Because the clots block blood flow to the lungs, pulmonary embolism can be life-threatening. stridor. The sound is similar to snoring. Like wheezing, rhonchi is caused by fluttering air movements but through the larger airways (like the bronchi).. This harsh, noisy, squeaking sound happens with every breath. It is caused by fluttering air movements produced either through a narrowing or partial obstruction of or pus or accumulated fluids within the smaller airways (like bronchioles).
