A victim is found unconscious at the roadside. As a trained rescuer, after checking the victim's response and pulse, you decide on resuscitation. What is the recommended ratio of chest compression to ventilation during CPR?
CPR Ratio: Chest Compressions to Ventilation
When performing Cardiopulmonary Resuscitation (CPR) on an unconscious victim, the standard guideline for the ratio of chest compressions to ventilations is crucial for effective resuscitation.
Recommended CPR Ratio
Current resuscitation guidelines recommend a ratio of 30 chest compressions followed by 2 ventilations.
- Perform 30 chest compressions.
- Deliver 2 rescue breaths (ventilations).
- Repeat this cycle continuously.
This ratio, represented as latex expression '$30:2$', applies to both adult and pediatric CPR for single or multiple rescuers.
Rationale for the Ratio
This specific ratio aims to balance the need for adequate chest compressions to maintain blood flow with the necessity of providing oxygen through ventilations. Frequent interruptions for ventilation are minimized while ensuring sufficient oxygenation.

- A 70-year-old man with dyspnoea on exertion has been found to have a single second heart sound and a loud diamond-shaped, rough quality systolic murmur best heard at the right $2^{nd}$ intercostal space, radiating to the right carotid artery. Which one of the following is the likely diagnosis ?
Consider the following statements with regard to pulmonary embolism :
1. Unexplained breathlessness is the most common symptom.
2. When congestive heart failure or pneumonia fail to improve despite standard medical treatment, occult pulmonary embolism should be considered.
3. Patients with high clinical likelihood of venous thromboembolism should first undergo D-dimer testing alone without obligatory imaging tests.
Which of the statements given above are correct?
