inspection and Palpation

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center The cardiac assessment is one of the core examinations performed by almost every physician whenever encountering a patient. Disorders of the cardiac system are among the most common reasons for hospital admission, with conditions ranging from myocardial infarction to congestive heart failure. Learning a complete and thorough cardiac examination is therefore crucial for any practicing physician.
FAQs
A parasternal heave or lift suggests increased activity of the right ventricle, making it an important clue during the cardiac examination. The finding does not establish a specific disease by itself, but it can indicate that the right side of the heart is working abnormally or under increased demand. Clinicians use it to decide whether further cardiovascular assessment is appropriate.
A displaced or forceful apical impulse can point toward left ventricular enlargement or pressure overload. Its location and character therefore provide information about possible changes in left-sided cardiac structure and workload. Because several conditions may produce similar examination findings, clinicians interpret the impulse alongside the rest of the cardiovascular assessment rather than treating it as a standalone diagnosis.
Sustained or forceful precordial movements may reflect altered heart structure or increased cardiac workload. They can support clinical recognition of hypertrophy, dilation, or significant cardiac disease when integrated with other findings. Their value lies in identifying a reason for closer evaluation, not in naming a condition independently from the broader clinical assessment.
Heaves and lifts are physical examination clues rather than definitive diagnostic tests. A parasternal or apical impulse may suggest a change in ventricular activity, size, or workload, but the finding alone cannot confirm the underlying cardiac abnormality. Clinicians therefore use it to support recognition of possible disease and determine whether investigations such as echocardiography or electrocardiography are warranted.
The clinician places a hand over the precordium, the area of the chest overlying the heart, and observes or feels for abnormal sustained or forceful movement. Attention is directed to the parasternal region and the apical impulse, because each location can provide different structural clues. This bedside assessment then contributes to the overall cardiovascular examination.
An abnormal heave, lift, displaced impulse, or unusually forceful apical movement can justify additional evaluation when it raises concern about hypertrophy, dilation, pressure overload, or significant cardiac disease. The overview specifically identifies echocardiography and electrocardiography as possible next investigations. These tests help clinicians examine the suspected abnormality beyond what palpation and observation alone can show.
When heaves or lifts suggest altered cardiac structure or workload, echocardiography or electrocardiography may provide further assessment. Their use follows the bedside finding because the physical examination is supportive rather than definitive. In clinical practice, this sequence helps connect an observed chest movement with a more detailed evaluation of possible hypertrophy, dilation, pressure overload, or other significant cardiac disease.
