Nasal and oral patient interfaces

A patient interface comprising:

• a U-shaped body portion configured to communicate with a first fluid path, the body portion being configured to engage an exterior surface of the nose of a patient responsive to being donned by a patient;
• a U-shaped first nostril interface extending from the body portion wherein the nostril interface communicates with the first fluid path, and herein the first nostril interface is configured to extend generally over an end of the nose of the patient and into a first nostril of the patient responsive to being donned by a patient and is sized and configured such that the first nostril interface does not completely block the first nostril responsive to being donned by the patient;
• a first tubing that defines the first fluid path, where the first tubing is coupled to the first nostril interface;
• a first securement portion extending from the body portion proximate the first nostril interface, wherein, in use, the securement portion is constructed and arranged to engage are exterior alar sidewall surface of the patients nose to clamp the body portion to the patient's nose and to secure the patient interface to the patients nose, and wherein a resiliency of the first securement portion and the first nostril interface is configured to, enable clamping of the alar sidewall portion of the patients nose therebetween;
• and
• a physiological function sensor connected with the first securement portion for engagement with the skin of the nose of the patient, and herein the physiological function sensor generates a signal based on a physiological function measurement,
• wherein the body portion includes an oral sampler configured to communicate with the first fluid path through at least one conduit internal to the body portion.

A patient interface comprising:

• a U-shaped body portion configured to communicate with a first fluid path, the body portion being configured to engage an exterior surface of a nose of a patient responsive to being donned by a patient;
• a U-shaped first nostril interface extending from the body portion, wherein the nostril interface communicates with the first fluid path, and wherein the first nostril interface is configured to extend generally over an end of the nose of the patient and into a first nostril of the patient responsive to being donned by a patient and is sized and configured such that the first nostril interface does not completely block the first nostril responsive to being donned by the patient;
• a first tubing that defines the first fluid path, where the first tubing coupled to the first nostril interface;
• a first securement portion extending from the body portion proximate the first nostril interface, wherein, in use, the securement portion is constructed and arranged to engage an exterior alar sidewall surface of the patients nose to clamp the body portion to the patient's nose and to secure the patient interface to the patients nose, and wherein a resiliency of the first securement portion and the first nostril interface is configured to enable clamping of the alar sidewall portion of the patient's nose therebetween;
• and
• a second securement portion constructed and arranged to engage an interior surface of a patient's nose such that a portion of a nose is disposed between the first securement portion and the second securement portion,
• wherein the body portion includes an oral sampler configured to communicate with the first fluid path through at least one conduit internal to the body portion.

A patient interface comprising:

• a body portion configured to communicate with fluid path, the body portion being configured to engage a surface of a nose of a patient responsive to being donned by the patient;
• a nostril interface extending from the body portion, wherein the nostril interface communicates with the fluid path, and wherein the nostril interface configured to extend into a nostril of the patient responsive to being donned by the patient;
• a tubing that defines the fluid path, where the coupled to the nostril interface;
• and
• a securement portion extending from the body portion proximate the nostril interface and being configured to damp the body portion to the patient's nose and to secure the patient interface to the patients nose,
• wherein the body portion includes an oral sampler configured to communicate with the fluid path through at least one conduit internal to the body portion.
