Mace Windu Caused General Greivous' Cough General Grievous engaged Windu in combat when the latter tried to stop his escape. Windu used the power of the force to crush his chest plate, dealing him a massive blow to the midsection. This in turn sparked his cough, which made its way into the theatrical film.
However, before escaping, the Separatist general was caught by Mace Windu. Although he couldn't apprehend the kidnapper, Mace used the Force to crush Grievous' chest cavity. This injury resulted in the asthmatic cough that would remain with him until his death.

Why does Grievous not use red lightsabers?
His cybernetics presumably provide him with the right precision, meaning he can use any color he wishes without difficulty. And since the character's hatred for the Jedi is pronounced, it only makes sense that his “trophy” lightsabers would be exclusively green and blue: he doesn't hunt Dooku or his allies.
Grievous was originally a Kaleesh from the planet Kalee, where he lived his early life. During the Kaleesh conflict against the Huk, Sheelal quickly learned the art of war, specializing in a slugthrower rifle. Quickly amassing a great number of Huk kills, he soon became seen as a demigod among his people.
He developed a habit of collecting weapons as trophies from numerous enemies. Like others of his species, he became known for his lack of mercy and obsession with the glory gathered in war, valuing bravery in combat above all else.
Grievous was trained and designed to engage with Jedi in a way that would disadvantage them by exploiting their ways. “A Jedi uses the Force for knowledge and defense, never for attack.” The Jedi Generals in the Clone Wars were trained and raised to never use the force for attack.
The lightsaber's amethyst color was chosen by the actor portraying Windu, Samuel L. Jackson, who wanted a purple lightsaber because he was "the second baddest Jedi in the universe" and so he could find himself among the many Jedi featured in the Battle of Geonosis scene.

In both canon and Legends, Jedi will sometimes use red-bladed lightsabers in emergencies where they're missing their lightsabers and a Sith weapon is the only one available.
In the construction of a Sith lightsaber, individuals partook in a process known as bleeding. By ways of the Force, they would pour negative emotions, such as rage, hate, fear, and pain into kyber crystals. The process would result in the crystals gaining a distinctive crimson or red hue.
Sidious wasn't scared of Grievous as he served him as a means to an end, rather that he was concerned about what the Kaleesh Cyborg would do if he ever knew about Sidious orchestrating both sides during The Clone Wars.
