# Where is the s2 sound auscultated

## Where is S2 best Auscultated?

Also, the S3 sound is

**heard best**at the cardiac apex, whereas a split**S2**is**best heard**at the pulmonic listening post (left upper sternal border).## Where is the lub sound Auscultated?

Normal heart

**sounds**come in pairs. The**sounds**are often described as a constant “**lub**-dub,**lub**-dub.” The first “**lub**-dub” is the**sound**of the mitral and tricuspid valves closing. The second “**lub**-dub” is the**sound**of the aortic and pulmonary valves closing soon after.## Where do you hear S2 the loudest?

**Listen**for normal heart sounds: The 1

^{st}heart sound, S1 (lub), marks the beginning of systole (end of systole). Related to the closure of the mitral and tricuspid valves.

**Loudest**at the apex.

1. **Auscultate** the heart at various sites.

S1 | S2 |
---|---|

Just precedes carotid pulse | Follows carotid pulse |

Louder at apex | Louder at base |

## Where can I Auscultate S1 and S2?

Listen over the aortic valve area with the diaphragm of the stethoscope. This is located in the second right intercostal space, at the right sternal border (Figure 2). When listening over each of the valve areas with the diaphragm, identify

**S1 and S2**, and note the pitch and intensity of the heart sounds heard.## Is S1 louder than S2?

Intensity of

**S1**and**S2**: Normally, **S1** is **louder** than **S2** at the apex, and softer than **S2** at the base of the heart.

## How do I know if I have S1 or S2?

## What is S1 and S2 on thermostat?

L: This terminal is designated for indicator lights on the

**thermostat**, sometimes for when auxiliary or emergency heat is turned on, or if there’s a general problem with your system. S,**S1**,**S2**: These wires run directly outside and provide outdoor temperature information to the**thermostat**.## What does S1 and S2 mean?

The first heart sound (

**S1**) represents closure of the atrioventricular (mitral and tricuspid) valves as the ventricular pressures exceed atrial pressures at the beginning of systole (point a). The second heart sound (**S2**) represents closure of the semilunar (aortic and pulmonary) valves (point d).## What is S1 and S2 in circles?

**S1**is tangent to x-axis and

**S2**is tangent to y axis and the straight line y = mx touches both

**circle**at their common point. If centre of the

**circle S1**is (3,1), then radius of

**circle S2**is p/q, Find the least value of (p+q) Updated On: 7-12-2020. 9.7 K.

## What is S1 S11?

The equation of the chord of the circle S = 0 whose midpoint is M(x1, y1) is

**S1**=**S11**(see Fig.)## What is S11 circle?

The power of a point P(x, y) with respect to the

**circle**S = 0 is**S11**. The equation of a**circle**having the line segment joining A(x1, y1) and B(x2, y2) as diameter is (x – x1)(x – x2) + (y – y1)(y – y2) = 0. 15. Two**circles**are said to be concentric if their centres are the same.## How do you find the radical axis of two circles?

The

**radical axis of two circles**is the locus of a point which moves such that the lengths of the tangents drawn from it to the**two circles**are equal. The equation of the**radical axis**of the**two circle**is S_{1}– S_{2}= 0 i.e., 2x(g_{1}-g_{2}) + 2y (f_{1}– f_{2}) + c_{1}– c_{2}= 0, which is a straight line.## What is a common chord of two circles?

**Common chord of two**intersecting

**circles**is the

**chord**which is

**common**to

**both**the

**circles**. We can also say;

**common chord of two**intersecting

**circles**is the line segment joining points of intersection of

**two circles**as shown in the given figure.

## How do you solve a radical axis?

## What is radical line of circles?

The

**radical line**, also called the**radical**axis, is the locus of points of equal**circle**power with respect to two nonconcentric**circles**. If the**circles**intersect in two points, then the**radical line**is the**line**passing through the points of intersection.## How do you prove two circles are orthogonal?

**Two circles**are said to be

**orthogonal circles**, if the tangent at their point of intersection are at right angles. If

**two circles**are cut

**orthogonally**then it must satisfy the following condition. are

**orthogonal**. The

**two circles**cut

**orthogonally**and hence they are

**orthogonal circles**.

## How do you find the radius of a radical circle?

## What is the π?

Succinctly,

**pi**—which is written as the Greek letter for p, or**π**—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal**pi**. In decimal form, the value of**pi**is approximately 3.14.## How do you find the radius when you have the base and area?

## How do you convert area to Radius?

Divide the

**area**(in square units) by Pi (approximately 3.14159). Take the square root of the result (Example: 310.56). This is the**radius**.## How do you figure out a radius?

Divide the diameter by two.

**radius** is always half the length of its diameter. For example, if the diameter is 4 cm, the **radius** equals 4 cm ÷ 2 = 2 cm.

## How do you find circumference if you know the area?

The formula C = 2√πA is designed to

**find**a circle’s**circumference**using the**area**(A). Alternatively,**you**can solve the equation A = πR^{2}in reverse to**find**R, then plug R into the**circumference**equation. Both equations provide the same result.
