Pulmonary Shunt/Dead-space Ventilation | allnurses

I am in my last semester, taking high acuity. A few of us are having a hard time getting our brains around V/Q mismatch, shunts, and dead-space ventilation.

Figure 1: Different shunting options for first stage palliation of HLHS, shown from idealized drawings: (A) modified Blalock-Taussig shunt from the innominate artery to the right pulmonary artery; (B) Sano shunt from the right ventricle (Rv) to the pulmonary artery (Pa); (C) central shunt from the ascending aorta (Ao) to the pulmonary artery.

Vivien Thomas was a key player in pioneering the anastomosis of the subclavian artery to the pulmonary artery.The surgical work he performed with Alfred Blalock paved the way for the successful outcome of the Blalock-Taussig shunt. Unable to attend college for lack of money, Thomas began as Dr. Blalock's lab assistant, but his skill in designing surgical tools and inventing surgical techniques made him invaluable. His work was unrecognized until late in his life because he was…

Respiratory failure - advanced   Level: ICU Nurses.  Love, love, love this webpage.

The most common cause for hypoxaemic respiratory failure in ICU patients is perfusion of non-ventilated alveoli (shunting).

Atrial-Septal Defect (ASD). Congenital, acyanotic, heart defect in which the atrial septum does not fully close, and oxygenated blood from the left atrium is shunted to the right atrium. The majority of ASDs are well-tolerated, and as long as they remain left-to-right (thus acyanotic), they can be asymptomatic. A long-term increase in pulmonary blood flow can eventually lead to pulmonary hypertension, and a shunt reversal.  Large or symptomatic ASDs are surgically corrected early in life.

What is an atrial septal defect (ASD)? An ASD is a hole in the wall of tissue that separates the right and left atria (septum). The ASD is a congenital defect (present at.

Left-to-Right Cardiac Shunts (Heart) Types and Symptoms

Multiple small round nodules on CXR. Differential includes metastases, granulomata, hamartomata, and pulmonary arteriovenous malformations. pAVMs may be asymptomatic or cause symptoms due to a right-to-left shunt (dyspnoea and embolism). CT shows feeding pulmonary arterial branch and draining pulmonary venous branch.  #FOAMrad #FOAMed #radiology

Atrial septal defect causes left to right shunt due to the high compliance of the right atrium and the difference in pressure between the two atria. Secondary to this mechanism, the pressure in the pulmonary circulation is increased.
