Description

[0001] Method for providing a hypoxic and / or hyperoxic gas mixture and hypoxia training device

[0002] The invention relates to a method for providing a hypoxic and / or hyperoxic gas mixture in several cycles, as well as a hypoxia training device suitable for carrying out the method.

[0003] State of the art

[0004] The effectiveness of altitude training has long been known. Hypoxia can trigger reactions in every cell in the body and enable increased energy metabolism. It can contribute to the activation of a variety of genes. Athletes, as well as healthy and sick individuals, can benefit from hypoxia.

[0005] The state of the art in hypoxic training programs is a cyclical sequence of hypoxic (low oxygen) phases and hyperoxic or normoxic phases that are identical in terms of time and oxygen concentration, whereby the hypoxic and hyper- / normo phases can have different individual durations. The hypoxic phases have an oxygen content V(O2) in the breathing gas in a value range of 6 vol.% ± 2 vol.% <= V(O2) <= 17 vol.% ± 2 vol.%. The hyperoxic phases have an oxygen content V(O2) in the breathing gas in a value range of 32 vol.% ± 2 vol.% <= V(O2) <= 40 vol.% ± 2 vol.%. The individual duration of a hyperoxic and / or hypoxic phase is typically in the range of 1-15 minutes, with the phases usually lasting 5 minutes ± 3 minutes.

[0006] Task

[0007] It is therefore an object of the present invention to provide a method for providing a hypoxic and / or hyperoxic gas mixture in several cycles, which enables an improved implementation of hypoxia training for a user.

[0008] It is also an object of the present invention to provide a hypoxia training device that enables an improved implementation of hypoxia training for a user.

[0009] This object is achieved by means of the method according to the invention for providing a hypoxic and / or hyperoxic gas mixture in multiple cycles. Advantageous embodiments of the invention are set forth in the subclaims.

[0010] The method according to the invention for providing a hypoxic and / or hyperoxic gas mixture in a plurality of cycles comprises two method steps: In the first method step, different gas mixtures are provided in a first cycle, wherein the first cycle comprises, in a first phase with a number of sub-phases, the provision and release of a first hypoxic gas mixture during a first time interval and, in a second phase, the provision and release of a second hyperoxic and / or a normoxic gas mixture during a second time interval.

[0011] The oxygen content of the hypoxic gas mixture is selected such that all adaptation processes in the user's body are triggered, but no harm can occur from the intentionally induced oxygen deficiency. For this purpose, an initial medical history can optionally be taken from the user before the start of the procedure; in addition, the user's condition is optionally monitored in real time using sensors, e.g., a pulse oximeter. The increased oxygen content of the hyperoxic and / or normoxic gas mixture causes the oxygen content in the user's blood to rise to a normal value. With a hyperoxic gas mixture, the normal value of the oxygen content in the user's blood is reached more quickly than with a normoxic gas mixture.In the second process step, different gas mixtures are provided in a second cycle, wherein the second cycle differs from the first cycle in the number of subphases in the first and / or second phase, in the oxygen content of the first phase, in the oxygen content of the second phase, and / or the length of the time intervals.

[0012] The advantages of the invention lie in the ability to dynamically adjust the parameters of the individual phases and subphases of the cycles, thus providing a customized gas mixture that meets real-time requirements. Requirements can vary due to different times, different physical conditions of the users, and / or other different boundary conditions. These conditions can also change dynamically during the implementation of the process, thus requiring and enabling dynamic adjustment of the process parameters.

[0013] In a further embodiment of the invention, the length of the time interval of the first phase of the first cycle is different from the length of the time interval of the first phase of the second cycle. In a development of the invention, the length of the time interval of the second phase of the first cycle is different from the length of the time interval of the second phase of the second cycle. Users with health impairments can be overwhelmed by a hyperoxic phase because of increased oxidative stress. The length of the hyperoxic phase is therefore optionally regulated in real time for each user. In a development of the invention, the length of the time interval of the first and / or second phase is variable. If the oxygen saturation in the user's blood (SpO2 value) reaches an adjustable value, e.g. 90% of the normal value, a further normoxic phase is not necessary.Due to the monitoring of the oxygen saturation of the user's blood, this time is known and training can be continued with the start of another cycle.

[0014] In a further embodiment of the invention, the oxygen concentration of the gas mixture delivered in the first phase of the first cycle differs from the oxygen concentration of the gas mixture delivered in the first phase of the second cycle. The oxygen content of the gas mixture delivered in the first phase of the first cycle is greater than or equal to the oxygen content of the gas mixture delivered in the first phase of the second cycle. For the user's body, this represents a recovery period. The heart rate slows down again, and the SpO2 value rises again.

[0015] In a further embodiment of the invention, the number of phases in the first cycle differs from the number of phases in the second cycle. Demands may vary due to different times, different physical conditions of the users, and / or other different boundary conditions. During the execution of the method, parameters can be dynamically changed, thus requiring and enabling a dynamic adjustment of the number of phases of the individual cycles of the method.

