During Canada's FIFA World Cup 2026 match against Qatar, Canadian footballer Ismael Kone sparked global curiosity when he was stretchered off with a serious leg injury while inhaling from a small device known as the "green whistle." The device was identified as Penthrox, a fast-acting, self-administered inhaler containing the anesthetic methoxyflurane, which is commonly used in emergency medical situations to provide rapid pain relief for moderate to severe trauma like fractures or dislocations. Designed to start working within six to ten breaths, Penthrox allows patients to manage their own pain before hospital transport, though it can cause side effects such as headaches, nausea, and drowsiness, and may be unsuitable for individuals with specific kidney or liver conditions.

Canadian footballer Ismael Kone drew concern from fans worldwide after he was stretchered off the field following a serious leg injury during Canada's FIFA World Cup 2026 match against Qatar. As he was taken away from the field, television cameras captured Kone inhaling from a small handheld device that looked like a green whistle, sparking curiosity about what he was using in such tense times.

What is the mysterious inhaling device?

The device was identified as Penthrox, a fast-acting pain relief inhaler commonly used in emergency medical situations. Penthrox, often referred to as the 'green whistle', contains methoxyflurane, which is a type of anaesthetic, designed to provide rapid pain relief for patients experiencing moderate to severe trauma.

According to the Chelsea and Westminster Hospital, Penthrox helps reduce the amount of pain you feel during a procedure, although it may not remove the pain completely.

The inhaler is frequently administered in cases involving fractures, dislocations, burns, and other traumatic injuries where immediate pain management is required before a patient can be transported to a hospital.

Unlike injectable painkillers, Pentrox allows patients to self-administer the medication by inhaling through the handheld device.

According to medical experts, pain relief typically begins within six to ten breaths. Once it begins to work, it can be inhaled as needed—either continuously or when you feel more pain.

Patients who use Pentrox may experience some of the following side effects:

  • Headache
  • Dizziness or feeling sick (nausea)
  • Dry mouth or cough
  • Drowsiness
  • Tingling skin
  • Double vision
  • Flushing or mild skin irritation

In rare cases, patients with certain kidney conditions, liver disease, or a history of adverse reactions may not be eligible to use the inhaler. For more information, consult a health expert.
