The margin between routine and emergency is thinner than it should be.

Hypoxemic events are common, costly, and when caught early enough are often preventable.
Care is migrating to ASCs and outside the operating room, and the rescue equipment hasn't followed. Scopemed is built for that gap across four devices: O2rizon™, SlideKick™ OPA, the Ye Circuit, and the Source Control Filter Cap, each addressing a different link in the same rescue chain.

One rescue chain, three devices, no gaps.

Every hypoxemic event follows the same chain:

Detect it, open the airway, deliver positive pressure, and keep the room safe while it happens.

Scopemed builds one device for each link, designed to work together without stopping the procedure.
DETECT/OPEN

O2rizon


Oxygen delivery and breath-by-breath EtCO₂ in one mask, catches the drop before it's an emergency.

TM

ASSIST

Slidekick   OPA

One adjustable airway sized in place, the first mechanical fix for obstruction.

TM

SUPPORT

Ye   CPAP


Machine-free CPAP from the oygen already on the wall, before, durign and after.

TM

Sedation hypoxemia is common, and preventable

Finding 

Capnography monitoring cut hypoxemia from 69% to 46% during advanced endoscopy. 15

Finding 

Sleep apnea patients have 3.3× the odds of needing an airway rescue under ambulatory sedation. 4

Finding 

1 in 7 advanced endoscopy patients under propofol needed an airway maneuver. 16

Finding 

Respiratory depression is the leading cause of injury in sedation malpractice claims. 17

This is the baseline risk every Scopemed device is built to interrupt — O2rizon™'s built-in EtCO₂ is what catches it as it's happening.

Airway obstruction needs a mechanical fix first

Finding 

1 in 7 advanced-endoscopy patients under propofol needed an airway maneuver - most often a jaw thrust or an oral/nasal airway - before oxygen or pressure could help. 16

Case Report

A single adjustable distal pharyngeal airway relieved a sudden hypoxemic event mid-procedure, without aborting the case. 14

SlideKick OPA is built to be that first maneuver — one adjustable airway, sized in place, instead of reaching for a second device mid-rescue.

Positive pressure during sedation works

RCT

In obese patients undergoing endoscopy, CPAP cut hypoxia from 25% to 8%. 18

RCT

Positive-pressure preoxygenation halved hypoxemia during emergency intubation (18.5% to 9.1%). 20

Study

Before bariatric surgery, positive pressure during EGD cut desaturation from 47% to 12%. 19

Positive pressure works when it's on the patient. The Ye Circuit makes sure it can be.

CPAP across acute care

Cochrane

In acute heart failure, non-invasive pressure cut deaths by 35% and intubations by half. 8

RCT

After abdominal surgery, CPAP for hypoxemia cut intubation from 10% to 1%. 10

RCT

In acute respiratory failure, CPAP cut intubation or death from 44% to 36%. 9

Meta-analysis

Prehospital CPAP cut deaths by 42% and intubations by 63%. 21

Machine-free CPAP is proven technology

EMS precedent:

oxygen-driven, disposable CPAP has been standard prehospital care for two decades.

Electricity-free venturi CPAP (2026):

delivered up to ~65 L/min, PEEP 5–15 cmH₂O, and FiO₂ up to 100%; matched standard CPAP's SpO₂ improvement in a hypoxemic pilot.

Venturi CPAP (2020):

approved in 36 hours and deployed to 110+ NHS hospitals during COVID. 23

The Ye Circuit takes this proven physics and engineers it for the perioperative suite — with fail-safe and pressure relief valves, built-in capnography, and a mask designed for all-day wear.

Our bench data

Bench testing on device:

  • PEEP vs. inlet flow, the Ye Circuit vs. its predicate device

  • FiO₂ range and oxygen consumption at each setting

  • Pressure stability at high inspiratory demand

  • Pressure-relief and anti-asphyxia valve function

  • Capnography fidelity from the expiratory limb

Bench data; may not reflect clinical performance. Results will be published only after Regulatory review, with test method, conditions, and a controlled record reference, and logged in the claims matrix.

What the guidelines say

ASA 2014

Consider CPAP during sedation for patients already on it; continue CPAP after surgery. 24

ERS/ATS 2017

CPAP or bilevel is strongly recommended for cardiogenic pulmonary edema. 27

SASM 2016

Up to 90% of moderate-to-severe OSA is undiagnosed; cardiopulmonary events run 2–3× higher. 25

ESA/ESICM 2020

CPAP or NIV is preferred over oxygen alone for hypoxemic perioperative patients. 28

SAMBA 2012

Known OSA patients are ambulatory candidates if they can use CPAP after discharge. 26

The Ye Circuit is in development and is not available for sale in the United States. Results cited above are from published studies of positive-pressure therapy generally, not of Scopemed devices, unless otherwise stated.

Containing the aerosol: the case for source control

Review

Per-oral gastroscopy generates more aerosol than a volitional cough — the single largest event measured was a throat-numbing spray, at roughly 10× cough-level particle counts. 29

Review

Mouthpiece and filter devices in this same category have been measured cutting particle counts by >99% at the source. 29

Review

Endoscopy-evoked coughing produces more aerosol than normal breathing or a deliberate cough — exactly the reflex a sedated, obstructed airway tends to trigger. 29

These findings describe the category — aerosol-generating GI procedures and source-control mouthpieces generally — not a study of the Source Control Filter Cap itself. It's built to sit in that category: filtering aerosol at the mask while O2rizon™ or SlideKick™ OPA stays on the patient.
