A system for delivery of a gas to a patient, the system comprising: a single tubular nasal cavity component (103, 203) comprising two ends (134, 135, 234, 235), the ends including a first end (135, 235) that is a gas outlet and a second end (134, 234) that is a gas inlet, the tubular nasal component configured for insertion of the first end into a nostril of a patient and adapted to maintain an inserted position, the nasal cavity component sized and configured to supply an amount of gas required by the patient through a gas flow path (137, 237) therein extending from the second end to the first end, the single tubular nasal cavity component comprising: the first end (135, 235) forming an end of a first tubular section (151, 251) having a first longitudinal axis (153, 253) along the gas flow path (137, 237), the first end flared outward towards the opening of the first end, and configured for insertion into a nostril of a patient, such that when in use, gas diverges upon exiting through the first end, a bend portion (146, 246), wherein the first tubular section (151, 251) extends away from the first end toward the bend portion; a second tubular section, which extends away from the bend portion to the second end, the second tubular section having a second longitudinal axis along the gas flow path, wherein the second longitudinal axis and the first longitudinal axis intersect at an angle of between 60 and 80° (A, C); and a tubular guidance stabilization system in fluid communication with the single tubular nasal cavity component, the tubular guidance stabilization system having gas supply tubing attached to the second tubular section of the tubular nasal cavity component, the tubular guidance stabilization system having a flexible wire or strap (174, 176) inserted along a length thereof and having a length to extend from the second tubular section, across the cheek of the user, and over the ear of the user; and whereby during use, the flexible wire or strap maintains a configuration of the gas supply tubing for supporting and maintaining secure placement of the nasal cavity component in a nostril of a user. a single tubular nasal cavity component (103, 203) comprising two ends (134, 135, 234, 235), the ends including a first end (135, 235) that is a gas outlet and a second end (134, 234) that is a gas inlet, the tubular nasal component configured for insertion of the first end into a nostril of a patient and adapted to maintain an inserted position, the nasal cavity component sized and configured to supply an amount of gas required by the patient through a gas flow path (137, 237) therein extending from the second end to the first end, the single tubular nasal cavity component comprising: the first end (135, 235) forming an end of a first tubular section (151, 251) having a first longitudinal axis (153, 253) along the gas flow path (137, 237), the first end flared outward towards the opening of the first end, and configured for insertion into a nostril of a patient, such that when in use, gas diverges upon exiting through the first end, a bend portion (146, 246), wherein the first tubular section (151, 251) extends away from the first end toward the bend portion; a second tubular section, which extends away from the bend portion to the second end, the second tubular section having a second longitudinal axis along the gas flow path, wherein the second longitudinal axis and the first longitudinal axis intersect at an angle of between 60 and 80° (A, C); and the first end (135, 235) forming an end of a first tubular section (151, 251) having a first longitudinal axis (153, 253) along the gas flow path (137, 237), the first end flared outward towards the opening of the first end, and configured for insertion into a nostril of a patient, such that when in use, gas diverges upon exiting through the first end, a bend portion (146, 246), wherein the first tubular section (151, 251) extends away from the first end toward the bend portion; a second tubular section, which extends away from the bend portion to the second end, the second tubular section having a second longitudinal axis along the gas flow path, wherein the second longitudinal axis and the first longitudinal axis intersect at an angle of between 60 and 80° (A, C); and a tubular guidance stabilization system in fluid communication with the single tubular nasal cavity component, the tubular guidance stabilization system having gas supply tubing attached to the second tubular section of the tubular nasal cavity component, the tubular guidance stabilization system having a flexible wire or strap (174, 176) inserted along a length thereof and having a length to extend from the second tubular section, across the cheek of the user, and over the ear of the user; and whereby during use, the flexible wire or strap maintains a configuration of the gas supply tubing for supporting and maintaining secure placement of the nasal cavity component in a nostril of a user.
