Q

What RED FLAGS can be seen in sepsis in ‘breathing’

A
  • Tachypnoea → RR >/= 25
  • Low O2 sats → oxygen required to keep SpO2 >/= 92%

16
Q

What RR is a red flag for sepsis?

A

>/= 25 (tachypnoea in general suggests sepsis)

17
Q

What SpO2 suggest sepsis?

A

Hypoxaemia (<94%)

18
Q

What symptoms may indicate the chest as the source of sepsis?

A

a productive cough with purulent sputum

19
Q

What auscultation findings may indicate the chest as the source of sepsis?

A

bronchial breath sounds and/or coarse crackles indicate consolidation (pneumonia → sepsis)

20
Q

What percussion findings may indicate the chest as the source of sepsis?

A

Dull

21
Q

What intervention should be done in ‘breathing’ in patients with suspected sepsis? Why?

A

Sit up & 15L/min oxygen via non-rebreathe mask

To try correct hypoxaemia

22
Q

What investigations should be ordered in ‘breathing’ in suspected sepsis?

A

ABG

Portable CXR

Sputum culture (if appropriate)

23
Q

How is BP affected in sepsis?

A

Hypotension

Systolic BP = 90 mmHg or a drop of >40 mmHg from the patient’s normal blood pressure is considered red flags for sepsis

24
Q

How is pulse affected in sepsis?

A
  • Tachycardia is a common feature of sepsis
  • HR >130 bpm is a red flag for sepsis
25
Q

How is CRT affected in sepsis?

A

Prolonged

26
Q

Why is it important to assess the patient’s fluid levels?

A

to inform resuscitation efforts

27
Q

How can the patient’s fluid levels be assessed?

A

oral fluids, IV fluids, urine output, drain output, stool output, vomiting

28
Q

What causes oliguria in sepsis?

A

patients with sepsis are typically intravascularly depleted due to third space fluid loss

29
Q

What is 3rd space loss?

A

this refers to losses into spaces that aren’t visible e.g. bowel lumen, retroperitoneum

30
Q

What is your response to a hypotensive patient?

A

Insert 2x wide bore cannulae (one in each antecubital fossa)

Give 500ml 0.9% saline over 15 minutes

31
Q

What blood tests

A
