PULSATILE LIVER

Examination of Pulsatile Liver

Patient in 45° recumbent position

Two methods are described

Bimanual palpation (Fig. 4E.31): Place one palm over the anterior surface of the right lower

chest and other palm on the posterolateral surface of the right lower chest. Pulsations of the liver

are felt between the two palms.

Make fist of the right hand and placing the knuckles and fingers in the right lower intercostal

spaces and feel for the pulsatile liver as shown in Figure 4E.32.

(AR: aortic regurgitation; TR: tricuspid regurgitation; TS: tricuspid stenosis)

Valsalva Maneuver

The Valsalva maneuver is a forceful attempted exhalation against a closed glottis.

Instruction:

Take a deep breath, close your mouth and pinch your nose with the thumb and index finger and attempt

to breathe out gently, keeping your cheek muscles tight, not allowing the air to escape by keeping the

lips pursed.

Fig. 4E.31: Bimanual method of palpation of pulsatile liver.

intercostal spaces.

“Standard” or “quantitative”:

Blowing out with an open glottis into a tube of a sphygmomanometer against the pressure of 40 mm Hg.

Phases of Valsalva Maneuver

Physiological effects on blood pressure, heart rate and phases of Valsalva maneuver are presented in

Figure 4E.33.

Phases of Valsalva maneuver

Phase

1

The onset of blowing.

The pressure within the chest and abdomen increases and presses upon the arteries in the chest, which results in an

increase in mean arterial blood pressure (Fig. 4E.33). This activates the baroreceptor reflex, which results in an

increase in parasympathetic (vagal) activity and hence in a drop in heart rate.

The increased intrathoracic pressure also reduces the amount of blood that comes into the right atrium (decreased

venous return or preload)

Phase

2

A decrease of venous return results in a lower amount of blood that is ejected from the heart, which results in a decrease

of central venous pressure and consequently in a decrease of mean arterial blood pressure. This activates the

baroreflex, which results in a decrease of the parasympathetic (vagal) activity and consequent increase of the heart rate,

and in an increase in sympathetic activity, which constrict the arteries (an increase of peripheral resistance) and results

in a slight rise of the blood pressure at the end of phase 2 (2b).

Phase

3

Relaxation—the end of the maneuver. The intrathoracic pressure decreases, so the intrathoracic arteries widen, which

results in a brief drop in blood pressure. At the same time, the venous blood fills the heart

Phase

4

The heart ejects the blood into the arterial system against increased peripheral resistance (which has developed in

phase 2), so the blood pressure rises again (blood pressure overshoot). This activates the baroreflex, which results in a

drop in heart rate (bradycardia). Eventually, both the blood pressure and heart rate normalize

Uses

Eustachian tube dysfunction

Heart murmurs: Valsalva increases murmurs in hypertrophic cardiomyopathy and mitral valve

prolapse and decreases them in atrial septal defects and aortic stenosis.

Congestive heart failure: Valsalva responses lost.

Function of the autonomous nervous system:

An abnormal blood pressure response (for example, an absence of the blood pressure rise in

phase 4) suggests an abnormality of the sympathetic system.

An abnormal heart rate response suggests an abnormality of the parasympathetic system.

Valsalva maneuver that can be used as a provocative test to check for neurogenic orthostatic

hypotension, Chiari malformation, the Valsalva maneuver (coughing) triggers a headache at the

back of the head.

Diagnosis of inguinal hernia, prolapse of the uterus, bladder or vagina, varicocele and intrinsic

sphincter deficiency in stress urinary incontinence system.

Valsalva maneuver can help: Equalize the pressure between the middle ear and the ambient pressure

during scuba diving, driving from a steep hill, elevator descending, parachuting or plane landing or in

individuals with Eustachian tube dysfunction.

Modified Valsalva Maneuver

Modified Valsalva maneuver is used to terminate an attack of supraventricular tachycardia (SVT); it

includes blowing against a closed glottis followed by lying down face up and raising legs with the help of

an assistant, may be effective in 19–54% of cases.

Fig. 4E.33: Mean arterial blood pressure and heart rate changes during the Valsalva maneuver.

Various phases of Valsalva maneuver and its associated changes:

Phase 1 2a 2b 3 4

Intrathoracic pressure ↑ ↑ ↑ N N

Mean arterial blood pressure ↑ ↓ ↑ ↓ ↑

Heart rate ↓ ↑ ↓ ↑ ↓

Sympathetic activity ↓ ↓ ↑ ↑ ↑

Parasympathetic (vagal) activity ↑ ↑ ↓ ↓ ↑

Reversed Valsalva—Müller’s maneuver

Muller’s maneuver is the opposite of the Valsalva maneuver and includes forced exhalation followed by

an attempted forceful inhalation with a closed mouth and nose or just with a closed glottis. The test can

be used to evaluate weakness of the soft palate and throat walls in individuals with obstructive sleep

apnea.
