What Is Septic Shock?
Septic shock is a life-threatening condition where blood pressure drops to dangerously low levels due to a severe infection. It typically develops when untreated sepsis progresses, overwhelming the body and leading to multiple organ failure. Without immediate treatment, septic shock can quickly become fatal.
The Australian Sepsis Network identifies sepsis as a major health issue, with around 15,700 new ICU cases every year and 5,000 deaths. In Queensland alone, between 2019–2020, 2,000 ICU patients died of sepsis out of 21,000 hospital admissions, showing its serious impact.
Difference Between Sepsis and Septic Shock
Understanding sepsis vs septic shock is vital for recognising early intervention needs.
- Sepsis occurs when the body reacts abnormally to an infection. Normally, the body releases chemicals into the bloodstream to fight germs, but in sepsis, this response is unbalanced, triggering widespread inflammation and organ dysfunction.
- Severe sepsis is the next stage, where toxins from bacteria damage blood vessels and further disrupt organ function.
- Septic shock is the most dangerous progression. Blood pressure drops drastically, the heart struggles to pump oxygenated blood, and vital organs begin to shut down. Without urgent treatment, death may follow within hours.
Causes & Risk Factors
Septic shock can affect anyone, but some groups are at higher risk. Newborns, older adults, pregnant women, and people with weakened immune systems or chronic illnesses are more vulnerable.
The most common septic shock causes are bacterial infections, though fungal or viral infections can also trigger it. Infections often start in the lungs, urinary tract, or gut and spread into the bloodstream.
Those at higher risk include:
- Patients recovering from surgery
- People admitted to hospital for long stays
- Individuals with diabetes, kidney, or heart disease
- Cancer patients undergoing chemotherapy
- Those with suppressed immune systems (e.g. HIV, transplant patients)
- People using IV lines, catheters, or long-term antibiotics
- Long-term steroid medicine users
Recognising these risks is key to septic shock prevention and early treatment.
Common Symptoms to Watch For
Detecting early signs of sepsis is crucial to stop it from progressing. At first, symptoms may mimic the flu but persist despite medication.
Sepsis Symptoms may include:
- Fever and chills
- Shortness of breath
- Rapid heartbeat
- Sweaty or clammy skin
- Confusion or disorientation
When the condition advances, septic shock symptoms include:
- Very low blood pressure (often needing medication to maintain ≥65 mmHg systolic)
- High fever above 38.5°C
- Rapid heart rate over 90 beats per minute
- Breathing rate over 20 per minute
- Inability to urinate for 12+ hours
- Severe pain or extreme discomfort
- Confusion, drowsiness, or disorientation
- Shivering uncontrollably
If these symptoms appear, urgent medical help is critical.
Immediate First Aid Response Steps
Shock is a medical emergency, and prompt action can save lives. If someone shows symptoms of sepsis or septic shock:
- Call emergency services (000 in Australia) immediately.
- Lay the person down and keep them comfortable.
- Check breathing and circulation—if they stop, be prepared to perform CPR.
- Do not give food or drink in case surgery is required.
- Reassure and monitor until medical professionals arrive.
Learning these skills through a first aid course provides confidence in responding to emergencies.
Prevention Tips & Best Practices
Reducing the risk of septic shock involves sepsis prevention tips and awareness of infection control.
Vaccination and Hygiene
Routine vaccinations, such as flu and pneumonia shots, can prevent infections that may lead to sepsis. Good hygiene practices—washing hands regularly and avoiding contact with sick individuals—also reduce risk.
Proper Wound Care and Infection Control
Clean and dress wounds properly to avoid bacterial infections. Seek medical help for cuts, burns, or surgical wounds that show signs of infection (redness, pus, swelling).
When to Seek Medical Help
If a fever, rapid heartbeat, or confusion persists beyond normal flu-like illness, seek immediate medical attention. Quick recognition of early signs of sepsis is one of the best ways to avoid septic shock.

FAQs About Septic Shock
What is septic shock?
Septic shock is a severe complication of sepsis where blood pressure drops dangerously low, causing organ failure and potentially death.
What are the first signs of sepsis?
Early signs of sepsis often resemble the flu—fever, chills, fast heartbeat, and confusion. If these persist, medical care is essential.
How fast can sepsis turn into septic shock?
Sepsis can escalate into septic shock within 12–24 hours if untreated, making early detection critical.
Can septic shock be prevented?
Yes. Septic shock prevention involves good hygiene, wound care, timely medical attention, and vaccinations.
Who is most at risk of septic shock?
Newborns, the elderly, pregnant women, people with chronic illnesses, or those with weakened immune systems are at higher risk.
