Background:
Clinical positron emission tomography (PET) requires safe and effective PET radiopharmaceuticals. Tracers used for measuring oxygen consumption and blood volume are [(15)O]O(2) and [(15)O]CO, respectively. In general, these oxygen-15 labelled tracers are produced using a cyclotron that accelerates deuterons onto a target filled with (14)N(2) containing a trace of oxygen. In recent years, cyclotrons have been developed that only are capable of accelerating protons. The purpose of this study was to validate and assess such a cyclotron for production and administration of oxygen-15 labelled gasses in an hospital setting.
Methods:
An RDS111 cyclotron (Siemens-CTI, Knoxville, USA) was validated for bolus production of [(15)O]O(2) and [(15)O]CO gasses. In addition, equipment was developed to administer these tracers to patients.
Results:
Both [(15)O]O(2) and [(15)O]CO gasses could be produced in sufficient amounts, whilst meeting European Pharmacopeia requirements. Although produced oxygen-15 gasses contained a minor level of (11)C contamination, in clinical studies it was possible to correct for this contamination by delayed blood counting.
Conclusion:
An 11 MeV proton cyclotron combined with an in-house developed gas delivery system allows for the production and administration of sufficient amounts of [(15)O]-gasses for routine clinical PET studies in an hospital setting.

01:30Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

01:26Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
