A

Fever, weight loss, cough- often with haemoptysis.

35
Q

hyperventilation syndrome

A

rate of breathing exceeds metabolic demand. It is higher than what is required to maintain normal CO2 levels.

36
Q

causes of hyperventilation syndrome

A

PE, diabetic ketoacidosis, asthma, hypovolemia (lack of blood), emotion stress or anxiety.

37
Q

signs and symptoms of hyperventilation

A

acute anxiety, tetany, carpopedal spasm, numbness and tingling of mouth and lips, aching of chest, feeling lightheaded.

38
Q

management of hyperventilation

A

open airway, O2 if cyanosed, maintain calm approach, coach respiration and encourage talking, DO NOT USE a paper bag or anything else for the patient to breath into.

39
Q

Name the 4 industrial lung disease

A

Pneumoconiosis, silicosis, asbestosis, byssinosis.

40
Q

tension pneumothorax

A

air enters pleural cavity through open chest wound but tissue acts as one way flap so pleural cavity increases, decreasing lung capacity.

41
Q

signs and symptoms of tension pneumothorax

A

dyspnoea, panic, cyanosis, haemoptysis, pain at site, tachycardia, tachypnoea, asymmetry of chest.

42
Q