[0016] In a further embodiment of the invention, the first phase comprises two subphases, each of which has a different oxygen concentration. The different oxygen concentrations, optionally in the hypoxic range, result in an optimal training effect.

[0017] In a further aspect of the invention, the lengths of the two subphases of the first phase differ from each other. Analogous to the adjustment of the different oxygen concentrations of the individual phases, an optimal training effect is achieved by appropriately selecting the duration of the individual subphases.

[0018] In a further embodiment of the invention, the sum of the lengths of the time intervals of the subphases of the first phase is constant. Thus, the subphases can have different durations, but the total duration of the subphases of the first phase is the same in each cycle.

[0019] In a further embodiment of the invention, the second phase comprises two subphases, each of which has a different oxygen concentration. The different oxygen concentrations, optionally in the hyperoxic and / or normoxic range, result in an optimal recovery effect. In a further development of the invention, one of the subphases of the second phase has a normoxic oxygen concentration.

[0020] In a further embodiment of the invention, the first sub-phase of the second phase has a hyperoxic oxygen content. This represents a recovery period for the user's body. The heart rate slows down again, and the SpO2 value rises again.

[0021] In a further embodiment of the invention, the length of the time intervals of the sub-phases of the second phase differs from one another. Users with health impairments may find a hyperoxic first and / or second phase overwhelming due to increased oxidative stress. The length of the hyperoxic first and / or second phase is therefore regulated in real time for each user.

[0022] In a further aspect of the invention, the sum of the lengths of the time intervals of the two subphases of the second phase is constant. Thus, the subphases can have different durations, but the total duration of the subphases of the second phase is the same in each cycle.

[0023] In a further embodiment of the invention, the length of the first and / or second phase and / or the oxygen concentration of the gas mixture released in the first and / or second phase is predefined before the start of training. In a further embodiment of the invention, the length of the second phase and / or the oxygen concentration of the gas mixture released in the second phase is predefined before the start of the process and optionally remains unchanged during the cycles. For this purpose, an initial medical history is taken of each user. Each user reacts individually to hypoxia training. Especially for users in a reduced general condition, regular intermediate tests such as measuring heart rate variability (HRV) should be carried out to avoid overtraining. In addition, individual influencing factors such as a tendency to hypoglycemia and the intake of medication must be taken into account when planning training.

[0024] In a further embodiment of the invention, the oxygen concentration of the supplied and / or released gas mixture of the first and / or second phase is dynamically controlled. Users with health impairments may find a hyperoxic phase overwhelming due to increased oxidative stress. The oxygen concentration and, optionally, the length of the individual phases are therefore controlled in real time for each user.

[0025] In a further development of the invention, the length of the first and / or second phase is dynamically controlled. While the length of the first and / or second phase and / or the oxygen content of the gas mixture released in the second phase remains unchanged during the cycles, the length of the first and / or second phase can be dynamically changed. Users with health impairments may find a hyperoxic first and / or second phase overwhelming due to increased oxidative stress. The length of the hyperoxic first and / or second phase is therefore regulated in real time for each user.

[0026] In an advantageous embodiment of the invention, a monitoring parameter is determined for dynamic control of the length of the first and / or second phase. In a further aspect of the invention, the monitoring parameter is a parameter from the following group: oxygen saturation of the user's blood, user's pulse, user's blood pressure, and / or a signal that allows conclusions to be drawn about the vascular condition or the stressor-related properties of, for example, excessive oxygen administration; for example, a signal that allows conclusions to be drawn about the blood flow status of the peripheral tissue, the temperature, and / or the secretion of ketones.

[0027] The user is therefore connected to a sensor, e.g., a pulse oximeter, during the procedure. Optionally, a number of monitoring parameters are determined, each of which is different from the other. This ensures redundancy and independence of the respective monitoring parameters. User safety is thus increased during the procedure, and the training effect is maximized.

[0028] In a further embodiment of the invention, a cycle has a third phase, wherein the length of the third phase and / or the oxygen concentration of the gas mixture released in the third phase is fixed before the start of training and does not change during training. For this purpose, an initial medical history is taken of each user. Each user reacts individually to hypoxia training. Especially for users in a reduced general condition, regular intermediate tests such as measuring heart rate variability (HRV) should be performed to avoid overtraining. In addition, individual influencing factors such as a tendency to hypoglycemia and the use of medication must be taken into account when planning the training.

[0029] The problem is further solved by means of the hypoxia training device according to the invention.

[0030] The hypoxia training device according to the invention is suitable for carrying out the method according to claim 1 or a method according to one of the described embodiments. The hypoxia training device according to the invention optionally comprises a gas processing device, a controller suitable for controlling the gas processing device, and an analysis device suitable for analyzing measurement data acquired by sensors coupled to the analysis device. By means of the gas processing device, in particular, the oxygen content of the gas mixture can optionally be adjusted. In addition to the gas processing device, the controller optionally also controls the number and duration of the individual phases and cycles. The analysis device is coupled to the sensors, which optionally record monitoring parameters of a user, particularly in real time.This increases user safety during the procedure, and maximizes the training effect.
