Telesair is a healthcare technology startup that specializes in the development and distribution of High Flow Oxygen Therapy (HFOT) systems. Their flagship product, Bonhawa, is designed to provide extended flow range of up to 70 liters per minute (lpm) in the US and 80 lpm outside the US. This is a significant advancement in the field of oxygen therapy, as it allows for higher flows than traditional systems, potentially improving patient outcomes.

The company's primary clients are healthcare providers and clinicians who require reliable and efficient oxygen therapy solutions for their patients. The business operates within the global healthcare technology market, with a focus on respiratory care.

Telesair's business model is centered around the sale of their Bonhawa HFOT systems. The company also generates revenue through the sale of disposable components for the system, which need to be replaced regularly for optimal performance and hygiene.

One of the standout features of the Bonhawa system is its user-friendly design. It includes a big, bright display that shows set and delivered flow, a plug protector safety latch, and a quick action display. The system is also easy to clean and disinfect, which can help healthcare providers manage more patients with fewer devices.

In terms of future growth, Telesair is focused on the integration of the latest technology into their devices, with a particular emphasis on connectivity and automation. This could potentially allow for remote monitoring and adjustment of the system, further enhancing its usability and efficiency.
