Pneumonia causes infected fluid to collect around the outside of the lung, called an empyema

I read online that Pneumonia causes infected fluid to collect around the outside of the lung, called an empyema.

The empyema may need to be drained with a special tube (perform suction).

My question is before the doctors or nurses peformed suction, is it necessary to count the pulses?

Or in what type of situation they need to count the pulses before suction? It was this case when the nurse used her palm to tap on the unconscious patient heart, the patient actually react by shaking the head and bubbles and saliva came out of the mouth, before they want to do the suction, they pause and count the pulse without physical contact with the patient.

Or is it they knew patient is dying and shaking the head is a sign to let go, so they did nothing and count these few seconds which is critical time, to delay any treatment and see if the patient stopped their heart beat. If not, then they will proceed with the next procedure of treatment which they think is necessary?thanks honest ans

You have your information all mixed up.

Empyema is a collection of pus, an abcess that forms in the lung.

The pneumonia fluid impacts the ability of the air to be exchanged through the tissues in the lung. Therefore you see sputum and liquid in the mouth when they are severely ill.

Empyema must be removed by inserting a drainage tube through the side of the patient. (chest tube).

Suction of a patient is a tube down the throat.
